3.012 Dec 6 2015
* Yet another release related to broken META files.
ExtUtils::MakeMaker and CPAN::Meta need to be up to date
or the META files miss stuff.
3.011 Dec 6 2015
* No significant changes. Doc typo fixes, and build tweaks.
3.010 Dec 1 2015
* Build fixes.
3.009 Nov 30 2015
* Re-relase 3.008 with updated META files.
3.008 Nov 27 2015
* FIX: Win32 build issues.
3.007 Nov 26 2015
* Build fixes for boxes without any Sereal installed (it seems
to be common on certain types of smokers, and not on others).
* [ENCODER]: new sort orders added.
* Fix incremental parsing of utf8 strings. See
https://rt.cpan.org/Public/Bug/Display.html?id=93892
* Encoder fixes.
3.006 Nov 14 2015
* [DECODER] fix segfaults from heavily corrupted data. Guards
against various pathological cases which could cause segfaults
fixed. Thanks to Damian Gryski and "fuzzing sereal with afl"
for finding these cases.
* [ENCODER] Various subtle fixes to how we choose whether to serialize
the string or numeric version of a value, in particular to
ensure that "00" always round trips as "00", and related issues.
Note this fix has correctness and performance consequences. In
some cases values that used to serialized as integers (arguably
incorrectly) will be serialized as strings instead, and some code
maybe be slower to serialize.
NOTE: Some issues related to this subject are not fixable without
a protocol change. In particular this change may affect the behavior
of code that uses binary logical operators on values serialized
with Perl.
Thanks to Zefram, Tom, and others for help with this issue.
* Fixups for cast warnings under -Wint-to-ptr builds by using
using PTR2INT and INT2PTR for casting our objects.
* Win32 fixes
* Build improvements
* Changes to how we generate constants
3.005 Jan 05 2015
* Build improvements related to char signedness being platform
dependent.
3.004 Dec 27 2014
* Performance optimizations and other miscellaneous changes.
* Build improvements.
* Win32 fixes for weakrefs.
3.003 Oct 19 2014
* Niko Tyni fixed the 64-bit big endian Sereal bug! (Yay Niko!)
* Sereal::Decoder::Constants will now have a defined $VERSION
* Setup META.yml correctly so that certain dependencies are
marked as being test dependencies and not build or run-time
dependencies.
* Allow one to build against an externally supplied version
of csnappy or miniz. Thanks to Petr Písař <ppisar@redhat.com>
3.002 Aug 20 2014
* Summary of changes from 3.001 - 3.002
- Introduce "set_readonly" option to decoder
- Introduce "set_readonly_scalars" option to decoder
* Bug fixes
- Fix assertion fails in DEBUG perls (Brian Fraser)
- Fix segfault with "into" interface when decoding references and
strings into the same target SV. See new test t/550_decode_into.t
* Test Infra Changes
- Split up bulk tests to speed up testing and make it easier
to see when a failure is restricted to a specific option.
* Big-Endian Support
- Improved support for Big-Endian machines. We now build and pass test
on Sparc and HP-UX and other platforms with big-endian or strict
alignedness requirements. Much thanks to Jarkko Hietaniemi,
Gregor Herrmann, and H. Merijn Brand for for their assistance with
this.
- We still have issues with s390x (Z/Os) with Sereal. If someone wants
to help it would be appreciated.
3.001
- Upgrade to version 3 of the protocol
* Add Zlib compression support to the protocol
* Add Zlib support to Encoder/Decoder
* Add CANONICAL_UNDEF tag to represent PL_sv_undef
* Change magic header so it is trivial to detect
and reject utf8 encoded Sereal packets.
- Change how we serialize variables which have more
than one of IOK, NOK, and POK set. In general we
favour the numeric form, with the exception of when
all three are set when we favour the string form
(this is to handle engineering notation like "0E0"
where numeric and string equivalence may differ)
