3TODO: document conversion algorithm 32.1 Wed Mar 19 23:23:18 CET 2008
4 - update documentation here and there: add a large section
5 about utf8/latin1/ascii flags, add a security consideration
6 and extend and clarify the JSON and YAML section.
7 - medium speed enhancements when encoding/decoding non-ascii chars.
8 - minor speedup in number encoding case.
9 - extend and clarify the section on incompatibilities
10 between YAML and JSON.
11 - switch to static inline from just inline when using gcc.
12 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
13 - fix some issues with UV to JSON conversion of unknown impact.
14 - published the yahoo locals search result used in benchmarks as the
15 original url changes so comparison is impossible.

50.3 172.01 Wed Dec 5 11:40:28 CET 2007
18 - INCOMPATIBLE API CHANGE: to_json and from_json have been
19 renamed to encode_json/decode_json for JSON.pm compatibility.
20 The old functions croak and might be replaced by JSON.pm
21 comaptible versions in some later release.
22
232.0 Tue Dec 4 11:30:46 CET 2007
24 - this is supposed to be the first version of JSON::XS
25 compatible with version 2.0+ of the JSON module.
26 Using the JSON module as frontend to JSON::XS should be
27 as fast as using JSON::XS directly, so consider using it
28 instead.
29 - added get_* methods for all "simple" options.
30 - make JSON::XS subclassable.
31
321.53 Tue Nov 13 23:58:33 CET 2007
33 - minor doc clarifications.
34 - fixed many doc typos (patch by Thomas L. Shinnick).
35
361.52 Mon Oct 15 03:22:06 CEST 2007
37 - remove =encoding pod directive again, it confuses too many pod
38 parsers :/.
39
401.51 Sat Oct 13 03:55:56 CEST 2007
41 - encode empty arrays/hashes in a compact way when pretty is enabled.
42 - apparently JSON::XS was used to find some bugs in the
43 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
44 the testsuite.
45 - quite a bit of doc updates/extension.
46 - require 5.8.2, as this seems to be the first unicode-stable version.
47
481.5 Tue Aug 28 04:05:38 CEST 2007
49 - add support for tied hashes, based on ideas and testcase by
50 Marcus Holland-Moritz.
51 - implemented relaxed parsing mode where some extensions are being
52 accepted. generation is still JSON-only.
53
541.44 Wed Aug 22 01:02:44 CEST 2007
55 - very experimental process-emulation support, slowing everything down.
56 the horribly broken perl threads are still not supported - YMMV.
57
581.43 Thu Jul 26 13:26:37 CEST 2007
59 - convert big json numbers exclusively consisting of digits to NV
60 only when there is no loss of precision, otherwise to string.
61
621.42 Tue Jul 24 00:51:18 CEST 2007
63 - fix a crash caused by not handling missing array elements
64 (report and testcase by Jay Kuri).
65
661.41 Tue Jul 10 18:21:44 CEST 2007
67 - fix compilation with NDEBUG (assert side-effect),
68 affects convert_blessed only.
69 - fix a bug in decode filters calling ENTER; SAVETMPS;
70 one time too often.
71 - catch a typical error in TO_JSON methods.
72 - antique-ised XS.xs again to work with outdated
73 C compilers (windows...).
74
751.4 Mon Jul 2 10:06:30 CEST 2007
76 - add convert_blessed setting.
77 - encode did not catch all blessed objects, encoding their
78 contents in most cases. This has been fixed by introducing
79 the allow_blessed setting.
80 - added filter_json_object and filter_json_single_key_object
81 settings that specify a callback to be called when
82 all/specific json objects are encountered.
83 - assume that most object keys are simple ascii words and
84 optimise this case, penalising the general case. This can
85 speed up decoding by 30% in typical cases and gives
86 a smaller and faster perl hash.
87 - implemented simpleminded, optional resource size checking
88 in decode_json.
89 - remove objToJson/jsonToObj aliases, as the next version
90 of JSON will not have them either.
91 - bit the bullet and converted the very simple json object
92 into a more complex one.
93 - work around a bug where perl wrongly claims an integer
94 is not an integer.
95 - unbundle JSON::XS::Boolean into own pm file so Storable
96 and similar modules can resolve the overloading when thawing.
97
981.3 Sun Jun 24 01:55:02 CEST 2007
99 - make JSON::XS::true and false special overloaded objects
100 and return those instead of 1 and 0 for those json atoms
101 (JSON::PP compatibility is NOT achieved yet).
102 - add JSON::XS::is_bool predicate to test for those special
103 values.
104 - add a reference to
105 http://jpsykes.com/47/practical-csrf-and-json-security.
106 - removed require 5.8.8 again, it is just not very expert-friendly.
107 Also try to be more compatible with slightly older versions,
108 which are not recommended (because they are buggy).
109
1101.24 Mon Jun 11 05:40:49 CEST 2007
111 - added informative section on JSON-as-YAML.
112 - get rid of some c99-isms again.
113 - localise dec->cur in decode_str, speeding up
114 string decoding considerably (>15% on my amd64 + gcc).
115 - increased SHORT_STRING_LEN to 16kb: stack space is
116 usually plenty, and this actually saves memory
117 when !shrinking as short strings will fit perfectly.
118
1191.23 Wed Jun 6 20:13:06 CEST 2007
120 - greatly improved small integer encoding and decoding speed.
121 - implement a number of µ-optimisations.
122 - updated benchmarks.
123
1241.22 Thu May 24 00:07:25 CEST 2007
125 - require 5.8.8 explicitly as older perls do not seem to offer
126 the required macros.
127 - possibly made it compile on so-called C compilers by microsoft.
128
1291.21 Wed May 9 18:40:32 CEST 2007
130 - character offset reported for trailing garbage was random.
131
1321.2 Wed May 9 18:35:01 CEST 2007
133 - decode did not work with magical scalars (doh!).
134 - added latin1 flag to produce JSON texts in the latin1 subset
135 of unicode.
136 - flag trailing garbage as error.
137 - new decode_prefix method that returns the number
138 of characters consumed by a decode.
139 - max octets/char in perls UTF-X is actually 13, not 11,
140 as pointed out by Glenn Linderman.
141 - fixed typoe reported by YAMASHINA Hio.
142
1431.11 Mon Apr 9 07:05:49 CEST 2007
144 - properly 0-terminate sv's returned by encode to help
145 C libraries that expect that 0 to be there.
146 - partially "port" JSON from C to microsofts fucking broken
147 pseudo-C. They should be burned to the ground for pissing
148 on standards. And I should be stoned for even trying to
149 support this filthy excuse for a c compiler.
150
1511.1 Wed Apr 4 01:45:00 CEST 2007
152 - clarify documentation (pointed out by Quinn Weaver).
153 - decode_utf8 sometimes did not correctly flag errors,
154 leading to segfaults.
155 - further reduced default nesting depth to 512 due to the test
156 failure by that anonymous "chris" whose e-mail address seems
157 to be impossible to get. Tests on other freebsd systems indicate
158 that this is likely a problem in his/her configuration and not this
159 module.
160 - renamed json => JSON in error messages.
161 - corrected the character offset in some error messages.
162
1631.01 Sat Mar 31 16:15:40 CEST 2007
164 - do not segfault when from_json/decode gets passed
165 a non-string object (reported by Florian Ragwitz).
166 This has no effect on normal operation.
167
1681.0 Thu Mar 29 04:43:34 CEST 2007
169 - the long awaited (by me) 1.0 version.
170 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
171 true and false.
172 - add some more notes to shrink, as suggested by Alex Efros.
173 - improve testsuite.
174 - halve the default nesting depth limit, to hopefully make it
175 work on Freebsd (unfortunately, the cpan tester did not
176 send me his report, so I cannot ask about the stack limit on fbsd).
177
1780.8 Mon Mar 26 00:10:48 CEST 2007
179 - fix a memleak when decoding hashes.
180 - export jsonToBj and objToJson as aliases
181 to to_json and from_json, to reduce incompatibilities
182 between JSON/JSON::PC and JSON::XS. (experimental).
183 - implement a maximum nesting depth for both en- and de-coding.
184 - added a security considerations sections.
185
1860.7 Sun Mar 25 01:46:30 CET 2007
187 - code cleanup.
188 - fix a memory overflow bug when indenting.
189 - pretty-printing now up to 15% faster.
190 - improve decoding speed of strings by
191 up to 50% by specialcasing short strings.
192 - further decoding speedups for strings using
193 lots of \u escapes.
194 - improve utf8 decoding speed for U+80 .. U+7FF.
195
1960.5 Sat Mar 24 20:41:51 CET 2007
197 - added the UTF-16 encoding example hinted at in previous
198 versions.
199 - minor documentation fixes.
200 - fix a bug in and optimise canonicalising fastpath
201 (reported by Craig Manley).
202 - remove a subtest that breaks with bleadperl (reported
203 by Andreas König).
204
2050.31 Sat Mar 24 02:14:34 CET 2007
206 - documentation updates.
207 - do some casting to hopefully fix Andreas' problem.
208 - nuke bogus json rpc stuff.
209

214 - documented mapping from json to perl and vice versa.
215 - improved the documentation by adding more examples.
9 - added short escaping forms, reducing the created 216 - added short escaping forms, reducing the created
10 json texts a bit. 217 json texts a bit.
11 - added shrink flag. 218 - added shrink flag.
12 - when flag methods are called without enable argument 219 - when flag methods are called without enable argument
13 they will by default enable their flag. 220 they will by default enable their flag.

17 - clarified some error messages. 224 - clarified some error messages.
18 - error messages now use correct character offset 225 - error messages now use correct character offset
19 with F_UTF8. 226 with F_UTF8.

21 case the called functions do... stuff. 228 case the called functions do... stuff.
229 - croak when encoding to ascii and an out-of-range
230 (non-unicode) codepoint is encountered.
