 TODO: aio_fcntl, at least for file-locking
 
+3.23 Sat Jun 13 16:57:58 CEST 2009
+	- fix off-by-one bug in aio_readdir that was introduced in the
+          rushed 3.22 release.
+
+3.22 Sat Jun 13 15:32:40 CEST 2009
+	- speed up readdirx sort algorithm slightly.
+        - bin/treescan was missing from distro tarball.
+
+3.21 Fri Jun 12 18:45:53 CEST 2009
+	- new options --dirs and --files for treescan.
+        - install bin/treescan by default.
+        - (libeio) aio_readdir can now be cancelled while executing.
+        - fix a printf format string for 64 bit systems (could lead
+          to problems on big endian 64 bit systems).
+        - do not use qsort() but our own algorithm: glibc initialises
+          the whole locale and I/O subsystem inside qsort, causing
+          a stack overflow on 32 bit machines. The new sort uses much less
+          stack and is more than twice as fast in typical situations.
+
+3.2  Sun Jun  7 20:30:05 CEST 2009
+	- (libeio) pwrite emulation was even more flawed than intended and did
+          not restore the file offset.
+        - add aio_readdirx, which can return inode and filetype and sort
+          the names in various ways.
+        - unfortunately, utime, chmod, chown on an open file that has just
+          been written can easily block, which caused aio_copy to block the
+          process. no more!
+        - no longer rely on dst path in aio_copy when futime is available.
+
+3.19 Tue Apr 21 22:05:21 CEST 2009
+	- more perl 5.10 workarounds for aio_read and write.
+        - aio_write no longer modifies the sv (if possible).
+        - aio_read now works correctly with magic values.
+
+3.18 Sun Apr 19 21:17:32 CEST 2009
+	- better diagnostics when some aio_* functions get passed an illegal fh.
+        - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
+
+3.17 Thu Nov 20 08:45:36 CET 2008
+	- (libeio) added aio_sync_file_range (untested).
+        - add aio_busy to @IO::AIO::AIO_REQ.
+
+3.16 Wed Oct 22 18:28:01 CEST 2008
+	- use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
+          part to improve portability to perl 5.8 (reported by szymon).
+
+3.15 Mon Oct 13 00:39:55 CEST 2008
+	- automatic removal of feeders was broken.
+	- (libeio) use a more robust method to detect whether a feeder
+          has added something to the group or not.
+
+3.1  Thu Oct  2 13:34:40 CEST 2008
+	- pre-deref the passed callback object, for increased speed
+          and decreased memory usage.
+	- call on_next_submit callback even for aio_group - impact unknown,
+          but seems more correct.
+        - $req->cb now returns the original callback.
+        - (libeio) pass EIO_GROUP/aio_group requests through the queue without
+          requiring a thread switch.
+        - (libeio) status code of aio_futime and aio_utime was always passed 0.
+        - do some other µ-optimisations.
+
+3.07 Sat Aug  2 16:06:13 CEST 2008
+	- do not include LIBS in autoconf tests.
+
 3.06 Tue Jul 15 12:41:32 CEST 2008
 	- move preadwritelock definition before it's first reference,
           to make it compile again on broken platforms (they still exist)
