        - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean)
          as well (reported by Alex Efros).
        - allow literal tabs in strings in relaxed mode (patch by
          lubo.rintel@gooddata.com).
        - support "cbor" format in json_xs tool.
        - support (and fix) calling encode and decode in list context
          (reported by Вадим Власов).

3.01 Tue Oct 29 16:55:15 CET 2013
        - backport to perls < 5.18 (reported by Paul Howarth).

3.0  Tue Oct 29 01:35:37 CET 2013
        - implemented an object tagging extension (using the
          Types::Serialiser serialisation protocol).
        - reworked the documentation regarding object serialisation,
          add a new OBJECT SERIALISATION section that explains th
          whole process.
        - new setting: allow_tags.
        - switch to Types::Serialiser booleans.
        - remove to_json/from_json.
        - other minor improvements to the documentation.

2.34 Thu May 23 11:30:34 CEST 2013
        - work around bugs in perl 5.18 breaking more than 100
          widely used modules, without a fix in sight because
          p5pers don't care about CPAN anymore.
        - when canonicalising, only allocate up to 64 hash key
          pointers on the stack. for larger hashes, use the heap,
          to avoid using too much stackspace.
        - discuss the problem with setlocale (reported by a few victims).

2.33 Wed Aug  1 21:03:52 CEST 2012
        - internal encode/decode XS wrappers did not expect stack
          moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
        - add bencode as to/from option in bin/json_xs.
        - add -e option to json_xs, and none and string in/out formats.

2.32 Thu Aug 11 19:06:38 CEST 2011
        - fix a bug in the initial whitespace accumulation.

2.31 Wed Jul 27 17:53:05 CEST 2011
        - don't accumulate initial whitespace in the incremental buffer
          (this can be useful to allow whitespace-keepalive on a tcp
          connection without triggering the max_size limit).
        - properly croak on some invalid inputs that are not strings
          (e.g. undef) when trying to decode a json text (reported
          and analyzed by Goro Fuji).

2.3   Wed Aug 18 01:26:47 CEST 2010
        - make sure decoder doesn't change the decoding in the incremental
          parser (testcase provided by Hendrik Schumacher).
        - applied patch by DaTa for Data::Dumper support in json_xs.
        - added -t dump support to json_xs, using Data::Dump.
        - added -f eval support to json_xs.

2.29  Wed Mar 17 02:39:12 CET 2010
        - fix a memory leak when callbacks set using filter_json_object
          or filter_json_single_key_object were called (great testcase
          by Eric Wilhelm).

2.28  Thu Mar 11 20:30:46 CET 2010
        - implement our own atof function - perl's can be orders of
          magnitudes slower than even the system one. on the positive
          side, ours seems to be more exact in general than perl's.
          (testcase provided by Tim Meadowcroft).
        - clarify floating point conversion issues a bit.
        - update jpsykes csrf article url.
        - updated benchmark section - JSON::PP became much faster!

2.27  Thu Jan  7 07:35:08 CET 2010
        - support relaxed option inside the incremental parser
          (testcase provided by IKEGAMI via Makamaka).

2.26  Sat Oct 10 03:26:19 CEST 2009
        - big integers could become truncated (based on patch
          by Strobl Anton).
        - output format change: indent now adds a final newline, which is
          more expected and more true to the documentation.

2.25  Sat Aug  8 12:04:41 CEST 2009
        - the perl debugger completely breaks lvalue subs - try to work
          around the issue.
        - ignore RMAGICAL hashes w.r.t. CANONICAL.
        - try to work around a possible char signedness issue on aix.
        - require common sense.

2.24  Sat May 30 08:25:45 CEST 2009
        - the incremental parser did not update its parse offset
          pointer correctly when parsing utf8-strings (nicely
          debugged by Martin Evans).
        - appending a non-utf8-string to the incremental parser
          in utf8 mode failed to upgrade the string.
        - wording of parse error messages has been improved.

2.232 Sun Feb 22 11:12:25 CET 2009
        - use an exponential algorithm to extend strings, to
          help platforms with bad or abysmal==windows memory
          allocater performance, at the expense of some memory
          wastage (use shrink to recover this extra memory).
          (nicely analysed by Dmitry Karasik).

2.2311 Thu Feb 19 02:12:54 CET 2009
        - add a section "JSON and ECMAscript" to explain some
          incompatibilities between the two (problem was noted by
          various people).
        - add t/20_faihu.t.

2.231 Thu Nov 20 04:59:08 CET 2008
        - work around 5.10.0 magic bugs where manipulating magic values
          (such as $1) would permanently damage them as perl would
          ignore the magicalness, by making a full copy of the string,
          reported by Dmitry Karasik.
        - work around spurious warnings under older perl 5.8's.

2.23 Mon Sep 29 05:08:29 CEST 2008
        - fix a compilation problem when perl is not using char * as, well,
          char *.
        - use PL_hexdigit in favour of rolling our own.

2.2222 Sun Jul 20 18:49:00 CEST 2008
        - same game again, broken 5.10 finds yet another assertion
          failure, and the workaround causes additional runtime warnings.
          Work around the next assertion AND the warning. 5.10 seriously
          needs to adjust it's attitude against working code.

2.222 Sat Jul 19 06:15:34 CEST 2008
        - you work around one -DDEBUGGING assertion bug in perl 5.10
          just to hit the next one. work around this one, too.

2.22 Tue Jul 15 13:26:51 CEST 2008
        - allow higher nesting levels in incremental parser.
        - error out earlier in some cases in the incremental parser
          (as suggested by Yuval Kogman).
        - improve incr-parser test (Yuval Kogman).

2.21 Tue Jun  3 08:43:23 CEST 2008
        - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
        - remove the experimental status of the incremental parser interface.
        - move =encoding around again, to avoid bugs with search.cpan.org.
          when can we finally have utf-8 in pod???
        - add ->incr_reset method.

2.2  Wed Apr 16 20:37:25 CEST 2008
        - lifted the log2 rounding restriction of max_depth and max_size.
        - make booleans mutable by creating a copy instead of handing out
          the same scalar (reported by pasha sadri).
        - added support for incremental json parsing (still EXPERIMENTAL).
        - implemented and added a json_xs command line utility that can convert
          from/to a number of serialisation formats - tell me if you need more.
        - implement allow_unknown/get_allow_unknown methods.
        - fixed documentation of max_depth w.r.t. higher and equal.
        - moved down =encoding directive a bit, too much breaks if it's the first
          pod directive :/.
        - removed documentation section on other modules, it became somewhat
          outdated and is nowadays mostly of historical interest.

2.1  Wed Mar 19 23:23:18 CET 2008
        - update documentation here and there: add a large section
          about utf8/latin1/ascii flags, add a security consideration
          and extend and clarify the JSON and YAML section.
        - medium speed enhancements when encoding/decoding non-ascii chars.
        - minor speedup in number encoding case.
        - extend and clarify the section on incompatibilities
          between YAML and JSON.
        - switch to static inline from just inline when using gcc.
        - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
        - fix some issues with UV to JSON conversion of unknown impact.
        - published the yahoo locals search result used in benchmarks as the
          original url changes so comparison is impossible.

2.01 Wed Dec  5 11:40:28 CET 2007
        - INCOMPATIBLE API CHANGE: to_json and from_json have been
          renamed to encode_json/decode_json for JSON.pm compatibility.
          The old functions croak and might be replaced by JSON.pm
          comaptible versions in some later release.

2.0  Tue Dec  4 11:30:46 CET 2007
        - this is supposed to be the first version of JSON::XS
          compatible with version 2.0+ of the JSON module.
          Using the JSON module as frontend to JSON::XS should be
          as fast as using JSON::XS directly, so consider using it
          instead.
        - added get_* methods for all "simple" options.
        - make JSON::XS subclassable.

1.53 Tue Nov 13 23:58:33 CET 2007
        - minor doc clarifications.
        - fixed many doc typos (patch by Thomas L. Shinnick).

1.52 Mon Oct 15 03:22:06 CEST 2007
        - remove =encoding pod directive again, it confuses too many pod
          parsers :/.

1.51 Sat Oct 13 03:55:56 CEST 2007
        - encode empty arrays/hashes in a compact way when pretty is enabled.
        - apparently JSON::XS was used to find some bugs in the
          JSON_checker testsuite, so add (the corrected) JSON_checker tests to
          the testsuite.
        - quite a bit of doc updates/extension.
        - require 5.8.2, as this seems to be the first unicode-stable version.

1.5  Tue Aug 28 04:05:38 CEST 2007
        - add support for tied hashes, based on ideas and testcase by
          Marcus Holland-Moritz.
        - implemented relaxed parsing mode where some extensions are being
          accepted. generation is still JSON-only.

1.44 Wed Aug 22 01:02:44 CEST 2007
        - very experimental process-emulation support, slowing everything down.
          the horribly broken perl threads are still not supported - YMMV.

1.43 Thu Jul 26 13:26:37 CEST 2007
        - convert big json numbers exclusively consisting of digits to NV
          only when there is no loss of precision, otherwise to string.

1.42 Tue Jul 24 00:51:18 CEST 2007
        - fix a crash caused by not handling missing array elements
          (report and testcase by Jay Kuri).

1.41 Tue Jul 10 18:21:44 CEST 2007
        - fix compilation with NDEBUG (assert side-effect),
          affects convert_blessed only.
        - fix a bug in decode filters calling ENTER; SAVETMPS;
          one time too often.
        - catch a typical error in TO_JSON methods.
        - antique-ised XS.xs again to work with outdated
          C compilers (windows...).

1.4  Mon Jul  2 10:06:30 CEST 2007
        - add convert_blessed setting.
        - encode did not catch all blessed objects, encoding their
          contents in most cases. This has been fixed by introducing
          the allow_blessed setting.
        - added filter_json_object and filter_json_single_key_object
          settings that specify a callback to be called when
          all/specific json objects are encountered.
        - assume that most object keys are simple ascii words and
          optimise this case, penalising the general case. This can
          speed up decoding by 30% in typical cases and gives
          a smaller and faster perl hash.
        - implemented simpleminded, optional resource size checking
          in decode_json.
        - remove objToJson/jsonToObj aliases, as the next version
          of JSON will not have them either.
        - bit the bullet and converted the very simple json object
          into a more complex one.
        - work around a bug where perl wrongly claims an integer
          is not an integer.
        - unbundle JSON::XS::Boolean into own pm file so Storable
          and similar modules can resolve the overloading when thawing.

1.3  Sun Jun 24 01:55:02 CEST 2007
        - make JSON::XS::true and false special overloaded objects
          and return those instead of 1 and 0 for those json atoms
          (JSON::PP compatibility is NOT achieved yet).
        - add JSON::XS::is_bool predicate to test for those special
          values.
        - add a reference to
          http://jpsykes.com/47/practical-csrf-and-json-security.
        - removed require 5.8.8 again, it is just not very expert-friendly.
          Also try to be more compatible with slightly older versions,
          which are not recommended (because they are buggy).

1.24 Mon Jun 11 05:40:49 CEST 2007
        - added informative section on JSON-as-YAML.
        - get rid of some c99-isms again.
        - localise dec->cur in decode_str, speeding up
          string decoding considerably (>15% on my amd64 + gcc).
        - increased SHORT_STRING_LEN to 16kb: stack space is
          usually plenty, and this actually saves memory
          when !shrinking as short strings will fit perfectly.

1.23 Wed Jun  6 20:13:06 CEST 2007
        - greatly improved small integer encoding and decoding speed.
        - implement a number of µ-optimisations.
        - updated benchmarks.

1.22 Thu May 24 00:07:25 CEST 2007
        - require 5.8.8 explicitly as older perls do not seem to offer
          the required macros.
        - possibly made it compile on so-called C compilers by microsoft.

1.21 Wed May  9 18:40:32 CEST 2007
        - character offset reported for trailing garbage was random.

1.2  Wed May  9 18:35:01 CEST 2007
        - decode did not work with magical scalars (doh!).
        - added latin1 flag to produce JSON texts in the latin1 subset
          of unicode.
        - flag trailing garbage as error.
        - new decode_prefix method that returns the number
          of characters consumed by a decode.
        - max octets/char in perls UTF-X is actually 13, not 11,
          as pointed out by Glenn Linderman.
        - fixed typoe reported by YAMASHINA Hio.

1.11 Mon Apr  9 07:05:49 CEST 2007
        - properly 0-terminate sv's returned by encode to help
          C libraries that expect that 0 to be there.
        - partially "port" JSON from C to microsofts fucking broken
          pseudo-C. They should be burned to the ground for pissing
          on standards. And I should be stoned for even trying to
          support this filthy excuse for a c compiler.

1.1  Wed Apr  4 01:45:00 CEST 2007
        - clarify documentation (pointed out by Quinn Weaver).
        - decode_utf8 sometimes did not correctly flag errors,
          leading to segfaults.
        - further reduced default nesting depth to 512 due to the test
          failure by that anonymous "chris" whose e-mail address seems
          to be impossible to get. Tests on other freebsd systems indicate
          that this is likely a problem in his/her configuration and not this
          module.
        - renamed json => JSON in error messages.
        - corrected the character offset in some error messages.

1.01 Sat Mar 31 16:15:40 CEST 2007
        - do not segfault when from_json/decode gets passed
          a non-string object (reported by Florian Ragwitz).
          This has no effect on normal operation.

1.0  Thu Mar 29 04:43:34 CEST 2007
        - the long awaited (by me) 1.0 version.
        - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
          true and false.
        - add some more notes to shrink, as suggested by Alex Efros.
        - improve testsuite.
        - halve the default nesting depth limit, to hopefully make it
          work on Freebsd (unfortunately, the cpan tester did not
          send me his report, so I cannot ask about the stack limit on fbsd).

0.8  Mon Mar 26 00:10:48 CEST 2007
        - fix a memleak when decoding hashes.
        - export jsonToBj and objToJson as aliases
          to to_json and from_json, to reduce incompatibilities
          between JSON/JSON::PC and JSON::XS. (experimental).
        - implement a maximum nesting depth for both en- and de-coding.
        - added a security considerations sections.

0.7  Sun Mar 25 01:46:30 CET 2007
        - code cleanup.
        - fix a memory overflow bug when indenting.
        - pretty-printing now up to 15% faster.
        - improve decoding speed of strings by
          up to 50% by specialcasing short strings.
        - further decoding speedups for strings using
          lots of \u escapes.
        - improve utf8 decoding speed for U+80 .. U+7FF.

0.5  Sat Mar 24 20:41:51 CET 2007
        - added the UTF-16 encoding example hinted at in previous
          versions.
        - minor documentation fixes.
        - fix a bug in and optimise canonicalising fastpath
          (reported by Craig Manley).
        - remove a subtest that breaks with bleadperl (reported
          by Andreas König).

0.31 Sat Mar 24 02:14:34 CET 2007
        - documentation updates.
        - do some casting to hopefully fix Andreas' problem.
        - nuke bogus json rpc stuff.

0.3  Fri Mar 23 19:33:21 CET 2007
        - remove spurious PApp::Util reference (John McNamara).
        - adapted lots of tests from other json modules
          (idea by Chris Carline).
        - documented mapping from json to perl and vice versa.
        - improved the documentation by adding more examples.
        - added short escaping forms, reducing the created
          json texts a bit.
        - added shrink flag.
        - when flag methods are called without enable argument
          they will by default enable their flag.
        - considerably improved string encoding speed (at least
          with gcc 4).
        - added a test that covers lots of different characters.
        - clarified some error messages.
        - error messages now use correct character offset
          with F_UTF8.
        - improve the "no bytes" and "no warnings" hacks in
          case the called functions do... stuff.
        - croak when encoding to ascii and an out-of-range
          (non-unicode) codepoint is encountered.

0.2  Fri Mar 23 00:23:34 CET 2007
        - the "could not sleep without debugging release".
          it should basically work now, with many bugs as
          no production tests have been run yet.
        - added more testcases.
        - the expected shitload of bugfixes.
        - handle utf8 flag correctly in decode.
        - fix segfault in decoder.
        - utf8n_to_uvuni sets retlen to -1, but retlen is an
          unsigned types (argh).
        - fix decoding of utf-8 strings.
        - improved error diagnostics.
        - fix decoding of 'null'.
        - fix parsing of empty array/hashes
        - silence warnings when we prepare the croak message.

0.1   Thu Mar 22 22:13:43 CET 2007
        - first release, very untested, basically just to claim
          the namespace.

22	root	1.161	3.0 Tue Oct 29 01:35:37 CET 2013
23			- implemented an object tagging extension (using the
24	root	1.159	Types::Serialiser serialisation protocol).
25			- reworked the documentation regarding object serialisation,
26	root	1.165	add a new OBJECT SERIALISATION section that explains th
27	root	1.159	whole process.
28	root	1.160	- new setting: allow_tags.

33	root	1.155	2.34 Thu May 23 11:30:34 CEST 2013
34			- work around bugs in perl 5.18 breaking more than 100
35			widely used modules, without a fix in sight because
36			p5pers don't care about CPAN anymore.
37	root	1.154	- when canonicalising, only allocate up to 64 hash key
38			pointers on the stack. for larger hashes, use the heap,
39			to avoid using too much stackspace.

51	root	1.149	2.31 Wed Jul 27 17:53:05 CEST 2011
52	root	1.153	- don't accumulate initial whitespace in the incremental buffer
53	root	1.149	(this can be useful to allow whitespace-keepalive on a tcp
54			connection without triggering the max_size limit).
55	root	1.148	- properly croak on some invalid inputs that are not strings
56			(e.g. undef) when trying to decode a json text (reported

76	root	1.142	- clarify floating point conversion issues a bit.
77	root	1.138	- update jpsykes csrf article url.

86			by Strobl Anton).
87	root	1.134	- output format change: indent now adds a final newline, which is
88			more expected and more true to the documentation.
89	root	1.132

96	root	1.128
97	root	1.127	2.24 Sat May 30 08:25:45 CEST 2009
98			- the incremental parser did not update its parse offset
99			pointer correctly when parsing utf8-strings (nicely
100			debugged by Martin Evans).
101			- appending a non-utf8-string to the incremental parser
102			in utf8 mode failed to upgrade the string.
103			- wording of parse error messages has been improved.

112	root	1.124	2.2311 Thu Feb 19 02:12:54 CET 2009
113	root	1.123	- add a section "JSON and ECMAscript" to explain some
114			incompatibilities between the two (problem was noted by
115			various people).
116	root	1.122	- add t/20_faihu.t.
117
118	root	1.121	2.231 Thu Nov 20 04:59:08 CET 2008
119			- work around 5.10.0 magic bugs where manipulating magic values
120			(such as $1) would permanently damage them as perl would
121			ignore the magicalness, by making a full copy of the string,
122			reported by Dmitry Karasik.
123	root	1.125	- work around spurious warnings under older perl 5.8's.

131			- same game again, broken 5.10 finds yet another assertion
132			failure, and the workaround causes additional runtime warnings.
133			Work around the next assertion AND the warning. 5.10 seriously
134			needs to adjust it's attitude against working code.
135
136	root	1.117	2.222 Sat Jul 19 06:15:34 CEST 2008
137			- you work around one -DDEBUGGING assertion bug in perl 5.10

139
140	root	1.116	2.22 Tue Jul 15 13:26:51 CEST 2008
141	root	1.115	- allow higher nesting levels in incremental parser.

147			- (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
148	root	1.112	- remove the experimental status of the incremental parser interface.
149	root	1.111	- move =encoding around again, to avoid bugs with search.cpan.org.
150			when can we finally have utf-8 in pod???
151	root	1.113	- add ->incr_reset method.
152	root	1.111
153	root	1.110	2.2 Wed Apr 16 20:37:25 CEST 2008
154	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
155	root	1.107	- make booleans mutable by creating a copy instead of handing out
156			the same scalar (reported by pasha sadri).
157	root	1.164	- added support for incremental json parsing (still EXPERIMENTAL).
158	root	1.103	- implemented and added a json_xs command line utility that can convert
159			from/to a number of serialisation formats - tell me if you need more.
160	root	1.108	- implement allow_unknown/get_allow_unknown methods.
161	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.
162	root	1.112	- moved down =encoding directive a bit, too much breaks if it's the first
163	root	1.102	pod directive :/.
164	root	1.106	- removed documentation section on other modules, it became somewhat
165			outdated and is nowadays mostly of historical interest.
166	root	1.102
167	root	1.101	2.1 Wed Mar 19 23:23:18 CET 2008
168			- update documentation here and there: add a large section
169			about utf8/latin1/ascii flags, add a security consideration
170			and extend and clarify the JSON and YAML section.
171	root	1.98	- medium speed enhancements when encoding/decoding non-ascii chars.
172	root	1.100	- minor speedup in number encoding case.
173	root	1.92	- extend and clarify the section on incompatibilities
174			between YAML and JSON.
175	root	1.95	- switch to static inline from just inline when using gcc.
176	root	1.94	- add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
177	root	1.100	- fix some issues with UV to JSON conversion of unknown impact.
178	root	1.99	- published the yahoo locals search result used in benchmarks as the
179			original url changes so comparison is impossible.
180	root	1.92
181	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
182			- INCOMPATIBLE API CHANGE: to_json and from_json have been
183			renamed to encode_json/decode_json for JSON.pm compatibility.
184			The old functions croak and might be replaced by JSON.pm
185			comaptible versions in some later release.
186
187	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
188			- this is supposed to be the first version of JSON::XS
189			compatible with version 2.0+ of the JSON module.
190			Using the JSON module as frontend to JSON::XS should be
191			as fast as using JSON::XS directly, so consider using it
192			instead.
193	root	1.88	- added get_* methods for all "simple" options.
194	root	1.89	- make JSON::XS subclassable.
195	root	1.88
196	root	1.86	1.53 Tue Nov 13 23:58:33 CET 2007
197	root	1.85	- minor doc clarifications.

199
200	root	1.84	1.52 Mon Oct 15 03:22:06 CEST 2007
201	root	1.83	- remove =encoding pod directive again, it confuses too many pod
202			parsers :/.
203
204	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
205	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
206	root	1.87	- apparently JSON::XS was used to find some bugs in the
207	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
208			the testsuite.
209			- quite a bit of doc updates/extension.
210	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
211	root	1.78
212	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
213	root	1.74	- add support for tied hashes, based on ideas and testcase by
214			Marcus Holland-Moritz.
215	root	1.75	- implemented relaxed parsing mode where some extensions are being
216			accepted. generation is still JSON-only.
217	root	1.74
218			1.44 Wed Aug 22 01:02:44 CEST 2007
219	root	1.73	- very experimental process-emulation support, slowing everything down.
220			the horribly broken perl threads are still not supported - YMMV.
221
222	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007
223			- convert big json numbers exclusively consisting of digits to NV
224			only when there is no loss of precision, otherwise to string.
225
226	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
227			- fix a crash caused by not handling missing array elements
228			(report and testcase by Jay Kuri).
229
230	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
231			- fix compilation with NDEBUG (assert side-effect),
232			affects convert_blessed only.
233	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
234			one time too often.
235	root	1.70	- catch a typical error in TO_JSON methods.
236	root	1.69	- antique-ised XS.xs again to work with outdated
237			C compilers (windows...).
238
239	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
240	root	1.63	- add convert_blessed setting.
241	root	1.56	- encode did not catch all blessed objects, encoding their
242			contents in most cases. This has been fixed by introducing
243			the allow_blessed setting.
244	root	1.65	- added filter_json_object and filter_json_single_key_object
245			settings that specify a callback to be called when
246	root	1.67	all/specific json objects are encountered.
247	root	1.59	- assume that most object keys are simple ascii words and
248			optimise this case, penalising the general case. This can
249			speed up decoding by 30% in typical cases and gives
250			a smaller and faster perl hash.
251	root	1.58	- implemented simpleminded, optional resource size checking
252			in decode_json.
253	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
254			of JSON will not have them either.
255	root	1.62	- bit the bullet and converted the very simple json object
256			into a more complex one.
257	root	1.64	- work around a bug where perl wrongly claims an integer
258			is not an integer.
259	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
260			and similar modules can resolve the overloading when thawing.
261	root	1.56
262	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
263	root	1.54	- make JSON::XS::true and false special overloaded objects
264			and return those instead of 1 and 0 for those json atoms
265			(JSON::PP compatibility is NOT achieved yet).
266			- add JSON::XS::is_bool predicate to test for those special
267			values.
268	root	1.52	- add a reference to
269			http://jpsykes.com/47/practical-csrf-and-json-security.
270	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
271			Also try to be more compatible with slightly older versions,
272	root	1.54	which are not recommended (because they are buggy).
273	root	1.52
274	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
275	root	1.49	- added informative section on JSON-as-YAML.
276	root	1.51	- get rid of some c99-isms again.
277	root	1.50	- localise dec->cur in decode_str, speeding up
278			string decoding considerably (>15% on my amd64 + gcc).
279			- increased SHORT_STRING_LEN to 16kb: stack space is
280			usually plenty, and this actually saves memory
281	root	1.51	when !shrinking as short strings will fit perfectly.
282	root	1.49
283	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
284	root	1.46	- greatly improved small integer encoding and decoding speed.
285			- implement a number of µ-optimisations.
286	root	1.47	- updated benchmarks.
287	root	1.46
288	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
289	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
290			the required macros.
291	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
292	root	1.42
293	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
294	root	1.47	- character offset reported for trailing garbage was random.
295	root	1.41
296	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
297			- decode did not work with magical scalars (doh!).
298	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
299			of unicode.
300	root	1.39	- flag trailing garbage as error.
301			- new decode_prefix method that returns the number
302			of characters consumed by a decode.
303	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
304			as pointed out by Glenn Linderman.
305			- fixed typoe reported by YAMASHINA Hio.
306	root	1.34
307	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
308			- properly 0-terminate sv's returned by encode to help
309			C libraries that expect that 0 to be there.
310	root	1.31	- partially "port" JSON from C to microsofts fucking broken
311			pseudo-C. They should be burned to the ground for pissing
312			on standards. And I should be stoned for even trying to
313	root	1.32	support this filthy excuse for a c compiler.
314	root	1.6
315	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
316	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
317	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
318			leading to segfaults.
319	root	1.30	- further reduced default nesting depth to 512 due to the test
320			failure by that anonymous "chris" whose e-mail address seems
321			to be impossible to get. Tests on other freebsd systems indicate
322			that this is likely a problem in his/her configuration and not this
323			module.
324			- renamed json => JSON in error messages.
325			- corrected the character offset in some error messages.
326	root	1.28
327	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
328			- do not segfault when from_json/decode gets passed
329			a non-string object (reported by Florian Ragwitz).
330			This has no effect on normal operation.
331
332	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
333			- the long awaited (by me) 1.0 version.
334			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
335			true and false.
336	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
337	root	1.25	- improve testsuite.
338	root	1.26	- halve the default nesting depth limit, to hopefully make it
339	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
340			send me his report, so I cannot ask about the stack limit on fbsd).
341	root	1.24
342	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
343	root	1.21	- fix a memleak when decoding hashes.
344	root	1.20	- export jsonToBj and objToJson as aliases

357			lots of \u escapes.
358	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
359	root	1.16
360	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
361	root	1.14	- added the UTF-16 encoding example hinted at in previous
362			versions.
363			- minor documentation fixes.
364	root	1.15	- fix a bug in and optimise canonicalising fastpath
365			(reported by Craig Manley).
366			- remove a subtest that breaks with bleadperl (reported
367			by Andreas König).
368	root	1.14
369	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
370	root	1.12	- documentation updates.

373	root	1.12
374	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
375	root	1.5	- remove spurious PApp::Util reference (John McNamara).
376			- adapted lots of tests from other json modules
377			(idea by Chris Carline).
378	root	1.9	- documented mapping from json to perl and vice versa.
379	root	1.11	- improved the documentation by adding more examples.
380	root	1.5	- added short escaping forms, reducing the created
381			json texts a bit.
382			- added shrink flag.
