3TODO: maybe use some overload magic to decode true and false into something 32.25 Sat Aug 8 12:04:41 CEST 2009
4 not 0 or 1 in perl. or use attached magic? 4 - the perl debugger completely breaks lvalue subs - try to work
5TODO: get rid of dynamic arrays to support so-called C compilers 5 around the issue.
6 by fucking microsoft that do not do C. argl, snprintf is also 6 - ignore RMAGICAL hashes w.r.t. CANONICAL.
7 missing. 7 - try to work around a possible char signedness issue on aix.
8 - require common sense.

102.24 Sat May 30 08:25:45 CEST 2009
11 - the incremental parser did not update its parse offset
12 pointer correctly when parsing utf8-strings (nicely
13 debugged by Martin Evans).
14 - appending a non-utf8-string to the incremental parser
15 in utf8 mode failed to upgrade the string.
16 - wording of parse error messages has been improved.
17
182.232 Sun Feb 22 11:12:25 CET 2009
19 - use an exponential algorithm to extend strings, to
20 help platforms with bad or abysmal==windows memory
21 allocater performance, at the expense of some memory
22 wastage (use shrink to recover this extra memory).
23 (nicely analysed by Dmitry Karasik).
24
252.2311 Thu Feb 19 02:12:54 CET 2009
26 - add a section "JSON and ECMAscript" to explain some
27 incompatibilities between the two (problem was noted by
28 various people).
29 - add t/20_faihu.t.
30
312.231 Thu Nov 20 04:59:08 CET 2008
32 - work around 5.10.0 magic bugs where manipulating magic values
33 (such as $1) would permanently damage them as perl would
34 ignore the magicalness, by making a full copy of the string,
35 reported by Dmitry Karasik.
36 - work around spurious warnings under older perl 5.8's.
37
382.23 Mon Sep 29 05:08:29 CEST 2008
39 - fix a compilation problem when perl is not using char * as, well,
40 char *.
41 - use PL_hexdigit in favour of rolling our own.
42
432.2222 Sun Jul 20 18:49:00 CEST 2008
44 - same game again, broken 5.10 finds yet another assertion
45 failure, and the workaround causes additional runtime warnings.
46 Work around the next assertion AND the warning. 5.10 seriously
47 needs to adjust it's attitude against working code.
48
492.222 Sat Jul 19 06:15:34 CEST 2008
50 - you work around one -DDEBUGGING assertion bug in perl 5.10
51 just to hit the next one. work around this one, too.
52
532.22 Tue Jul 15 13:26:51 CEST 2008
54 - allow higher nesting levels in incremental parser.
55 - error out earlier in some cases in the incremental parser
56 (as suggested by Yuval Kogman).
57 - improve incr-parser test (Yuval Kogman).
58
592.21 Tue Jun 3 08:43:23 CEST 2008
60 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
61 - remove the experimental status of the incremental parser interface.
62 - move =encoding around again, to avoid bugs with search.cpan.org.
63 when can we finally have utf-8 in pod???
64 - add ->incr_reset method.
65
662.2 Wed Apr 16 20:37:25 CEST 2008
67 - lifted the log2 rounding restriction of max_depth and max_size.
68 - make booleans mutable by creating a copy instead of handing out
69 the same scalar (reported by pasha sadri).
70 - added support for incremental json parsing (still EXPERIMENTAL).
71 - implemented and added a json_xs command line utility that can convert
72 from/to a number of serialisation formats - tell me if you need more.
73 - implement allow_unknown/get_allow_unknown methods.
74 - fixed documentation of max_depth w.r.t. higher and equal.
75 - moved down =encoding directive a bit, too much breaks if it's the first
76 pod directive :/.
77 - removed documentation section on other modules, it became somewhat
78 outdated and is nowadays mostly of historical interest.
79
802.1 Wed Mar 19 23:23:18 CET 2008
81 - update documentation here and there: add a large section
82 about utf8/latin1/ascii flags, add a security consideration
83 and extend and clarify the JSON and YAML section.
84 - medium speed enhancements when encoding/decoding non-ascii chars.
85 - minor speedup in number encoding case.
86 - extend and clarify the section on incompatibilities
87 between YAML and JSON.
88 - switch to static inline from just inline when using gcc.
89 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
90 - fix some issues with UV to JSON conversion of unknown impact.
91 - published the yahoo locals search result used in benchmarks as the
92 original url changes so comparison is impossible.
93
942.01 Wed Dec 5 11:40:28 CET 2007
95 - INCOMPATIBLE API CHANGE: to_json and from_json have been
96 renamed to encode_json/decode_json for JSON.pm compatibility.
97 The old functions croak and might be replaced by JSON.pm
98 comaptible versions in some later release.
99
1002.0 Tue Dec 4 11:30:46 CET 2007
101 - this is supposed to be the first version of JSON::XS
102 compatible with version 2.0+ of the JSON module.
103 Using the JSON module as frontend to JSON::XS should be
104 as fast as using JSON::XS directly, so consider using it
105 instead.
106 - added get_* methods for all "simple" options.
107 - make JSON::XS subclassable.
108
1091.53 Tue Nov 13 23:58:33 CET 2007
110 - minor doc clarifications.
111 - fixed many doc typos (patch by Thomas L. Shinnick).
112
1131.52 Mon Oct 15 03:22:06 CEST 2007
114 - remove =encoding pod directive again, it confuses too many pod
115 parsers :/.
116
1171.51 Sat Oct 13 03:55:56 CEST 2007
118 - encode empty arrays/hashes in a compact way when pretty is enabled.
119 - apparently JSON::XS was used to find some bugs in the
120 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
121 the testsuite.
122 - quite a bit of doc updates/extension.
123 - require 5.8.2, as this seems to be the first unicode-stable version.
124
1251.5 Tue Aug 28 04:05:38 CEST 2007
126 - add support for tied hashes, based on ideas and testcase by
127 Marcus Holland-Moritz.
128 - implemented relaxed parsing mode where some extensions are being
129 accepted. generation is still JSON-only.
130
1311.44 Wed Aug 22 01:02:44 CEST 2007
132 - very experimental process-emulation support, slowing everything down.
133 the horribly broken perl threads are still not supported - YMMV.
134
1351.43 Thu Jul 26 13:26:37 CEST 2007
136 - convert big json numbers exclusively consisting of digits to NV
137 only when there is no loss of precision, otherwise to string.
138
1391.42 Tue Jul 24 00:51:18 CEST 2007
140 - fix a crash caused by not handling missing array elements
141 (report and testcase by Jay Kuri).
142
1431.41 Tue Jul 10 18:21:44 CEST 2007
144 - fix compilation with NDEBUG (assert side-effect),
145 affects convert_blessed only.
146 - fix a bug in decode filters calling ENTER; SAVETMPS;
147 one time too often.
148 - catch a typical error in TO_JSON methods.
149 - antique-ised XS.xs again to work with outdated
150 C compilers (windows...).
151
1521.4 Mon Jul 2 10:06:30 CEST 2007
153 - add convert_blessed setting.
154 - encode did not catch all blessed objects, encoding their
155 contents in most cases. This has been fixed by introducing
156 the allow_blessed setting.
157 - added filter_json_object and filter_json_single_key_object
158 settings that specify a callback to be called when
159 all/specific json objects are encountered.
160 - assume that most object keys are simple ascii words and
161 optimise this case, penalising the general case. This can
162 speed up decoding by 30% in typical cases and gives
163 a smaller and faster perl hash.
164 - implemented simpleminded, optional resource size checking
165 in decode_json.
166 - remove objToJson/jsonToObj aliases, as the next version
167 of JSON will not have them either.
168 - bit the bullet and converted the very simple json object
169 into a more complex one.
170 - work around a bug where perl wrongly claims an integer
171 is not an integer.
172 - unbundle JSON::XS::Boolean into own pm file so Storable
173 and similar modules can resolve the overloading when thawing.
174
1751.3 Sun Jun 24 01:55:02 CEST 2007
176 - make JSON::XS::true and false special overloaded objects
177 and return those instead of 1 and 0 for those json atoms
178 (JSON::PP compatibility is NOT achieved yet).
179 - add JSON::XS::is_bool predicate to test for those special
180 values.
181 - add a reference to
182 http://jpsykes.com/47/practical-csrf-and-json-security.
183 - removed require 5.8.8 again, it is just not very expert-friendly.
184 Also try to be more compatible with slightly older versions,
185 which are not recommended (because they are buggy).
186
1871.24 Mon Jun 11 05:40:49 CEST 2007
188 - added informative section on JSON-as-YAML.
189 - get rid of some c99-isms again.
190 - localise dec->cur in decode_str, speeding up
191 string decoding considerably (>15% on my amd64 + gcc).
192 - increased SHORT_STRING_LEN to 16kb: stack space is
193 usually plenty, and this actually saves memory
194 when !shrinking as short strings will fit perfectly.
195
1961.23 Wed Jun 6 20:13:06 CEST 2007
197 - greatly improved small integer encoding and decoding speed.
198 - implement a number of ยต-optimisations.
199 - updated benchmarks.
200
2011.22 Thu May 24 00:07:25 CEST 2007
202 - require 5.8.8 explicitly as older perls do not seem to offer
203 the required macros.
204 - possibly made it compile on so-called C compilers by microsoft.

91.21 Wed May 9 18:40:32 CEST 2007 2061.21 Wed May 9 18:40:32 CEST 2007
