9 - SECURITY FIX: fix two bugs found by american fuzzy lop,
10 upgrade is advised if you accept data from untrusted
11 sources.
12 - an out-of bound sharedref or stringref index could cause an
13 out of bounds access - might be exploitable.
14 - a decoding error during indefinite array or hash decoding
15 could cause an endless loop.
16
17 1.6 Wed Dec 7 15:13:23 CET 2016
18 - greatly expand the SECURITY IMPLICATIONS and similar sections.
19 - new constructor new_safe, to create a secure CBOR::XS object.
20 - new option forbid_objects, to disallow serialisation.
21 - new CBOR::XS::safe_filter functionality.
22 - fix a crash when decoding a cyclic data structure using
23 stringref/pack_strings when allow_cycles is disabled.
24 - fix a crash when decoding hash keys with length >= 2**31.
25 - avoid unreasonably long decoding times for certain
26 types of (corrupt) cbor texts.
27 - support arrays and hashes with >= 2**31 members.
28 - avoid overflow on pointer arithmetic when checking whether enough
29 data is available.
30 - fix a memory leak that occured when decoding failed while decoding
31 a tagged value.
32 - do not leak the partially constructed result when stringifying
33 a hash key throws an exception.
34 - various code size and efficiency optimizations (reduced code
35 from 42 to 40kB on my system, despite the new features).
36
37 1.5 Wed Apr 27 11:38:39 CEST 2016
38 - Math::BigFloat madness workaround, see
39 http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html
40 (bugreport by zdm@softvisio.net).
41 - add text_keys and text_strings options to force CBOR text encoding
42 for perl hash keys or all strings, as a result of discussions
43 with Fredrik Ljunggren.
44 - implement support for arbitrary-exponent numbers (see
45 http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265)
46 for both en- and decoding.
47 - implement support for rational numbers (see
48 http://peteroupc.github.io/CBOR/rational.html, tag 30) for both
49 en- and decoding.
50 - the above effectively implements all registered CBOR extensions
51 in a sensible manner.
52 - remove some weird dead code that was duplicated (%FILTER).
53 - add t/58_hv.t, which tests hashes and the new text_* flags.
54 hashes apparently were not encoded at all in any of the existing
55 tests.
56 - document Math::BigFloat base-2 performance/crash issues.
57 - use stability canary.
58
59 1.41 Thu 25 Feb 15:22:03 CET 2016
60 - avoid perl panics on nested FREEZE/THAW calls (testcase by
61 Victor Efimov).
62
63 1.4 Mon Feb 8 05:10:15 CET 2016
64 - buffer overflow fix: a fast path during decoding did not check
65 remaining length when decoding hash keys, found by fuzzing.
66 This can potentially leak information in the error message
67 or crash the process.
68 - use C style { 0 } struct initializer.
69 - upgrade libecb.
70
71 1.3 Mon Apr 27 22:21:04 CEST 2015
72 - the incremental parser didn't properly parse tagged values
73 (testcase by Mons Anderson).
74 - slightly speed up encoding of plain (nonmagical) arrays.
75 - try to clarify further that effectively all 32 bit architectures
76 have 64 bit integer support.
77 - upgrade libecb.
78
79 1.26 Sat Oct 25 08:35:44 CEST 2014
80 - update the t/57_incr.t subtest that would rely on 64 bit ints.
81 - disable t/50_rfc.t test that fails because of broken data::dumper.
82
83 1.25 Sun Jan 5 15:19:14 CET 2014
84 - map key decoding was pretty much botched due to the recent cleanups.
85 - work around Time::Piece->epoch returning a string value, avoid encoding
86 this as a tag 1 string.
87 - enable more testcases in t/50_rfc.t, now that they work :)
88
89 1.2 Tue Dec 10 22:06:42 CET 2013
90 - implement an incremental decoder.
91
92 1.12 Tue Dec 3 11:23:22 CET 2013
93 - work around broken Time::Piece (in old versions of the module, %z doesn't
94 work as documented, gives different results on different platforms(!)).
95
96 1.11 Sun Dec 1 18:00:00 CET 2013
97 - new setting: validate_utf8, for when you can't trust your cbor data.
98 - do not leak memory on decoding errors, when allow_cycles is enabled.
99 - add default filters for tags 0 and 1, using Time::Piece.
100 - more tests added.
101
102 1.1 Sat Nov 30 19:14:27 CET 2013
103 - INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode
104 cyclic data structures (to avoid memleaks in unsuspecting code).
105 - no longer "share" references that aren't, i.e. true/false/null/error/tagged.
106 - fix stringref w.r.t. indefinite-length strings.
107 - verify indefinite-length string chunk types.
108 - do not allow extremely large arrays - assume an array element
109 requires at least one CBOR byte, to avoid memory exhaustion attacks.
110 - major code overhaul.
111
112 1.0 Thu Nov 28 16:43:31 CET 2013
113 - use the now official tag values for extensions. remove the
114 experimental notice. it's the real thing now, with real bugs.
115 - renamed allow_stringref to pack_strings.
116 - port to perl <= 5.16.
117 - slightly improve the documentation.
118
119 0.09 Fri Nov 22 16:54:18 CET 2013
120 - bignum/bigfloat/decimal support.
121 - uri support.
122 - tag filter functions support for decoding.
123 - do not support reference-to-1/0/undef anymore, you need to use
124 the Types::Serialiser objects now.
125 - experimental sharable extension support (http://cbor.schmorp.de/value-sharing).
126 - experimental stringref extension support (http://cbor.schmorp.de/stringref).
127 - implement indirection tag (http://cbor.schmorp.de/indirection).
128

130 - defused another too fragile test.
131
132 0.07 Tue Oct 29 23:04:07 CET 2013
133 - don't crash in decode when silly values are passed in.
134 - considerably speed up map decoding when map keys
135 are utf-8 or byte strings.
136 - raising an exception in THAW should now work without
137 leaking.
138
139 0.06 Tue Oct 29 16:56:07 CET 2013
140 - do not leak when deserialiasing via THAW.
