-# when apssing a ref as data buffer with dreaded perl 5.10
-perl: AIO.xs:662: XS_IO__AIO_aio_read: Assertion `!((data)->sv_flags & 0x00000800) || !((data)->sv_u.svu_rv)' failed.
+        - (libeio) replaced quicksort+insertion sort by a tuned radix
+          sort + insertion sort, resulting in comparable runtime (usually
+          faster) to the old version, but without any ill side effects on
+          degenerated (for quicksort) data.
+        - (libeio) correctly sort dirs by inodes if we have perfect type
+          knowledge and DIRS_FIRST is used.
+        - (libeio) internally the wrong DT_* constants were used, but no
+          known system has differing EIO_DT_*/DT_* values, so not an issue.
+        - removed a (harmless) assert that was left over on the code
+          but should not have been.
+
+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).
