94.02 Wed Mar 6 08:31:24 CET 2019
10 - undo the fix from 4.01, it breaks more things than it fixes
11 (another tetscase by Wesley Schwengle).
12 - try a proper fix this time.
13
144.01 Sun Feb 24 05:03:30 CET 2019
15 - fix some stack corruption caused mostly when calling methods
16 in list context (testcase by Wesley Schwengle).
17
184.0 Fri Nov 16 00:06:54 CET 2018
19 - SECURITY IMPLICATION: this release enables allow_nonref by default
20 for compatibnility with RFC 7159 and newer. See "old" vs. "new"
21 JSON under SECURITY CONSIDERATIONS.
22 - reworked the "old" vs. "new" JSON section.
23 - add ->boolean_values to provide the values to which booleans
24 decode (requested by Aristotle Pagaltzis).
25 - decode would wrongly accept ASCII NUL characters instead of
26 reporting them as trailing garbage.
27 - work around what smells like a perl bug w.r.t. exceptions
28 thrown in callbacks.
29 - incremental parser now more or less respects allow_nonref.
30 - json_xs json-pretty now enables canonical mode.
31 - add documentation section about I-JSON.
32 - minor documentation fixes/updates.
33
343.04 Thu Aug 17 04:30:47 CEST 2017
35 - change exponential realloc algorithm on encoding and string decoding to be
36 really exponential (this helps slow/debugging allocators such as libumem)
37 (reported by Matthew Horsfall).
38 - string encoding would needlessly overallocate output space
39 (testcase by Matthew Horsfall).
40 - be very paranoid about extending buffer lengths and croak if buffers get too large,
41 which might (or might not) improve security.
42 - add cbor-packed type to json_xs.
43 - switch from YAML to YAML::XS in json_xs, as YAML is way too buggy and outdated.
44
453.03 Wed Nov 16 20:20:59 CET 2016
46 - fix a bug introduced by a perl bug workaround that would cause
47 incremental parsing to fail with a sv_chop panic.
48 - json_xs: toformat failure error message fixed.
49 - json_xs: allow cyclic data structures in CBOR.
50
513.02 Fri Feb 26 22:45:20 CET 2016
52 - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean)
53 as well (reported by Alex Efros).
54 - allow literal tabs in strings in relaxed mode (patch by
55 lubo.rintel@gooddata.com).
56 - support "cbor" format in json_xs tool.
57 - support (and fix) calling encode and decode in list context
58 (reported by Вадим Власов).
59 - work around a bug in older perls crashing when presented
60 with shared hash keys (Reini Urban).
61 - use stability canary.
62
633.01 Tue Oct 29 16:55:15 CET 2013
64 - backport to perls < 5.18 (reported by Paul Howarth).
65
663.0 Tue Oct 29 01:35:37 CET 2013
67 - implemented an object tagging extension (using the
68 Types::Serialiser serialisation protocol).
69 - reworked the documentation regarding object serialisation,
70 add a new OBJECT SERIALISATION section that explains th
71 whole process.
72 - new setting: allow_tags.
73 - switch to Types::Serialiser booleans.
74 - remove to_json/from_json.
75 - other minor improvements to the documentation.
76
772.34 Thu May 23 11:30:34 CEST 2013
78 - work around bugs in perl 5.18 breaking more than 100
79 widely used modules, without a fix in sight because
80 p5pers don't care about CPAN anymore.
81 - when canonicalising, only allocate up to 64 hash key
82 pointers on the stack. for larger hashes, use the heap,
83 to avoid using too much stackspace.
84 - discuss the problem with setlocale (reported by a few victims).
85
862.33 Wed Aug 1 21:03:52 CEST 2012
87 - internal encode/decode XS wrappers did not expect stack
88 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
89 - add bencode as to/from option in bin/json_xs.
90 - add -e option to json_xs, and none and string in/out formats.
91
922.32 Thu Aug 11 19:06:38 CEST 2011
93 - fix a bug in the initial whitespace accumulation.
94
952.31 Wed Jul 27 17:53:05 CEST 2011
96 - don't accumulate initial whitespace in the incremental buffer
97 (this can be useful to allow whitespace-keepalive on a tcp
98 connection without triggering the max_size limit).
99 - properly croak on some invalid inputs that are not strings
100 (e.g. undef) when trying to decode a json text (reported
101 and analyzed by Goro Fuji).
102
1032.3 Wed Aug 18 01:26:47 CEST 2010
104 - make sure decoder doesn't change the decoding in the incremental
105 parser (testcase provided by Hendrik Schumacher).
106 - applied patch by DaTa for Data::Dumper support in json_xs.
107 - added -t dump support to json_xs, using Data::Dump.
108 - added -f eval support to json_xs.
109
1102.29 Wed Mar 17 02:39:12 CET 2010
111 - fix a memory leak when callbacks set using filter_json_object
112 or filter_json_single_key_object were called (great testcase
113 by Eric Wilhelm).
114
1152.28 Thu Mar 11 20:30:46 CET 2010
116 - implement our own atof function - perl's can be orders of
117 magnitudes slower than even the system one. on the positive
118 side, ours seems to be more exact in general than perl's.
119 (testcase provided by Tim Meadowcroft).
120 - clarify floating point conversion issues a bit.
121 - update jpsykes csrf article url.
122 - updated benchmark section - JSON::PP became much faster!
123
1242.27 Thu Jan 7 07:35:08 CET 2010
125 - support relaxed option inside the incremental parser
126 (testcase provided by IKEGAMI via Makamaka).
127
1282.26 Sat Oct 10 03:26:19 CEST 2009
129 - big integers could become truncated (based on patch
130 by Strobl Anton).
131 - output format change: indent now adds a final newline, which is
132 more expected and more true to the documentation.
133
1342.25 Sat Aug 8 12:04:41 CEST 2009
135 - the perl debugger completely breaks lvalue subs - try to work
136 around the issue.
137 - ignore RMAGICAL hashes w.r.t. CANONICAL.
138 - try to work around a possible char signedness issue on aix.
139 - require common sense.
140
1412.24 Sat May 30 08:25:45 CEST 2009
142 - the incremental parser did not update its parse offset
143 pointer correctly when parsing utf8-strings (nicely
144 debugged by Martin Evans).
145 - appending a non-utf8-string to the incremental parser
146 in utf8 mode failed to upgrade the string.
147 - wording of parse error messages has been improved.
148
1492.232 Sun Feb 22 11:12:25 CET 2009
150 - use an exponential algorithm to extend strings, to
151 help platforms with bad or abysmal==windows memory
152 allocater performance, at the expense of some memory
153 wastage (use shrink to recover this extra memory).
154 (nicely analysed by Dmitry Karasik).
155
1562.2311 Thu Feb 19 02:12:54 CET 2009
157 - add a section "JSON and ECMAscript" to explain some
158 incompatibilities between the two (problem was noted by
159 various people).
160 - add t/20_faihu.t.
161
1622.231 Thu Nov 20 04:59:08 CET 2008
163 - work around 5.10.0 magic bugs where manipulating magic values
164 (such as $1) would permanently damage them as perl would
165 ignore the magicalness, by making a full copy of the string,
166 reported by Dmitry Karasik.
167 - work around spurious warnings under older perl 5.8's.
168
1692.23 Mon Sep 29 05:08:29 CEST 2008
170 - fix a compilation problem when perl is not using char * as, well,
171 char *.
172 - use PL_hexdigit in favour of rolling our own.
173
1742.2222 Sun Jul 20 18:49:00 CEST 2008
175 - same game again, broken 5.10 finds yet another assertion
176 failure, and the workaround causes additional runtime warnings.
177 Work around the next assertion AND the warning. 5.10 seriously
178 needs to adjust it's attitude against working code.
179
1802.222 Sat Jul 19 06:15:34 CEST 2008
181 - you work around one -DDEBUGGING assertion bug in perl 5.10
182 just to hit the next one. work around this one, too.
183
1842.22 Tue Jul 15 13:26:51 CEST 2008
185 - allow higher nesting levels in incremental parser.
186 - error out earlier in some cases in the incremental parser
187 (as suggested by Yuval Kogman).
188 - improve incr-parser test (Yuval Kogman).
189
1902.21 Tue Jun 3 08:43:23 CEST 2008
191 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
192 - remove the experimental status of the incremental parser interface.
193 - move =encoding around again, to avoid bugs with search.cpan.org.
194 when can we finally have utf-8 in pod???
195 - add ->incr_reset method.
196
1972.2 Wed Apr 16 20:37:25 CEST 2008
198 - lifted the log2 rounding restriction of max_depth and max_size.
199 - make booleans mutable by creating a copy instead of handing out
200 the same scalar (reported by pasha sadri).
201 - added support for incremental json parsing (still EXPERIMENTAL).
202 - implemented and added a json_xs command line utility that can convert
203 from/to a number of serialisation formats - tell me if you need more.
204 - implement allow_unknown/get_allow_unknown methods.
205 - fixed documentation of max_depth w.r.t. higher and equal.
206 - moved down =encoding directive a bit, too much breaks if it's the first
207 pod directive :/.
208 - removed documentation section on other modules, it became somewhat
209 outdated and is nowadays mostly of historical interest.
210
2112.1 Wed Mar 19 23:23:18 CET 2008
3 - update documentation here and there, add a large section 212 - update documentation here and there: add a large section

221 - fix some issues with UV to JSON conversion of unknown impact.
10 - published the yahoo locals search result used in benchmarks as the 222 - published the yahoo locals search result used in benchmarks as the
