3TODO: object filtering (decode_filtered?) 3TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)
4TODO: make xs-level object bigger, longer 4TODO: maybe avoid the reblessing and better support readonly objects.

7TODO: how to cope with tagged values and standard json decoders
83.01 Tue Oct 29 16:55:15 CET 2013
9 - backport to perls < 5.18 (reported by Paul Howarth).
10
113.0 Tue Oct 29 01:35:37 CET 2013
12 - implemented an object tagging extension (using the
13 Types::Serialiser serialisation protocol).
14 - reworked the documentation regarding object serialisation,
15 add a new OBJECT SERIALISATION section that explains the
16 whole process.
17 - new setting: allow_tags.
18 - switch to Types::Serialiser booleans.
19 - remove to_json/from_json.
20 - other minor improvements to the documentation.
21
222.34 Thu May 23 11:30:34 CEST 2013
23 - work around bugs in perl 5.18 breaking more than 100
24 widely used modules, without a fix in sight because
25 p5pers don't care about CPAN anymore.
26 - when canonicalising, only allocate up to 64 hash key
27 pointers on the stack. for larger hashes, use the heap,
28 to avoid using too much stackspace.
29 - discuss the problem with setlocale (reported by a few victims).
30
312.33 Wed Aug 1 21:03:52 CEST 2012
32 - internal encode/decode XS wrappers did not expect stack
33 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
34 - add bencode as to/from option in bin/json_xs.
35 - add -e option to json_xs, and none and string in/out formats.
36
372.32 Thu Aug 11 19:06:38 CEST 2011
38 - fix a bug in the initial whitespace accumulation.
39
402.31 Wed Jul 27 17:53:05 CEST 2011
41 - don't accumulate initial whitespace in the incremental buffer
42 (this can be useful to allow whitespace-keepalive on a tcp
43 connection without triggering the max_size limit).
44 - properly croak on some invalid inputs that are not strings
45 (e.g. undef) when trying to decode a json text (reported
46 and analyzed by Goro Fuji).
47
482.3 Wed Aug 18 01:26:47 CEST 2010
49 - make sure decoder doesn't change the decoding in the incremental
50 parser (testcase provided by Hendrik Schumacher).
51 - applied patch by DaTa for Data::Dumper support in json_xs.
52 - added -t dump support to json_xs, using Data::Dump.
53 - added -f eval support to json_xs.
54
552.29 Wed Mar 17 02:39:12 CET 2010
56 - fix a memory leak when callbacks set using filter_json_object
57 or filter_json_single_key_object were called (great testcase
58 by Eric Wilhelm).
59
602.28 Thu Mar 11 20:30:46 CET 2010
61 - implement our own atof function - perl's can be orders of
62 magnitudes slower than even the system one. on the positive
63 side, ours seems to be more exact in general than perl's.
64 (testcase provided by Tim Meadowcroft).
65 - clarify floating point conversion issues a bit.
66 - update jpsykes csrf article url.
67 - updated benchmark section - JSON::PP became much faster!
68
692.27 Thu Jan 7 07:35:08 CET 2010
70 - support relaxed option inside the incremental parser
71 (testcase provided by IKEGAMI via Makamaka).
72
732.26 Sat Oct 10 03:26:19 CEST 2009
74 - big integers could become truncated (based on patch
75 by Strobl Anton).
76 - output format change: indent now adds a final newline, which is
77 more expected and more true to the documentation.
78
792.25 Sat Aug 8 12:04:41 CEST 2009
80 - the perl debugger completely breaks lvalue subs - try to work
81 around the issue.
82 - ignore RMAGICAL hashes w.r.t. CANONICAL.
83 - try to work around a possible char signedness issue on aix.
84 - require common sense.
85
862.24 Sat May 30 08:25:45 CEST 2009
87 - the incremental parser did not update its parse offset
88 pointer correctly when parsing utf8-strings (nicely
89 debugged by Martin Evans).
90 - appending a non-utf8-string to the incremental parser
91 in utf8 mode failed to upgrade the string.
92 - wording of parse error messages has been improved.
93
942.232 Sun Feb 22 11:12:25 CET 2009
95 - use an exponential algorithm to extend strings, to
96 help platforms with bad or abysmal==windows memory
97 allocater performance, at the expense of some memory
98 wastage (use shrink to recover this extra memory).
99 (nicely analysed by Dmitry Karasik).
100
1012.2311 Thu Feb 19 02:12:54 CET 2009
102 - add a section "JSON and ECMAscript" to explain some
103 incompatibilities between the two (problem was noted by
104 various people).
105 - add t/20_faihu.t.
106
1072.231 Thu Nov 20 04:59:08 CET 2008
108 - work around 5.10.0 magic bugs where manipulating magic values
109 (such as $1) would permanently damage them as perl would
110 ignore the magicalness, by making a full copy of the string,
111 reported by Dmitry Karasik.
112 - work around spurious warnings under older perl 5.8's.
113
1142.23 Mon Sep 29 05:08:29 CEST 2008
115 - fix a compilation problem when perl is not using char * as, well,
116 char *.
117 - use PL_hexdigit in favour of rolling our own.
118
1192.2222 Sun Jul 20 18:49:00 CEST 2008
120 - same game again, broken 5.10 finds yet another assertion
121 failure, and the workaround causes additional runtime warnings.
122 Work around the next assertion AND the warning. 5.10 seriously
123 needs to adjust it's attitude against working code.
124
1252.222 Sat Jul 19 06:15:34 CEST 2008
126 - you work around one -DDEBUGGING assertion bug in perl 5.10
127 just to hit the next one. work around this one, too.
128
1292.22 Tue Jul 15 13:26:51 CEST 2008
130 - allow higher nesting levels in incremental parser.
131 - error out earlier in some cases in the incremental parser
132 (as suggested by Yuval Kogman).
133 - improve incr-parser test (Yuval Kogman).
134
1352.21 Tue Jun 3 08:43:23 CEST 2008
136 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
137 - remove the experimental status of the incremental parser interface.
138 - move =encoding around again, to avoid bugs with search.cpan.org.
139 when can we finally have utf-8 in pod???
140 - add ->incr_reset method.
141
1422.2 Wed Apr 16 20:37:25 CEST 2008
143 - lifted the log2 rounding restriction of max_depth and max_size.
144 - make booleans mutable by creating a copy instead of handing out
145 the same scalar (reported by pasha sadri).
146 - added support for incremental json parsing (still EXPERIMENTAL).
147 - implemented and added a json_xs command line utility that can convert
148 from/to a number of serialisation formats - tell me if you need more.
149 - implement allow_unknown/get_allow_unknown methods.
150 - fixed documentation of max_depth w.r.t. higher and equal.
151 - moved down =encoding directive a bit, too much breaks if it's the first
152 pod directive :/.
153 - removed documentation section on other modules, it became somewhat
154 outdated and is nowadays mostly of historical interest.
155
1562.1 Wed Mar 19 23:23:18 CET 2008
157 - update documentation here and there: add a large section
158 about utf8/latin1/ascii flags, add a security consideration
159 and extend and clarify the JSON and YAML section.
160 - medium speed enhancements when encoding/decoding non-ascii chars.
161 - minor speedup in number encoding case.
162 - extend and clarify the section on incompatibilities
163 between YAML and JSON.
164 - switch to static inline from just inline when using gcc.
165 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
166 - fix some issues with UV to JSON conversion of unknown impact.
167 - published the yahoo locals search result used in benchmarks as the
168 original url changes so comparison is impossible.
169
1702.01 Wed Dec 5 11:40:28 CET 2007
171 - INCOMPATIBLE API CHANGE: to_json and from_json have been
172 renamed to encode_json/decode_json for JSON.pm compatibility.
173 The old functions croak and might be replaced by JSON.pm
174 comaptible versions in some later release.
175
1762.0 Tue Dec 4 11:30:46 CET 2007
177 - this is supposed to be the first version of JSON::XS
178 compatible with version 2.0+ of the JSON module.
179 Using the JSON module as frontend to JSON::XS should be
180 as fast as using JSON::XS directly, so consider using it
181 instead.
182 - added get_* methods for all "simple" options.
183 - make JSON::XS subclassable.
184
1851.53 Tue Nov 13 23:58:33 CET 2007
186 - minor doc clarifications.
187 - fixed many doc typos (patch by Thomas L. Shinnick).
188
1891.52 Mon Oct 15 03:22:06 CEST 2007
190 - remove =encoding pod directive again, it confuses too many pod
191 parsers :/.
192
1931.51 Sat Oct 13 03:55:56 CEST 2007
194 - encode empty arrays/hashes in a compact way when pretty is enabled.
195 - apparently JSON::XS was used to find some bugs in the
196 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
197 the testsuite.
198 - quite a bit of doc updates/extension.
199 - require 5.8.2, as this seems to be the first unicode-stable version.
200
2011.5 Tue Aug 28 04:05:38 CEST 2007
202 - add support for tied hashes, based on ideas and testcase by
203 Marcus Holland-Moritz.
204 - implemented relaxed parsing mode where some extensions are being
205 accepted. generation is still JSON-only.
206
2071.44 Wed Aug 22 01:02:44 CEST 2007
208 - very experimental process-emulation support, slowing everything down.
209 the horribly broken perl threads are still not supported - YMMV.
210
2111.43 Thu Jul 26 13:26:37 CEST 2007
212 - convert big json numbers exclusively consisting of digits to NV
213 only when there is no loss of precision, otherwise to string.
214
2151.42 Tue Jul 24 00:51:18 CEST 2007
216 - fix a crash caused by not handling missing array elements
217 (report and testcase by Jay Kuri).
218
2191.41 Tue Jul 10 18:21:44 CEST 2007
220 - fix compilation with NDEBUG (assert side-effect),
221 affects convert_blessed only.
222 - fix a bug in decode filters calling ENTER; SAVETMPS;
223 one time too often.
224 - catch a typical error in TO_JSON methods.
225 - antique-ised XS.xs again to work with outdated
226 C compilers (windows...).
227
2281.4 Mon Jul 2 10:06:30 CEST 2007
6 - add convert_blessed option. 229 - add convert_blessed setting.
7 - encode did not catch all blessed objects, encoding their 230 - encode did not catch all blessed objects, encoding their
8 contents in most cases. This has been fixed by introducing 231 contents in most cases. This has been fixed by introducing
9 the allow_blessed setting. 232 the allow_blessed setting.
233 - added filter_json_object and filter_json_single_key_object
234 settings that specify a callback to be called when
235 all/specific json objects are encountered.
10 - assume that most object keys are simple ascii words and 236 - assume that most object keys are simple ascii words and
11 optimise this case, penalising the general case. This can 237 optimise this case, penalising the general case. This can
12 speed up decoding by 30% in typical cases and gives 238 speed up decoding by 30% in typical cases and gives
13 a smaller and faster perl hash. 239 a smaller and faster perl hash.
14 - implemented simpleminded, optional resource size checking 240 - implemented simpleminded, optional resource size checking
15 in decode_json. 241 in decode_json.
16 - remove objToJson/jsonToObj aliases, as the next version 242 - remove objToJson/jsonToObj aliases, as the next version
17 of JSON will not have them either. 243 of JSON will not have them either.
18 - bit the bullet and converted the very simple json object 244 - bit the bullet and converted the very simple json object
19 into a more complex one. 245 into a more complex one.
246 - work around a bug where perl wrongly claims an integer
247 is not an integer.
248 - unbundle JSON::XS::Boolean into own pm file so Storable
249 and similar modules can resolve the overloading when thawing.
20 250
211.3 Sun Jun 24 01:55:02 CEST 2007 2511.3 Sun Jun 24 01:55:02 CEST 2007
22 - make JSON::XS::true and false special overloaded objects 252 - make JSON::XS::true and false special overloaded objects
23 and return those instead of 1 and 0 for those json atoms 253 and return those instead of 1 and 0 for those json atoms
24 (JSON::PP compatibility is NOT achieved yet). 254 (JSON::PP compatibility is NOT achieved yet).
