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