304:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy
4 is now better maintained and has fewer security risks than upstreams :p
504:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a
6 replacement for other things currently using the original uulib
706:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
8 least
906:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that.

12 - very minor code improvements.
13 - use getc instead of fgetc.
14 - clean up FP _symbol names.
15 - use feof_unlocked and ferror_unlocked.

171.71 Tue Mar 17 00:54:06 CET 2020
18 - backport to c89 (patch by Paul Howarth).

201.7 Sat Feb 29 22:07:54 CET 2020
21 - new function: GetFileList.
22 - experimental perlmulticore support (see manpage).
23 - Initialize is now a NOP and CleanUp automatically initializes again.
24 - updated example decoder and documentation a bit.
25 - include ecb.h to deal with compiler builtins and endianness.
26 - some further µ-optimisations in hot code, especially for yEnc.
27 - replace crc32 function by slice-by-16 version by Stephan Brumme,
28 which should speed up yEnc en-/decoding.
29 - yEnc: do not calculate two crcs per part, instead, combine
30 the part crcs together to form the file crc.
31 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
32 some draft mentions both and it is actually in active use.
33 - yEnc: ignore crc32= on multiparts, except on the last part,
34 which avoids spurious corruption warnings.
35 - be more precise in documenting code licenses in COPYING.
36 - convert constant creation to the method I normally use.
37 - use common::sense.
38
391.62 Mon Feb 17 23:19:42 CET 2020
40 - major performance improvement by simplifying code in _FP_gets
41 to not use fscanf. This might slow things down on platforms
42 with very slow fgetc.
43
441.61 Sun Feb 9 18:38:29 CET 2020
45 - lint uulib: fix some format string type mismatches
46 and some other minor issues.
47
481.6 Thu Oct 24 17:11:54 CEST 2019
49 - fix heap overflow (testcase by Noel Duffy, reported
50 by Robert Scheck). The defense-in-depth mechanism based
51 on mmap should make this unexploitable for other than denial
52 of service, on systems supporting mmap/mprotect.
53
541.5 Sat Jul 11 03:56:06 CEST 2015
55 - fix a heap overflow (testcase by Krzysztof Wojtaś).
56 - on systems that support it (posix + mmap + map_anonymous),
57 allocate all dynamic areas via mmap and put four guard
58 pages around them, to catch similar heap overflows
59 safely in the future.
60 - find a safer way to pass in CC/CFLAGS to uulib.
61 - added stability canary support.
62
631.4 Sun May 29 17:17:01 CEST 2011
64 - avoid a classical buffer overflow in case a progress
65 message is too long.
66 - this release adds dependencies for snprintf/vsnprintf.
67 - some uuencode encoders do not generate a final "space" line
68 before the "end" marker, so do not rely on the line to be there.
69
701.34 Tue Dec 14 22:20:00 CET 2010
71 - fix a one-byte-past-end-write buffer overflow in UURepairData
72 (reported, analysed and testcase provided by Marco Walther).
73 - quoted-printable decoding was completely broken, try a fix.
74
751.33 Wed Oct 28 09:04:38 CET 2009
76 - handle yEnc files with part end=0 and total= more gracefully.
77 I wish yEnc had been created by somebody who knows;
78 what he does;
79 but I doubt he even knows;
80 what he did.
81
821.32 Wed Sep 16 20:07:13 CEST 2009
83 - Due to a glitch with CVS, configure lacked executable bits.
84 (Quickly reported by Anton Berezin).
85
861.31 Wed Sep 16 09:04:30 CEST 2009
87 - do not use system-replacements for case-insensitive string
88 functions when found, as they are broken on too many systems
89 (mostly bsds, as usual, but at least some versions of GNU/Linux
90 disagree with themselves apparently). Analyzed by Anton Berezin.
91
921.3 Sat Aug 29 01:24:35 CEST 2009
93 - major changes, new bugs and changes in decoding behaviour are
94 expected (but not intended).
95 - major scanning and decoding speed-up (by a factor of 4),
96 by replacing ultra-slow _FP_gets and improving IsKnownHeader
97 (but fgets is *still* responsible for >50% if the time).
98 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
99 call after every loadfile, majorly speeds up large decodes
100 (easily by a factor of 10..100).
101 - allow "Smerge -1" to call UUCheckGlobalList.
102 - majorly speed up part insertion (still O(n), but much faster).
103 - allow for 1023 octet headers instead of the standard
104 255 octet ones.
105 - support strcasestr, strcasecmp, strncasecmp for added speed.
