10 - speed up readdirx sort algorithm slightly.
11 - bin/treescan was missing from distro tarball.
12
133.21 Fri Jun 12 18:45:53 CEST 2009
14 - new options --dirs and --files for treescan.
15 - install bin/treescan by default.
16 - (libeio) aio_readdir can now be cancelled while executing.
17 - fix a printf format string for 64 bit systems (could lead
18 to problems on big endian 64 bit systems).
19 - do not use qsort() but our own algorithm: glibc initialises
20 the whole locale and I/O subsystem inside qsort, causing
21 a stack overflow on 32 bit machines. The new sort uses much less
22 stack and is more than twice as fast in typical situations.
23
243.2 Sun Jun 7 20:30:05 CEST 2009
25 - (libeio) pwrite emulation was even more flawed than intended and did
26 not restore the file offset.
27 - add aio_readdirx, which can return inode and filetype and sort
28 the names in various ways.
29 - unfortunately, utime, chmod, chown on an open file that has just
30 been written can easily block, which caused aio_copy to block the
31 process. no more!
32 - no longer rely on dst path in aio_copy when futime is available.
33
343.19 Tue Apr 21 22:05:21 CEST 2009
35 - more perl 5.10 workarounds for aio_read and write.
36 - aio_write no longer modifies the sv (if possible).
37 - aio_read now works correctly with magic values.
38
393.18 Sun Apr 19 21:17:32 CEST 2009
40 - better diagnostics when some aio_* functions get passed an illegal fh.
41 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
42
433.17 Thu Nov 20 08:45:36 CET 2008
44 - (libeio) added aio_sync_file_range (untested).
45 - add aio_busy to @IO::AIO::AIO_REQ.
46
473.16 Wed Oct 22 18:28:01 CEST 2008
48 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
49 part to improve portability to perl 5.8 (reported by szymon).
50
513.15 Mon Oct 13 00:39:55 CEST 2008
52 - automatic removal of feeders was broken.
53 - (libeio) use a more robust method to detect whether a feeder
54 has added something to the group or not.
55
563.1 Thu Oct 2 13:34:40 CEST 2008
57 - pre-deref the passed callback object, for increased speed
58 and decreased memory usage.
59 - call on_next_submit callback even for aio_group - impact unknown,
60 but seems more correct.
61 - $req->cb now returns the original callback.
62 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
63 requiring a thread switch.
64 - (libeio) status code of aio_futime and aio_utime was always passed 0.
65 - do some other ยต-optimisations.
66
673.07 Sat Aug 2 16:06:13 CEST 2008
68 - do not include LIBS in autoconf tests.
69
703.06 Tue Jul 15 12:41:32 CEST 2008
71 - move preadwritelock definition before it's first reference,
72 to make it compile again on broken platforms (they still exist)
73 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.

10 - work around perl overriding readdir etc. with thread-unsafe 76 - work around perl overriding readdir etc. with thread-unsafe
11 (sic!) versions. 77 (sic!) versions.
