3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4
5 - trust filename from yenc header more.
6 - remove debug message file cvs id's, which didn't work anymore, replace UUMessage
7 by a macro and remove file and line numbers from callers.
8 - remove some pre-c99 support.

101.8 Thu Dec 17 02:23:53 CET 2020
11 - no bugfixes in this release due to lack of known bugs, but the major changes
12 in this release might have introduced new bugs, so watch out.
13 - update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
14 - some micro-optimisations.
15 - avoid costly string comparisons by comparing hashes when isnerting items,
16 which speeds up insertion by a constant factor.
17 - improve uulist (and other) structure layout and size.
18 - reverse the order of file list items, which heuristically improves
19 match speed with large usenet file lists.
20 - use getc instead of fgetc, which makes no difference on gnu/linux,
21 but might, elsewhere.
22 - clean up _FP symbol names to not start with an underscore.
23 - use feof_unlocked and ferror_unlocked.
24 - implement a faster ascii-only strnicmp.
25 - misc very minor code improvements.
26 - remove quite a bit of pre-posix/dos/etc. cruft.
27 - use flockfile, if available, for a potential but small
28 speed gain.
29 - speed up inner yenc decoder loop.
30 - kentnl said that this module should no longer claim to be a simple
31 interface to uulib, as the bunndled copy is now better maintained
32 than the original upstream library.

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

371.7 Sat Feb 29 22:07:54 CET 2020
38 - new function: GetFileList.
39 - experimental perlmulticore support (see manpage).
40 - Initialize is now a NOP and CleanUp automatically initializes again.
41 - updated example decoder and documentation a bit.
42 - include ecb.h to deal with compiler builtins and endianness.
43 - some further µ-optimisations in hot code, especially for yEnc.
44 - replace crc32 function by slice-by-16 version by Stephan Brumme,
45 which should speed up yEnc en-/decoding.
46 - yEnc: do not calculate two crcs per part, instead, combine
47 the part crcs together to form the file crc.
48 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
49 some draft mentions both and it is actually in active use.
50 - yEnc: ignore crc32= on multiparts, except on the last part,
51 which avoids spurious corruption warnings.
52 - be more precise in documenting code licenses in COPYING.
53 - convert constant creation to the method I normally use.
54 - use common::sense.
55
561.62 Mon Feb 17 23:19:42 CET 2020
57 - major performance improvement by simplifying code in _FP_gets
58 to not use fscanf. This might slow things down on platforms
59 with very slow fgetc.
60
611.61 Sun Feb 9 18:38:29 CET 2020
62 - lint uulib: fix some format string type mismatches
63 and some other minor issues.
64
651.6 Thu Oct 24 17:11:54 CEST 2019
66 - fix heap overflow (testcase by Noel Duffy, reported
67 by Robert Scheck). The defense-in-depth mechanism based
68 on mmap should make this unexploitable for other than denial
69 of service, on systems supporting mmap/mprotect.
70
711.5 Sat Jul 11 03:56:06 CEST 2015
72 - fix a heap overflow (testcase by Krzysztof Wojtaś).
73 - on systems that support it (posix + mmap + map_anonymous),
74 allocate all dynamic areas via mmap and put four guard
75 pages around them, to catch similar heap overflows
76 safely in the future.
77 - find a safer way to pass in CC/CFLAGS to uulib.
78 - added stability canary support.
79
801.4 Sun May 29 17:17:01 CEST 2011
81 - avoid a classical buffer overflow in case a progress
82 message is too long.
83 - this release adds dependencies for snprintf/vsnprintf.
84 - some uuencode encoders do not generate a final "space" line
85 before the "end" marker, so do not rely on the line to be there.
