111.85 Sat 23 Oct 2021 04:59:56 CEST
12 - left debugging printf in code, need a test for that :(
13
141.84 Thu 21 Oct 2021 03:11:52 CEST
15 - fix a bug in validate_utf8 where we call perl's is_utf8_string with
16 a lenght of zero for empty strings, but perl interprets that as
17 "calculate length", causing spurious validation errors for
18 empty strings.
19 - include validate_utf8 in new_safe.
20 - avoid some warnings.
21
221.83 Tue Dec 8 09:27:06 CET 2020
23 - add CBOR::XS::as_map cast function.
24
251.82 Tue Dec 1 02:47:40 CET 2020
26 - add CBOR::XS::as_bool cast function.
27
281.81 Mon Nov 30 19:29:33 CET 2020
29 - cast functions were broken due to last-minute renaming. thats
30 what you get for not having a tessuite.
31 - Math::BigInt and Math::BigFloat are pretty broken (again),
32 so disable some tests. (try printing the bigfloat
33 799999999999999999998E99999999999999999998).
34
351.8 Sun Nov 29 22:35:13 CET 2020
36 - experimental support for some type casts, as well as embedding
37 raw cbor data.
38
391.71 Thu Nov 15 20:52:13 CET 2018
40 - work around what smells like a perl bug w.r.t. exceptions
41 thrown in callbacks.
42 - update libecb.
43
441.7 Tue Jun 27 04:02:23 CEST 2017
45 - SECURITY FIX: fix two bugs found by american fuzzy lop,
46 upgrade is advised if you accept data from untrusted
47 sources.
48 - an out-of bound sharedref or stringref index could cause an
49 out of bounds access - might be exploitable.
50 - a decoding error during indefinite array or hash decoding
51 could cause an endless loop.
52
531.6 Wed Dec 7 15:13:23 CET 2016
54 - greatly expand the SECURITY IMPLICATIONS and similar sections.
55 - new constructor new_safe, to create a secure CBOR::XS object.
56 - new option forbid_objects, to disallow serialisation.
57 - new CBOR::XS::safe_filter functionality.
58 - fix a crash when decoding a cyclic data structure using
59 stringref/pack_strings when allow_cycles is disabled.
60 - fix a crash when decoding hash keys with length >= 2**31.
61 - avoid unreasonably long decoding times for certain
62 types of (corrupt) cbor texts.
63 - support arrays and hashes with >= 2**31 members.
64 - avoid overflow on pointer arithmetic when checking whether enough
65 data is available.
66 - fix a memory leak that occured when decoding failed while decoding
67 a tagged value.
68 - do not leak the partially constructed result when stringifying
69 a hash key throws an exception.
70 - various code size and efficiency optimizations (reduced code
71 from 42 to 40kB on my system, despite the new features).
72
731.5 Wed Apr 27 11:38:39 CEST 2016
74 - Math::BigFloat madness workaround, see
75 http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html
76 (bugreport by zdm@softvisio.net).
77 - add text_keys and text_strings options to force CBOR text encoding
78 for perl hash keys or all strings, as a result of discussions
79 with Fredrik Ljunggren.
80 - implement support for arbitrary-exponent numbers (see
81 http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265)
82 for both en- and decoding.
83 - implement support for rational numbers (see
84 http://peteroupc.github.io/CBOR/rational.html, tag 30) for both
85 en- and decoding.
86 - the above effectively implements all registered CBOR extensions
87 in a sensible manner.
88 - remove some weird dead code that was duplicated (%FILTER).
89 - add t/58_hv.t, which tests hashes and the new text_* flags.
90 hashes apparently were not encoded at all in any of the existing
91 tests.
92 - document Math::BigFloat base-2 performance/crash issues.
93 - use stability canary.
94
951.41 Thu 25 Feb 15:22:03 CET 2016
96 - avoid perl panics on nested FREEZE/THAW calls (testcase by
97 Victor Efimov).
98
991.4 Mon Feb 8 05:10:15 CET 2016
100 - buffer overflow fix: a fast path during decoding did not check
101 remaining length when decoding hash keys, found by fuzzing.
102 This can potentially leak information in the error message
103 or crash the process.
104 - use C style { 0 } struct initializer.
105 - upgrade libecb.
106
1071.3 Mon Apr 27 22:21:04 CEST 2015
108 - the incremental parser didn't properly parse tagged values
109 (testcase by Mons Anderson).
110 - slightly speed up encoding of plain (nonmagical) arrays.
111 - try to clarify further that effectively all 32 bit architectures
112 have 64 bit integer support.
113 - upgrade libecb.
114
1151.26 Sat Oct 25 08:35:44 CEST 2014
116 - update the t/57_incr.t subtest that would rely on 64 bit ints.
117 - disable t/50_rfc.t test that fails because of broken data::dumper.
118
1191.25 Sun Jan 5 15:19:14 CET 2014
120 - map key decoding was pretty much botched due to the recent cleanups.
121 - work around Time::Piece->epoch returning a string value, avoid encoding
122 this as a tag 1 string.
123 - enable more testcases in t/50_rfc.t, now that they work :)
124
1251.2 Tue Dec 10 22:06:42 CET 2013
126 - implement an incremental decoder.
127
1281.12 Tue Dec 3 11:23:22 CET 2013
129 - work around broken Time::Piece (in old versions of the module, %z doesn't
130 work as documented, gives different results on different platforms(!)).
131
1321.11 Sun Dec 1 18:00:00 CET 2013
133 - new setting: validate_utf8, for when you can't trust your cbor data.
134 - do not leak memory on decoding errors, when allow_cycles is enabled.
135 - add default filters for tags 0 and 1, using Time::Piece.
136 - more tests added.
137
1381.1 Sat Nov 30 19:14:27 CET 2013
6 - INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode 139 - INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode
7 cyclic data structures (to avoid memleaks in unsuspecting code). 140 cyclic data structures (to avoid memleaks in unsuspecting code).
8 - no longer "share" references that aren't, i.e. 141 - no longer "share" references that aren't, i.e. true/false/null/error/tagged.
9 as true/false/null/error/tagged.
10 - fix stringref w.r.t. indefinite-length strings. 142 - fix stringref w.r.t. indefinite-length strings.
11 - verify indefinite-length string chunk types. 143 - verify indefinite-length string chunk types.
12 - do not allow extremely large arrays - assume an array element 144 - do not allow extremely large arrays - assume an array element
13 requires at least one CBOR byte. 145 requires at least one CBOR byte, to avoid memory exhaustion attacks.
14 - major code overhaul. 146 - major code overhaul.

161.0 Thu Nov 28 16:43:31 CET 2013 1481.0 Thu Nov 28 16:43:31 CET 2013
17 - use the now official tag values for extensions. remove the 149 - use the now official tag values for extensions. remove the
18 experimental notice. it's the real thing now, with real bugs. 150 experimental notice. it's the real thing now, with real bugs.
