133.04 Thu Aug 17 04:30:47 CEST 2017
14 - change exponential realloc algorithm on encoding and string decoding to be
15 really exponential (this helps slow/debugging allocators such as libumem)
16 (reported by Matthew Horsfall).
17 - string encoding would needlessly overallocate output space
18 (testcase by Matthew Horsfall).
19 - be very paranoid about extending buffer lengths and croak if buffers get too large,
20 which might (or might not) improve security.
21 - add cbor-packed type to json_xs.
22 - switch from YAML to YAML::XS in json_xs, as YAML is way too buggy and outdated.
23
243.03 Wed Nov 16 20:20:59 CET 2016
25 - fix a bug introduced by a perl bug workaround that would cause
26 incremental parsing to fail with a sv_chop panic.
27 - json_xs: toformat failure error message fixed.
28 - json_xs: allow cyclic data structures in CBOR.
29
303.02 Fri Feb 26 22:45:20 CET 2016
31 - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean)
32 as well (reported by Alex Efros).
33 - allow literal tabs in strings in relaxed mode (patch by
34 lubo.rintel@gooddata.com).
35 - support "cbor" format in json_xs tool.
36 - support (and fix) calling encode and decode in list context
37 (reported by Вадим Власов).
38 - work around a bug in older perls crashing when presented
39 with shared hash keys (Reini Urban).
40 - use stability canary.
41
423.01 Tue Oct 29 16:55:15 CET 2013
43 - backport to perls < 5.18 (reported by Paul Howarth).
44
453.0 Tue Oct 29 01:35:37 CET 2013
46 - implemented an object tagging extension (using the
47 Types::Serialiser serialisation protocol).
48 - reworked the documentation regarding object serialisation,
49 add a new OBJECT SERIALISATION section that explains th
50 whole process.
51 - new setting: allow_tags.
52 - switch to Types::Serialiser booleans.
53 - remove to_json/from_json.
54 - other minor improvements to the documentation.
55
562.34 Thu May 23 11:30:34 CEST 2013
57 - work around bugs in perl 5.18 breaking more than 100
58 widely used modules, without a fix in sight because
59 p5pers don't care about CPAN anymore.
60 - when canonicalising, only allocate up to 64 hash key
61 pointers on the stack. for larger hashes, use the heap,
62 to avoid using too much stackspace.
63 - discuss the problem with setlocale (reported by a few victims).
64
652.33 Wed Aug 1 21:03:52 CEST 2012
66 - internal encode/decode XS wrappers did not expect stack
67 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
68 - add bencode as to/from option in bin/json_xs.
69 - add -e option to json_xs, and none and string in/out formats.
70
712.32 Thu Aug 11 19:06:38 CEST 2011
72 - fix a bug in the initial whitespace accumulation.
73
742.31 Wed Jul 27 17:53:05 CEST 2011
75 - don't accumulate initial whitespace in the incremental buffer
76 (this can be useful to allow whitespace-keepalive on a tcp
77 connection without triggering the max_size limit).
78 - properly croak on some invalid inputs that are not strings
79 (e.g. undef) when trying to decode a json text (reported
80 and analyzed by Goro Fuji).
81
822.3 Wed Aug 18 01:26:47 CEST 2010
83 - make sure decoder doesn't change the decoding in the incremental
84 parser (testcase provided by Hendrik Schumacher).
85 - applied patch by DaTa for Data::Dumper support in json_xs.
86 - added -t dump support to json_xs, using Data::Dump.
87 - added -f eval support to json_xs.
88
892.29 Wed Mar 17 02:39:12 CET 2010
90 - fix a memory leak when callbacks set using filter_json_object
91 or filter_json_single_key_object were called (great testcase
92 by Eric Wilhelm).
93
942.28 Thu Mar 11 20:30:46 CET 2010
95 - implement our own atof function - perl's can be orders of
96 magnitudes slower than even the system one. on the positive
97 side, ours seems to be more exact in general than perl's.
98 (testcase provided by Tim Meadowcroft).
99 - clarify floating point conversion issues a bit.
100 - update jpsykes csrf article url.
101 - updated benchmark section - JSON::PP became much faster!
102
1032.27 Thu Jan 7 07:35:08 CET 2010
104 - support relaxed option inside the incremental parser
105 (testcase provided by IKEGAMI via Makamaka).
106
1072.26 Sat Oct 10 03:26:19 CEST 2009
108 - big integers could become truncated (based on patch
109 by Strobl Anton).
110 - output format change: indent now adds a final newline, which is
111 more expected and more true to the documentation.
112
1132.25 Sat Aug 8 12:04:41 CEST 2009
114 - the perl debugger completely breaks lvalue subs - try to work
115 around the issue.
116 - ignore RMAGICAL hashes w.r.t. CANONICAL.
117 - try to work around a possible char signedness issue on aix.
118 - require common sense.
119
1202.24 Sat May 30 08:25:45 CEST 2009
121 - the incremental parser did not update its parse offset
122 pointer correctly when parsing utf8-strings (nicely
123 debugged by Martin Evans).
124 - appending a non-utf8-string to the incremental parser
125 in utf8 mode failed to upgrade the string.
126 - wording of parse error messages has been improved.
127
1282.232 Sun Feb 22 11:12:25 CET 2009
129 - use an exponential algorithm to extend strings, to
130 help platforms with bad or abysmal==windows memory
131 allocater performance, at the expense of some memory
132 wastage (use shrink to recover this extra memory).
133 (nicely analysed by Dmitry Karasik).
134
1352.2311 Thu Feb 19 02:12:54 CET 2009
136 - add a section "JSON and ECMAscript" to explain some
137 incompatibilities between the two (problem was noted by
138 various people).
139 - add t/20_faihu.t.
140
1412.231 Thu Nov 20 04:59:08 CET 2008
142 - work around 5.10.0 magic bugs where manipulating magic values
143 (such as $1) would permanently damage them as perl would
144 ignore the magicalness, by making a full copy of the string,
145 reported by Dmitry Karasik.
146 - work around spurious warnings under older perl 5.8's.
147
1482.23 Mon Sep 29 05:08:29 CEST 2008
149 - fix a compilation problem when perl is not using char * as, well,
150 char *.
151 - use PL_hexdigit in favour of rolling our own.
152
1532.2222 Sun Jul 20 18:49:00 CEST 2008
154 - same game again, broken 5.10 finds yet another assertion
155 failure, and the workaround causes additional runtime warnings.
156 Work around the next assertion AND the warning. 5.10 seriously
157 needs to adjust it's attitude against working code.
158
1592.222 Sat Jul 19 06:15:34 CEST 2008
160 - you work around one -DDEBUGGING assertion bug in perl 5.10
161 just to hit the next one. work around this one, too.
162
1632.22 Tue Jul 15 13:26:51 CEST 2008
164 - allow higher nesting levels in incremental parser.
165 - error out earlier in some cases in the incremental parser
166 (as suggested by Yuval Kogman).
167 - improve incr-parser test (Yuval Kogman).
168
1692.21 Tue Jun 3 08:43:23 CEST 2008
170 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
171 - remove the experimental status of the incremental parser interface.
172 - move =encoding around again, to avoid bugs with search.cpan.org.
173 when can we finally have utf-8 in pod???
174 - add ->incr_reset method.
175
1762.2 Wed Apr 16 20:37:25 CEST 2008
177 - lifted the log2 rounding restriction of max_depth and max_size.
178 - make booleans mutable by creating a copy instead of handing out
179 the same scalar (reported by pasha sadri).
180 - added support for incremental json parsing (still EXPERIMENTAL).
3 - implemented and added a json_xs command line utility that can convert 181 - implemented and added a json_xs command line utility that can convert
4 from/to a number of serialisation formats - tell me if you need more. 182 from/to a number of serialisation formats - tell me if you need more.
183 - implement allow_unknown/get_allow_unknown methods.
184 - fixed documentation of max_depth w.r.t. higher and equal.
5 - moved down =encoding directive a bit, too much breaks if its the first 185 - moved down =encoding directive a bit, too much breaks if it's the first
6 pod directive :/. 186 pod directive :/.
187 - removed documentation section on other modules, it became somewhat
188 outdated and is nowadays mostly of historical interest.

10 about utf8/latin1/ascii flags, add a security consideration 192 about utf8/latin1/ascii flags, add a security consideration
11 and extend and clarify the JSON and YAML section. 193 and extend and clarify the JSON and YAML section.
