3TODO: allow a configurable recursion limit and/or or other forms of resource limiting (string size, memory usage...) 3 - remove the experimental status of the incremental parser interface.
4TODO: maybe simply use \0 and \1 as true/false when encoding (and overloaded/blessed versions thereof on 4 - move =encoding around again, to avoid bugs with search.cpan.org.
5 decoding?) 5 when can we finally have utf-8 in pod???

72.2 Wed Apr 16 20:37:25 CEST 2008
8 - lifted the log2 rounding restriction of max_depth and max_size.
9 - make booleans mutable by creating a copy instead of handing out
10 the same scalar (reported by pasha sadri).
11 - added support for incremental json parsing (still EXPERIMENTAL).
12 - implemented and added a json_xs command line utility that can convert
13 from/to a number of serialisation formats - tell me if you need more.
14 - implement allow_unknown/get_allow_unknown methods.
15 - fixed documentation of max_depth w.r.t. higher and equal.
16 - moved down =encoding directive a bit, too much breaks if it's the first
17 pod directive :/.
18 - removed documentation section on other modules, it became somewhat
19 outdated and is nowadays mostly of historical interest.
20
212.1 Wed Mar 19 23:23:18 CET 2008
22 - update documentation here and there: add a large section
23 about utf8/latin1/ascii flags, add a security consideration
24 and extend and clarify the JSON and YAML section.
25 - medium speed enhancements when encoding/decoding non-ascii chars.
26 - minor speedup in number encoding case.
27 - extend and clarify the section on incompatibilities
28 between YAML and JSON.
29 - switch to static inline from just inline when using gcc.
30 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
31 - fix some issues with UV to JSON conversion of unknown impact.
32 - published the yahoo locals search result used in benchmarks as the
33 original url changes so comparison is impossible.
34
352.01 Wed Dec 5 11:40:28 CET 2007
36 - INCOMPATIBLE API CHANGE: to_json and from_json have been
37 renamed to encode_json/decode_json for JSON.pm compatibility.
38 The old functions croak and might be replaced by JSON.pm
39 comaptible versions in some later release.
40
412.0 Tue Dec 4 11:30:46 CET 2007
42 - this is supposed to be the first version of JSON::XS
43 compatible with version 2.0+ of the JSON module.
44 Using the JSON module as frontend to JSON::XS should be
45 as fast as using JSON::XS directly, so consider using it
46 instead.
47 - added get_* methods for all "simple" options.
48 - make JSON::XS subclassable.
49
501.53 Tue Nov 13 23:58:33 CET 2007
51 - minor doc clarifications.
52 - fixed many doc typos (patch by Thomas L. Shinnick).
53
541.52 Mon Oct 15 03:22:06 CEST 2007
55 - remove =encoding pod directive again, it confuses too many pod
56 parsers :/.
57
581.51 Sat Oct 13 03:55:56 CEST 2007
59 - encode empty arrays/hashes in a compact way when pretty is enabled.
60 - apparently JSON::XS was used to find some bugs in the
61 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
62 the testsuite.
63 - quite a bit of doc updates/extension.
64 - require 5.8.2, as this seems to be the first unicode-stable version.
65
661.5 Tue Aug 28 04:05:38 CEST 2007
67 - add support for tied hashes, based on ideas and testcase by
68 Marcus Holland-Moritz.
69 - implemented relaxed parsing mode where some extensions are being
70 accepted. generation is still JSON-only.
71
721.44 Wed Aug 22 01:02:44 CEST 2007
73 - very experimental process-emulation support, slowing everything down.
74 the horribly broken perl threads are still not supported - YMMV.
75
761.43 Thu Jul 26 13:26:37 CEST 2007
77 - convert big json numbers exclusively consisting of digits to NV
78 only when there is no loss of precision, otherwise to string.
79
801.42 Tue Jul 24 00:51:18 CEST 2007
81 - fix a crash caused by not handling missing array elements
82 (report and testcase by Jay Kuri).
83
841.41 Tue Jul 10 18:21:44 CEST 2007
85 - fix compilation with NDEBUG (assert side-effect),
86 affects convert_blessed only.
87 - fix a bug in decode filters calling ENTER; SAVETMPS;
88 one time too often.
89 - catch a typical error in TO_JSON methods.
90 - antique-ised XS.xs again to work with outdated
91 C compilers (windows...).
92
931.4 Mon Jul 2 10:06:30 CEST 2007
94 - add convert_blessed setting.
95 - encode did not catch all blessed objects, encoding their
96 contents in most cases. This has been fixed by introducing
97 the allow_blessed setting.
98 - added filter_json_object and filter_json_single_key_object
99 settings that specify a callback to be called when
100 all/specific json objects are encountered.
101 - assume that most object keys are simple ascii words and
102 optimise this case, penalising the general case. This can
103 speed up decoding by 30% in typical cases and gives
104 a smaller and faster perl hash.
105 - implemented simpleminded, optional resource size checking
106 in decode_json.
107 - remove objToJson/jsonToObj aliases, as the next version
108 of JSON will not have them either.
109 - bit the bullet and converted the very simple json object
110 into a more complex one.
111 - work around a bug where perl wrongly claims an integer
112 is not an integer.
113 - unbundle JSON::XS::Boolean into own pm file so Storable
114 and similar modules can resolve the overloading when thawing.
115
1161.3 Sun Jun 24 01:55:02 CEST 2007
117 - make JSON::XS::true and false special overloaded objects
118 and return those instead of 1 and 0 for those json atoms
119 (JSON::PP compatibility is NOT achieved yet).
120 - add JSON::XS::is_bool predicate to test for those special
121 values.
122 - add a reference to
123 http://jpsykes.com/47/practical-csrf-and-json-security.
124 - removed require 5.8.8 again, it is just not very expert-friendly.
125 Also try to be more compatible with slightly older versions,
126 which are not recommended (because they are buggy).
127
1281.24 Mon Jun 11 05:40:49 CEST 2007
129 - added informative section on JSON-as-YAML.
130 - get rid of some c99-isms again.
131 - localise dec->cur in decode_str, speeding up
132 string decoding considerably (>15% on my amd64 + gcc).
133 - increased SHORT_STRING_LEN to 16kb: stack space is
134 usually plenty, and this actually saves memory
135 when !shrinking as short strings will fit perfectly.
136
1371.23 Wed Jun 6 20:13:06 CEST 2007
138 - greatly improved small integer encoding and decoding speed.
139 - implement a number of µ-optimisations.
140 - updated benchmarks.
141
1421.22 Thu May 24 00:07:25 CEST 2007
143 - require 5.8.8 explicitly as older perls do not seem to offer
144 the required macros.
145 - possibly made it compile on so-called C compilers by microsoft.
146
1471.21 Wed May 9 18:40:32 CEST 2007
148 - character offset reported for trailing garbage was random.
149
1501.2 Wed May 9 18:35:01 CEST 2007
151 - decode did not work with magical scalars (doh!).
152 - added latin1 flag to produce JSON texts in the latin1 subset
153 of unicode.
154 - flag trailing garbage as error.
155 - new decode_prefix method that returns the number
156 of characters consumed by a decode.
157 - max octets/char in perls UTF-X is actually 13, not 11,
158 as pointed out by Glenn Linderman.
159 - fixed typoe reported by YAMASHINA Hio.
160
1611.11 Mon Apr 9 07:05:49 CEST 2007
162 - properly 0-terminate sv's returned by encode to help
163 C libraries that expect that 0 to be there.
164 - partially "port" JSON from C to microsofts fucking broken
165 pseudo-C. They should be burned to the ground for pissing
166 on standards. And I should be stoned for even trying to
167 support this filthy excuse for a c compiler.
168
1691.1 Wed Apr 4 01:45:00 CEST 2007
170 - clarify documentation (pointed out by Quinn Weaver).
171 - decode_utf8 sometimes did not correctly flag errors,
172 leading to segfaults.
173 - further reduced default nesting depth to 512 due to the test
174 failure by that anonymous "chris" whose e-mail address seems
175 to be impossible to get. Tests on other freebsd systems indicate
176 that this is likely a problem in his/her configuration and not this
177 module.
178 - renamed json => JSON in error messages.
179 - corrected the character offset in some error messages.
180
1811.01 Sat Mar 31 16:15:40 CEST 2007
182 - do not segfault when from_json/decode gets passed
183 a non-string object (reported by Florian Ragwitz).
184 This has no effect on normal operation.
185
1861.0 Thu Mar 29 04:43:34 CEST 2007
187 - the long awaited (by me) 1.0 version.
188 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
189 true and false.
190 - add some more notes to shrink, as suggested by Alex Efros.
191 - improve testsuite.
192 - halve the default nesting depth limit, to hopefully make it
193 work on Freebsd (unfortunately, the cpan tester did not
194 send me his report, so I cannot ask about the stack limit on fbsd).
195
1960.8 Mon Mar 26 00:10:48 CEST 2007
197 - fix a memleak when decoding hashes.
198 - export jsonToBj and objToJson as aliases
199 to to_json and from_json, to reduce incompatibilities
200 between JSON/JSON::PC and JSON::XS. (experimental).
201 - implement a maximum nesting depth for both en- and de-coding.
202 - added a security considerations sections.
203
2040.7 Sun Mar 25 01:46:30 CET 2007
205 - code cleanup.
206 - fix a memory overflow bug when indenting.
207 - pretty-printing now up to 15% faster.
208 - improve decoding speed of strings by
209 up to 50% by specialcasing short strings.
210 - further decoding speedups for strings using
211 lots of \u escapes.
212 - improve utf8 decoding speed for U+80 .. U+7FF.
213
2140.5 Sat Mar 24 20:41:51 CET 2007
215 - added the UTF-16 encoding example hinted at in previous
216 versions.
217 - minor documentation fixes.
218 - fix a bug in and optimise canonicalising fastpath
219 (reported by Craig Manley).
220 - remove a subtest that breaks with bleadperl (reported
221 by Andreas König).
222
2230.31 Sat Mar 24 02:14:34 CET 2007
7 - documentation updates. 224 - documentation updates.
225 - do some casting to hopefully fix Andreas' problem.
226 - nuke bogus json rpc stuff.
