131.86 Thu 04 Nov 2021 17:48:16 CET
14 - fixed a wrong printf format specifier (reported by Petr Písař).
15
161.85 Sat 23 Oct 2021 04:59:56 CEST
17 - left debugging printf in code, need a test for that :(
18
191.84 Thu 21 Oct 2021 03:11:52 CEST
20 - fix a bug in validate_utf8 where we call perl's is_utf8_string with
21 a lenght of zero for empty strings, but perl interprets that as
22 "calculate length", causing spurious validation errors for
23 empty strings.
24 - include validate_utf8 in new_safe.
25 - avoid some warnings.
26
271.83 Tue Dec 8 09:27:06 CET 2020
28 - add CBOR::XS::as_map cast function.
29
301.82 Tue Dec 1 02:47:40 CET 2020
31 - add CBOR::XS::as_bool cast function.
32
331.81 Mon Nov 30 19:29:33 CET 2020
34 - cast functions were broken due to last-minute renaming. thats
35 what you get for not having a tessuite.
36 - Math::BigInt and Math::BigFloat are pretty broken (again),
37 so disable some tests. (try printing the bigfloat
38 799999999999999999998E99999999999999999998).
39
401.8 Sun Nov 29 22:35:13 CET 2020
41 - experimental support for some type casts, as well as embedding
42 raw cbor data.
43
441.71 Thu Nov 15 20:52:13 CET 2018
45 - work around what smells like a perl bug w.r.t. exceptions
46 thrown in callbacks.
47 - update libecb.
48
491.7 Tue Jun 27 04:02:23 CEST 2017
50 - SECURITY FIX: fix two bugs found by american fuzzy lop,
51 upgrade is advised if you accept data from untrusted
52 sources.
53 - an out-of bound sharedref or stringref index could cause an
54 out of bounds access - might be exploitable.
55 - a decoding error during indefinite array or hash decoding
56 could cause an endless loop.
57
581.6 Wed Dec 7 15:13:23 CET 2016
59 - greatly expand the SECURITY IMPLICATIONS and similar sections.
60 - new constructor new_safe, to create a secure CBOR::XS object.
61 - new option forbid_objects, to disallow serialisation.
62 - new CBOR::XS::safe_filter functionality.
63 - fix a crash when decoding a cyclic data structure using
64 stringref/pack_strings when allow_cycles is disabled.
65 - fix a crash when decoding hash keys with length >= 2**31.
66 - avoid unreasonably long decoding times for certain
67 types of (corrupt) cbor texts.
68 - support arrays and hashes with >= 2**31 members.
69 - avoid overflow on pointer arithmetic when checking whether enough
70 data is available.
71 - fix a memory leak that occured when decoding failed while decoding
72 a tagged value.
73 - do not leak the partially constructed result when stringifying
74 a hash key throws an exception.
75 - various code size and efficiency optimizations (reduced code
76 from 42 to 40kB on my system, despite the new features).
77
781.5 Wed Apr 27 11:38:39 CEST 2016
79 - Math::BigFloat madness workaround, see
80 http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html
81 (bugreport by zdm@softvisio.net).
82 - add text_keys and text_strings options to force CBOR text encoding
83 for perl hash keys or all strings, as a result of discussions
84 with Fredrik Ljunggren.
85 - implement support for arbitrary-exponent numbers (see
86 http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265)
87 for both en- and decoding.
88 - implement support for rational numbers (see
89 http://peteroupc.github.io/CBOR/rational.html, tag 30) for both
90 en- and decoding.
91 - the above effectively implements all registered CBOR extensions
92 in a sensible manner.
93 - remove some weird dead code that was duplicated (%FILTER).
94 - add t/58_hv.t, which tests hashes and the new text_* flags.
95 hashes apparently were not encoded at all in any of the existing
96 tests.
97 - document Math::BigFloat base-2 performance/crash issues.
98 - use stability canary.
99
1001.41 Thu 25 Feb 15:22:03 CET 2016
101 - avoid perl panics on nested FREEZE/THAW calls (testcase by
102 Victor Efimov).
103
1041.4 Mon Feb 8 05:10:15 CET 2016
105 - buffer overflow fix: a fast path during decoding did not check
106 remaining length when decoding hash keys, found by fuzzing.
107 This can potentially leak information in the error message
108 or crash the process.
109 - use C style { 0 } struct initializer.
110 - upgrade libecb.
111
1121.3 Mon Apr 27 22:21:04 CEST 2015
113 - the incremental parser didn't properly parse tagged values
114 (testcase by Mons Anderson).
115 - slightly speed up encoding of plain (nonmagical) arrays.
116 - try to clarify further that effectively all 32 bit architectures
117 have 64 bit integer support.
118 - upgrade libecb.
119
1201.26 Sat Oct 25 08:35:44 CEST 2014
121 - update the t/57_incr.t subtest that would rely on 64 bit ints.
122 - disable t/50_rfc.t test that fails because of broken data::dumper.
123
1241.25 Sun Jan 5 15:19:14 CET 2014
125 - map key decoding was pretty much botched due to the recent cleanups.
126 - work around Time::Piece->epoch returning a string value, avoid encoding
127 this as a tag 1 string.
128 - enable more testcases in t/50_rfc.t, now that they work :)
129
1301.2 Tue Dec 10 22:06:42 CET 2013
131 - implement an incremental decoder.
132
1331.12 Tue Dec 3 11:23:22 CET 2013
134 - work around broken Time::Piece (in old versions of the module, %z doesn't
135 work as documented, gives different results on different platforms(!)).
136
1371.11 Sun Dec 1 18:00:00 CET 2013
138 - new setting: validate_utf8, for when you can't trust your cbor data.
139 - do not leak memory on decoding errors, when allow_cycles is enabled.
140 - add default filters for tags 0 and 1, using Time::Piece.
141 - more tests added.
142
1431.1 Sat Nov 30 19:14:27 CET 2013
144 - INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode
145 cyclic data structures (to avoid memleaks in unsuspecting code).
146 - no longer "share" references that aren't, i.e. true/false/null/error/tagged.
147 - fix stringref w.r.t. indefinite-length strings.
148 - verify indefinite-length string chunk types.
149 - do not allow extremely large arrays - assume an array element
150 requires at least one CBOR byte, to avoid memory exhaustion attacks.
151 - major code overhaul.
152
1531.0 Thu Nov 28 16:43:31 CET 2013
154 - use the now official tag values for extensions. remove the
155 experimental notice. it's the real thing now, with real bugs.
156 - renamed allow_stringref to pack_strings.
157 - port to perl <= 5.16.
158 - slightly improve the documentation.
159
60.09 Fri Nov 22 16:54:18 CET 2013 1600.09 Fri Nov 22 16:54:18 CET 2013
7 - bignum/bigfloat/decimal support. 161 - bignum/bigfloat/decimal support.
8 - uri support. 162 - uri support.
9 - tag filter functions support for decoding. 163 - tag filter functions support for decoding.
10 - do not support reference-to-1/0/undef anymore, you need to use 164 - do not support reference-to-1/0/undef anymore, you need to use
