  - no changes since 2.2100

2.2100   2021-04-13 (TRIAL RELEASE)

  - a test has been rewritten so as to remove IO::String from the prerequisite
    list (#179, thanks Ricardo Signes!)


  - optional prereq on List::SomeUtils has been replaced with List::Util 1.56.

  - Include details about expected values when Enum type checks fail (#174;
    thanks sherrardb)


  - fix misleading missing semicolon in exceptions example (#170; thanks

    permissions being captured (possibly unintentionally) by others.
  - Sub::Identify prerequisite removed, in favour of already-existing local

2.2013   2020-07-21


  - improved some documentation wording in Moose and Class::MOP::Class
    (PR#162; thanks Tom Hukins!)


  - updated bundled ExtUtils::HasCompiler, for msys2 support (RT#133022)

2.2012   2019-11-22


  - adjust test of missing package to accomodate new diagnostic message in

2.2011   2018-05-16


  - Various native trait methods would refuse "0" where they expected a
    string.  They have been fixed to allow all defined, non-reference values,
    and all objects with string, number, or boolean overloads.


  - Moose::Manual::Construction now notes that roles can modify the BUILD sub.
    (thanks, E. Choroba!)


  - adjustments have been made to the Makefile for 'bmake', so it now works
    when not run in compatibility mode (Leon Timmermans).

2.2010   2018-02-16


  - A performance improvement with operator overloads has been made by making
    use of a new Devel::OverloadInfo interface (thanks, ilmari!)

2.2009   2017-11-29


  - Some hash native trait methods (notably clear and delete) were broken in
    various ways when the associated attribute's type allowed for coercion of
    the hash values and coercion was enabled for the hash. Reported by Ralf
    Bartel in RT #123737.


  - fixed tests (new in 2.2008) that sometimes fail under Windows.

2.2008   2017-11-21


  - fixed empty exception messages under -d (new issue in 2.2007)

2.2007   2017-11-12


  - The Moose::Manual::Attributes pod has been amended to clarify that
    'required' attributes can be satisfied with a 'default' or 'builder' sub,
    and that 'ro' attributes can be set through the constructor.

  - The Moose::Manual::Types pod has been amended to recommend
    Params::ValidationCompiler and Moops instead of older modules (which are
    slow and/or deprecated).

  - other small documentation fixes (thanks to Chris Weyl and Anirvan


  - some dead code has been removed (thanks, Jens Berthold!)

  - all Moose exception classes have been made immutable.

2.2006   2017-07-12


  - Passing roles as a mix of role names and role objects to
    Moose::Meta::class->create_anon_class could throw a bogus exception about
    'Roles with parameters cannot be cached ...'. Fixed by Olivier
    Mengué. Based on PR #117.

2.2005   2017-05-03


  - increased minimum required version of Test::More, to ensure a reliable

2.2004   2017-01-31


  - When an attribute was specified as 'rw' and you also provided an accessor
    name matching the attribute and there was an explicit writer, Moose would
    try to make an additional reader access with the same name as the
    attribute. Then Moose would warn about overwriting an accessor with a
    reader. This is related to the bugs reported in RT #120040.

2.2003   2017-01-30


  - Moose could die when attempting to warn about overwriting an attribute's
    access method in some cases (since version 2.1902) (RT #120040)

2.2002   2017-01-30


  - Creating a Moose subclass of a Moo class with an attribute with a
    delegation would cause a warning (since version 2.1902).

2.2001   2017-01-29


  - fixed variable interpolation in filename in test (RT#120033)

2.2000   2017-01-29


  - increased minimum required version of Sub::Name.

2.1905   2017-01-07 (TRIAL RELEASE)


  - Added support for __no_BUILD__ as a constructor argument to skip calling
    any BUILD subs (used internally by modules like Moo that have their own
    implementation of calling BUILD) (PR#142, Graham Knop)

2.1904   2016-12-22 (TRIAL RELEASE)


  - Slight tweaks to the syntax used for hashes in a few tests, that were
    broken by a recent Test::More release that started using a new namespace
    that clashes with a (bareword) type name in these tests. (PR#141,

2.1903   2016-11-22 (TRIAL RELEASE)


  - When an attribute defines two methods (say a reader and writer) with the
    same name, this now generates a warning.

  - The warning when attribute methods overwrite one another is now much more
    informative. It includes the type of accessors involved (reader, writer,
    predicate, etc.) as well as the file and line where each accessor was
    defined. Fixes RT #118325.


  - Brought back the Moose::Meta::Method::Delegation->_get_delegate_accessor
    method for the benefit of MooseX::CurriedDelegation.

  - The definition context (package, file, & line) for attributes on
    Class::MOP and Moose metaclasses was wrong in all cases.

2.1902   2016-10-23 (TRIAL RELEASE)


  - The stack trace for an inlined delegation now tells you where the
    delegating attribute was declared (file and line number).

2.1901   2016-10-20 (TRIAL RELEASE)


  - warnings are only checked for in tests under AUTHOR_TESTING, so as to not
    prevent installation when warnings occur in prerequisites.

2.1900   2016-10-09 (TRIAL RELEASE)


  - Most delegations are inlined now. This is not done for speed but rather to
    improve stack traces when the delegated-to method throws an exception or
    when the delegated-to method simply does not exist in the
    delegatee. Previously, this stack trace and associated error were less
    helpful than they could have been. Requested by Tim Bunce, Olaf Alders,
    and Van de Bugger. (RT#46614, RT#98402, and RT#109631).

2.1807   2016-12-22


  - The definition context (package, file, & line) for attributes on
    Class::MOP and Moose metaclasses was wrong in all cases.

  - Slight tweaks to the syntax used for hashes in a few tests, that were
    broken by a recent Test::More release that started using a new namespace
    that clashes with a (bareword) type name in these tests. (PR#141,

2.1806   2016-09-25


  - A role generated on the fly (as opposed to one in a file on disk) could
    not be used as a trait. Fixed by Aaron Cohen. (RT#92089, PR#47).


  - When a required attribute's init_arg differs from the attribute's name, we
    now include both the attribute name and init_arg in the exception thrown
    when that attribute is not provided. (RT#116814, Gordon Fisher)

  - The unimport sub generated by Moose::Exporter can now be called with
    parameters like { into => 'Package' } or { into_level => 1 }, just like
    the import sub it generates. Requested by Dmytro Zagashev. (RT #93666).

  - Moose::Meta::Attribute objects created from role attributes keep a
    reference to the Moose::Meta::Role::Attribute which created
    them. Moose::Meta::Attribute now has ->role_attribute and
    ->has_role_attribute methods. RT #84563 and #117586. (Dave Rolsky)


  - Updated Moose::Manual::Roles with more detail on role consumption and how
    to deal with various corner cases involving required methods, multiple
    roles, etc.

2.1805   2016-08-19


  - remove inc/ that should not have appeared in the distribution (an
    issue since 2.1800; RT#117071)

2.1804   2016-06-02


  - restrict Type::Tiny test to versions new enough to support native traits.

  - restrict recipe test to perls where Regexp::Common is installable

2.1803   2016-05-31


  - fixed type compatibility with Type::Tiny that was partially lost in

2.1802   2016-05-25


  - Fixed test failures if Specio 0.14+ was installed.


  - updated metadata, used by moose-outdated and t/zzz-check-breaks.t,
    to reflect downstream modules affected by the recent removal of

2.1801   2016-05-02


  - bundled an updated ExtUtils::HasCompiler, to support building with a
    noexec $TMPDIR.

2.1800   2016-04-30


  - an increased Data::OptList version has been added to recommended prereqs,
    for greater speed. (Olivier Mengué, PR#123)

2.1705   2016-04-21 (TRIAL RELEASE)


  - build-time compiler sanity checking is now done with ExtUtils::HasCompiler
    instead of ExtUtils::CBuilder.

2.1704   2016-04-13 (TRIAL RELEASE)


  - Fixed method cache regeneration when a class contains a blessed sub
    (RT#113704, Graham Knop, PR#122)


  - restore test on perl 5.8.x when Class::C3::XS is not installed (RT#113704)

2.1703   2016-04-12 (TRIAL RELEASE)


  - skip dysfunctional test on perl 5.8.x when Class::C3::XS is not installed

2.1702   2016-04-08 (TRIAL RELEASE)


  - Moose::Meta::Attribute::Native::Trait::Array now documents the return
    value for 'first_index' when there is no match (-1).


  - Moose::Exception's message attribute can now be any defined value, so as
    to allow for objects with a stringification overload in place of a string.

2.1701   2016-04-07 (TRIAL RELEASE)


  - Fixed the last remaining use of List::MoreUtils (RT#113587)

2.1700   2016-04-06 (TRIAL RELEASE)


  - Moose::Exception now has a boolean overload. (Graham Knop, PR#119)

  - All uses of List::MoreUtils have been removed, replaced by inlined forms
    or equivalents in List::Util. (Graham Knop, PR#120)

2.1605   2016-02-16


  - Fixed references to test files that were renamed when their associated
    documentation files were renamed in 2.0500 (RT#111898)

  - Moose::Manual::Roles now contains a section on handling required
    attributes in role application (thanks, Kent Fredric!)

  - a few other, very minor, documentation fixes

2.1604   2015-11-07


  - The minimum perl requirement is now set in configure-requires, as well as
    runtime-requires, to ensure that smokers bail out early enough to declare
    the installation as a N/A rather than a FAIL.

2.1603   2015-08-28

  - No changes from 2.1602-TRIAL (other than a minor documentation tweak).

2.1602   2015-08-14 (TRIAL RELEASE)


  - Replaced uses of overload::Overloaded with the new
    Devel::OverloadInfo::is_overloaded (thanks, ilmari!) to work around more
    issues with overload handling in older versions of perl.

2.1601   2015-08-10 (TRIAL RELEASE)


  - Explicit boolean overload handling has been added to Class::MOP::Method
    and Moose::Meta::Role::Method::Required, to work around a bug with the
    handling of overload fallbacks on perl 5.8.x.  In particular this fixes
    issues observed in MooseX::MethodAttributes.

2.1600   2015-07-31


  - Made all docs use =head2 and =head3 for methods/functions so that they
    appear as part of the table of contents on MetaCPAN.

2.1501   2015-07-20 (TRIAL RELEASE)


  - Added a new slideshow by Shawn M. Moore (sartak) to
  - Documentation for exception classes has been rewritten, with
    Moose::Manual::Exceptions::Manifest changing how it describes each class's
    attributes and methods. (Dave Rolsky, PR#95)


  - The change in 2.1500 to allow DOES to check delegated options has been
    reverted. This turned out to have a variety of issues both in concept and
    implementation; it will be refined further in MooseX::Does::Delegated.


  - The name for an anonymous sub that is used in method modifiers (that shows
    up in stack traces etc) now identifies the package and method being
    modified. (Philipp Gortan, PR#94)

2.1500   2015-07-01 (TRIAL RELEASE)


  - An object's DOES method now also checks roles composed by delegated
    objects (Chris Prather, PR#104)

2.1405   2015-06-06


  - The native 'Array' trait 'sort' accessor now returns the number of
    elements in scalar context, instead of the undefined value (or a
    different, seemingly-random, value under 5.23.x).

2.1404   2015-04-17


  - Add Sub::Identify to prereqs. (RT #101661)
  - bump List::Util prereq to avoid a memory leak (RT#101124)


  - Added section to Moose::Manual::Resources to list external links related
    to Moose (RT #101993, Michael LaGrasta)

2.1403   2014-12-07


  - Added a section to Moose::Manual::MethodModifiers illustrating how method
    modifiers work with inheritance. (Andreas Koenig, RT #98940)
  - Added docs to on the -meta_name import option. This addresses RT


  - Fix a test that fails on MSWin32 systems using nmake
  - fix dev build compilation error when using MSVC (A. Sinan Unur)


  - the modules in the git repository now have a defined $VERSION, to make it
    easier to test MooseX::* and other code under development.

2.1402   2014-11-05


  - Fix a test that was trying to load Test::Exception instead of Test::Fatal.
    (Michael Schout)

2.1401   2014-11-03


  - The core overloading support interacted badly with
    MooseX::MarkAsMethods. If you used MooseX::MarkAsMethods in a role that
    provided overloading, then that overloading would not be properly applied
    to consuming classes, leading to very weird errors of the form:

        Can't resolve method "???" overloading """" in package "Class2" ...

    Note that the problems that MooseX::MarkAsMethods fixes are no longer
    present if you are using Moose 2.1400+ and namespace::autoclean 0.16+. We
    encourage you to upgrade both of these modules and remove
    MooseX::MarkAsMethods from your code base.

2.1400   2014-11-01


  - Moose exception classes now stringify all stack frames, to avoid issues
    in global destruction (see RT#99811)

2.1307   2014-10-26 (TRIAL RELEASE)


  - Support added to Moose::Exporter for exporting subs by their fully
    qualified name, as well as coderefs. This avoids internal breakage if some
    other module has monkey-patched a sub to be exported and left it anonymous
    (e.g. RT#88669). (Graham Knop, PR#84)


  - Further refined the overloading fixes from 2.1306, fixing fallback
    handling on older perl versions (Dave Rolsky, PR#85)

2.1306   2014-10-25 (TRIAL RELEASE)


  - Rewrote overloading implementation to use a new Class::MOP::Overload
    object. This object properly captures all overloading information. The
    Class::MOP::Method::Overload class has been removed. (Dave Rolsky, PR#83)


  - If a role had method-based overloading but did not actually implement the
    specified method, its overloading was simply ignored when applying
    overloading to other roles or classes. Reported by rjbs. RT #98531.

2.1305   2014-10-23 (TRIAL RELEASE)


  - By default, exceptions thrown from inside Moose now remove most of the
    Moose internals from their stack trace when stringifying. This makes for
    much more readable error messages in most cases. Set the
    MOOSE_FULL_EXCEPTION env var to true to get the complete stack trace.

2.1304   2014-09-25 (TRIAL RELEASE)


   - closed a memory leak in Moose exception objects where captured stack
     trace frames would contain circular references to the exception objects
     themselves (Graham Knop, PR#81)

2.1303   2014-09-20 (TRIAL RELEASE)


  - fix tests that fail on altered warning messages in perl 5.21.4 (RT#98987)

2.1302   2014-08-20 (TRIAL RELEASE)


  - When a role consumes another role and they differ in their overloading
    fallback settings, the consuming role now silently wins instead of
    throwing an exception. This is consistent with how other
    role-consumes-role conflicts are handled.
  - Fixed the docs for overloading conflicts to match reality.

2.1301   2014-08-19 (TRIAL RELEASE)


  - Conflict detection for overloading operators is now more correct. If a
    class consumed two roles that both had identical overloading methods
    (because they got them from some other role, for example), this caused an
    error, but it shouldn't. GH #4. (rjbs)
  - Similarly, when a role consumes another role, conflicts in overloading
    operators are now silently resolved in favor of the consuming role, just
    as they are with methods. Note that conflicts between the fallback setting
    for roles are still an error.

2.1300   2014-08-11 (TRIAL RELEASE)


  - Moose now has core support for overloading in roles. When a role with
    overloading is applied to classes or other roles, the overloading settings
    are transferred to the consumer. Conflicts between roles are treated much
    like method conflicts. This obviates the need for
    MooseX::Role::WithOverloading. If you are using
    MooseX::Role::WithOverloading, upgrade to version 0.15+ and it will simply
    become a no-op when used with this version of Moose.


  - The overloading info methods for roles and classes no longer treat
    "fallback" as an overloaded op. Instead, there are new
    get_overload_fallback_value() and set_overload_fallback_value() methods to
    deal with this explicitly. This is arguably a bug fix.

2.1213   2014-09-25


   - closed a memory leak in Moose exception objects where captured stack
     trace frames would contain circular references to the exception objects
     themselves (Graham Knop, PR#81)

2.1212   2014-09-19


  - fix tests that fail on altered warning messages in perl 5.21.4 (RT#98987)

2.1211   2014-08-12


  - Updated Changes and Moose::Manual::Delta to note when we started removing
    lazy_build from docs. Also added a note in the Moose::Meta::Attribute docs
    stating that use of this feature is discouraged.
  - Added a pointer from the auto_deref feature to
    Moose::Meta::Attribute::Native. This is often a better choice.


  - The subs installed by Moose::Exporter->setup_import_methods are now named
    using Sub::Name (Dave Rolsky, RT#97572)

2.1210   2014-07-03


  - Clarify that Moose::Exception exists for internal usage and that user
    code is better off using the Throwable role or Throwable::Error superclass.
  - Moose::Manual::Support policy clarified regarding legacy Perl versions


  - logic has been removed for an alpha branch of Test::Builder that will
    never see the light of day, and will break with upcoming Test::Builder
    changes (Exodist)

2.1209   2014-06-05


  - The is_anon method now always returns false when called on
    Moose::Meta::Role::Composite objects. This isn't strictly right, but for
    the purposes of Moose internals, where "is_anon" really means "needs to be
    cleaned up", it's correct. This fixes warnings that were seen when using
    recent Moose (2.1100+) and MooseX::Role::Parameterized roles as part of a
    composite role. These warnings only appear with Perl 5.16 and earlier.

2.1208   2014-06-01


  - fix implementation of throw_exception in internal Class::MOP traits,
    caused by changes in 2.1207 (ether, RT#96112)

2.1207   2014-05-26


  - Fixed Specio support to work with the latest Specio (0.10). This version of
    Specio no longer uses Moose internally.
  - exceptions in Class::MOP no longer use Moose::Util, instead using their
    own private implementation of throw_exception, to avoid needless premature
    loading of Moose logic.

2.1206   2014-05-14


  - exceptions should not throw other exceptions; fixes cases where exceptions
    were reporting the wrong error (Upasana, RT#92818 and RT#94795)


  - prereqs needed strictly for building with Dist::Zilla have been moved from
    develop requires to develop recommends, to simplify automated testing on
    older perls that cannot install all Dist::Zilla components
  - removed instances of metaobjects in exception classes where they're not
    really required

2.1205   2014-04-16


  - new utility interface: Moose::Util::is_role


  - better error message provided when trying to load a trait class that does
    not exist in @INC (Upasana, RT#94731)


  - new test added, to run last, which runs `moose-outdated` as a possibly
    more visible mechanism to provide important information to the user
    (re RT#92780)

2.1204   2014-02-07


  - bump minimum prereq needed for optional test using MooseX::NonMoose (which
    broke with new Module::Runtime, see 2.1203), so users can install Moose
    and pass tests before updating MooseX::NonMoose.

2.1203   2014-02-07


  - bump prereq on Module::Runtime to properly detect when a module fails to
    load, and fix how we call these subs (Zefram, RT#92770, RT#86394, RT#92791)


 - line numbers in shipped code are now almost the same (within 3) as the
   repository source, for easier debugging

2.1202   2014-01-20


  - string comparisons are now possible with Moose exceptions (RT#92232)

2.1201   2014-01-11


  - re-release to index pod files (Moose::Cookbook::*, Moose::Manual::* etc).

2.1200   2014-01-06


  - Releasing 2.1108 as stable (last stable release was 2.1005).

2.1108   2014-01-05 (TRIAL RELEASE)


    - fixed distribution manifest
    - minor documentation and metadata updates

2.1107   2013-11-29 (TRIAL RELEASE)


  - many additions to the list of conflicting modules (those that require
    updates after installing Moose), reflecting recent API changes
  - now failing early at build time, with a useful error message, if a
    compiler is not available

2.1106   2013-11-05 (TRIAL RELEASE)


  - throw_error import cleaned from Moose::Object after use (doy)
  - resolved new circular load issue between Moose::Util and Class::MOP (Kent
    Fredric, RT#89713 and PR#42)

2.1105   2013-10-31 (TRIAL RELEASE)


  - legacy throw_error now takes multiple arguments, like confess does
    (Karen Etheridge)

2.1104   2013-10-30 (TRIAL RELEASE)


  - Class::MOP::Object::_inline_throw_error is back, used by some MooseX
    modules (Upasana)

2.1103   2013-10-26 (TRIAL RELEASE)


  - fix errors in last trial release relating to Moose::Error::Default,
    Moose::Util::throw_error (Upasana)

2.1102   2013-10-20 (TRIAL RELEASE)


  - die if a role to consume can't be found -- this restores behaviour as in
    2.1005 (doy)
  - fix test to accomodate Devel::PartialDump possibly not being installed

2.1101   2013-10-20 (TRIAL RELEASE)


  - Moose string exceptions have been replaced by Moose::Exception objects. See
    Moose::Manual::Delta for details.

2.1100   2013-09-07 (TRIAL RELEASE)


  - Class::MOP::load_class, Class::MOP::is_class_loaded, and
    Class::MOP::load_first_existing_class are now deprecated. See
    Moose::Manual::Delta for details.

  - The non-arrayref forms of enum and duck_type have been deprecated. See
    Moose::Manual::Delta for details.

  - Many deprecated features have now been removed:
    - optimize_as for type constraints
    - the "default is" and "default default" features for native delegations
    - setting coerce => 1 on an attribute whose type constraint has no coercion
    - the public version of Moose::Meta::Method::Destructor::initialize_body


  - Creating classes with Moose now always sets the appropriate entry in %INC,
    even if it wasn't loaded from a file. This should make writing classes
    inline easier, and will allow us to be more intelligent about figuring out
    when classes are loaded in the future. See Moose::Manual::Delta for more
    details. Note that this is slightly backwards-incompatible in some edge

  - Moose now uses Module::Runtime instead of Class::Load to load classes. This
    means that there are no more issues with the weird heuristics that
    Class::Load does to determine if a class was previously loaded (inheriting
    from an empty package is now possible, for instance). See
    Moose::Manual::Delta for more details. This is also slightly
    backwards-incompatible in some edge cases.

2.1005   2013-08-07


  - add_method now accepts blessed subs (Graham Knop, PR#28)


  - If a role consumed another role, we resolve method conflicts just like a
    class consuming a role, but when metaclass compat tried to fix up
    metaclass roles, we were putting all methods into one composite role and
    allowing methods in the metaclass roles to conflict. Now we resolve them
    as we should. (Jesse Luehrs, PR#27)

  - Some edge cases in tests with and non-existent module files are
    handled more strictly (see also perl RT#118561) (Graham Knop, PR#25)

2.1004   2013-07-26


  - 2.1003 was released with some bad metadata, which caused the prereq test
    to fail.

2.1003   2013-07-26


  - Releasing 2.0901 as stable.

2.0901   2013-06-21 (TRIAL RELEASE)


  - The with_immutable() sub from Test::Moose now passes a boolean value to
    the code block containing tests indicating whether or not the classes have
    been made immutable. This can make for nicer test descriptions. (Dave

  - You can now use Specio types instead of Moose builtins or
    MooseX::Types. However, this support is still experimental (as is Specio),
    so use it with care. (Dave Rolsky)

2.0900   2013-05-27 (TRIAL RELEASE)


  - Fixed the Num builtin type to reject NaN, Inf, numbers with whitespace,
    and other questionable strings. The MooseX::Types::LaxNum distribution
    implements the old behavior. RT#70539 (Upasana)

2.0802   2013-05-07


  - fix incompatibilities with Test::Builder 1.005+ (Karen Etheridge)
  - Moose::Manual::Contributing updated to reflect the change of primary
    repository from to

2.0801   2013-03-28


  - properly apply traits at compile time (error introduced in 2.0800,
    RT#77974). (doy)

2.0800   2013-03-28


  - The super() subroutine now carps if you pass it arguments. These arguments
    are always ignored, but we used to ignore them silently. RT #77383.

  - Roles can now override methods from other roles they consume directly,
    without needing to manually exclude them (just like classes can). (mst)


  - Fix false positive when checking for circular references for modules that
    use the "also" parameter with Moose::Exporter. Reported by Jon
    Swartz. Fixed by Matthew Wickline. RT #63818.

  - Fix memory leak in type unions. (Karen Etheridge) RT#83929.

  - Fix application of traits at compile time. (doy) RT#77974.

2.0604   2012-09-19


  - Fix nonsensical error message for inlined accessors of required attributes.

  - Stop trying to localize a lexical (blead now throws an error for this). RT
    #79257, perl #114628. (sprout)


  - Depend on a version of Carp new enough to have caller_info. RT #79367.

2.0603   2012-06-28


  - Fix test failure in blead. RT #78085.

2.0602   2012-05-07


  - Ensure that the Moose::Exporter-generated init_meta returns the same value
    that it did previously. This isn't really a bug, since the return value has
    never been tested or documented, but since the generated init_meta is
    nothing more than a compatibility shim at this point, there's no reason to
    not make it as compatible as possible. Reported by Moritz Onken. (doy)


  - The lazy_build attribute feature was removed from

2.0601   2012-05-01


  - Fix init_meta order when multiple also packages are specified (this matters
    when one of them is being used to actually initalize the metaclass,
    typically with also => 'Moose'). Reported by Randy Stauner. (doy)

2.0600   2012-04-29


  - Releasing 2.0502 as stable.

2.0502   2012-04-25 (TRIAL RELEASE)


  - The Test::DependentModules test now covers a much wider range of downstream
    dependents (all of them in fact, for some definition of "all"). This should
    allow us to track inadvertent backwards compatibility breakages much more
    effectively. (doy)

  - A few test tweaks to avoid spurious failures. (doy)

2.0501   2012-04-03 (TRIAL RELEASE)


  - Avoid syntax errors on pre-5.14. (doy)

2.0500   2012-04-03 (TRIAL RELEASE)


  - Class::MOP::Class now has methods for introspecting and modifying the
    overloaded operators for a class. (doy)


  - The cookbook recipes have all been renamed. Instead of numbered recipes
    (Basics::Recipe1), we now have descriptive names
    (Basics::Point_AttributesAndSubclassing). This makes it easier for us to
    add and remove recipes in the future, and makes it a little easier to
    converse about them, since the name gives us some clue of what they


  - Re-declaring a class_type or role_type constraint that has already been
    declared now just returns the original type constraint, rather than
    replacing the original constraint and ergo losing any coercions that were
    on the original constraint. Fixes RT #73289. (t0m)

  - Moose::Exporter now calls init_meta methods in the correct order, when
    multiple levels of 'also' parameters are specified. Reported by Rocco
    Caputo. (doy, perigrin)

  - Moose::Exporter no longer generates init_meta methods in order to apply
    metaroles, since the metaclass itself isn't guaranteed to exist yet at that
    point. Metaroles are now applied at the end of import, after all
    user-defined init_meta methods have been called. Fixes RT #51561. (doy)

  - Fixed a memory leak. This occurred when creating an anonymous
    class. Immutabilizing an anonymous class still leaks memory due to a bug in
    Eval::Closure (which should hopefully be fixed soon). Based on code and bug
    report from Carlos Lima. RT #74650.

  - Fix a segfault when adding a method to a class which was defined in a
    package which was deleted. (doy)

2.0403   2012-04-03


  - No changes, reupload to fix indexing.

2.0402   2012-02-04


  - Minor documentation fixes.

  - Fix test failure on blead (test was unnecessarily strict). Reported by
    Nicholas Clark. (doy)

2.0401   2011-11-17


  - Attributes with weak_ref now weaken their associated slot when they are
    initialized through a lazy default or builder. Reported by tome. (doy)

2.0400   2011-11-15


  - No changes from 2.0302 (other than a few minor documentation tweaks).

2.0302   2011-11-02 (TRIAL RELEASE)


  - Fix test failure on 5.8. (Dave Rolsky)

  - Make make_immutable return value consistent and document it to be true.

2.0301   2011-10-21 (TRIAL RELEASE)


  - Fix compilation on 5.8. Reported by ether. (doy)

  - A custom error class caused a warning when the class that used it was made
    immutable. Reported by Maroš Kollár. RT #71514. (Dave Rolsky)


  - The enum type will now allow single value enumerations. Previously, two or
    more values were required. (rjbs)

2.0300   2011-09-23 (TRIAL RELEASE)


  - The optimize_as option for type constraints has been deprecated. Use the
    inline_as option to provide inlining code instead. (Dave Rolsky)


  - Methods to introspect a class's methods will now return methods defined in
    UNIVERSAL (isa, can, etc.). This also means that you can wrap these
    methods with method modifiers. RT #69839. Reported by Vyacheslav
    Matyukhin. (Dave Rolsky)

  - The ->parent and ->parents method for a union now return the nearest
    common ancestor of that union's component types. See Moose::Manual::Delta
    for more details. (Dave Rolsky)

  - The ->parents method used to return an arrayref for union types, and a
    list of one or more types for all other types. Now they all return
    lists. (Dave Rolsky)

  - The ->is_subtype_of and ->is_a_type_of methods have changed their behavior
    for union types. Previously, they returned true if any of their member
    types returned true for a given type. Now, all of the member types must
    return true. RT #67731. (Dave Rolsky)


  - The Moose::Exporter module now has a "meta_lookup" option when creating an
    importer. This allows you to specify an alternate method for determining
    the metaclass of a caller. This is useful for modules like
    MooseX::Role::Parameterized which generate new metaclasses on the
    fly. (sartak)

  - Added a Moose::Meta::Method->is_stub method. (Dave Rolsky)


  - A subtype of a union type did not return the right results when you called
    ->is_subtype_of or ->is_a_type_of on it. This has been fixed. RT
    #70322. (Dave Rolsky)

  - An attribute accessor or delegation method can overwrite a stub method and
    this will no longer throw an error. Reported by Mark-Jason Dominus. RT
    #69988. (Dave Rolsky)

  - The error generated by unfulfilled method requirements during role
    composition now mentions how to work around imported methods not being
    recognized. Reported by Michael Schwern. RT #60583. (doy)

  - class_type and role_type will now throw errors if you attempt to use them
    to override existing types, just like type and subtype have always done.

  - Implicitly creating class or role types by using them as the 'isa' or
    'does' parameter to attribute construction will now register the type. This
    means that it cannot later be redefined as something else. (doy)

  - $class_type->is_subtype_of no longer returns true if passed the name of the
    class that the class type represents when the class type wasn't registered.

  - Removing anonymous metaclasses prematurely no longer prevents reaping of
    the associated stash. (doy)


  - The Class::MOP::load_class and Class::MOP::is_class_loaded subroutines are
    no longer documented, and will cause a deprecation warning in the
    future. Moose now uses Class::Load to provide this functionality, and you
    should as well. (Dave Rolsky)

2.0205   2011-09-06


  - The Array and Hash native traits now provide a "shallow_clone" method,
    which will return a reference to a new container with the same contents as
    the attribute's reference.


  - Specifying an invalid value in a hashref 'handles' value now throws a
    sensible error. Reported by Mark-Jason Dominus. RT #69990. (Dave


  - When specifying an attribute trait, passing options for the trait besides
    -alias or -excludes caused a warning. However, passing other options is
    totally valid when using MooseX::Role::Parameterized. Fixes RT
    #70419. (sartak)

  - Allow regexp objects in duck_type constraints (to bring this in line with
    the Object constraint).

2.0204   2011-08-25


  - Validating duck_type type constraint turned out to work only by accident,
    and only when not running under the debugger. This has been fixed.
    (Florian Ragwitz)


  - Loosen the dependency on ExtUtils::ParseXS.

2.0203   2011-08-23


  - is_class_loaded now properly detects packages which have a version object
    in their $VERSION.

  - Fix XS compilation under blead.

2.0202   2011-07-26


  - Be more consistent about how type constraint messages are handled.

2.0201   2011-07-22


  - Moose::Util::does_role shouldn't call ->does on things that don't inherit
    from Moose::Object.

  - Make ->does initialize the metaclass, so that calling it as a class method
    on a class which sets up inheritance via some method other than extends
    works properly (this fixes an issue with MooseX::Types).

  - Make Dist::CheckConflicts a runtime requirement, so moose-outdated always

2.0200   2011-07-18


  - No changes from 2.0105 (other than a few minor documentation tweaks).

2.0105   2011-06-27 (TRIAL RELEASE)


  - Moose::Util::does_role now respects overridden ->does methods. (doy)

2.0104   2011-06-20 (TRIAL RELEASE)


  - Include changes from 2.0010.

2.0103   2011-06-20 (TRIAL RELEASE)


  - Several things that have been deprecated for a while have been removed. See
    the 2.0000 section in Moose::Manual::Delta for details.


  - New Moose::Util::TypeConstraints::union function for creating union type
    constraints without having to rely on the string type constraint parsing.
    This also allows for creating unions of anonymous type constraints.


  - Include changes from Moose 2.0009.

2.0102   2011-06-18 (TRIAL RELEASE)


  - The native Array trait now has a 'first_index' method, which works just
    like the version in List::MoreUtils. (Karen Etheridge)

  - Clean up some internal code to help out extensions.


  - Include changes from Moose 2.0008.

2.0101   2011-06-06 (TRIAL RELEASE)


  - Various packaging issues.

2.0100   2011-06-06 (TRIAL RELEASE)


  - Using a hand-optimized type constraint is now deprecated. In keeping with
    our release policy, this won't actually start warning until the 2.0200


  - Type constraints can now provide inlined versions, which should make
    inlined code which uses type constraints (such as accessors) faster. This
    replaces the existing hand-optimized constraint feature.  (Dave Rolsky)


  - Remove a lot of cases where generated methods closed over meta objects.
    Most simple cases should now only close over simple data types and
    coderefs. This should make deparsing simpler.

2.0010   2011-06-20


  - Fix regression in 2.0009 and 2.0103 when applying roles during init_meta in
    an exporter that also re-exports Moose or Moose::Role. (t0m, ilmari)

2.0009   2011-06-19


  - duck_type type constraints now report reasonable errors when given
    something which isn't an instance of an object. (t0m)

  - Moose::Util::apply_all_roles now works even if the applicant is a non-Moose
    class. (perigrin)

  - When an object is reblessed, triggers are called on attributes that are
    set during the reblessing. (Karen Etheridge).


  - Better error message if Moose->init_meta is called with a 'metaclass'
    option when that metaclass hasn't been loaded. (jasonmay)

2.0008   2011-06-16


  - The 'accessor' native delegation for hashrefs now allows setting the value
    to undef. (sugoik, doy)


  - Various generated methods have more useful context information. (doy)

2.0007   2011-05-15


  - Make sure weak attributes remain weak when cloning. (doy, rafl)

2.0006   2011-05-09


  - Revert the List::MoreUtils version bump, as it breaks backwards
    compatibility. The dependency will be bumped with Moose 2.0200.

2.0005   2011-05-09


  - Only sort the alias keys when determining caching.

2.0004   2011-05-09


  - Bump the List::MoreUtils dep to avoid buggy behavior in old versions.

  - Sort the list of roles and the alias and excludes parameters when
    determining caching, since their order doesn't matter.

2.0003   2011-05-09


  - Applying multiple role objects (rather than role names) at once no longer
    skips every other role. (rjbs)

  - Caching of anon classes now works more sanely in the presence of role
    application parameters - alias and excludes options are taken into account,
    and caching is disabled entirely if other parameters exist. Asking for
    caching (instead of just not weakening) when parameters are given will
    begin warning in Moose 2.0200. (doy, autarch)

2.0002   2011-04-28


  - Provide definition context information for constructors and destructors, so
    that they will show up as something other than "generated method (unknown
    origin)". Also, add the package that accessors are defined in to their
    definition context.

  - Use Devel::PartialDump in type constraint error messages, if it is


  - Stop hiding warnings produced by throwing errors in DEMOLISH methods.

  - The 'reset' native delegation for Counter attributes will now also respect
    builders (previously, it only respected defaults).

2.0001   2011-04-22


  - Anonymous classes and roles now have a unified implementation in
    Class::MOP::Package. This means that anonymous packages are now also
    possible. (Shawn M Moore, doy)


  - No longer call XSLoader from multiple places, as this causes issues on
    older perls. (doy, ribasushi)

  - Moose::Meta::Role->create now accepts the 'roles' parameter, as it was
    documented to. (Chris Weyl)

  - Depend on Eval::Closure 0.04, which fixes some issues in mod_perl
    environments. (doy, mateu)

2.0000   2011-04-11


  - The RegexpRef type constraint now accepts regular expressions blessed into
    other classes, such as those found in pluggable regexp engines.
    Additionally the 'Object' constraint no longer rejects objects implemented
    as a blessed regular expression. (David Leadbeater)


  - The lazy_build attribute feature was mostly removed from the docs and is
    no longer encouraged.


  - Moose::Manual::Support now explicitly states when major releases are
    allowed to happen (January, April, July, or October).

1.9906   2011-04-04 (TRIAL RELEASE)


  - Update conflicts list.
  - Minor pod updates.

1.9905   2011-03-28 (TRIAL RELEASE)


  - The Moose::Meta::Role::Attribute class now has an original_role method
    which returns the role which first defined an attribute. See the docs for
    details. (Dave Rolsky)

  - Moose::Util::MetaRole will make sure that the class to which you're
    applying metaroles or base class roles can actually have them applied. If
    not (it's not a Moose class, it has a non-Moose metaclass, etc.), then it
    gives a useful error message. Previously, this would just end up dying in
    the MetaRole code without a useful message. (Dave Rolsky)


  - When a role had its own applied_attribute metaclass (usually from MetaRole
    application), that metaclass would get lost when that role participated in
    role composition. It was also lost if that role was consumed by some other
    role. Both of these cases have been fixed. Attributes are always applied
    with the applied_attribute metaclass of the role which originally defined
    them. (Dave Rolsky)

1.9904   2011-03-04 (TRIAL RELEASE)


  - Reinitializing anonymous roles used to accidentally clear out the role's
    stash in some circumstances. This is now fixed. (doy)

  - The Int type constraint now rejects integers with trailing newlines.
    (Matthew Horsfall)

1.9903   2011-02-28 (TRIAL RELEASE)


  - Reverse the order that Moose::Exporter 'also' exports are dispatched. When
    trying to re-export from a package that itself exported a modified set of
    Moose sugar, you'd get the original Moose sugar instead of the overrides.
    There are also now tests for this. (perigrin)

  - Don't initialize lazy attributes with defaults in the constructor (for
    immutable classes). (mo)

  - When reinitializing meta objects for classes and roles, we failed to
    preserve roles and role applications. This led to weird bugs. Many MooseX
    modules end up reinitializing your class or role. (Dave Rolsky)

1.9902   2011-01-03 (TRIAL RELEASE)


  - Fix generation of CCFLAGS.

  - Add a bit more Dist::Zilla functionality.

1.9901   2011-01-03 (TRIAL RELEASE)


  - Fix some indexing issues.

  - Fix a few issues with the conflict checking stuff.

1.9900   2011-01-01 (TRIAL RELEASE)


  - The entire Class::MOP distribution has been merged with Moose. In the
    future, the Class::MOP code itself will be merged into Moose, and
    eventually the Class::MOP namespace will disappear entirely. For the
    current release, we have simply changed how Class::MOP is
    distributed. (Dave Rolsky).

  - Switched to Dist::Zilla for development. However, we still have a minimal
    Makefile.PL in the repository that can be used for development. (Dave


  - Roles now have their own default attribute metaclass to use during
    application to a class, rather than just using the class's
    attribute_metaclass. This is also overridable via ::MetaRole, with the
    applied_attribute key in the role_metaroles hashref (doy).

  - The internal code used to generate inlined methods (accessor, constructor,
    etc.) has been massively rewritten. MooseX modules that do inlining will
    almost certainly need to be updated as well.


  - We now load the roles needed for native delegations only as needed. This
    speeds up the compilation time for Moose itself. (doy)

1.25   2011-04-01


  - Reinitializing anonymous roles used to accidentally clear out the role's
    stash in some circumstances. This is now fixed. (doy) (backported from

1.24   2011-02-22


  - Reverse the order that Moose::Exporter 'also' exports are dispatched. When
    trying to re-export from a package that itself exported a modified set of
    Moose sugar, you'd get the original Moose sugar instead of the overrides.
    There are also now tests for this. (perigrin) (backported from 1.9903)

1.23   2011-02-13


  - The 1.22 release had a bad MANIFEST. This has been fixed.

1.22   2011-02-13


  - When reinitializing meta objects for classes and roles, we failed to
    preserve roles and role applications. This led to weird bugs. Many MooseX
    modules end up reinitializing your class or role. (Dave Rolsky) (backported
    from 1.9903)

1.21   2010-11-24


  - The Support manual has been updated to reflect our new major/minor version
    policy. (Chris Prather)

  - The Contributing manual has been updated to reflect workflow changes based
    on this new support policy. (doy)


  - The role attribute metaclass did not inherit from Class::MOP::Object,
    which could cause errors when trying to resolve metaclass compatibility
    issues. Reported by Daniel Ruoso. (doy)

  - The lazy_build feature was accidentally removed from all the docs. Now
    it's listed in again. (Chris Prather)

1.20   2010-11-19


  - When using native delegations, if an array or hash ref member failed a
    type constraint check, Moose ended up erroring out with "Can't call method
    "get_message" on unblessed reference" instead of generating a useful error
    based on the failed type constraint. Reported by t0m. RT #63113. (Dave

1.19   2010-11-02


  - There was still one place in the code trying to load Test::Exception
    instead of Test::Fatal. (Karen Etheridge)

1.18   2010-10-31


  - Type constraint objects now have an assert_coerce method which will either
    return a valid value or throw an error. (rjbs)

  - We now warn when an accessor for one attribute overwrites an accessor for
    another attribute. RT #57510. (Dave Rolsky)


  - The native Array and Hash delegation methods now coerce individual new
    members if the _member type_ has a coercion. In other words, if the array
    reference is defined as an ArrayRef[DateTime], and you've defined a
    coercion from Int to DateTime, then pushing an integer via a delegation
    method will coerce the integer to a DateTime object. Reported by Karen
    Etheridge. RT #62351. (Dave Rolsky)

  - An attribute using native delegations did not always properly coerce and
    type check a lazily set default value. (doy and Dave Rolsky)

  - Using a regexp to define delegations for a class which was not yet loaded
    did not actually work, but did not explicitly fail. However, it caused an
    error when the class was loaded later. Reported by Max Kanat-Alexander. RT
    #60596. (Dave Rolsky)

  - Attempting to delegate to a class or role which is not yet loaded will now
    throw an explicit error. (Dave Rolsky)

  - Attempting to set lazy_build in an inherited attribute was ignored. RT
    #62057. (perigrin)


  - The Moose test suite now uses Test::Fatal instead of
    Test::Exception. (rjbs)

1.17   2010-10-19


  - Make native delegation inlining work with instance metaclasses where slot
    access is an do {} block, like Kioku. This fixes the use of native
    delegations together with Kioku. (Scott, doy)

1.16   2010-10-18


  - Almost every native delegation method which changes the attribute value
    now has an explicitly documented return value. In general, this return
    value matches what Perl would return for the same operation. (Dave Rolsky)

  - Lots of work on native delegation documentation, including documenting
    what arguments each native delegation method allows or requires. (Dave

  - Passing an odd number of args to ->new() now gives a more useful warning
    than Perl's builtin warning. Suggested by Sir Robert Burbridge. (Dave

  - Allow disabling stack traces by setting an environment variable. See
    Moose::Error::Default for details. This feature is considered
    experimental, and may change in a future release. (Marcus Ramberg)

  - The deprecation warning for using alias and excludes without a leading
    dash now tells you the role being applied and what it was being applied
    to. (mst).


  - A number of native trait methods which expected strings as arguments did
    not allow the empty string. This included Array->join, String->match,
    String->replace, and String->substr. Reported by Whitney Jackson. RT
    #61962. (Dave Rolsky)

  - 'no Moose' no longer inadvertently removes imports it didn't create
    itself. RT #60013. (Florian Ragwitz, doy)

  - Roles now support passing an array reference of method names to method
    modifier sugar functions. (doy)

  - Native traits no longer use optimized inlining routines if the instance
    requests it (in particular, if inline_get_slot_value doesn't return
    something that can be assigned to). This should fix issues with
    KiokuDB::Class. (doy)

  - We now ignore all Class::MOP and Moose classes when determining what
    package called a deprecated feature. This should make the deprecation
    warnings saner, and make it possible to turn them off more easily. (Dave

  - The deprecated "default is" warning no longer happens if the attribute has
    any accessor method defined (accessor, reader, writer). Also, this warning
    only happens when a method that was generated because of the "default is"
    gets called, rather than when the attribute is defined. (Dave Rolsky)

  - The "default default" code for some native delegations no longer issues a
    deprecation warning when the attribute is required or has a builder. (Dave

  - Setting a "default default" caused a fatal error if you used the builder
    or lazy_build options for the attribute. Reported by Kent Fredric. RT
    #59613. (Dave Rolsky)

1.15   2010-10-05


  - Major changes to Native Traits, most of which make them act more like
    "normal" attributes. This should be mostly compatible with existing code,
    but see Moose::Manual::Delta for details.

  - A few native traits (String, Counter, Bool) provide default values of "is"
    and "default" when you created an attribute. Allowing them to provide
    these values is now deprecated. Supply the value yourself when creating
    the attribute.

  - New option 'trait_aliases' for Moose::Exporter, which will allow you to
    generate non-global aliases for your traits (and allow your users to
    rename the aliases, etc). (doy)

  - 'use Moose' and 'use Moose::Role' now accept a '-meta_name' option, to
    determine which name to install the 'meta' name under. Passing 'undef'
    to this option will suppress generation of the meta method entirely. (doy)

  - Moose now warns if it overwrites an existing method named "meta" in your
    class when you "use Moose". (doy)


  - Native Trait delegations are now all generated as inline code. This should
    be much faster than the previous method of delegation. In the best case,
    native trait methods will be very highly optimized.

  - Reinitializing a metaclass no longer removes the existing method and
    attribute objects (it instead fixes them so they are correct for the
    reinitialized metaclass). This should make the order of loading many
    MooseX modules less of an issue. (doy)

  - The Moose::Manual docs have been revised and updated. (Dave Rolsky)


  - If an attribute was weak, setting it to a non-ref value after the object
    was constructed caused an error. Now we only call weaken when the new
    value is a reference.

  - t/040_type_constraints/036_match_type_operator.t failed on 5.13.5+. Fixed
    based on a patch from Andreas Koenig.

1.14   2010-09-21


  - Work around what looks like a bug in List::MoreUtils::any. This bug caused
    a weird error when defining the same union type twice, but only when using
    MooseX::Types. Reported by Curtis Jewell. RT #61001. (Dave Rolsky)

1.13   2010-09-13


  - The deprecation warnings for alias and excludes are back, use -alias and
    -excludes instead. (Dave Rolsky)


  - When composing one role into another and there is an attribute conflict,
    the error message now includes the attribute name. Reported by Sam
    Graham. RT #59985. (Dave Rolsky)

  - When a class is made immutable, the does_role method is overridden with a
    much faster version that simply looks role names up in a hash. Code which
    uses lots of role-based type constraints should be faster. (Dave Rolsky)

1.12   2010-08-28


  - Fix the MANIFEST. Fixes RT #60831, reported by Alberto Simões.

1.11   2010-08-27


  - An attribute in a subclass can now override the value of "is". (doy)

  - The deprecation warnings for alias and excludes have been turned back off
    for this release, to give other module authors a chance to tweak their
    code. (Dave Rolsky)


  - mro::get_linear_isa was being called as a function rather than a method,
    which caused problems with Perl 5.8.x. (t0m)

  - Union types always created a type constraint, even if their constituent
    constraints did not have any coercions. This bogus coercion always
    returned undef, which meant that a union which included Undef as a member
    always coerced bad values to undef. Reported by Eric Brine. RT
    #58411. (Dave Rolsky)

  - Union types with coercions would always fall back to coercing the value to
    undef (unintentionally). Now if all the coercions for a union type fail,
    the value returned by the coercion is the original value that we attempted
    to coerce. (Dave Rolsky).

1.10   2010-08-22


  - The long-deprecated alias and excludes options for role applications now
    issue a deprecation warning. Use -alias and -excludes instead. (Dave


  - Inlined code no longer stringifies numeric attribute defaults. (vg, doy)

  - default => undef now works properly. (doy)

  - Enum type constraints now throw errors if their values are nonsensical.


  - Optimizations that should help speed up compilation time (Dave Rolsky).

1.09   2010-07-25


  - You can no longer pass "coerce => 1" for an attribute unless its type
    constraint has a coercion defined. Doing so will issue a deprecation
    warning. (Dave Rolsky)

  - Previously, '+foo' only allowed a specific set of options to be
    overridden, which made it impossible to change attribute options related
    to extensions. Now we blacklist some options, and anything else is
    allowed. (doy, Tuomas Jormola)

  - Most features which have been declared deprecated now issue a warning using
    Moose::Deprecated. Warnings are issued once per calling package, not
    repeatedly. See Moose::Deprecated for information on how you can shut
    these warnings up entirely. Note that deprecated features will eventually
    be removed, so shutting up the warnings may not be the best idea. (Dave

  - Removed the long-deprecated Moose::Meta::Role->alias_method method. (Dave


  - We no longer unimport strict and warnings when Moose, Moose::Role, or
    Moose::Exporter are unimported. Doing this was broken if the user
    explicitly loaded strict and warnings themself, and the results could be
    generally surprising. We decided that it was best to err on the side of
    safety and leave these on. Reported by David Wheeler. RT #58310. (Dave

  - New with_traits helper function in Moose::Util. (doy)


  - Accessors will no longer be inlined if the instance metaclass isn't
    inlinable. (doy)

  - Use Perl 5.10's new recursive regex features, if possible, for the type
    constraint parser. (doy, nothingmuch)


  - Attributes now warn if their accessors overwrite a locally defined
    function (not just method). (doy)


  - Bump our required perl version to 5.8.3, since earlier versions fail tests
    and aren't easily installable/testable.

1.08   2010-06-15


  - Refactored a small amount of Moose::Meta::Method::Constructor to allow it
    to be overridden more easily (doy).

1.07   2010-06-05


  - Fixed a minor metaclass compatibility fixing bug dealing with immutable
    classes and non-class metaclass traits (doy, dougdude).

1.06   2010-06-01


  - Added '0+' overloading in Moose::Meta::TypeConstraint so that we can
    more uniformly compare type constraints between 'classic' Moose type
    constraints and MooseX::Types based type constraints.

1.05   2010-05-20


  - Packages and modules no longer have methods - this functionality was
    moved back up into Moose::Meta::Class and Moose::Meta::Role individually
    (through the Class::MOP::Mixin::HasMethods mixin) (doy).

  - BUILDALL is now called by Moose::Meta::Class::new_object, rather than by
    Moose::Object::new. (doy)


  - strict and warnings are now unimported when Moose, Moose::Role, or
    Moose::Exporter are unimported. (doy, Adam Kennedy)

  - Added a 'consumers' method to Moose::Meta::Role for finding all
    classes/roles which consume the given role. (doy)


  - Fix has '+attr' in Roles to explode immediately, rather than when the role
    is applied to a class (t0m).

  - Fix type constraint validation messages to not include the string 'failed'
    twice in the same sentence (Florian Ragwitz).

  - New type constraints will default to being unequal, rather than equal

  - The tests no longer check for perl's behavior of clobbering $@, which has
    been fixed in perl-5.13.1 (Florian Ragwitz).

  - Metaclass compatibility fixing has been completely rewritten, and should
    be much more robust. (doy)

1.04   2010-05-20

  - This release was broken and has been deleted from CPAN shortly after its

1.03   2010-05-06


  - Allow specifying required versions when setting superclasses or applying
    roles (Florian Ragwitz).

1.02   2010-05-01


  - Stop the natatime method provided by the native Array trait from returning
    an exhausted iterator when being called with a callback. (Florian Ragwitz)

  - Make Moose::Meta::TypeConstraint::Class correctly reject RegexpRefs.
    (Florian Ragwitz)

  - Calling is_subtype_of on a Moose::Meta::TypeConstraint::Class with itself or
    the class the TC represents as an argument incorrectly returned true. This
    behavior is correct for is_type_of, not is_subtype_of. (Guillermo Roditi)

  - Use File::Temp for temp files created during tests. Previously, files were
    written to the t/ dir, which could cause problems of the user running the
    tests did not have write access to that directory.. (Chris Weyl, Ævar
    Arnfjörð Bjarmason)

  - Pass role arguments along when applying roles to instances. (doy, lsm)

1.01   2010-03-26


  - The handles option now also accepts a role type constraint in addition to a
    plain role name. (Florian Ragwitz)


  - Record the Sartak/doy debt properly in Changes (perigrin)

1.00   2010-03-25


  - Moose::Meta::Attribute::Native::Trait::Code no longer creates reader
    methods by default. (Florian Ragwitz)


  - Improve various parts of the documentation and fix many typos.
    (Dave Rolsky, Mateu Hunter, Graham Knop, Robin V, Jay Hannah, Jesse Luehrs)


  - Paid the $10 debt to doy from 0.80   2009-06-06 (Sartak)

0.99   2010-03-08


  - New method find_type_for in Moose::Meta::TypeConstraint::Union, for finding
    which member of the union a given value validates for. (Cory Watson)


  - DEMOLISH methods in mutable subclasses of immutable classes are now called
    properly (Chia-liang Kao, Jesse Luehrs)


  - Added Moose::Manual::Support that defines the support, compatiblity, and
    release policies for Moose. (Chris Prather)

0.98   2010-02-10


  - An internals change in 0.97 broke role application to an instance in some
    cases. The bug occurred when two different roles were applied to different
    instances of the same class. (Rafael Kitover)

0.97   2010-02-09


  - Calling ->reinitialize on a cached anonymous class effectively uncached
    the metaclass object, causing the metaclass to go out of scope
    unexpectedly. This could easily happen at a distance by applying a
    metarole to an anonymous class. (Dave Rolsky).

0.96   2010-02-06


  - ScalarRef is now a parameterized type. You can now specify a type
    constraint for whatever the reference points to. (Closes RT#50857)
    (Michael G. Schwern, Florian Ragwitz)


  - ScalarRef now accepts references to other references. (Closes RT#50934)
    (Michael G. Schwern)

0.95   2010-02-04


  - Moose::Meta::Attribute::Native::Trait::Code now provides execute_method as
    a delegation option. This allows the code reference to be called as a
    method on the object. (Florian Ragwitz)


  - Moose::Object::does no longer checks the entire inheritance tree, since
    Moose::Meta::Class::does_role already does this. (doy)

  - Moose::Util::add_method_modifier (and subsequently the sugar functions
    Moose::before, Moose::after, and Moose::around) can now accept arrayrefs,
    with the same behavior as lists. Types other than arrayref and regexp
    result in an error.  (Dylan Hardison)

0.94   2010-01-18


  - Please see the changes listed for 0.93_01 and Moose::Manual::Delta.


  - Improved support for anonymous roles by changing various APIs to take
    Moose::Meta::Role objects as well as role names. This included

  - Moose::Meta::Class->does_role
  - Moose::Meta::Role->does_role
  - Moose::Util::does_role
  - Moose::Util::apply_all_roles
  - Moose::Util::ensure_all_roles
  - Moose::Util::search_class_by_role

  Requested by Shawn Moore. Addresses RT #51143 (and then some). (Dave Rolsky)


  - Fix handling of non-alphanumeric attributes names like '@foo'. This should
    work as long as the accessor method names are explicitly set to valid Perl
    method names. Reported by Doug Treder. RT #53731. (Dave Rolsky)

0.93_03   2010-01-05


  - Portability fixes to our XS code so we compile with 5.8.8 and Visual
    C++. Fixes RT #53391. Reported by Taro Nishino. (rafl)

0.93_02   2010-01-05


  - Depend on Class::MOP 0.97_01 so we can get useful results from CPAN
    testers. (Dave Rolsky)

0.93_01   2010-01-04


  See Moose::Manual::Delta for more details on backwards compatiblity issues.

  - Role attributes are now objects of the Moose::Meta::Role::Attribute
    class. (Dave Rolsky).

  - There were major changes to how metaroles are applied. We now distinguish
    between metaroles for classes vs those for roles. See the
    Moose::Util::MetaRole docs for details. (Dave Rolsky)

  - The old MetaRole API has been deprecated, but will continue to
    work. However, if you are applying an attribute metaclass role, this may
    break because of the fact that roles now have an attribute metaclass
    too. (Dave Rolsky)

  - Moose::Util::MetaRole::apply_metaclass_roles is now called
    apply_metaroles. The old name is deprecated. (Dave Rolsky)

  - The unimport subs created by Moose::Exporter now clean up re-exported
    functions like blessed and confess, unless the caller imported them from
    somewhere else too. See Moose::Manua::Delta for backcompat details. (rafl)


  - Changed the Str constraint to accept magic lvalue strings like one gets from
    substr et al, again. (sorear)

  - Sped up the type constraint parsing regex. (Sam Vilain)

  - The Moose::Cookbook::Extending::Recipe2 recipe was broken. Fix suggested by

  - Added Moose::Util::TypeConstraints exports when using to allow
    easier testing of TypeConstraints from the command line. (perigrin)

  - Added a with_immutable test function to Test::Moose, to run a block of tests
    with and without certain classes being immutable. (doy)

  - We now use Module::Install extensions explicitly to avoid confusing errors
    if they're not installed. We use Module::Install::AuthorRequires to stop
    test extraction and general failures if you don't have the author side
    dependencies installed.

  - Fixed a grammar error in Moose::Cookbook::Basics::Recipe4.
    #51791. (Amir E. Aharoni)

0.93   2009-11-19
    - Moose::Object
      - Calling $object->new() is no longer deprecated, and no longer
        warns. (doy)

    - Moose::Meta::Role
      - The get_attribute_map method is now deprecated. (Dave Rolsky)

    - Moose::Meta::Method::Delegation
      - Preserve variable aliasing in @_ for delegated methods, so that
        altering @_ affects the passed value. (doy)

    - Moose::Util::TypeConstraints
      - Allow array refs for non-anonymous form of enum and duck_type, not
        just anonymous. The non-arrayref forms may be removed in the
        future. (doy)
      - Changed Str constraint to not accept globs (*STDIN or *FOO). (chansen)
      - Properly document Int being a subtype of Str. (doy)

    - Moose::Exporter
      - Moose::Exporter using modules can now export their functions to the
        main package. This applied to Moose and Moose::Role, among
        others. (nothingmuch)

    - Moose::Meta::Attribute
      - Don't remove attribute accessors we never installed, during
        remove_accessors. (doy)

    - Moose::Meta::Attribute::Native::Trait::Array
      - Don't bypass prototype checking when calling List::Util::first, to
        avoid a segfault when it is called with a non-code argument. (doy)

    - Moose::Meta::Attribute::Native::Trait::Code
      - Fix passing arguments to code execute helpers. (doy)

0.92   2009-09-22
    - Moose::Util::TypeConstraints
      - added the match_on_type operator (Stevan)
        - added tests and docs for this (Stevan)

    - Moose::Meta::Class
      - Metaclass compat fixing should already happen recursively, there's no
        need to explicitly walk up the inheritance tree. (doy)

    - Moose::Meta::Attribute
      - Add tests for set_raw_value and get_raw_value. (nothingmuch)

0.91   2009-09-17
    - Moose::Object
      - Don't import any functions, in order to avoid polluting our namespace
        with things that can look like methods (blessed, try, etc)

    - Moose::Meta::Method::Constructor
      - The generated code needs to called Scalar::Util::blessed by its
        fully-qualified name or else Perl can interpret the call to blessed as
        an indirect method call. This broke Search::GIN, which in turn broke
        KiokuDB. (nothingmuch)

0.90   2009-09-15
    - Moose::Meta::Attribute::Native::Trait::Counter
    - Moose::Meta::Attribute::Native::Trait::String
      - For these two traits, an attribute which did not explicitly provide
        methods to handles magically ended up delegating *all* the helper
        methods. This has been removed. You must be explicit in your handles
        declaration for all Native Traits. (Dave Rolsky)

    - Moose::Object
      - DEMOLISHALL behavior has changed. If any DEMOLISH method dies, we make
        sure to rethrow its error message. However, we also localize $@ before
        this so that if all the DEMOLISH methods success, the value of $@ will
        be preserved. (nothingmuch and Dave Rolsky)
      - We now also localize $? during object destruction. (nothingmuch and
        Dave Rolsky)
      - The handling of DEMOLISH methods was broken for immutablized classes,
        which were not receiving the value of
      - These two fixes address some of RT #48271, reported by Zefram.
      - This is all now documented in Moose::Manual::Construction.
      - Calling $object->new() is now deprecated. A warning will be
        issued. (perigrin)

    - Moose::Meta::Role
      - Added more hooks to customize how roles are applied. The role
        summation class, used to create composite roles, can now be changed
        and/or have meta-roles applied to it. (rafl)
      - The get_method_list method no longer explicitly excludes the "meta"
        method. This was a hack that has been replaced by better hacks. (Dave

    - Moose::Meta::Method::Delegation
      - fixed delegated methods to make sure that any modifiers attached to
        the accessor being delegated on will be called (Stevan)
        - added tests for this (Stevan)

    - Moose::Meta::Class
      - Moose no longer warns when a class that is being made immutable has
        mutable ancestors. While in theory this is a good thing to warn about,
        we found so many exceptions to this that doing this properly became
        quite problematic.

0.89_02   2009-09-10
    - Moose::Meta::Attribute::Native
      - Fix Hash, which still had 'empty' instead of 'is_empty'. (hdp)

    - Moose::Meta::Attribute::Native::Trait::Array
      - Added a number of functions from List::Util and List::MoreUtils,
        including reduce, shuffle, uniq, and natatime. (doy)

    - Moose::Exporter
      - This module will now generate an init_meta method for your exporting
        class if you pass it options for
        Moose::Util::MetaRole::apply_metaclass_roles or
        apply_base_class_roles. This eliminates a lot of repetitive
        boilerplate for typical MooseX modules. (doy).
      - Documented the with_meta feature, which is a replacement for
        with_caller. This feature was added by josh a while ago.
      - The with_caller feature is now deprecated, but will not issue a
        warning yet. (Dave Rolsky)
      - If you try to wrap/export a subroutine which doesn't actually exist,
        Moose::Exporter will warn you about this. (doy)

    - Moose::Meta::Role::Application::ToRole
      - When a role aliased a method from another role, it was only getting
        the new (aliased) name, not the original name. This differed from what
        happens when a class aliases a role's methods. If you _only_ want the
        aliased name, make sure to also exclue the original name. (Dave

0.89_01   2009-09-02
    - Moose::Meta::Attribute
      - Added the currying syntax for delegation from AttributeHelpers to the
        existing delegation API. (hdp)

    - Moose::Meta::Attribute::Native
      - We have merged the functionality of MooseX::AttributeHelpers into the
        Moose core with some API tweaks. You can continue to use
        MooseX::AttributeHelpers, but it will not be maintained except
        (perhaps) for critical bug fixes in the future. See
        Moose::Manual::Delta for details. (hdp, jhannah, rbuels, Sartak,
        perigrin, doy)

    - Moose::Error::Croak
    - Moose::Error::Confess
      - Clarify documentation on how to use different error-throwing
        modules. (Curtis Jewell)

    - Moose
      - Correct POD for builder to point to Recipe8, not 9. (gphat)

    - Moose::Exporter
      - When a nonexistent sub name is passed to as_is, with_caller, or
        with_meta, throw a warning and skip the exporting, rather than
        installing a broken sub. (doy)

    - Moose::Meta::Class
      - Moose now warns if you call C<make_immutable> for a class with mutable
        ancestors. (doy)

0.89   2009-08-13
    - Moose::Manual::Attributes
      - Clarify "is", include discussion of "bare". (Sartak)

    - Moose::Meta::Role::Method::Conflicting
    - Moose::Meta::Role::Application::ToClass
      - For the first set of roles involved in a conflict, report all
        unresolved method conflicts, not just the first method. Fixes #47210
        reported by Ovid. (Sartak)

    - Moose::Meta::TypeConstraint
      - Add assert_valid method to use a TypeConstraint for assertion (rjbs)

    - Moose::Exporter
      - Make "use Moose -metaclass => 'Foo'" do alias resolution, like -traits
        does. (doy)
      - Allow specifying role options (alias, excludes, MXRP stuff) in the
        arrayref passed to "use Moose -traits" (doy)

    - Moose::Util
      - Add functions meta_class_alias and meta_attribute_alias for creating
        aliases for class and attribute metaclasses and metatraits. (doy)

    - Moose::Meta::Attribute
    - Moose::Meta::Method::Accessor
      - A trigger now receives the old value as a second argument, if the
        attribute had one. (Dave Rolsky)

    - Moose::Meta::Method::Constructor
      - Fix a bug with $obj->new when $obj has stringify overloading.
        Reported by Andrew Suffield [ #47882] (Sartak)
        - However, we will probably deprecate $obj->new, so please don't start
          using it for new code!

    - Moose::Meta::Role::Application
    - Moose::Meta::Role::Application::RoleSummation
      - Rename alias and excludes to -alias and -excludes (but keep the old
        names for now, for backcompat) (doy)

0.88   2009-07-24
    - Moose::Manual::Contributing
      - Re-write the Moose::Manual::Contributing document to reflect
        the new layout and methods of work for the Git repository. All
        work now should be done in topic branches and reviewed by a
        core committer before being applied to master. All releases
        are done by a cabal member and merged from master to
        stable. This plan was devised by Yuval, blame him. (perigrin)

    - Moose::Meta::Role
      - Create metaclass attributes for the different role application
        classes.  (rafl)

    - Moose::Util::MetaRole
      - Allow applying roles to a meta role's role application
        classes. (rafl)

    - Moose::Meta::Attribute
      - Add weak_ref to allowed options for "has '+foo'" (mst)

    - Moose::Meta::Method::Accessor
      - No longer uses inline_slot_access in accessors, to support
        non-lvalue-based meta instances. (sorear)

0.87   2009-07-07
    - Moose::Meta::Method::Delegation
      - Once again allow class names as well as objects for
        delegation. This was changed in 0.86.

0.86   2009-07-03
    - Moose::Meta::Class::Immutable::Trait
      - Fixes to work with the latest Class::MOP.

    - Moose::Meta::Method::Delegation
      - Delegation now dies with a more useful error message if the
        attribute's accessor returns something defined but
        unblessed. (hdp)

0.85   2009-06-26
    - Moose::Meta::Attribute
      - The warning for 'no associated methods' is now split out into
        the _check_associated_methods method, so that extensions can
        safely call 'after install_accessors => ...'. This fixes a
        warning from MooseX::AttributeHelpers. (hdp)

0.84   2009-06-26
    - Moose::Role
      - has now sets definition_context for attributes defined in
        roles. (doy)

    - Moose::Meta::Attribute
      - When adding an attribute to a metaclass, if the attribute has
        no associated methods, it will give a deprecation
        warning. (hdp)
      - Methods generated by delegation were not being added to
        associated_methods. (hdp)
      - Attribute accessors (reader, writer, accessor, predicate,
        clearer) now warn if they overwrite an existing method. (doy)
      - Attribute constructors now warn very noisily about unknown (or
        misspelled) arguments

    - Moose::Util::TypeConstraints
      - Deprecated the totally useless Role type name, which just
        checked if $object->can('does'). Note that this is _not_ the
        same as a type created by calling role_type('RoleName').

    - Moose::Util::TypeConstraints
    - Moose::Meta::TypeConstraint::DuckType
      - Reify duck type from a regular subtype into an actual class
        - Document this because Sartak did all my work for me

    - Moose::Meta::Attribute
      - Allow Moose::Meta::TypeConstraint::DuckType in handles, since
        it is just a list of methods (Sartak)

    - Moose::Meta::Role
      - The get_*_method_modifiers methods would die if the role had
        no modifiers of the given type (Robert Buels).

0.83   2009-06-23
    - Moose::Meta::Class
      - Fix _construct_instance not setting the special __MOP__ object
        key in instances of anon classes. (doy)

0.82   2009-06-21
    - Moose::Manual::Types
      - Mention MooseX::Types early to avoid users falling down the
        string parsing rathole (mst)

    - Moose::Manual::MooseX
      - Add warnings about class-level extensions and mention considering
        using plain objects instead

0.81   2009-06-07
    - Bumped our Class::MOP prereq to the latest version (0.85), since
      that's what we need.

0.80   2009-06-06
    - Moose::Manual::FAQ
      - Add FAQ about the coercion change from 0.76 because it came up
        three times today (perigrin)
        - Win doy $10 dollars because Sartak didn't think anybody
          would document this fast enough (perigrin)

    - Moose::Meta::Method::Destructor
      - Inline a DESTROY method even if there are no DEMOLISH methods
        to prevent unnecessary introspection in

    - Moose::*
      - A role's required methods are now represented by
        Moose::Meta::Role::Method::Required objects. Conflicts are now
        represented by Moose::Meta::Role::Method::Conflicting
        objects. The benefit for end-users in that unresolved
        conflicts generate different, more instructive, errors,
        resolving Ovid's #44895. (Sartak)

    - Moose::Role
      - Improve the error message of "extends" as suggested by Adam
        Kennedy and confound (Sartak)
      - Link to Moose::Manual::Roles from Moose::Role as we now have
        excellent documentation (Adam Kennedy)

    - Tests
      - Update test suite for subname change in Class::MOP
      - Add TODO test for infinite recursion in Moose::Meta::Class

0.79   2009-05-13
    - Tests
      - More fixes for Win32 problems. Reported by Robert Krimen.

    - Moose::Object
      - The DEMOLISHALL method could still blow up in some cases
        during global destruction. This method has been made more
        resilient in the face of global destruction's random garbage
        collection order.

    - Moose::Exporter
      - If you "also" a module that isn't loaded, the error message
        now acknowledges that (Sartak)

    - Moose
      - When your ->meta method does not return a Moose::Meta::Class,
        the error message gave the wrong output (Sartak)

0.78   2009-05-12
    - Moose::Cookbook::FAQ and Moose::Cookbook::WTF
      - Merged these documents into what is now Moose::Manual::FAQ

    - Moose::Unsweetened
      - Moved to Moose::Manual::Unsweetened

    - Moose::Cookbook::Basics::Recipes 9-12
      - Renamed to be 8-11, since recipe 8 did not exist

    - Moose::Exporter
      - Make Moose::Exporter import strict and warnings into packages
        that use it (doy)

    - Moose::Object
      - Fix DEMOLISHALL sometimes not being able to find DEMOLISH
        methods during global destruction (doy)

    - Moose::Meta::Class
    - Moose::Meta::Role::Application::ToClass
      - Track the Role::Application objects created during class-role
        consumption (Sartak)

    - Moose::Meta::Class
      - Fix metaclass incompatibility errors when extending a vanilla perl
        class which isa Moose class with a metaclass role applied (t0m)

    - Moose::Meta::Role
      - Add a role-combination hook, _role_for_combination, for the
        benefit of MooseX::Role::Parameterized (Sartak)

    - Tests
      - Some tests were failing on Win32 because they explicit checked
        warning output for newlines. Reported by Nickolay Platonov.

0.77   2009-05-02
    - Moose::Meta::Role
      - Add explicit use of Devel::GlobalDestruction and Sub::Name

    - Moose::Object
      - Pass a boolean to DEMOLISHALL and DEMOLISH indicating whether
        or not we are currently in global destruction (doy)
      - Add explicit use of Devel::GlobalDestruction and Sub::Name

    - Moose::Cookbook::FAQ
      - Reworked much of the existing content to be more useful to
        modern Moose hackers (Sartak)

    - Makefile.PL
      - Depend on Class::MOP 0.83 instead of 0.82_01.

0.76   2009-04-27
    - Moose::Meta::TypeConstraint
      - Do not run coercions in coerce() if the value already passes the type
        constraint (hdp)

    - Moose::Meta::TypeConstraint::Class
      - In validation error messages, specifically say that the value is not
        an instance of the class. This should alleviate some frustrating
        forgot-to-load-my-type bugs. #44639 (Sartak)

    - Moose::Meta::Role::Application::ToClass
      - Revert the class-overrides-role warning in favor of a solution outside
        of the Moose core (Sartak)

    - Tests
      - Make Test::Output optional again, since it's only used in a few files

0.75_01   2009-04-23
    - Moose::Meta::Role::Application::ToClass
      - Moose now warns about each class overriding methods from roles it
        consumes (Sartak)

    - Tests
      - Warnings tests have standardized on Test::Output which is now an
        unconditionally dependency (Sartak)

    - Moose::Meta::Class
      - Changes to immutabilization to work with Class::MOP 0.82_01+.

0.75   2009-04-20
    - Moose
    - Moose::Meta::Class
      - Move validation of not inheriting from roles from Moose::extends to
        Moose::Meta::Class::superclasses (doy)

    - Moose::Util
      - add ensure_all_roles() function to encapsulate the common "apply this
        role unless the object already does it" pattern (hdp)

    - Moose::Exporter
      - Users can now select a different metaclass with the "-metaclass"
        option to import, for classes and roles (Sartak)

    - Moose::Meta::Role
      - Make method_metaclass an attr so that it can accept a metarole
        application.  (jdv)

0.74   2009-04-07
    - Moose::Meta::Role
    - Moose::Meta::Method::Destructor
      - Include stack traces in the deprecation warnings.
        (Florian Ragwitz)

    - Moose::Meta::Class
      - Removed the long-deprecated _apply_all_roles method.

    - Moose::Meta::TypeConstraint
      - Removed the long-deprecated union method.

0.73_02   2009-04-06
    - More deprecations and renamings
      - Moose::Meta::Method::Constructor
        - initialize_body => _initialize_body (this is always called
          when an object is constructed)

    - Moose::Object
      - The DEMOLISHALL method could throw an exception during global
        destruction, meaning that your class's DEMOLISH methods would
        not be properly called. Reported by t0m.

    - Moose::Meta::Method::Destructor
      - Destructor inlining was totally broken by the change to the
        is_needed method in 0.72_01. Now there is a test for this
        feature, and it works again.

    - Moose::Util
      - Bold the word 'not' in the POD for find_meta (t0m)

0.73_01   2009-04-05
    - Moose::*
      - Call user_class->meta in fewer places, with the eventual goal
        of allowing the user to rename or exclude ->meta
        altogether. Instead uses Class::MOP::class_of. (Sartak)

    - Moose::Meta::Method::Accessor
      - If an attribute had a lazy default, and that value did not
        pass the attribute's type constraint, it did not get the
        message from the type constraint, instead using a generic
        message. Test provided by perigrin.

    - Moose::Util::TypeConstraints
      - Add duck_type keyword. It's sugar over making sure an object
        can() a list of methods. This is easier than jrockway's
        suggestion to fork all of CPAN. (perigrin)
        - add tests and documentation (perigrin)

    - Moose
      - Document the fact that init_meta() returns the target class's
        metaclass object. (hdp)

    - Moose::Cookbook::Extending::Recipe1
    - Moose::Cookbook::Extending::Recipe2
    - Moose::Cookbook::Extending::Recipe3
    - Moose::Cookbook::Extending::Recipe4
      - Make init_meta() examples explicitly return the metaclass and
        point out this fact. (hdp)

    - Moose::Cookbook::Basics::Recipe12
      - A new recipe, creating a custom meta-method class.

    - Moose::Cookbook::Meta::Recipe6
      - A new recipe, creating a custom meta-method class.

    - Moose::Meta::Class
    - Moose::Meta::Method::Constructor
      - Attribute triggers no longer receive the meta-attribute object
        as an argument in any circumstance. Previously, triggers
        called during instance construction were passed the
        meta-attribute, but triggers called by normal accessors were
        not. Fixes RT#44429, reported by Mark Swayne. (hdp)

    - Moose::Manual::Attributes
      - Remove references to triggers receving the meta-attribute object as an
        argument. (hdp)

    - Moose::Cookbook::FAQ
      - Remove recommendation for deprecated Moose::Policy and
        Moose::Policy::FollowPBP; recommend MooseX::FollowPBP
        instead. (hdp)

    - Many methods have been renamed with a leading underscore, and a
      few have been deprecated entirely. The methods with a leading
      underscore are consider "internals only". People writing
      subclasses or extensions to Moose should feel free to override
      them, but they are not for "public" use.

      - Moose::Meta::Class
        - check_metaclass_compatibility => _check_metaclass_compatibility

      - Moose::Meta::Method::Accessor
        - initialize_body => _initialize_body (this is always called
          when an object is constructed)
        - /(generate_.*_method(?:_inline)?)/ => '_' . $1

      - Moose::Meta::Method::Constructor
        - initialize_body => _initialize_body (this is always called
          when an object is constructed)
        - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
        - attributes => _attributes (now inherited from parent)
        - meta_instance => _meta_instance (now inherited from parent)

      - Moose::Meta::Role
        - alias_method is deprecated. Use add_method

0.73   2009-03-27
    - No changes from 0.72_01.

0.72_01   2009-03-26
    - Everything
      - Almost every module has complete API documentation. A few
        methods (and even whole classes) have been intentionally
        excluded pending some rethinking of their APIs.

    - Moose::Util::TypeConstraints
      - Calling subtype with a name as the only argument is now an
        exception. If you want an anonymous subtype do:

         my $subtype = subtype as 'Foo';

    - Moose::Cookbook::Meta::Recipe7
      - A new recipe, creating a custom meta-instance class.

    - Moose::Cookbook::Basics::Recipe5
      - Fix various typos and mistakes. Includes a patch from Radu

    - Moose::Cookbook::Basics::Recipe9
      - Link to this recipe from's builder blurb

    - Moose::Exporter
      - When wrapping a function with a prototype, Moose::Exporter now
        makes sure the wrapped function still has the same
        prototype. (Daisuke Maki)

    - Moose::Meta::Attribute
      - Allow a subclass to set lazy_build for an inherited
        attribute. (hdp)

    - Makefile.PL
      - Explicitly depend on Data::OptList. We already had this dependency
        via Sub::Exporter, but since we're using it directly we're
        better off with it listed. (Sartak)

    - Moose::Meta::Method::Constructor
      - Make it easier to subclass the inlining behaviour. (Ash

    - Moose::Manual::Delta
      - Details significant changes in the history of Moose, along
        with recommended workarounds.

    - Moose::Manual::Contributing
      - Contributor's guide to Moose.

    - Moose::Meta::Method::Constructor
      - The long-deprecated intialize_body method has been removed
        (yes, spelled like that).

    - Moose::Meta::Method::Destructor
      - This is_needed method is now always a class method.

    - Moose::Meta::Class
      - Changes to the internals of how make_immutable works to match
        changes in latest Class::MOP.

0.72   2009-02-23
    - Moose::Object
    - Moose::Meta::Method::Constructor
      - A mutable class accepted Foo->new(undef) without complaint,
        while an immutable class would blow up with an unhelpful
        error. Now, in both cases we throw a helpful error
        instead. Reported by doy.

0.71_01   2009-02-22
    - Moose::Cookbook
      - Hopefully fixed some POD errors in a few recipes that caused
        them to display weird on

    - Moose::Util::TypeConstraints
      - Calling type or subtype without the sugar helpers (as, where,
        message) is now deprecated.
      - The subtype function tried hard to guess what you meant, but
        often got it wrong. For example:

         my $subtype = subtype as 'ArrayRef[Object]';

        This caused an error in the past, but now works as you'd

    - Everywhere
      - Make sure is loaded before calling
        Moose->throw_error. This wasn't normally an issue, but could
        bite you in weird cases.

0.71   2009-02-19
    - Moose::Cookbook::Basics::Recipe11
      - A new recipe which demonstrates the use of BUILDARGS and
        BUILD. (Dave Rolsky)

    - Moose::Cookbook::Roles::Recipe3
      - A new recipe, applying a role to an object instance. (Dave

    - Moose::Exporter
      - Allow overriding specific keywords from "also" packages. (doy)

    - Tests
      - Replace hardcoded cookbook tests with Test::Inline to ensure
        the tests match the actual code in the recipes. (Dave Rolsky)

    - Moose::Cookbook
      - Working on the above turned up a number of little bugs in the
        recipe code. (Dave Rolsky)

    - Moose::Util::TypeConstraints::Optimized
      - Just use Class::MOP for the optimized ClassName check. (Dave

0.70   2009-02-14
    - Moose::Util::TypeConstraints
      - Added the RoleName type (stevan)
        - added tests for this (stevan)

    - Moose::Cookbook::Basics::Recipe3
      - Updated the before qw[left right] sub to be a little more
        defensive about what it accepts (stevan)
        - added more tests to t/000_recipies/basics/003_binary_tree.t

    - Moose::Object
      - We now always call DEMOLISHALL, even if a class does not
        define DEMOLISH. This makes sure that method modifiers on
        DEMOLISHALL work as expected. (doy)
        - added tests for this (EvanCarroll)

    - Moose::Util::MetaRole
      - Accept roles for the wrapped_method_metaclass (rafl)
        - added tests for this (rafl)

    - Moose::Meta::Attribute
      - We no longer pass the meta-attribute object as a final
        argument to triggers. This actually changed for inlined code a
        while back, but the non-inlined version and the docs were
        still out of date.

    - Tests
      - Some tests tried to use Test::Warn 0.10, which had bugs. Now
        they require 0.11. (Dave Rolsky)

    - Documentation
      - Lots of small changes to the manual, cookbook, and
        elsewhere. These were based on feedback from various
        users, too many to list here. (Dave Rolsky)

0.69   2009-02-12
    - Moose
      - Make some keyword errors use throw_error instead of croak
        since Moose::Exporter wraps keywords now (Sartak)

    - Moose::Cookbook::*
      - Revised every recipe for style and clarity. Also moved some
        documentation out of cookbook recipes and into Moose::Manual
        pages. This work was funded as part of the Moose docs grant
        from TPF. (Dave Rolsky)

    - Moose::Meta::Method::Delegation
      - If the attribute doing the delegation was not populated, the
        error message did not specify the attribute name
        properly. (doy)

0.68   2009-02-04
    - POD
      - Many spelling, typo, and formatting fixes by daxim.

    - Moose::Manual::Attributes
      - The NAME section in the POD used "Attribute" so search.cpan
        didn't resolve links from other documents properly.

    - Moose::Meta::Method::Overriden
      - Now properly spelled as Overridden. Thanks to daxim for
        noticing this.

0.67   2009-02-03
    - Moose::Manual::*
      - Lots of little typo fixes and a few clarifications. Several
        pages didn't have proper titles, and so weren't actually
        visible on Thanks to hanekomu for a variety
        of fixes and formatting improvements.

0.66   2009-02-03
    - Moose::Manual
      - This is a brand new, extensive manual for Moose. This aims to
        provide a complete introduction to all of Moose's
        features. This work was funded as part of the Moose docs grant
        from TPF. (Dave Rolsky)

    - Moose::Meta::Attribute
      - Added a delegation_metaclass method to replace a hard-coded
        use of Moose::Meta::Method::Delegation. (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - If you created a subtype and passed a parent that Moose didn't
        know about, it simply ignored the parent. Now it automatically
        creates the parent as a class type. This may not be what you
        want, but is less broken than before. (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - This module tried throw errors by calling Moose->throw_error,
        but it did not ensure that Moose was loaded first. This could
        cause very unhelpful errors when it tried to throw an error
        before Moose was loaded. (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - You could declare a name with subtype such as "Foo!Bar" that
        would be allowed, but if you used it in a parameterized type
        such as "ArrayRef[Foo!Bar]" it wouldn't work. We now do some
        vetting on names created via the sugar functions, so that they
        can only contain alphanumerics, ":", and ".". (Dave Rolsky)

0.65   2009-01-22
    - Moose and Moose::Meta::Method::Overridden
      - If an overridden method called super(), and then the
        superclass's method (not overridden) _also_ called super(),
        Moose went into an endless recursion loop. Test provided by
        Chris Prather. (Dave Rolsky)

    - Moose::Meta::TypeConstraint
      - All methods are now documented. (gphat)

    - t/100_bugs/011_DEMOLISH_eats_exceptions.t
      - Fixed some bogus failures that occurred because we tried to
        validate filesystem paths in a very ad-hoc and
        not-quite-correct way. (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - Added maybe_type to exports. See docs for details. (rjbs)

    - Moose
      - Added Moose::Util::TypeConstraints to the SEE ALSO
        section. (pjf)

    - Moose::Role
      - Methods created via an attribute can now fulfill a "requires"
        declaration for a role. (nothingmuch)

    - Moose::Meta::Method::*
      - Stack traces from inlined code will now report its line and
        file as being in your class, as opposed to in Moose
        guts. (nothingmuch).

0.64   2008-12-31
    - Moose::Meta::Method::Accessor
      - Always inline predicate and clearer methods (Sartak)

    - Moose::Meta::Attribute
      - Support for parameterized traits (Sartak)
      - verify_against_type_constraint method to avoid duplication
        and enhance extensibility (Sartak)

    - Moose::Meta::Class
      - Tests (but no support yet) for parameterized traits (Sartak)

    - Moose
      - Require Class::MOP 0.75+, which has the side effect of making
        sure we work on Win32. (Dave Rolsky)

0.63   2008-12-08
    - Moose::Unsweetened
      - Some small grammar tweaks and bug fixes in non-Moose example
        code. (Dave Rolsky)

0.62_02   2008-12-05
    - Moose::Meta::Role::Application::ToClass
      - When a class does not provide all of a role's required
        methods, the error thrown now mentions all of the missing
        methods, as opposed to just the first one found. Requested by
        Curtis Poe (RT #41119). (Dave Rolsky)

    - Moose::Meta::Method::Constructor
      - Moose will no longer inline a constructor for your class
        unless it inherits its constructor from Moose::Object, and
        will warn when it doesn't inline. If you want to force
        inlining anyway, pass "replace_constructor => 1" to
        make_immutable. Addresses RT #40968, reported by Jon
        Swartz. (Dave Rolsky)
      - The quoting of default values could be broken if the default
        contained a single quote ('). Now we use quotemeta to escape
        anything potentially dangerous in the defaults. (Dave Rolsky)

0.62_01   2008-12-03
    - Moose::Object
      - use the method->execute API for BUILDALL
        and DEMOLISHALL (Sartak)

    - Moose::Util::TypeConstraints
      - We now make all the type constraint meta classes immutable
        before creating the default types provided by Moose. This
        should make loading Moose a little faster. (Dave Rolsky)

0.62   2008-11-26
    - Moose::Meta::Role::Application::ToClass
      - fixed issues where excluding and aliasing the
        same methods for a single role did not work
        right (worked just fine with multiple
        roles) (stevan)
        - added test for this (stevan)

    - Moose::Meta::Role::Application::RoleSummation
      - fixed the error message when trying to compose
        a role with a role it excludes (Sartak)

    - Moose::Exporter
      - Catch another case where recursion caused the value
        of $CALLER to be stamped on (t0m)
        - added test for this (t0m)

    - Moose
      - Remove the make_immutable keyword, which has been
        deprecated since April. It breaks metaclasses that
        use Moose without no Moose (Sartak)

    - Moose::Meta::Attribute
      - Removing an attribute from a class now also removes delegation
        (handles) methods installed for that attribute (t0m)
        - added test for this (t0m)

    - Moose::Meta::Method::Constructor
      - An attribute with a default that looked like a number (but was
        really a string) would accidentally be treated as a number
        when the constructor was made immutable (perigrin)
        - added test for this (perigrin)

    - Moose::Meta::Role
      - create method for constructing a role
        dynamically (Sartak)
        - added test for this (Sartak)
      - anonymous roles! (Sartak)
        - added test for this (Sartak)

    - Moose::Role
      - more consistent error messages (Sartak)

    - Moose::Cookbook::Roles::Recipe1
      - attempt to explain why a role that just requires
        methods is useful (Sartak)

0.61   2008-11-07
    - Moose::Meta::Attribute
      - When passing a role to handles, it will be loaded if necessary

    - Moose::Meta::Class
      - Method objects returned by get_method (and other methods)
        Could end up being returned without an associated_metaclass
        attribute. Removing get_method_map, which is provided by
        Class::MOP::Class, fixed this. The Moose version did nothing
        different from its parent except introduce a bug. (Dave Rolsky)
        - added tests for this (jdv79)

    - Various
      - Added a $VERSION to all .pm files which didn't have one. Fixes
        RT #40049, reported by Adam Kennedy. (Dave Rolsky)

    - Moose::Cookbook::Basics::Recipe4
    - Moose::Cookbook::Basics::Recipe6
      - These files had spaces on the first line of the SYNOPSIS, as
        opposed to a totally empty line. According to RT #40432, this
        confuses POD parsers. (Dave Rolsky)

0.60   2008-10-24
    - Moose::Exporter
      - Passing "-traits" when loading Moose caused the
        exports to be broken. Reported by t0m. (Dave Rolsky)
        - Tests for this bug. (t0m)

    - Moose::Util
      - Change resolve_metaclass alias to use the new
        load_first_existing_class function. This makes it a lot
        simpler, and also around 5 times faster. (t0m)
      - Add caching to resolve_metaclass_alias, which gives an order
        of magnitude speedup to things which repeatedly call the
        Moose::Meta::Attribute->does method, notably MooseX::Storage

    - Moose::Util::TypeConstraint
      - Put back the changes for parameterized constraints that
        shouldn't have been removed in 0.59. We still cannot parse
        them, but MooseX modules can create them in some other
        way. See the 0.58 changes for more details. (jnapiorkowski)
      - Changed the way subtypes are created so that the job is
        delegated to a type constraint parent. This clears up some
        hardcoded checking and should allow correct subtypes of
        Moose::Meta::Type::Constraint. Don't rely on this new API too
        much (create_child_type) because it may go away in the
        future. (jnapiorkowski)

    - Moose::Meta::TypeConstraint::Union
      - Type constraint names are sorted as strings, not numbers.

    - Moose::Meta::TypeConstraint::Parameterizable
      - New parameterize method. This can be used as a factory method
        to make a new type constraint with a given parameterized
        type. (jnapiorkowski)
        - added tests (jnapiorkowski)

0.59   2008-10-14
    - Moose
      - Add abridged documentation for builder/default/initializer/
        predicate, and link to more details sections in
        Class::MOP::Attribute. (t0m)

    - Moose::Util::TypeConstraints
      - removed prototypes from all but the &-based stuff (mst)

    - Moose::Util::TypeConstraints
      - Creating a anonymous subtype with both a constraint and a
        message failed with a very unhelpful error, but should just
        work. Reported by t0m. (Dave Rolsky)

    - Tests
      - Some tests that used Test::Warn if it was available failed
        with older versions of Test::Warn. Reported by Fayland. (Dave
      - Test firing behavior of triggers in relation to builder/default/
        lazy_build. (t0m)
      - Test behavior of equals/is_a_type_of/is_subtype_of for all
        kinds of supported type. (t0m)

    - Moose::Meta::Class
      - In create(), do not pass "roles" option to the superclass
        - added related test that creates an anon metaclass with
          a required attribute

    - Moose::Meta::TypeConstraint::Class
    - Moose::Meta::TypeConstraint::Role
      - Unify behavior of equals/is_a_type_of/is_subtype_of with
        other types (as per change in 0.55_02). (t0m)

    - Moose::Meta::TypeConstraint::Registry
      - Fix warning when dealing with unknown type names (t0m)

    - Moose::Util::TypeConstraints
      - Reverted changes from 0.58 related to handle parameterized
        types. This caused random failures on BSD and Win32 systems,
        apparently related to the regex engine. This means that Moose
        can no longer parse structured type constraints like
        ArrayRef[Int,Int] or HashRef[name=>Str]. This will be
        supported in a slightly different way via MooseX::Types some
        time in the future. (Dave Rolsky)

0.58   2008-09-20
    !! This release has an incompatible change regarding !!
    !! how roles add methods to a class !!

    - Roles and role application
      ! Roles now add methods by calling add_method, not
        alias_method. They make sure to always provide a method
        object, which will be cloned internally. This means that it is
        now possible to track the source of a method provided by a
        role, and even follow its history through intermediate roles.

        This means that methods added by a role now show up when
        looking at a class's method list/map. (Dave Rolsky)

    - Makefile.PL
      - From this release on, we'll try to maintain a list of
        conflicting modules, and warn you if you have one
        installed. For example, this release conflicts with ...
        - MooseX::Singleton        <= 0.11
        - MooseX::Params::Validate <= 0.05
        - Fey::ORM                 <= 0.10

        In general, we try to not break backwards compatibility for
        most Moose users, but MooseX modules and other code which
        extends Moose's metaclasses is often affected by very small
        changes in the Moose internals.

    - Moose::Meta::Method::Delegation
    - Moose::Meta::Attribute
      - Delegation methods now have their own method class. (Dave

    - Moose::Meta::TypeConstraint::Parameterizable
      - Added a new method 'parameterize' which is basically a factory
        for the containing constraint. This makes it easier to create
        new types of parameterized constraints. (jnapiorkowski)

    - Moose::Meta::TypeConstraint::Union
      - Changed the way Union types canonicalize their names to follow
        the normalized TC naming rules, which means we strip all
        whitespace. (jnapiorkowski)

    - Moose::Util::TypeConstraints
      - Parameter and Union args are now sorted, this makes Int|Str
        the same constraint as Str|Int. (jnapiorkowski)
      - Changes to the way Union types are parsed to more correctly
        stringify their names. (jnapiorkowski)
      - When creating a parameterized type, we now use the new
        parameterize method. (jnapiorkowski)
      - Incoming type constraint strings are now normalized to remove
        all whitespace differences. (jnapiorkowski)
      - Changed the way we parse type constraint strings so that we now
        match TC[Int,Int,...] and TC[name=>Str] as parameterized type
        constraints. This lays the foundation for more flexible type
        constraint implementations.

    - Tests and docs for all the above. (jnapiorkowski)

    - Moose::Exporter
    - Moose
      - Moose::Exporter will no longer remove a subroutine that the
        exporting package re-exports. Moose re-exports the
        Carp::confess function, among others. The reasoning is that we
        cannot know whether you have also explicitly imported those
        functions for your own use, so we err on the safe side and
        always keep them. (Dave Rolsky)
        - added tests for this (rafl)

    - Moose::Meta::Class
      - Changes to how we fix metaclass compatibility that are much
        too complicated to go into. The summary is that Moose is much
        less likely to complain about metaclass incompatibility
        now. In particular, if two metaclasses differ because
        Moose::Util::MetaRole was used on the two corresponding
        classes, then the difference in roles is reconciled for the
        subclass's metaclass. (Dave Rolsky)
      - Squashed an warning in _process_attribute (thepler)

    - Moose::Meta::Role
      - throw exceptions (sooner) for invalid attribute names (thepler)
        - added tests for this (thepler)

    - Moose::Util::MetaRole
      - If you explicitly set a constructor or destructor class for a
        metaclass object, and then applied roles to the metaclass,
        that explicitly set class would be lost and replaced with the

    - Moose::Meta::Class
    - Moose::Meta::Attribute
    - Moose::Meta::Method
    - Moose
    - Moose::Object
    - Moose::Error::Default
    - Moose::Error::Croak
    - Moose::Error::Confess
      - All instances of confess() changed to use overridable
        C<throw_error> method. This method ultimately calls a class
        constructor, and you can change the class being called. In
        addition, errors now pass more information than just a string.
        The default C<error_class> behaves like C<Carp::confess>, so
        the behavior is not visibly different for end users.

0.57   2008-09-03
    - Moose::Intro
      - A new bit of doc intended to introduce folks familiar with
        "standard" Perl 5 OO to Moose concepts. (Dave Rolsky)

    - Moose::Unsweetened
      - Shows examples of two classes, each done first with and then
        without Moose. This makes a nice parallel to
        Moose::Intro. (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - Fixed a bug in find_or_parse_type_constraint so that it
        accepts a Moose::Meta::TypeConstraint object as the parent
        type, not just a name (jnapiorkowski)
        - added tests (jnapiorkowski)

    - Moose::Exporter
      - If Sub::Name was not present, unimporting failed to actually
        remove some sugar subs, causing test failures (Dave Rolsky)

0.56   2008-09-01
    For those not following the series of dev releases, there are
    several major changes in this release of Moose.
      ! Moose::init_meta should now be called as a method. See the
        docs for details.

      - Major performance improvements by nothingmuch.

      - New modules for extension writers, Moose::Exporter and
        Moose::Util::MetaRole by Dave Rolsky.

      - Lots of doc improvements and additions, especially in the
        cookbook sections.

      - Various bug fixes.

    - Removed all references to the experimental-but-no-longer-needed

    - Require Class::MOP 0.65.

0.55_04   2008-08-30
    - Moose::Util::MetaRole
    - Moose::Cookbook::Extending::Recipe2
      - This simplifies the application of roles to any meta class, as
        well as the base object class. Reimplemented metaclass traits
        using this module. (Dave Rolsky)

    - Moose::Cookbook::Extending::Recipe1
      - This a new recipe, an overview of various ways to write Moose
        extensions (Dave Rolsky)

    - Moose::Cookbook::Extending::Recipe3
    - Moose::Cookbook::Extending::Recipe4
      - These used to be Extending::Recipe1 and Extending::Recipe2,

0.55_03   2008-08-29
    - No changes from 0.55_02 except increasing the Class::MOP
      dependency to 0.64_07.

0.55_02   2008-08-29
    - Makefile.PL and
      - explicitly require Perl 5.8.0+ (Dave Rolsky)

    - Moose::Util::TypeConstraints
      - Fix warnings from find_type_constraint if the type is not
        found (t0m).

    - Moose::Meta::TypeConstraint
      - Predicate methods (equals/is_a_type_of/is_subtype_of) now
        return false if the type you specify cannot be found in the
        type registry, rather than throwing an unhelpful and
        coincidental exception. (t0m).
        - added docs & test for this (t0m)

    - Moose::Meta::TypeConstraint::Registry
      - add_type_constraint now throws an exception if a parameter is
        not supplied (t0m).
        - added docs & test for this (t0m)

    - Moose::Cookbook::FAQ
      - Added a faq entry on the difference between "role" and "trait"

    - Moose::Meta::Role
      - Fixed a bug that caused role composition to not see a required
        method when that method was provided by another role being
        composed at the same time. (Dave Rolsky)
        - test and bug finding (tokuhirom)

0.55_01   2008-08-20

    !! Calling Moose::init_meta as a function is now         !!
    !! deprecated. Please see the docs for details. !!

    - Moose::Meta::Method::Constructor
      - Fix inlined constructor so that values produced by default
        or builder methods are coerced as required. (t0m)
        - added test for this (t0m)

    - Moose::Meta::Attribute
      - A lazy attribute with a default or builder did not attempt to
        coerce the default value. The immutable code _did_
        coerce. (t0m)
        - added test for this (t0m)

    - Moose::Exporter
      - This is a new helper module for writing "Moose-alike"
        modules. This should make the lives of MooseX module authors
        much easier. (Dave Rolsky)

    - Moose
    - Moose::Cookbook::Meta::Recipe5
      - Implemented metaclass traits (and wrote a recipe for it):

          use Moose -traits => 'Foo'

        This should make writing small Moose extensions a little
        easier (Dave Rolsky)

    - Moose::Cookbook::Basics::Recipe1
      - Removed any examples of direct hashref access, and applied an
        editorial axe to reduce verbosity. (Dave Rolsky)

    - Moose::Cookbook::Basics::Recipe1
      - Also applied an editorial axe here. (Dave Rolsky)

    - Moose
    - Moose::Cookbook::Extending::Recipe1
    - Moose::Cookbook::Extending::Recipe2
      - Rewrote extending and embedding moose documentation and
        recipes to use Moose::Exporter (Dave Rolsky)

    - Moose
    - Moose::Role
      - These two modules now warn when you load them from the main
        package "main" package, because we will not export sugar to
        main. Previously it just did nothing. (Dave Rolsky)

    - Moose::Role
      - Now provide an init_meta method just like, and you
        can call this to provide an alternate role metaclass. (Dave
        Rolsky and nothingmuch)
      - get_method_map now respects the package cache flag (nothingmuch)

    - Moose::Meta::Role
      - Two new methods - add_method and wrap_method_body

    - many modules
      - Optimizations including allowing constructors to accept hash
        refs, making many more classes immutable, and making
        constructors immutable. (nothingmuch)

0.55   2008-08-03
    - Moose::Meta::Attribute
      - breaking down the way 'handles' methods are
        created so that the process can be more easily
        overridden by subclasses (stevan)

    - Moose::Meta::TypeConstraint
      - fixing what is passed into a ->message with
        the type constraints (RT #37569)
        - added tests for this (Charles Alderman)

    - Moose::Util::TypeConstraints
      - fix coerce to accept anon types like subtype can (mst)

    - Moose::Cookbook
      - reorganized the recipes into sections - Basics, Roles, Meta,
        Extending - and wrote abstracts for each section (Dave Rolsky)

    - Moose::Cookbook::Basics::Recipe10
      - A new recipe that demonstrates operator overloading
        in combination with Moose. (bluefeet)

    - Moose::Cookbook::Meta::Recipe1
      - an introduction to what meta is and why you'd want to make
        your own metaclass extensions (Dave Rolsky)

    - Moose::Cookbook::Meta::Recipe4
      - a very simple metaclass example (Dave Rolsky)

    - Moose::Cookbook::Extending::Recipe1
      - how to write a Moose-alike module to use your own object base
        class (Dave Rolsky)

    - Moose::Cookbook::Extending::Recipe2
      - how to write modules with an API just like C<> (Dave

    - all documentation
      - Tons of fixes, both syntactical and grammatical (Dave
        Rolsky, Paul Fenwick)

0.54   2008-07-03
    ... this is not my day today ...

    - Moose::Meta::Attribute
      - fixed legal_options_for_inheritance such that
        clone_and_inherit options still works for
        Class::MOP::Attribute objects and therefore
        does not break MooseX::AttributeHelpers

0.53   2008-07-03
    - Whoops, I guess I should run 'make manifest' before
      actually releasing the module. No actual changes
      in this release, except the fact that it includes
      the changes that I didn't include in the last
      release. (stevan--)

0.52   2008-07-03
    - Moose
      - added "FEATURE REQUESTS" section to the Moose docs
        to properly direct people (stevan) (RT #34333)
      - making 'extends' croak if it is passed a Role since
        this is not ever something you want to do
        (fixed by stevan, found by obra)
        - added tests for this (stevan)

    - Moose::Object
      - adding support for DOES (as in UNIVERSAL::DOES)
        - added test for this

    - Moose::Meta::Attribute
      - added legal_options_for_inheritance (wreis)
        - added tests for this (wreis)

    - Moose::Cookbook::Snacks::*
      - removed some of the unfinished snacks that should
        not have been released yet. Added some more examples
        to the 'Keywords' snack. (stevan)

    - Moose::Cookbook::Style
      - added general Moose "style guide" of sorts to the
        cookbook (nothingmuch) (RT #34335)

    - t/
      - added more BUILDARGS tests (stevan)

0.51   2008-06-26
    - Moose::Role
      - add unimport so "no Moose::Role" actually does
        something (sartak)

    - Moose::Meta::Role::Application::ToRole
      - when RoleA did RoleB, and RoleA aliased a method from RoleB in
        order to provide its own implementation, that method still got
        added to the list of required methods for consumers of
        RoleB. Now an aliased method is only added to the list of
        required methods if the role doing the aliasing does not
        provide its own implementation. See Recipe 11 for an example
        of all this. (Dave Rolsky)
        - added tests for this

    - Moose::Meta::Method::Constructor
      - when a single argument that wasn't a hashref was provided to
        an immutabilized constructor, the error message was very
        unhelpful, as opposed to the non-immutable error. Reported by
        dew. (Dave Rolsky)
        - added test for this (Dave Rolsky)

    - Moose::Meta::Attribute
      - added support for meta_attr->does("ShortAlias") (sartak)
        - added tests for this (sartak)
      - moved the bulk of the `handles` handling to the new
        install_delegation method (Stevan)

    - Moose::Object
      - Added BUILDARGS, a new step in new()

    - Moose::Meta::Role::Application::RoleSummation
      - fix typos no one ever sees (sartak)

    - Moose::Util::TypeConstraints
    - Moose::Meta::TypeConstraint
    - Moose::Meta::TypeCoercion
      - Attempt to work around the ??{ } vs. threads issue
        (not yet fixed)
      - Some null_constraint optimizations

0.50   2008-06-12
    - Fixed a version number issue by bumping all modules
      to 0.50.

0.49   2008-06-12
    !! This version now approx. 20-25% !!
    !! faster with new Class::MOP 0.59 !!

    - Moose::Meta::Attribute
      - fixed how the is => (ro|rw) works with
        custom defined reader, writer and accessor
        - added docs for this (TODO).
        - added tests for this (Thanks to Penfold)
      - added the custom attribute alias for regular
        Moose attributes which is "Moose"
      - fix builder and default both being used

    - Moose
      - switched usage of reftype to ref because

      - changing add_package_symbol to use the new
        HASH ref form

        - added test for this (thanks to Sartak)

    - Moose::Util::TypeConstraints
      - move the ClassName type check code to

0.48   2008-05-29
    (early morning release engineering)--

    - fixing the version in Moose::Meta::Method::Destructor
      which was causing the indexer to choke

0.47   2008-05-29
    (late night release engineering)--

    - fixing the version is META.yml, no functional
      changes in this release

0.46   2008-05-28
    !! This version now approx. 20-25% !!
    !! faster with new Class::MOP 0.57 !!

    - Moose::Meta::Class
      - some optimizations of the &initialize method
        since it is called so often by &meta

    - Moose::Meta::Class
      - now use the get_all_package_symbols from the
        updated Class::MOP, test suite is now 10 seconds

    - Moose::Meta::Method::Destructor
      - is_needed can now also be called as a class
        method for immutablization to check if the
        destructor object even needs to be created
        at all

    - Moose::Meta::Method::Destructor
      - added more descriptive error message to help
        keep people from wasting time tracking an error
        that is easily fixed by upgrading.

0.45   2008-05-24
    - Moose
      - Because of work in Class::MOP 0.57, all
        XS based functionality is now optional
        and a Pure Perl version is supplied
        - the CLASS_MOP_NO_XS environment variable
          can now be used to force non-XS versions
          to always be used
        - several of the packages have been tweaked
          to take care of this, mostly we added
          support for the package_name and name
          variables in all the Method metaclasses
      - before/around/after method modifiers now
        support regexp matching of names
        (thanks to Takatoshi Kitano)
        - tests added for this
        - NOTE: this only works for classes, it
          is currently not supported in roles,
          but, ... patches welcome
      - All usage of Carp::confess have been replaced
        by Carp::croak in the "keyword" functions since
        the stack trace is usually not helpful

    - Moose::Role
      - All usage of Carp::confess have been replaced
        by Carp::croak in the "keyword" functions since
        the stack trace is usually not helpful
      - The 'has' keyword for roles now accepts the
        same array ref form that does
        (has [qw/foo bar/] => (is => 'rw', ...))
        - added test for this

    - Moose::Meta::Attribute
      - trigger on a ro-attribute is no longer an
        error, as it's useful to trigger off of the

    - Moose::Meta::Class
      - added same 'add_package_symbol' fix as in
        Class::MOP 0.57

    - Moose::Util
      - does_role now handles non-Moose classes
        more gracefully
        - added tests for this
      - added the 'add_method_modifier' function
        (thanks to Takatoshi Kitano)

    - Moose::Util::TypeConstraints
      - subtypes of parameterizable types now are
        themselves parameterizable types

        called by the inlined immutable
        - added test for this (thanks to Caelum)

    - Moose::Meta::Role::Application::ToInstance
      - now uses the metaclass of the instance
        (if possible) to create the anon-class
        (thanks Jonathan Rockway)

    - Moose::Cookbook::Recipe22
      - added the meta-attribute trait recipe
        (thanks to Sartak)

    - t/
      - fixed hash-ordering test bug that was
        causing occasional cpantester failures
      - renamed the t/000_recipe/*.t tests to be
        more descriptive (thanks to Sartak)

0.44   2008-05-10
    - Moose
      - made make_immutable warning cluck to
        show where the error is (thanks mst)

    - Moose::Object
      - BUILDALL and DEMOLISHALL now call
        ->body when looping through the
        methods, to avoid the overloaded
        method call.
      - fixed issue where DEMOLISHALL was
        eating the $@ values, and so not
        working correctly, it still kind of
        eats them, but so does vanilla perl
        - added tests for this

    - Moose::Cookbook::Recipe7
      - added new recipe for immutable
        functionality (thanks Dave Rolsky)

      - fixed Win32 test failure (thanks spicyjack)

    ~ removed Build.PL and Module::Build compat
      since Module::Install has done that.

0.43   2008-04-30
        drink more coffee before
        doing release engineering

    - whoops, forgot to do the smolder tests,
      and we broke some of the custom meta-attr
      modules. This fixes that.

0.42   2008-04-28
    - some bad tests slipped by, nothing else
      changed in this release (cpantesters++)

    - upped the Class::MOP dependency to 0.55
      since we have tests which need the C3

    - Changed all usage of die to Carp::croak for better
      error reporting (initial patch by Tod Hagan)

0.39   2008-03-14
    - Moose
      - documenting the use of '+name' with attributes
        that come from recently composed roles. It makes
        sense, people are using it, and so why not just
        officially support it.
      - fixing the 'extends' keyword so that it will not
        trigger Ovid's bug (

    - t/
      - making test for using '+name' on attributes consumed
        from a role, it works and makes sense too.

    - Moose::Meta::Attribute

        when the method cannot be found, not sure why
        it ever did this originally, this means we now

0.34   2008-01-21
    ~~~ more misc. doc. fixes ~~~
    ~~ updated copyright dates ~~

    Moose is now a postmodern object system :)
      - (see the POD for details)

    - <<Role System Refactoring>>
    - this release contains a major reworking and
      cleanup of the role system
      - 100% backwards compat.
      - Role application now restructured into seperate
        classes based on type of applicants
      - Role summation (combining of more than one role)
        is much cleaner and anon-classes are no longer
        used in this process
      - new Composite role metaclass
      - runtime application of roles to instances
        is now more efficient and re-uses generated
        classes when applicable

    - <<New Role composition features>>
      - methods can now be excluded from a given role
        during composition
      - methods can now be aliased to another name (and
        still retain the original as well)

    - Moose::Util::TypeConstraints::OptimizedConstraints
      - added this module (see above)

    - Moose::Meta::Class
      - fixed the &_process_attribute method to be called

        an accessor would get (incorrectly) ignored.
        Thanks to Sartak for finding this ;)
        - added tests for this (Sartak again)

    - Moose::Meta::Method::Accessor
      - lots of cleanup of such things as:
        - generated methods
        - type constraint handling
        - error handling/messages
        (thanks to nothingmuch)

    - Moose::Meta::TypeConstraint::Parameterizable
      - added this module to support the refactor
        in Moose::Meta::TypeConstraint::Parameterized

    - Moose::Meta::TypeConstraint::Parameterized
      - refactored how these types are handled so they
        are more generic and not confined to ArrayRef
        and HashRef only

    - t/
      - shortened some file names for better VMS support (RT #32381)

0.33   2007-12-14
    !! Moose now loads 2 x faster !!
    !!  with new Class::MOP 0.49  !!

    ++ new module to make command line
       Moose-ness easier (see POD docs for more)

    - Moose::Meta::Class

        HashRef for containers (sartak)
        - added tests for this

    - Moose::Meta::TypeCoercion
      - coercions will now create subtypes as needed
        so you can now add coercions to parameterized
        types without having to explictly define them
        - added tests for this

    - Moose::Meta::Method::Accessor
      - allow subclasses to decide whether we need
        to copy the value into a new variable (sartak)

0.32   2007-12-04
    - Moose::Util::TypeConstraints
      - fixing how subtype aliases of unions work
        they should inherit the parent's coercion
        - added tests for this

        having to do it all in one place
        - added tests for this

    - Moose::Meta::TypeConstraint
      - there is now a default constraint of sub { 1 }
        instead of Moose::Util::TypeConstraints setting
        this for us

    - Moose::Meta::TypeCoercion
    - Moose::Meta::TypeCoercion::Union
      - added the &has_coercion_for_type and
        &add_type_coercions methods to support the
        new features above (although you cannot add
        more type coercions for Union types)

0.31   2007-11-26
    - Moose::Meta::Attribute
      - made the +attr syntax handle extending types with
        parameters. So "has '+foo' => (isa => 'ArrayRef[Int]')"
        now works if the original foo is an ArrayRef.
        - added tests for this.
      - delegation now works even if the attribute does not
        have a reader method using the get_read_method_ref
        method from Class::MOP::Attribute.
        - added tests for this
        - added docs for this

    - Moose::Util::TypeConstraints
      - passing no "additional attribute info" to
        &find_or_create_type_constraint will no longer
        attempt to create an __ANON__ type for you,
        instead it will just return undef.
        - added docs for this

0.30   2007-11-23

        methods from a class (thanks to confound).
        - added tests for this

    - Moose::Util::TypeConstraint
      - fixed the type notation parser so that
        the | always creates a union and so is
        no longer a valid type char (thanks to
        konobi, mugwump and #moose for working
        this one out.)
        - added more tests for this

0.26   2007-09-27
    == New Features ==

    - Parameterized Types
      We now support parameterized collection types, such as:
          ArrayRef[Int]    # array or integers
          HashRef[Object]  # a hash with object values
      They can also be nested:
          ArrayRef[HashRef[RegexpRef]] # an array of hashes with regex values
      And work with the type unions as well:
          ArrayRef[Int | Str]  # array of integers of strings

    - Better Framework Extendability is now "extendable" such that it is now much
      easier to extend the framework and add your own keywords
      and customizations. See the "EXTENDING AND EMBEDDING MOOSE"
      section of the docs.

    - Moose Snacks!
      In an effort to begin documenting some of the various
      details of Moose as well as some common idioms, we have
      created Moose::Cookbook::Snacks as a place to find
      small (easily digestable) nuggets of Moose code.

    ~ Several doc updates/cleanup thanks to castaway ~

    - converted build system to use Module::Install instead of
      Module::Build (thanks to jrockway)

    - Moose
      - added all the meta classes to the immutable list and
        set it to inline the accessors
      - fix import to allow Sub::Exporter like { into => }
            and { into_level => } (perigrin)
      - exposed and documented init_meta() to allow better
            embedding and extending of Moose (perigrin)

        - t/
          - complete re-organization of the test suite
          - added some new tests as well
          - finally re-enabled the Moose::POOP test since
            the new version of DBM::Deep now works again
            (thanks rob)

    - Moose::Meta::Class
      - fixed very odd and very nasty recursion bug with
        inner/augment (mst)
        - added tests for this (eilara)

        assumptions about hash based classes (thanks to dexter)

    - Moose::Coookbook::Snacks
      - these are bits of documentation, not quite as big as
        Recipes but which have no clear place in the module docs.
        So they are Snacks! (horray for castaway++)

    - Moose::Cookbook::Recipe4
      - updated it to use the new ArrayRef[MyType] construct
        - updated the accompanying test as well

    +++ Major Refactor of the Type Constraint system +++
    +++       with new features added as well        +++

    - Moose::Util::TypeConstraint
      - no longer uses package variable to keep track of
        the type constraints, now uses the an instance of

        (thanks to mugwump)
        - added tests for this

      - added the package_defined_in attribute so that we
        can track where the type constraints are created

    - Moose::Meta::TypeConstraint::Union
      - this is now been refactored to be a subclass of

    - Moose::Meta::TypeCoercion::Union
      - this has been added to service the newly refactored
        Moose::Meta::TypeConstraint::Union and is itself
        a subclass of Moose::Meta::TypeCoercion

      - added (has_)hand_optimized_constraint to this class so that
        it behaves as the regular Moose::Meta::TypeConstraint does.

    - Moose::Meta::Role
      - large refactoring of this code
      - added several more tests
        - tests for subtle conflict resolition issues
          added, but not currently running
          (thanks to kolibre)

0.24   2007-07-03
    ~ Some doc updates/cleanup ~

    - Moose::Meta::Attribute
      - added support for roles to be given as parameters
        to the 'handles' option.
        - added tests and docs for this
      - the has '+foo' attribute form now accepts changes to
        the lazy option, and the addition of a handles option
        (but not changing the handles option)
        - added tests and docs for this

    - Moose::Meta::Role
      - required methods are now fetched using find_method_by_name
        so that required methods can come from superclasses
        - adjusted tests for this

0.23   2007-06-18
    - Moose::Meta::Method::Constructor
      - fix inlined constructor for hierarchy with multiple BUILD methods (mst)
    - Moose::Meta::Class
      - Modify make_immutable to work with the new Class::MOP immutable
        mechanism + POD + very basic test (groditi)
    - Moose::Meta::Attribute
      - Fix handles to use goto() so that caller() comes out properly on
        the other side (perigrin)

0.22   2007-05-31
    - Moose::Util::TypeConstraints
      - fix for prototype undeclared issue when Moose::Util::TypeConstraints
        loaded before consumers (e.g. Moose::Meta::Attribute) by predeclaring
        prototypes for functions
      - added the ClassName type constraint, this checks for strings
        which will respond true to ->isa(UNIVERSAL).
        - added tests and docs for this

        - tests added for this
      - fix reader presedence bug in Moose::Meta::Attribute + tests

    - Moose::Object
      - Foo->new(undef) now gets ignored, it is assumed you meant to pass
        a HASH-ref and missed. This produces better error messages then
        having it die cause undef is not a HASH.
        - added tests for this

0.21   2007-05-03
    - Moose
      - added SUPER_SLOT and INNER_SLOT class hashes to support unimport

       many many thanks to rlb3 and Aankhen for these :)

0.20   2007-04-06
    >> I messed up the SKIP logic in one test
       so this release is just to fix that.

    - Moose
      - 'has' now also accepts an ARRAY ref
        to create multiple attrs (see docs)
        (thanks to konobi for this)
         - added tests and docs

0.19   2007-04-05
    ~~ More documentation updates ~~

    - Moose::Util::TypeConstraints
      - 'type' now supports messages as well
        thanks to phaylon for finding this
        - added tests for this
      - added &list_all_type_constraints and
        functions to facilitate introspection.

    - Moose::Meta::Attribute
      - fixed regexp 'handles' declarations
        to build the list of delegated methods
        correctly (and not override important
        things like &new) thanks to ashleyb
        for finding this
        - added tests and docs for this
      - added the 'documentation' attributes
        so that you can actually document your
        attributes and inspect them through the
        - added tests and docs for this

    - Moose::Meta::Class
      - when loading custom attribute metaclasses
        it will first look in for the class in the
        Moose::Meta::Attribute::Custom::$name, and
        then default to just loading $name.
        - added tests and docs for this

    - Moose::Meta::TypeConstraint
      - type constraints now stringify to their names.
        - added test for this

    - misc.
      - added tests to assure we work with Module::Refresh
      - added stricter test skip logic in the Moose POOP
        test, ask Rob Kinyon why.
        - *cough* DBM::Deep 1.0 backwards compatibility sucks *cough* ;)

0.18   2007-03-10
    ~~ Many, many documentation updates ~~

    - misc.
      - We now use Class::MOP::load_class to
        load all classes.
      - added tests to show types and subtypes
        working with Declare::Constraints::Simple
        and Test::Deep as constraint engines.

0.18_001   2006-11-26
    !! You must have Class::MOP 0.37_001  !!
    !! for this developer release to work !!

    This release was primarily adding the immutable
    feature to Moose. An immutable class is one which
    you promise not to alter. When you set the class
    as immutable it will perform various bits of
    memoization and inline certain part of the code
    (constructors, destructors and accessors). This
    minimizes (and in some cases totally eliminates)
    one of Moose's biggest performance hits. This
    feature is not on by default, and is 100% optional.
    It has several configurable bits as well, so you
    can pick and choose to your specific needs.

    The changes involved in this were fairly wide and
    highly specific, but 100% backwards compatible, so
    I am not going to enumerate them here. If you are
    truely interested in what was changed, please do
    a diff :)

0.17   2006-11-14
    - Moose::Meta::Method::Accessor
      - bugfix for read-only accessors which
        are have a type constraint and lazy.
        Thanks to chansen for finding it.

0.16   2006-11-14
    ++ NOTE ++
    There are some speed improvements in this release,
    but they are only the begining, so stay tuned.

    - Moose::Object
      - BUILDALL and DEMOLISHALL no longer get
        called unless they actually need to be.
        This gave us a signifigant speed boost
        for the cases when there is no BUILD or
        DEMOLISH method present.

    - Moose::Util::TypeConstraints
    - Moose::Meta::TypeConstraint
      - added an 'optimize_as' option to the
        type constraint, which allows for a
        hand optimized version of the type
        constraint to be used when possible.
      - Any internally created type constraints
        now provide an optimized version as well.

0.15   2006-11-05
    ++ NOTE ++
    This version of Moose *must* have Class::MOP 0.36 in order
    to work correctly. A number of small internal tweaks have
    been made in order to be compatible with that release.

    - Moose::Util::TypeConstraints
      - added &unimport so that you can clean out
        your class namespace of these exported

    - Moose::Meta::Class
      - fixed minor issue which occasionally
        comes up during global destruction
        (thanks omega)
      - moved Moose::Meta::Method::Overriden into
        its own file.

    - Moose::Meta::Role
      - moved Moose::Meta::Role::Method into
        its own file.

    - Moose::Meta::Attribute
      - changed how we do type checks so that
        we reduce the overall cost, but still
        retain correctness.
       *** API CHANGE ***
      - moved accessor generation methods to
        Moose::Meta::Method::Accessor to
        conform to the API changes from
        Class::MOP 0.36

    - Moose::Meta::TypeConstraint
      - changed how constraints are compiled
        so that we do less recursion and more
        iteration. This makes the type check
        faster :)
      - moved Moose::Meta::TypeConstraint::Union
        into its own file

    - Moose::Meta::Method::Accessor
      - created this from methods formerly found in

    - Moose::Meta::Role::Method
      - moved this from Moose::Meta::Role

    - Moose::Meta::Method::Overriden
      - moved this from Moose::Meta::Class

    - Moose::Meta::TypeConstraint::Union
      - moved this from Moose::Meta::TypeConstraint

0.14   2006-10-09

    - Moose::Meta::Attribute
      - fixed lazy attributes which were not getting
        checked with the type constraint (thanks ashley)
        - added tests for this
      - removed the over-enthusiastic DWIMery of the
        automatic ArrayRef and HashRef defaults, it
        broke predicates in an ugly way.
        - removed tests for this

0.13   2006-09-30
    ++ NOTE ++
    This version of Moose *must* have Class::MOP 0.35 in order
    to work correctly. A number of small internal tweaks have
    been made in order to be compatible with that release.

    - Moose
      - Removed the use of UNIVERSAL::require to be a better
        symbol table citizen and remove a dependency
        (thanks Adam Kennedy)

      **~~ removed experimental & undocumented feature ~~**
      - commented out the 'method' and 'self' keywords, see the
        comments for more info.

    - Moose::Cookbook
      - added a FAQ and WTF files to document frequently
        asked questions and common problems

    - Moose::Util::TypeConstraints
      - added GlobRef and FileHandle type constraint
        - added tests for this

    - Moose::Meta::Attribute
      - if your attribute 'isa' ArrayRef of HashRef, and you have
        not explicitly set a default, then make the default DWIM.
        This will also work for subtypes of ArrayRef and HashRef
        as well.
      - you can now auto-deref subtypes of ArrayRef or HashRef too.
        - new test added for this (thanks to ashley)

    - Moose::Meta::Role
      - added basic support for runtime role composition
        but this is still *highly experimental*, so feedback
        is much appreciated :)
        - added tests for this

    - Moose::Meta::TypeConstraint
      - the type constraint now handles the coercion process
        through delegation, this is to support the coercion
        of unions

    - Moose::Meta::TypeConstraint::Union
      - it is now possible for coercions to be performed
        on a type union
        - added tests for this (thanks to konobi)

    - Moose::Meta::TypeCoercion
      - properly capturing error when type constraint
        is not found

    - Build.PL
      - Scalar::Util 1.18 is bad on Win32, so temporarily
        only require version 1.17 for Win32 and cygwin.
        (thanks Adam Kennedy)

0.12   2006-09-01
    - Moose::Cookbook
      - Recipe5 (subtypes & coercion) has been written

    - Moose
      - fixed "bad meta" error message to be more descriptive
      - fixed &unimport to not remove the &inner and &super
        keywords because we need to localize them.
      - fixed number of spelling/grammer issues, thanks Theory :)

      **~~ experimental & undocumented feature ~~**
      - added the method and self keywords, they are basically
        just sugar, and they may not stay around.

    - Moose::Object
      - added &dump method to easily Data::Dumper
        an object

    - Moose::Meta::TypeConstraint
      - added the &is_a_type_of method to check both the current
        and the subtype of a method (similar to &isa with classes)

    - Moose::Meta::Role
      - this is now a subclass of Class::MOP::Module, and no longer
        creates the _role_meta ugliness of before.
        - fixed tests to reflect this change

0.11   2006-07-12
    - Moose
      - added an &unimport method to remove all the keywords
        that Moose will import, simply add 'no Moose' to the
        bottom of your class file.

    - t/
      - fixed some test failures caused by a forgotten test

0.10   2006-07-06
    - Moose
      - improved error message when loading modules so
        it is less confusing when you load a role.
      - added &calculate_all_roles method to
        Moose::Meta::Class and Moose::Meta::Role

    This module has been tested against Class::MOP 0.30
    but it does not yet utilize the optimizations
    it makes available. Stay tuned for that ;)

0.09_03   2006-06-23
    - Moose
      - 'use strict' and 'use warnings' are no longer
         needed in Moose classes, Moose itself will
         turn them on for you.
         - added tests for this
      - moved code from exported subs to private methods
        in Moose::Meta::Class

    - Moose::Role
      - as with Moose, strict and warnings are
        automatically turned on for you.
         - added tests for this

    - Moose::Meta::Role
      - now handles an edge case for override errors
        - added tests for this
      - added some more edge case tests

0.09_02   2006-05-16
    - Moose
      - added prototypes to the exported subs
      - updated docs

    - Moose::Role
      - added prototypes to the exported subs

    - Moose::Util::TypeConstraints
      - cleaned up prototypes for the subs
      - updated docs

0.09_01   2006-05-12
      - This release works in combination with
        Class::MOP 0.29_01, it is a developer
        release because it uses the a new
        instance sub-protocol and a fairly
        complete Role implementation. It has
        not yet been optimized, so it is slower
        than the previous CPAN version. This
        release also lacks good updated docs,
        the official release will have updated docs.

    - Moose
      - refactored the keyword exports
        - 'with' now checks Role validaity and
          accepts more than one Role at a time
        - 'extends' makes metaclass adjustments as
           needed to ensure metaclass compatibility

    - Moose::Role
      - refactored the keyword exports
        - 'with' now checks Role validaity and
          accepts more than one Role at a time

    - Moose::Util::TypeConstraints
      - added the 'enum' keyword for simple
        string enumerations which can be used as
        type constraints
        - see example of usage in t/202_example.t

    - Moose::Object
      - more careful checking of params to new()

    - Moose::Meta::Role
      - much work done on the role composition
        - many new tests for conflict detection
          and composition edge cases
        - not enough documentation, I suggest
          looking at the tests

    - Moose::Meta::Instance
      - added new Instance metaclass to support
        the new Class::MOP instance protocol

    - Moose::Meta::Class
      - some small changes to support the new
        instance protocol
      - some small additions to support Roles

    - Moose::Meta::Attribute
      - some improvements to the accessor generation code
        by nothingmuch
      - some small changes to support the new
        instance protocol
      - (still somewhat) experimental delegation support
        with the 'handles' option
        - added several tests for this
        - no docs for this yet

0.05   2006-04-27
    - Moose
      - keywords are now exported with Sub::Exporter
        thanks to chansen for this commit
      - has keyword now takes a 'metaclass' option
        to support custom attribute meta-classes
        on a per-attribute basis
        - added tests for this
      - the 'has' keyword not accepts inherited slot
        specifications (has '+foo'). This is still an
        experimental feature and probably not finished
        see t/038_attribute_inherited_slot_specs.t for
        more details, or ask about it on #moose

        to nothingmuch and chansen for his help and advice
        on this

      - added required methods and correct handling of
        them in apply() for both classes and roles
        - added tests for this
      - no longer adds a does() method to consuming classes
        it relys on the one in Moose::Object
