  Reported by: Dan McCormick

[Changes for 1.05 (JSON::Syck 0.29) - 2008-06-09]

* The 'Name "YAML::Syck::ImplicitBinary" used only once: possible typo'
  warnings no longer triggers in Perl 5.10 when running with perl -w.
  Reported by: Jesse Vincent

[Changes for 1.03 (JSON::Syck 0.29) - 2008-02-16]

* JSON::Syck: When $JSON::Syck::SingleQuote is false, implicit booleans
  such as "yes" and "no" should be dumped with double quotes, instead of
  single quotes (which breaks RFC 4627).
  Reported by: cho45

[Changes for 1.02 (JSON::Syck 0.28) - 2008-02-16]

* JSON::Syck: Colons in single-quoted strings are no longer loaded
  with an extra space after it.
  Reported by: Agent Zhang

[Changes for 1.01 (JSON::Syck 0.27) - 2008-01-19]

  to further reduce our memory footprint.

[Changes for 1.00 (JSON::Syck 0.26) - 2007-12-10]

* When $YAML::Syck::SingleQuote is set to true, Dump() now emits newlines
  in strings correctly.  (Previously it would emit extra newlines.)

[Changes for 0.99 (JSON::Syck 0.26) - 2007-10-23]

* TODOify tests as appropriate for Perl 5.005 and Perl 5.6.x.

[Changes for 0.98 (JSON::Syck 0.26) - 2007-10-13]

[Changes for 0.97 (JSON::Syck 0.26) - 2007-09-03]

* When loading !!perl/code with $YAML::Syck::LoadCode set to false,
  YAML::Syck now returns a coderef that does nothing (i.e. sub {}),
  in accordance with YAML.pm's treatment, instead of returning the
  actual code of the sub as a string.
  Contributed by: Florian Ragwitz

[Changes for 0.96 (JSON::Syck 0.26) - 2007-08-08]

* The always-quote rule now applies to all implicit booleans
  and null values, i.e. strings that match the following regex:

    /y|Y
    |n|N
    |yes|Yes|YES
    |no|No|NO
    |true|True|TRUE
    |false|False|FALSE
    |on|On|ON
    |off|Off|OFF
    |null|Null|NULL
    |~
    /x

* Bare literals "Y", "N", "y" and "n" are now recognized as
  booleans when loading with implicit typing turned on.

* Mixed case strings that does not represent implicit boolean
  values, such as "yES" and "nO", are no longer always-quoted.
  Contributed by: Malcolm Studd

[Changes for 0.95 (JSON::Syck 0.26) - 2007-08-04]

* "Yes" and "no" (including all upper/lower case forms) are now
  always dumped in quoted form to avoid ambiguities when loaded
  by loaders with ImplicitTyping set to true.
  Reported by: Malcolm Studd

* lib/YAML/Syck.pod is merged back into lib/YAML/Syck.pm.
  (No functional changes.)

[Changes for 0.94 (JSON::Syck 0.26) - 2007-07-10]

* Repair broken PAUSE upload, again. (Sigh.)

[Changes for 0.93 (JSON::Syck 0.26) - 2007-07-10]

  ($fh) and (\*FH).  Also, new tests for LoadFile and DumpFile.
  Contributed by: Adriano Ferreira

[Changes for 0.91 (JSON::Syck 0.26) - 2007-06-23]

* Corrected loading Regexps with all combinations of quantifiers.
  Contributed by: Ingy döt Net

[Changes for 0.90 (JSON::Syck 0.26) - 2007-06-22]

* Regexes are now dump/loaded correctly with modifiers, with a new
  representation: "--- !!perl/regexp:main (?i-xsm:1)", instead of the
  old mapping with a REGEXP key.  The old form still loads correctly;
  the new form corresponds to YAML.pm 0.63 and later.
  Requested by: Ingy döt Net

* Loading regexes with modifiers no longer involves an eval"" call.

[Changes for 0.88 (JSON::Syck 0.26) - 2007-06-17]

* New dependency: Scalar::Util, for LoadFile and DumpFile functions.
  You can safely do without that module if you do not make use of the
  two functions.

* LoadFile and DumpFile now accept glob values, and reject unopened
  handles properly instead of silently ignores it.
  Contributed by: Adriano Ferreira

[Changes for 0.87 (JSON::Syck 0.25) - 2007-06-17]

* New LoadFile and DumpFile functions for JSON::Syck.

  Requested by: Adriano Ferreira

[Changes for 0.86 (JSON::Syck 0.24) - 2007-06-16]

* Support for dumping and loading regexps created by qr//, including
  blessed once.  Note that loading Regexp values dumped by YAML.pm
  currently discards modifiers.

[Changes for 0.85 (JSON::Syck 0.24) - 2007-04-20]

* Strings containing both single quotes and newlines were incorrectly 
  quoted with backslash-escaped single quotes.  This is a regression
  introduced in YAML::Syck 0.84.
  Reported by: Agent Zhang

[Changes for 0.84 (JSON::Syck 0.23) - 2007-04-02]

* New $YAML::Syck::SingleQuote flag: When it is set to true, Dump will
  always emit quotes instead of bare strings.
  Requested by: Ingo Bax

* When $JSON::Syck::SingleQuote is set to true, special characters such as
  \r\n are still escaped as usual, because JavaScript allows the same form
  of escaping in strings with either quotes.
  Reported by: Dobrica Pavlinusic

[Changes for 0.83 (JSON::Syck 0.22) - 2007-02-05]

* Under JSON::Syck, as well as YAML::Syck when $ImplicitTyping is set to
  true, integer numbers larger than an unsigned integer (>=4294967296 on
  32-bit platforms) was erroneously loaded as 0.
  Reported by: Markus Wörle

[Changes for 0.82 (JSON::Syck 0.21) - 2007-01-26]

* Bytestrings containing no high bit bytes are no longer dumped as "!binary".

  Base64-encoded "!binary" type.

* JSON::Syck now raises an exception, instead of segfaults,
  when dumping a circular structure.

[Changes for 0.80 (JSON::Syck 0.20) - 2007-01-26]

* LICENSING CHANGE: This compilation and all individual files in it
  (except for the bundled libsyck code) are now under the permissive
  "MIT" license.  See the COPYRIGHT section in README for the new terms.

* Load("!! []") no longer segfaults due to empty tag names.

* Load("!!Foo []") now blesses into "Foo", not "Foo::\0".

* Load("!!perl/scalar 123") is now \123, not 123.

* Load("!!perl/scalar:Foo ~") is now \"Foo", not undef.

* Dump(bless(\$undef, 'Foo')) is now "!!perl/scalar:Foo ~", not "~".

[Changes for 0.72 (JSON::Syck 0.15) - 2006-11-26]

  lines, which confused YAML.pm terribly.
  Reported by: Nelson Elhage

[Changes for 0.70 (JSON::Syck 0.14) - 2006-10-02]

* Load()/Dump()/LoadFile()/DumpFile() in YAML::Syck now support
  multiple YAML streams -- i.e. dumping multiple Perl values into a
  string composed of several YAML streams, and loading such a string
  into several values under list context.

  YAML 1.1 implementations.

[Changes for 0.46_02 (JSON::Syck 0.13) - 2006-06-29]

  blessed references work: See http://pyyaml.org/wiki/PerlTagScheme
  for the new specification.

  versions of YAML loaders (both YAML::Syck and YAML.pm), although it
  will still load YAML streams produced by earlier loaders.
