Revision history for Perl extension JSON::XS

        - 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).
        - update jpsykes csrf article url.

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

78	root	1.111	- move =encoding around again, to avoid bugs with search.cpan.org.
79			when can we finally have utf-8 in pod???
80	root	1.113	- add ->incr_reset method.
81	root	1.111
82	root	1.110	2.2 Wed Apr 16 20:37:25 CEST 2008
83	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
84	root	1.107	- make booleans mutable by creating a copy instead of handing out
85			the same scalar (reported by pasha sadri).
86	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
87	root	1.103	- implemented and added a json_xs command line utility that can convert
88			from/to a number of serialisation formats - tell me if you need more.
89	root	1.108	- implement allow_unknown/get_allow_unknown methods.
90	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.
91	root	1.112	- moved down =encoding directive a bit, too much breaks if it's the first
92	root	1.102	pod directive :/.
93	root	1.106	- removed documentation section on other modules, it became somewhat
94			outdated and is nowadays mostly of historical interest.
95	root	1.102
96	root	1.101	2.1 Wed Mar 19 23:23:18 CET 2008
97			- update documentation here and there: add a large section
98			about utf8/latin1/ascii flags, add a security consideration
99			and extend and clarify the JSON and YAML section.
100	root	1.98	- medium speed enhancements when encoding/decoding non-ascii chars.
101	root	1.100	- minor speedup in number encoding case.
102	root	1.92	- extend and clarify the section on incompatibilities
103			between YAML and JSON.
104	root	1.95	- switch to static inline from just inline when using gcc.
105	root	1.94	- add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
106	root	1.100	- fix some issues with UV to JSON conversion of unknown impact.
107	root	1.99	- published the yahoo locals search result used in benchmarks as the
108			original url changes so comparison is impossible.
109	root	1.92
110	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
111			- INCOMPATIBLE API CHANGE: to_json and from_json have been
112			renamed to encode_json/decode_json for JSON.pm compatibility.
113			The old functions croak and might be replaced by JSON.pm
114			comaptible versions in some later release.
115
116	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
117			- this is supposed to be the first version of JSON::XS
118			compatible with version 2.0+ of the JSON module.
119			Using the JSON module as frontend to JSON::XS should be
120			as fast as using JSON::XS directly, so consider using it
121			instead.
122	root	1.88	- added get_* methods for all "simple" options.
123	root	1.89	- make JSON::XS subclassable.
124	root	1.88
125	root	1.86	1.53 Tue Nov 13 23:58:33 CET 2007
126	root	1.85	- minor doc clarifications.
127			- fixed many doc typos (patch by Thomas L. Shinnick).
128
129	root	1.84	1.52 Mon Oct 15 03:22:06 CEST 2007
130	root	1.83	- remove =encoding pod directive again, it confuses too many pod
131			parsers :/.
132
133	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
134	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
135	root	1.87	- apparently JSON::XS was used to find some bugs in the
136	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
137			the testsuite.
138			- quite a bit of doc updates/extension.
139	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
140	root	1.78
141	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
142	root	1.74	- add support for tied hashes, based on ideas and testcase by
143			Marcus Holland-Moritz.
144	root	1.75	- implemented relaxed parsing mode where some extensions are being
145			accepted. generation is still JSON-only.
146	root	1.74
147			1.44 Wed Aug 22 01:02:44 CEST 2007
148	root	1.73	- very experimental process-emulation support, slowing everything down.
149			the horribly broken perl threads are still not supported - YMMV.
150
151	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007
152			- convert big json numbers exclusively consisting of digits to NV
153			only when there is no loss of precision, otherwise to string.
154
155	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
156			- fix a crash caused by not handling missing array elements
157			(report and testcase by Jay Kuri).
158
159	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
160			- fix compilation with NDEBUG (assert side-effect),
161			affects convert_blessed only.
162	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
163			one time too often.
164	root	1.70	- catch a typical error in TO_JSON methods.
165	root	1.69	- antique-ised XS.xs again to work with outdated
166			C compilers (windows...).
167
168	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
169	root	1.63	- add convert_blessed setting.
170	root	1.56	- encode did not catch all blessed objects, encoding their
171			contents in most cases. This has been fixed by introducing
172			the allow_blessed setting.
173	root	1.65	- added filter_json_object and filter_json_single_key_object
174			settings that specify a callback to be called when
175	root	1.67	all/specific json objects are encountered.
176	root	1.59	- assume that most object keys are simple ascii words and
177			optimise this case, penalising the general case. This can
178			speed up decoding by 30% in typical cases and gives
179			a smaller and faster perl hash.
180	root	1.58	- implemented simpleminded, optional resource size checking
181			in decode_json.
182	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
183			of JSON will not have them either.
184	root	1.62	- bit the bullet and converted the very simple json object
185			into a more complex one.
186	root	1.64	- work around a bug where perl wrongly claims an integer
187			is not an integer.
188	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
189			and similar modules can resolve the overloading when thawing.
190	root	1.56
191	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
192	root	1.54	- make JSON::XS::true and false special overloaded objects
193			and return those instead of 1 and 0 for those json atoms
194			(JSON::PP compatibility is NOT achieved yet).
195			- add JSON::XS::is_bool predicate to test for those special
196			values.
197	root	1.52	- add a reference to
198			http://jpsykes.com/47/practical-csrf-and-json-security.
199	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
200			Also try to be more compatible with slightly older versions,
201	root	1.54	which are not recommended (because they are buggy).
202	root	1.52
203	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
204	root	1.49	- added informative section on JSON-as-YAML.
205	root	1.51	- get rid of some c99-isms again.
206	root	1.50	- localise dec->cur in decode_str, speeding up
207			string decoding considerably (>15% on my amd64 + gcc).
208			- increased SHORT_STRING_LEN to 16kb: stack space is
209			usually plenty, and this actually saves memory
210	root	1.51	when !shrinking as short strings will fit perfectly.
211	root	1.49
212	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
213	root	1.46	- greatly improved small integer encoding and decoding speed.
214			- implement a number of µ-optimisations.
215	root	1.47	- updated benchmarks.
216	root	1.46
217	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
218	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
219			the required macros.
220	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
221	root	1.42
222	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
223	root	1.47	- character offset reported for trailing garbage was random.
224	root	1.41
225	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
226			- decode did not work with magical scalars (doh!).
227	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
228			of unicode.
229	root	1.39	- flag trailing garbage as error.
230			- new decode_prefix method that returns the number
231			of characters consumed by a decode.
232	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
233			as pointed out by Glenn Linderman.
234			- fixed typoe reported by YAMASHINA Hio.
235	root	1.34
236	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
237			- properly 0-terminate sv's returned by encode to help
238			C libraries that expect that 0 to be there.
239	root	1.31	- partially "port" JSON from C to microsofts fucking broken
240			pseudo-C. They should be burned to the ground for pissing
241			on standards. And I should be stoned for even trying to
242	root	1.32	support this filthy excuse for a c compiler.
243	root	1.6
244	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
245	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
246	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
247			leading to segfaults.
248	root	1.30	- further reduced default nesting depth to 512 due to the test
249			failure by that anonymous "chris" whose e-mail address seems
250			to be impossible to get. Tests on other freebsd systems indicate
251			that this is likely a problem in his/her configuration and not this
252			module.
253			- renamed json => JSON in error messages.
254			- corrected the character offset in some error messages.
255	root	1.28
256	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
257			- do not segfault when from_json/decode gets passed
258			a non-string object (reported by Florian Ragwitz).
259			This has no effect on normal operation.
260
261	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
262			- the long awaited (by me) 1.0 version.
263			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
264			true and false.
265	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
266	root	1.25	- improve testsuite.
267	root	1.26	- halve the default nesting depth limit, to hopefully make it
268	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
269			send me his report, so I cannot ask about the stack limit on fbsd).
270	root	1.24
271	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
272	root	1.21	- fix a memleak when decoding hashes.
273	root	1.20	- export jsonToBj and objToJson as aliases
274			to to_json and from_json, to reduce incompatibilities
275			between JSON/JSON::PC and JSON::XS. (experimental).
276	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
277			- added a security considerations sections.
278	root	1.20
279	root	1.19	0.7 Sun Mar 25 01:46:30 CET 2007
280	root	1.16	- code cleanup.
281			- fix a memory overflow bug when indenting.
282			- pretty-printing now up to 15% faster.
283			- improve decoding speed of strings by
284			up to 50% by specialcasing short strings.
285			- further decoding speedups for strings using
286			lots of \u escapes.
287	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
288	root	1.16
289	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
290	root	1.14	- added the UTF-16 encoding example hinted at in previous
291			versions.
292			- minor documentation fixes.
293	root	1.15	- fix a bug in and optimise canonicalising fastpath
294			(reported by Craig Manley).
295			- remove a subtest that breaks with bleadperl (reported
296			by Andreas König).
297	root	1.14
298	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
299	root	1.12	- documentation updates.
300	root	1.13	- do some casting to hopefully fix Andreas' problem.
301			- nuke bogus json rpc stuff.
302	root	1.12
303	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
304	root	1.5	- remove spurious PApp::Util reference (John McNamara).
305			- adapted lots of tests from other json modules
306			(idea by Chris Carline).
307	root	1.9	- documented mapping from json to perl and vice versa.
308	root	1.11	- improved the documentation by adding more examples.
309	root	1.5	- added short escaping forms, reducing the created
310			json texts a bit.
311			- added shrink flag.
312			- when flag methods are called without enable argument
313			they will by default enable their flag.
314			- considerably improved string encoding speed (at least
315			with gcc 4).
316	root	1.7	- added a test that covers lots of different characters.
317			- clarified some error messages.
318			- error messages now use correct character offset
319			with F_UTF8.
320	root	1.8	- improve the "no bytes" and "no warnings" hacks in
321			case the called functions do... stuff.
322	root	1.9	- croak when encoding to ascii and an out-of-range
323			(non-unicode) codepoint is encountered.
324	root	1.4
325	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
326	root	1.109	- the "could not sleep without debugging release".
327	root	1.3	it should basically work now, with many bugs as
328			no production tests have been run yet.
329			- added more testcases.
330			- the expected shitload of bugfixes.
331			- handle utf8 flag correctly in decode.
332			- fix segfault in decoder.
333			- utf8n_to_uvuni sets retlen to -1, but retlen is an
334			unsigned types (argh).
335			- fix decoding of utf-8 strings.
336			- improved error diagnostics.
337			- fix decoding of 'null'.
338			- fix parsing of empty array/hashes
339			- silence warnings when we prepare the croak message.
340
341	root	1.2	0.1 Thu Mar 22 22:13:43 CET 2007
342			- first release, very untested, basically just to claim
343			the namespace.
344	root	1.1
345			0.01 Thu Mar 22 06:08:12 CET 2007
346			- original version; cloned from Convert-Scalar
347
