version 0.007; 2012-02-11
* be thread-safe, by mutex control on op check hooking
* in pure Perl implementation, avoid putting extra eval stack frames
around the require, to avoid unnecessary complication of exception
handling; this can't be done on Perls 5.9.4 to 5.10.0, so don't
allow use of the pure Perl implementation on those Perls
* revise documentation to suggest loading this module earlier
* document the relevant changes to the Perl core in more detail
* on Perl versions where the pure Perl implementation can't work,
dynamically declare requirement for XS infrastructure in Build.PL
* refine threshold for ability to correctly override require from
5.8.0 to 5.7.2
* revise minimum required Perl version down from 5.6.1 to 5.6.0
* test that modules see the correct context at file scope
* test that module return values are handled correctly
* test that the module doesn't generate warnings
* in pure Perl implementation, fix handling of the variable that
previously needed to be "our"
* rearrange and better comment the treatment of lexical warnings in
the Perl code
version 0.006; 2011-11-20
* bugfix: avoid loading warnings.pm and leaving its delayed requires
of Carp.pm susceptible to hint leakage, which was causing trouble
on some Perls
* skip swash test on Perl 5.6, where swash loading appears to be broken
by loading Test::More or anything else useful
* remove bogus tests that cause false failures on Perl 5.15.5
* in Build.PL, declare incompatibility with pre-0.19
B::Hooks::OP::Check, which doesn't play nicely around op check hooking
* comment why a variable surprisingly needs to be "our"
* convert .cvsignore to .gitignore
version 0.005; 2011-07-25
* bugfix: work around core bug [perl #73174] affecting Unicode swash
loading, and apply entire workaround arrangement to 5.11.{0..5}
where [perl #73174] exists but [perl #68590] does not
* correct dynamic_config setting to 0
* include META.json in distribution
* add MYMETA.json to .cvsignore
version 0.004; 2010-11-21
* bugfix: don't attempt to use XS version of the workaround on Win32,
where it can't work properly due to linker restriction on access to
core symbols
* only define PERL_CORE for compilation on Perl versions where the
bug workaround (and thus interference with core-private stuff)
is actually necessary
* in XS, use PERL_NO_GET_CONTEXT for efficiency
* in XS, declare "PROTOTYPES: DISABLE" to prevent automatic generation
of unintended prototypes
* in XS, provide a reserve definition of croak, so that the Perl_croak
circumlocution is avoided even with PERL_CORE defined
* in XS, give symbolic names to the Perl version thresholds
* jump through hoops to avoid compiler warnings
* use full stricture in test suite
* also test POD coverage of pure Perl implementation
* in t/setup_pp.pl, avoid a warning that occurs if XSLoader::load()
is given no arguments, which is now a valid usage
* in Build.PL, explicitly set needs_compiler to avoid bogus
auto-dependency on ExtUtils::CBuilder
* in Build.PL, complete declaration of configure-time requirements
version 0.003; 2010-04-10
* bugfix: in pure-Perl implementation, make sure ambient package (from
which require is invoked) is passed on correctly to the code in the
required file, on those Perls where it is so inherited
* in XS, use macros to avoid explicit passing of aTHX, in the manner
of the core
* in XS, avoid using "class" as a variable name, for compatibility
with C++ compilers
* make all numeric comparisons against $] stringify it first, to avoid
architecture-dependent problems with floating point rounding giving
it an unexpected numeric value
* in Build.PL, explicitly declare configure-time requirements
* add MYMETA.yml to .cvsignore
version 0.002; 2009-10-21
* generate a more normal-looking op tree, that doesn't crash B::Deparse
* don't apply the workaround on Perl 5.11.0 or later, where the bug
has been fixed
* in t/seal.t, test that cop_hints_hash is properly handled
* check for required Perl version at runtime
version 0.001; 2009-09-26
* bugfix: die cleanly if the pure-Perl implementation is needed but
won't work (which occurs on pre-5.8 perls)
* bugfix: avoid undesired warning from pure-Perl implementation if
require has already been overridden via CORE::GLOBAL::require
* in tests, set HINT_LOCALIZE_HH where appropriate, to avoid false
test failures on pre-5.10 perls
* test that the module plays nicely with code that overrides require
via CORE::GLOBAL::require
version 0.000; 2009-09-22
* initial released version
