Revision history for Perl extension Sereal-Encoder

****************************************************************
* Warning: For a seamless upgrade, upgrade to version 3        *
*          of the decoder before upgrading to version 3 of the *
*          encoder!                                            *
****************************************************************
3.005_004 Nov 13 2015
  * [DECODER] Build/test fixes and improvements. We were getting
  * a bunchof false test fails from fixing bugs. The round trip
  * version checks have been fixed.

3.005_003 Nov 11 2015
  * We can't serialize copies of false (ie, pv="" iv=0, POK/IOK)
    as FALSE.
  * Add missing Changes update for 3.005_002
  * Fixups for cast warnings under -Wint-to-ptr builds by using
    using PTR2INT and INT2PTR for casting our objects.

3.005_002 Nov 08 2015
  * 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.

3.005_001 Jan 27 2015
  * 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!)
  * 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 "canonical" option to encoder
  - Introduce "canonical_refs" option to encoder

  * 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)
