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.
TODO: http://stevehanov.ca/blog/index.php?id=104 compression

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

53			more expected and more true to the documentation.
54	root	1.132
55	root	1.131	2.25 Sat Aug 8 12:04:41 CEST 2009

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

84			- work around 5.10.0 magic bugs where manipulating magic values

94
95	root	1.118	2.2222 Sun Jul 20 18:49:00 CEST 2008
96			- same game again, broken 5.10 finds yet another assertion
97			failure, and the workaround causes additional runtime warnings.
98			Work around the next assertion AND the warning. 5.10 seriously
99			needs to adjust it's attitude against working code.
100
101	root	1.117	2.222 Sat Jul 19 06:15:34 CEST 2008

118	root	1.110	2.2 Wed Apr 16 20:37:25 CEST 2008
119	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
120	root	1.107	- make booleans mutable by creating a copy instead of handing out
121			the same scalar (reported by pasha sadri).
122	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
123	root	1.103	- implemented and added a json_xs command line utility that can convert

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130			outdated and is nowadays mostly of historical interest.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

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

164
165	root	1.84	1.52 Mon Oct 15 03:22:06 CEST 2007
166	root	1.83	- remove =encoding pod directive again, it confuses too many pod
167			parsers :/.
168
169	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
170	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
171	root	1.87	- apparently JSON::XS was used to find some bugs in the
172	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
173			the testsuite.
174			- quite a bit of doc updates/extension.
175	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
176	root	1.78
177	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
178	root	1.74	- add support for tied hashes, based on ideas and testcase by
179			Marcus Holland-Moritz.
180	root	1.75	- implemented relaxed parsing mode where some extensions are being
181			accepted. generation is still JSON-only.
182	root	1.74
183			1.44 Wed Aug 22 01:02:44 CEST 2007
184	root	1.73	- very experimental process-emulation support, slowing everything down.
185			the horribly broken perl threads are still not supported - YMMV.
186
187	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007
188			- convert big json numbers exclusively consisting of digits to NV
189			only when there is no loss of precision, otherwise to string.
190
191	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
192			- fix a crash caused by not handling missing array elements
193			(report and testcase by Jay Kuri).
194
195	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
196			- fix compilation with NDEBUG (assert side-effect),
197			affects convert_blessed only.
198	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
199			one time too often.
200	root	1.70	- catch a typical error in TO_JSON methods.
201	root	1.69	- antique-ised XS.xs again to work with outdated
202			C compilers (windows...).
203
204	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
205	root	1.63	- add convert_blessed setting.
206	root	1.56	- encode did not catch all blessed objects, encoding their
207			contents in most cases. This has been fixed by introducing
208			the allow_blessed setting.
209	root	1.65	- added filter_json_object and filter_json_single_key_object
210			settings that specify a callback to be called when
211	root	1.67	all/specific json objects are encountered.
212	root	1.59	- assume that most object keys are simple ascii words and
213			optimise this case, penalising the general case. This can
214			speed up decoding by 30% in typical cases and gives
215			a smaller and faster perl hash.
216	root	1.58	- implemented simpleminded, optional resource size checking
217			in decode_json.
218	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
219			of JSON will not have them either.
220	root	1.62	- bit the bullet and converted the very simple json object
221			into a more complex one.
222	root	1.64	- work around a bug where perl wrongly claims an integer
223			is not an integer.
224	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
225			and similar modules can resolve the overloading when thawing.
226	root	1.56
227	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
228	root	1.54	- make JSON::XS::true and false special overloaded objects
229			and return those instead of 1 and 0 for those json atoms
230			(JSON::PP compatibility is NOT achieved yet).
231			- add JSON::XS::is_bool predicate to test for those special
232			values.
233	root	1.52	- add a reference to
234			http://jpsykes.com/47/practical-csrf-and-json-security.
235	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
236			Also try to be more compatible with slightly older versions,
237	root	1.54	which are not recommended (because they are buggy).
238	root	1.52
239	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
240	root	1.49	- added informative section on JSON-as-YAML.
241	root	1.51	- get rid of some c99-isms again.
242	root	1.50	- localise dec->cur in decode_str, speeding up
243			string decoding considerably (>15% on my amd64 + gcc).
244			- increased SHORT_STRING_LEN to 16kb: stack space is
245			usually plenty, and this actually saves memory
246	root	1.51	when !shrinking as short strings will fit perfectly.
247	root	1.49
248	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
249	root	1.46	- greatly improved small integer encoding and decoding speed.
250			- implement a number of µ-optimisations.
251	root	1.47	- updated benchmarks.
252	root	1.46
253	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
254	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
255			the required macros.
256	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
257	root	1.42
258	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
259	root	1.47	- character offset reported for trailing garbage was random.
260	root	1.41
261	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
262			- decode did not work with magical scalars (doh!).
263	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
264			of unicode.
265	root	1.39	- flag trailing garbage as error.
266			- new decode_prefix method that returns the number
267			of characters consumed by a decode.
268	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
269			as pointed out by Glenn Linderman.
270			- fixed typoe reported by YAMASHINA Hio.
271	root	1.34
272	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
273			- properly 0-terminate sv's returned by encode to help
274			C libraries that expect that 0 to be there.
275	root	1.31	- partially "port" JSON from C to microsofts fucking broken
276			pseudo-C. They should be burned to the ground for pissing
277			on standards. And I should be stoned for even trying to
278	root	1.32	support this filthy excuse for a c compiler.
279	root	1.6
280	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
281	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
282	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
283			leading to segfaults.
284	root	1.30	- further reduced default nesting depth to 512 due to the test
285			failure by that anonymous "chris" whose e-mail address seems
286			to be impossible to get. Tests on other freebsd systems indicate
287			that this is likely a problem in his/her configuration and not this
288			module.
289			- renamed json => JSON in error messages.
290			- corrected the character offset in some error messages.
291	root	1.28
292	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
293			- do not segfault when from_json/decode gets passed
294			a non-string object (reported by Florian Ragwitz).
295			This has no effect on normal operation.
296
297	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
298			- the long awaited (by me) 1.0 version.
299			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
300			true and false.
301	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
302	root	1.25	- improve testsuite.
303	root	1.26	- halve the default nesting depth limit, to hopefully make it
304	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
305			send me his report, so I cannot ask about the stack limit on fbsd).
306	root	1.24
307	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
308	root	1.21	- fix a memleak when decoding hashes.
309	root	1.20	- export jsonToBj and objToJson as aliases
310			to to_json and from_json, to reduce incompatibilities
311			between JSON/JSON::PC and JSON::XS. (experimental).
312	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
313			- added a security considerations sections.

320			up to 50% by specialcasing short strings.
321			- further decoding speedups for strings using
322			lots of \u escapes.
323	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
324	root	1.16

326	root	1.14	- added the UTF-16 encoding example hinted at in previous
327			versions.
328			- minor documentation fixes.
329	root	1.15	- fix a bug in and optimise canonicalising fastpath
330			(reported by Craig Manley).
331			- remove a subtest that breaks with bleadperl (reported
332			by Andreas König).
333	root	1.14
334	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
335	root	1.12	- documentation updates.

338	root	1.12
339	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
340	root	1.5	- remove spurious PApp::Util reference (John McNamara).
341			- adapted lots of tests from other json modules
342			(idea by Chris Carline).
343	root	1.9	- documented mapping from json to perl and vice versa.
344	root	1.11	- improved the documentation by adding more examples.
345	root	1.5	- added short escaping forms, reducing the created
346			json texts a bit.
347			- added shrink flag.
348			- when flag methods are called without enable argument
349			they will by default enable their flag.
350			- considerably improved string encoding speed (at least
351			with gcc 4).
352	root	1.7	- added a test that covers lots of different characters.
353			- clarified some error messages.
354			- error messages now use correct character offset
355			with F_UTF8.
356	root	1.8	- improve the "no bytes" and "no warnings" hacks in
357			case the called functions do... stuff.
358	root	1.9	- croak when encoding to ascii and an out-of-range
359			(non-unicode) codepoint is encountered.
360	root	1.4
361	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
362	root	1.109	- the "could not sleep without debugging release".
363	root	1.3	it should basically work now, with many bugs as
364			no production tests have been run yet.

366			- the expected shitload of bugfixes.
367			- handle utf8 flag correctly in decode.
368			- fix segfault in decoder.

372			- improved error diagnostics.
373			- fix decoding of 'null'.
374			- fix parsing of empty array/hashes
