Revision history for Perl extension JSON::XS

TODO: -f eval
        - applied patch by DaTa for Data::Dumper support in json_xs.
        - added -t dump support to json_xs, using Data::Dump.

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.
 
0.01  Thu Mar 22 06:08:12 CET 2007
        - original version; cloned from Convert-Scalar

66	root	1.120	2.23 Mon Sep 29 05:08:29 CEST 2008
67			- fix a compilation problem when perl is not using char * as, well,
68			char *.
69	root	1.119	- use PL_hexdigit in favour of rolling our own.
70
71	root	1.118	2.2222 Sun Jul 20 18:49:00 CEST 2008
72			- same game again, broken 5.10 finds yet another assertion
73			failure, and the workaround causes additional runtime warnings.
74			Work around the next assertion AND the warning. 5.10 seriously
75			needs to adjust it's attitude against working code.
76
77	root	1.117	2.222 Sat Jul 19 06:15:34 CEST 2008
78			- you work around one -DDEBUGGING assertion bug in perl 5.10
79			just to hit the next one. work around this one, too.
80
81	root	1.116	2.22 Tue Jul 15 13:26:51 CEST 2008
82	root	1.115	- allow higher nesting levels in incremental parser.
83			- error out earlier in some cases in the incremental parser
84			(as suggested by Yuval Kogman).
85			- improve incr-parser test (Yuval Kogman).
86
87	root	1.114	2.21 Tue Jun 3 08:43:23 CEST 2008
88			- (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
89	root	1.112	- remove the experimental status of the incremental parser interface.
90	root	1.111	- move =encoding around again, to avoid bugs with search.cpan.org.
91			when can we finally have utf-8 in pod???
92	root	1.113	- add ->incr_reset method.
93	root	1.111
94	root	1.110	2.2 Wed Apr 16 20:37:25 CEST 2008
95	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
96	root	1.107	- make booleans mutable by creating a copy instead of handing out
97			the same scalar (reported by pasha sadri).
98	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
99	root	1.103	- implemented and added a json_xs command line utility that can convert
100			from/to a number of serialisation formats - tell me if you need more.
101	root	1.108	- implement allow_unknown/get_allow_unknown methods.
102	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.
103	root	1.112	- moved down =encoding directive a bit, too much breaks if it's the first
104	root	1.102	pod directive :/.
105	root	1.106	- removed documentation section on other modules, it became somewhat
106			outdated and is nowadays mostly of historical interest.
107	root	1.102
108	root	1.101	2.1 Wed Mar 19 23:23:18 CET 2008
109			- update documentation here and there: add a large section
110			about utf8/latin1/ascii flags, add a security consideration
111			and extend and clarify the JSON and YAML section.
112	root	1.98	- medium speed enhancements when encoding/decoding non-ascii chars.
113	root	1.100	- minor speedup in number encoding case.
114	root	1.92	- extend and clarify the section on incompatibilities
115			between YAML and JSON.
116	root	1.95	- switch to static inline from just inline when using gcc.
117	root	1.94	- add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
118	root	1.100	- fix some issues with UV to JSON conversion of unknown impact.
119	root	1.99	- published the yahoo locals search result used in benchmarks as the
120			original url changes so comparison is impossible.
121	root	1.92
122	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
123			- INCOMPATIBLE API CHANGE: to_json and from_json have been
124			renamed to encode_json/decode_json for JSON.pm compatibility.
125			The old functions croak and might be replaced by JSON.pm
126			comaptible versions in some later release.
127
128	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
129			- this is supposed to be the first version of JSON::XS
130			compatible with version 2.0+ of the JSON module.
131			Using the JSON module as frontend to JSON::XS should be
132			as fast as using JSON::XS directly, so consider using it
133			instead.
134	root	1.88	- added get_* methods for all "simple" options.
135	root	1.89	- make JSON::XS subclassable.
136	root	1.88
137	root	1.86	1.53 Tue Nov 13 23:58:33 CET 2007
138	root	1.85	- minor doc clarifications.

140
141	root	1.84	1.52 Mon Oct 15 03:22:06 CEST 2007
142	root	1.83	- remove =encoding pod directive again, it confuses too many pod
143			parsers :/.
144
145	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
146	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
147	root	1.87	- apparently JSON::XS was used to find some bugs in the
148	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
149			the testsuite.
150			- quite a bit of doc updates/extension.
151	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
152	root	1.78
153	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
154	root	1.74	- add support for tied hashes, based on ideas and testcase by
155			Marcus Holland-Moritz.
156	root	1.75	- implemented relaxed parsing mode where some extensions are being
157			accepted. generation is still JSON-only.
158	root	1.74
159			1.44 Wed Aug 22 01:02:44 CEST 2007
160	root	1.73	- very experimental process-emulation support, slowing everything down.
161			the horribly broken perl threads are still not supported - YMMV.
162
163	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007
164			- convert big json numbers exclusively consisting of digits to NV
165			only when there is no loss of precision, otherwise to string.
166
167	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
168			- fix a crash caused by not handling missing array elements
169			(report and testcase by Jay Kuri).
170
171	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
172			- fix compilation with NDEBUG (assert side-effect),
173			affects convert_blessed only.
174	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
175			one time too often.
176	root	1.70	- catch a typical error in TO_JSON methods.
177	root	1.69	- antique-ised XS.xs again to work with outdated
178			C compilers (windows...).
179
180	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
181	root	1.63	- add convert_blessed setting.
182	root	1.56	- encode did not catch all blessed objects, encoding their
183			contents in most cases. This has been fixed by introducing
184			the allow_blessed setting.
185	root	1.65	- added filter_json_object and filter_json_single_key_object
186			settings that specify a callback to be called when
187	root	1.67	all/specific json objects are encountered.
188	root	1.59	- assume that most object keys are simple ascii words and
189			optimise this case, penalising the general case. This can
190			speed up decoding by 30% in typical cases and gives
191			a smaller and faster perl hash.
192	root	1.58	- implemented simpleminded, optional resource size checking
193			in decode_json.
194	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
195			of JSON will not have them either.
196	root	1.62	- bit the bullet and converted the very simple json object
197			into a more complex one.
198	root	1.64	- work around a bug where perl wrongly claims an integer
199			is not an integer.
200	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
201			and similar modules can resolve the overloading when thawing.
202	root	1.56
203	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
204	root	1.54	- make JSON::XS::true and false special overloaded objects
205			and return those instead of 1 and 0 for those json atoms
206			(JSON::PP compatibility is NOT achieved yet).
207			- add JSON::XS::is_bool predicate to test for those special
208			values.
209	root	1.52	- add a reference to
210			http://jpsykes.com/47/practical-csrf-and-json-security.
211	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
212			Also try to be more compatible with slightly older versions,
213	root	1.54	which are not recommended (because they are buggy).
214	root	1.52
215	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
216	root	1.49	- added informative section on JSON-as-YAML.
217	root	1.51	- get rid of some c99-isms again.
218	root	1.50	- localise dec->cur in decode_str, speeding up
219			string decoding considerably (>15% on my amd64 + gcc).
220			- increased SHORT_STRING_LEN to 16kb: stack space is
221			usually plenty, and this actually saves memory
222	root	1.51	when !shrinking as short strings will fit perfectly.
223	root	1.49
224	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
225	root	1.46	- greatly improved small integer encoding and decoding speed.
226			- implement a number of µ-optimisations.
227	root	1.47	- updated benchmarks.
228	root	1.46
229	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
230	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
231			the required macros.
232	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
233	root	1.42
234	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
235	root	1.47	- character offset reported for trailing garbage was random.
236	root	1.41
237	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
238			- decode did not work with magical scalars (doh!).
239	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
240			of unicode.
241	root	1.39	- flag trailing garbage as error.
242			- new decode_prefix method that returns the number
243			of characters consumed by a decode.
244	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
245			as pointed out by Glenn Linderman.
246			- fixed typoe reported by YAMASHINA Hio.
247	root	1.34
248	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
249			- properly 0-terminate sv's returned by encode to help
250			C libraries that expect that 0 to be there.
251	root	1.31	- partially "port" JSON from C to microsofts fucking broken
252			pseudo-C. They should be burned to the ground for pissing
253			on standards. And I should be stoned for even trying to
254	root	1.32	support this filthy excuse for a c compiler.
255	root	1.6
256	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
257	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
258	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
259			leading to segfaults.
260	root	1.30	- further reduced default nesting depth to 512 due to the test
261			failure by that anonymous "chris" whose e-mail address seems
262			to be impossible to get. Tests on other freebsd systems indicate
263			that this is likely a problem in his/her configuration and not this
264			module.
265			- renamed json => JSON in error messages.
266			- corrected the character offset in some error messages.
267	root	1.28
268	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
269			- do not segfault when from_json/decode gets passed
270			a non-string object (reported by Florian Ragwitz).
271			This has no effect on normal operation.
272
273	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
274			- the long awaited (by me) 1.0 version.
275			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
276			true and false.
277	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
278	root	1.25	- improve testsuite.
279	root	1.26	- halve the default nesting depth limit, to hopefully make it
280	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
281			send me his report, so I cannot ask about the stack limit on fbsd).
282	root	1.24
283	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
284	root	1.21	- fix a memleak when decoding hashes.
285	root	1.20	- export jsonToBj and objToJson as aliases
286			to to_json and from_json, to reduce incompatibilities
287			between JSON/JSON::PC and JSON::XS. (experimental).
288	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
289			- added a security considerations sections.
290	root	1.20
291	root	1.19	0.7 Sun Mar 25 01:46:30 CET 2007
292	root	1.16	- code cleanup.
293			- fix a memory overflow bug when indenting.
294			- pretty-printing now up to 15% faster.
295			- improve decoding speed of strings by
296			up to 50% by specialcasing short strings.
297			- further decoding speedups for strings using
298			lots of \u escapes.
299	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
300	root	1.16
301	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
302	root	1.14	- added the UTF-16 encoding example hinted at in previous
303			versions.
304			- minor documentation fixes.
305	root	1.15	- fix a bug in and optimise canonicalising fastpath
306			(reported by Craig Manley).
307			- remove a subtest that breaks with bleadperl (reported
308			by Andreas König).
309	root	1.14
310	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
311	root	1.12	- documentation updates.
312	root	1.13	- do some casting to hopefully fix Andreas' problem.
313			- nuke bogus json rpc stuff.
314	root	1.12
315	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
316	root	1.5	- remove spurious PApp::Util reference (John McNamara).
317			- adapted lots of tests from other json modules
318			(idea by Chris Carline).
319	root	1.9	- documented mapping from json to perl and vice versa.
320	root	1.11	- improved the documentation by adding more examples.
321	root	1.5	- added short escaping forms, reducing the created
322			json texts a bit.
323			- added shrink flag.
324			- when flag methods are called without enable argument
325			they will by default enable their flag.
326			- considerably improved string encoding speed (at least
327			with gcc 4).
328	root	1.7	- added a test that covers lots of different characters.
329			- clarified some error messages.
330			- error messages now use correct character offset
331			with F_UTF8.
332	root	1.8	- improve the "no bytes" and "no warnings" hacks in
333			case the called functions do... stuff.
334	root	1.9	- croak when encoding to ascii and an out-of-range
335			(non-unicode) codepoint is encountered.
336	root	1.4
337	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
338	root	1.109	- the "could not sleep without debugging release".
339	root	1.3	it should basically work now, with many bugs as
340			no production tests have been run yet.
341			- added more testcases.
342			- the expected shitload of bugfixes.
343			- handle utf8 flag correctly in decode.
344			- fix segfault in decoder.
345			- utf8n_to_uvuni sets retlen to -1, but retlen is an
346			unsigned types (argh).
347			- fix decoding of utf-8 strings.
348			- improved error diagnostics.
349			- fix decoding of 'null'.
350			- fix parsing of empty array/hashes
351			- silence warnings when we prepare the croak message.
352
353	root	1.2	0.1 Thu Mar 22 22:13:43 CET 2007

355			the namespace.
356	root	1.1
357			0.01 Thu Mar 22 06:08:12 CET 2007
