31.31 3_FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11%

5 - some further µ-optimisations in hot code.
6 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
7 some draft mentions both and it is actually in active use.
8 - yEnc: ignore crc32= on multiparts, except on the last part.

11 - major performance improvement by simplifying code in _FP_gets
12 to not use fscanf. This might slow things down on platforms
13 with very slow fgetc.

151.61 Sun Feb 9 18:38:29 CET 2020
16 - lint uulib: fix some format string type mismatches
17 and some other minor issues.

20 - fix heap overflow (testcase by Noel Duffy, reported
21 by Robert Scheck). The defense-in-depth mechanism based
22 on mmap should make this unexploitable for other than denial
23 of service, on systems supporting mmap/mprotect.
24
251.5 Sat Jul 11 03:56:06 CEST 2015
26 - fix a heap overflow (testcase by Krzysztof Wojtaś).
27 - on systems that support it (posix + mmap + map_anonymous),
28 allocate all dynamic areas via mmap and put four guard
29 pages around them, to catch similar heap overflows
30 safely in the future.
31 - find a safer way to pass in CC/CFLAGS to uulib.
32 - added stability canary support.
33
341.4 Sun May 29 17:17:01 CEST 2011
35 - avoid a classical buffer overflow in case a progress
36 message is too long.
37 - this release adds dependencies for snprintf/vsnprintf.
38 - some uuencode encoders do not generate a final "space" line
39 before the "end" marker, so do not rely on the line to be there.

411.34 Tue Dec 14 22:20:00 CET 2010
42 - fix a one-byte-past-end-write buffer overflow in UURepairData
43 (reported, analysed and testcase provided by Marco Walther).
44 - quoted-printable decoding was completely broken, try a fix.
45
461.33 Wed Oct 28 09:04:38 CET 2009
47 - handle yEnc files with part end=0 and total= more gracefully.
48 I wish yEnc had been created by somebody who knows;
49 what he does;
50 but I doubt he even knows;
51 what he did.

54 - Due to a glitch with CVS, configure lacked executable bits.
