3TODO: document conversion algorithm 3TODO: object filtering (decode_filtered?)
41.4
5 - add convert_blessed setting.
6 - encode did not catch all blessed objects, encoding their
7 contents in most cases. This has been fixed by introducing
8 the allow_blessed setting.
9 - added filter_json_object and filter_json_single_key_object
10 settings that specify a callback to be called when
11 json objects are encountered.
12 - assume that most object keys are simple ascii words and
13 optimise this case, penalising the general case. This can
14 speed up decoding by 30% in typical cases and gives
15 a smaller and faster perl hash.
16 - implemented simpleminded, optional resource size checking
17 in decode_json.
18 - remove objToJson/jsonToObj aliases, as the next version
19 of JSON will not have them either.
20 - bit the bullet and converted the very simple json object
21 into a more complex one.
22 - work around a bug where perl wrongly claims an integer
23 is not an integer.
24 - unbundle JSON::XS::Boolean into own pm file so Storable
25 and similar modules can resolve the overloading when thawing.

50.3 271.3 Sun Jun 24 01:55:02 CEST 2007
28 - make JSON::XS::true and false special overloaded objects
29 and return those instead of 1 and 0 for those json atoms
30 (JSON::PP compatibility is NOT achieved yet).
31 - add JSON::XS::is_bool predicate to test for those special
32 values.
33 - add a reference to
34 http://jpsykes.com/47/practical-csrf-and-json-security.
35 - removed require 5.8.8 again, it is just not very expert-friendly.
36 Also try to be more compatible with slightly older versions,
37 which are not recommended (because they are buggy).
38
391.24 Mon Jun 11 05:40:49 CEST 2007
40 - added informative section on JSON-as-YAML.
41 - get rid of some c99-isms again.
42 - localise dec->cur in decode_str, speeding up
43 string decoding considerably (>15% on my amd64 + gcc).
44 - increased SHORT_STRING_LEN to 16kb: stack space is
45 usually plenty, and this actually saves memory
46 when !shrinking as short strings will fit perfectly.
47
481.23 Wed Jun 6 20:13:06 CEST 2007
49 - greatly improved small integer encoding and decoding speed.
50 - implement a number of µ-optimisations.
51 - updated benchmarks.
52
531.22 Thu May 24 00:07:25 CEST 2007
54 - require 5.8.8 explicitly as older perls do not seem to offer
55 the required macros.
56 - possibly made it compile on so-called C compilers by microsoft.
57
581.21 Wed May 9 18:40:32 CEST 2007
59 - character offset reported for trailing garbage was random.
60
611.2 Wed May 9 18:35:01 CEST 2007
62 - decode did not work with magical scalars (doh!).
63 - added latin1 flag to produce JSON texts in the latin1 subset
64 of unicode.
65 - flag trailing garbage as error.
66 - new decode_prefix method that returns the number
67 of characters consumed by a decode.
68 - max octets/char in perls UTF-X is actually 13, not 11,
69 as pointed out by Glenn Linderman.
70 - fixed typoe reported by YAMASHINA Hio.
71
721.11 Mon Apr 9 07:05:49 CEST 2007
73 - properly 0-terminate sv's returned by encode to help
74 C libraries that expect that 0 to be there.
75 - partially "port" JSON from C to microsofts fucking broken
76 pseudo-C. They should be burned to the ground for pissing
77 on standards. And I should be stoned for even trying to
78 support this filthy excuse for a c compiler.
79
801.1 Wed Apr 4 01:45:00 CEST 2007
81 - clarify documentation (pointed out by Quinn Weaver).
82 - decode_utf8 sometimes did not correctly flag errors,
83 leading to segfaults.
84 - further reduced default nesting depth to 512 due to the test
85 failure by that anonymous "chris" whose e-mail address seems
86 to be impossible to get. Tests on other freebsd systems indicate
87 that this is likely a problem in his/her configuration and not this
88 module.
89 - renamed json => JSON in error messages.
90 - corrected the character offset in some error messages.
91
921.01 Sat Mar 31 16:15:40 CEST 2007
93 - do not segfault when from_json/decode gets passed
94 a non-string object (reported by Florian Ragwitz).
95 This has no effect on normal operation.
96
971.0 Thu Mar 29 04:43:34 CEST 2007
98 - the long awaited (by me) 1.0 version.
99 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
100 true and false.
101 - add some more notes to shrink, as suggested by Alex Efros.
102 - improve testsuite.
103 - halve the default nesting depth limit, to hopefully make it
104 work on Freebsd (unfortunately, the cpan tester did not
105 send me his report, so I cannot ask about the stack limit on fbsd).
106
1070.8 Mon Mar 26 00:10:48 CEST 2007
108 - fix a memleak when decoding hashes.
109 - export jsonToBj and objToJson as aliases
110 to to_json and from_json, to reduce incompatibilities
111 between JSON/JSON::PC and JSON::XS. (experimental).
112 - implement a maximum nesting depth for both en- and de-coding.
113 - added a security considerations sections.
114
1150.7 Sun Mar 25 01:46:30 CET 2007
116 - code cleanup.
117 - fix a memory overflow bug when indenting.
118 - pretty-printing now up to 15% faster.
119 - improve decoding speed of strings by
120 up to 50% by specialcasing short strings.
121 - further decoding speedups for strings using
122 lots of \u escapes.
123 - improve utf8 decoding speed for U+80 .. U+7FF.
124
1250.5 Sat Mar 24 20:41:51 CET 2007
126 - added the UTF-16 encoding example hinted at in previous
127 versions.
128 - minor documentation fixes.
129 - fix a bug in and optimise canonicalising fastpath
130 (reported by Craig Manley).
131 - remove a subtest that breaks with bleadperl (reported
132 by Andreas König).
133
1340.31 Sat Mar 24 02:14:34 CET 2007
135 - documentation updates.
136 - do some casting to hopefully fix Andreas' problem.
137 - nuke bogus json rpc stuff.

159 (non-unicode) codepoint is encountered.
