Revision history for Perl extension JSON::XS

TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)
TODO: maybe avoid the reblessing and better support readonly objects.

        - 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.
 
0.01  Thu Mar 22 06:08:12 CET 2007

48	root	1.134	- output format change: indent now adds a final newline, which is
49			more expected and more true to the documentation.
50	root	1.132
51	root	1.131	2.25 Sat Aug 8 12:04:41 CEST 2009

59			- the incremental parser did not update its parse offset
60			pointer correctly when parsing utf8-strings (nicely
61			debugged by Martin Evans).
62			- appending a non-utf8-string to the incremental parser
63			in utf8 mode failed to upgrade the string.

80			- work around 5.10.0 magic bugs where manipulating magic values

90
91	root	1.118	2.2222 Sun Jul 20 18:49:00 CEST 2008
92			- same game again, broken 5.10 finds yet another assertion
93			failure, and the workaround causes additional runtime warnings.
94			Work around the next assertion AND the warning. 5.10 seriously
95			needs to adjust it's attitude against working code.

115	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
116	root	1.107	- make booleans mutable by creating a copy instead of handing out
117			the same scalar (reported by pasha sadri).
118	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
119	root	1.103	- implemented and added a json_xs command line utility that can convert

121	root	1.108	- implement allow_unknown/get_allow_unknown methods.
122	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.
123	root	1.112	- moved down =encoding directive a bit, too much breaks if it's the first
124	root	1.102	pod directive :/.
125	root	1.106	- removed documentation section on other modules, it became somewhat
126			outdated and is nowadays mostly of historical interest.
127	root	1.102
128	root	1.101	2.1 Wed Mar 19 23:23:18 CET 2008

138	root	1.100	- fix some issues with UV to JSON conversion of unknown impact.
139	root	1.99	- published the yahoo locals search result used in benchmarks as the
140			original url changes so comparison is impossible.
141	root	1.92
142	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
143			- INCOMPATIBLE API CHANGE: to_json and from_json have been
144			renamed to encode_json/decode_json for JSON.pm compatibility.
145			The old functions croak and might be replaced by JSON.pm
146			comaptible versions in some later release.
147
148	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
149			- this is supposed to be the first version of JSON::XS
150			compatible with version 2.0+ of the JSON module.
151			Using the JSON module as frontend to JSON::XS should be
152			as fast as using JSON::XS directly, so consider using it
153			instead.
154	root	1.88	- added get_* methods for all "simple" options.
155	root	1.89	- make JSON::XS subclassable.
156	root	1.88

164
165	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
166	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
167	root	1.87	- apparently JSON::XS was used to find some bugs in the
168	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
169			the testsuite.
170			- quite a bit of doc updates/extension.
171	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
172	root	1.78
173	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
174	root	1.74	- add support for tied hashes, based on ideas and testcase by
175			Marcus Holland-Moritz.
176	root	1.75	- implemented relaxed parsing mode where some extensions are being
177			accepted. generation is still JSON-only.
178	root	1.74
179			1.44 Wed Aug 22 01:02:44 CEST 2007

186
187	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007

190
191	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
192			- fix compilation with NDEBUG (assert side-effect),
193			affects convert_blessed only.
194	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
195			one time too often.
196	root	1.70	- catch a typical error in TO_JSON methods.
197	root	1.69	- antique-ised XS.xs again to work with outdated
198			C compilers (windows...).
199
200	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
201	root	1.63	- add convert_blessed setting.
202	root	1.56	- encode did not catch all blessed objects, encoding their
203			contents in most cases. This has been fixed by introducing
204			the allow_blessed setting.
205	root	1.65	- added filter_json_object and filter_json_single_key_object
206			settings that specify a callback to be called when
207	root	1.67	all/specific json objects are encountered.
208	root	1.59	- assume that most object keys are simple ascii words and
209			optimise this case, penalising the general case. This can
210			speed up decoding by 30% in typical cases and gives
211			a smaller and faster perl hash.
212	root	1.58	- implemented simpleminded, optional resource size checking
213			in decode_json.
214	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
215			of JSON will not have them either.
216	root	1.62	- bit the bullet and converted the very simple json object
217			into a more complex one.
218	root	1.64	- work around a bug where perl wrongly claims an integer
219			is not an integer.
220	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
221			and similar modules can resolve the overloading when thawing.
222	root	1.56
223	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
224	root	1.54	- make JSON::XS::true and false special overloaded objects
225			and return those instead of 1 and 0 for those json atoms
226			(JSON::PP compatibility is NOT achieved yet).
227			- add JSON::XS::is_bool predicate to test for those special
228			values.
229	root	1.52	- add a reference to
230			http://jpsykes.com/47/practical-csrf-and-json-security.
231	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
232			Also try to be more compatible with slightly older versions,
233	root	1.54	which are not recommended (because they are buggy).
234	root	1.52
235	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
236	root	1.49	- added informative section on JSON-as-YAML.
237	root	1.51	- get rid of some c99-isms again.
238	root	1.50	- localise dec->cur in decode_str, speeding up
239			string decoding considerably (>15% on my amd64 + gcc).
240			- increased SHORT_STRING_LEN to 16kb: stack space is
241			usually plenty, and this actually saves memory
242	root	1.51	when !shrinking as short strings will fit perfectly.
243	root	1.49
244	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
245	root	1.46	- greatly improved small integer encoding and decoding speed.

248	root	1.46
249	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
250	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
251			the required macros.
252	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
253	root	1.42
254	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
255	root	1.47	- character offset reported for trailing garbage was random.
256	root	1.41
257	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
258			- decode did not work with magical scalars (doh!).
259	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
260			of unicode.
261	root	1.39	- flag trailing garbage as error.
262			- new decode_prefix method that returns the number
263			of characters consumed by a decode.
264	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
265			as pointed out by Glenn Linderman.
266			- fixed typoe reported by YAMASHINA Hio.
267	root	1.34
268	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
269			- properly 0-terminate sv's returned by encode to help
270			C libraries that expect that 0 to be there.
271	root	1.31	- partially "port" JSON from C to microsofts fucking broken
272			pseudo-C. They should be burned to the ground for pissing
273			on standards. And I should be stoned for even trying to
274	root	1.32	support this filthy excuse for a c compiler.
275	root	1.6
276	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
277	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
278	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
279			leading to segfaults.
280	root	1.30	- further reduced default nesting depth to 512 due to the test
281			failure by that anonymous "chris" whose e-mail address seems
282			to be impossible to get. Tests on other freebsd systems indicate
283			that this is likely a problem in his/her configuration and not this
284			module.
285			- renamed json => JSON in error messages.
286			- corrected the character offset in some error messages.
287	root	1.28
288	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
289			- do not segfault when from_json/decode gets passed
290			a non-string object (reported by Florian Ragwitz).
291			This has no effect on normal operation.
292
293	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
294			- the long awaited (by me) 1.0 version.
295			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
296			true and false.
297	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
298	root	1.25	- improve testsuite.
299	root	1.26	- halve the default nesting depth limit, to hopefully make it
300	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
301			send me his report, so I cannot ask about the stack limit on fbsd).
302	root	1.24
303	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
304	root	1.21	- fix a memleak when decoding hashes.
305	root	1.20	- export jsonToBj and objToJson as aliases
306			to to_json and from_json, to reduce incompatibilities
307			between JSON/JSON::PC and JSON::XS. (experimental).
308	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
309			- added a security considerations sections.

316			up to 50% by specialcasing short strings.
317			- further decoding speedups for strings using
318			lots of \u escapes.

320	root	1.16
321	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
322	root	1.14	- added the UTF-16 encoding example hinted at in previous
323			versions.
324			- minor documentation fixes.
325	root	1.15	- fix a bug in and optimise canonicalising fastpath
326			(reported by Craig Manley).
327			- remove a subtest that breaks with bleadperl (reported
328			by Andreas König).
329	root	1.14
330	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
331	root	1.12	- documentation updates.

335	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
336	root	1.5	- remove spurious PApp::Util reference (John McNamara).
337			- adapted lots of tests from other json modules
338			(idea by Chris Carline).
339	root	1.9	- documented mapping from json to perl and vice versa.
340	root	1.11	- improved the documentation by adding more examples.
341	root	1.5	- added short escaping forms, reducing the created
342			json texts a bit.
343			- added shrink flag.
344			- when flag methods are called without enable argument
345			they will by default enable their flag.
346			- considerably improved string encoding speed (at least
347			with gcc 4).
348	root	1.7	- added a test that covers lots of different characters.
349			- clarified some error messages.
350			- error messages now use correct character offset
351			with F_UTF8.
352	root	1.8	- improve the "no bytes" and "no warnings" hacks in
353			case the called functions do... stuff.
354	root	1.9	- croak when encoding to ascii and an out-of-range
355			(non-unicode) codepoint is encountered.
356	root	1.4
357	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
358	root	1.109	- the "could not sleep without debugging release".
359	root	1.3	it should basically work now, with many bugs as
360			no production tests have been run yet.

362			- the expected shitload of bugfixes.
363			- handle utf8 flag correctly in decode.
364			- fix segfault in decoder.

368			- improved error diagnostics.
369			- fix decoding of 'null'.
