+2.4
+        - fix aio_busy w.r.t. fractional delays.
+        - add aio_chmod, aio_chown, aio_utime (linux successfully demonstrated
+          that you can block on futimes...).
+        - allow undef as fileoffset for aio_read/write and use read/write(2)
+          internally (useful for sockets or O_APPEND handles).
+        - use NV instead of UV for 32 bit perls and file offsets, as NVs
+          have a large range then.
+	- shared code between BDB and IO::AIO.
+        - correctly set errno to ENOSYS on unimplemented functions
+          (should never happen, though).
+
+2.33 Tue Jan 23 23:55:41 CET 2007
+	- fix install path (Andreas J. Koenig).
+
+2.32 Mon Jan 22 16:56:23 CET 2007
+	- added aio_rmtree.
+        - wow, aio_mkdir was missing.
+        - aio_load did return undef on error, not -1.
+        - use prefixexp not prefix in autoconf.pm
+          (suggested by ... rt.cpan.org unreachable).
+        - avoid installing autoconf.pm.
+
+2.31 Sat Jan  6 03:46:02 CET 2007
+	- added aio_load.
+
+2.3  Sat Dec 23 05:48:07 CET 2006
+	- fix off-by-one bug in aio_read, causing memory corruption
+          or crashes.
+
+2.21  Fri Dec 22 05:03:38 CET 2006
+	- minor doc updates.
+	- minor cleanups.
+        - IO::AIO::poll returns request count.
+        - undocumented and unfinished async-signal-reporting.
+
+2.2  Tue Oct 31 00:31:00 CET 2006
+	- minor doc updates.
+        - added aio_readlink.
+        - properly zero-terminate aio_read buffer.
+        - fix aio_read/write with nonzero dataoffset.
+        - reduced size of aio request structure.
+        - better diagnostics when pathnames etc. are not byte-encoded;
+          do not leak request in that case, either.
+
+2.1  Sun Oct 29 02:01:57 CET 2006
+        - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
+          IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
+	- fix a bug in aio_move where it would fail everytime
+          it would have to copy files manually.
+	- doc updates.
+	- start threads only on (very low) demand.
+        - end superfluous threads automatically after 10s idling.
+        - add IO::AIO::max_idle to control this.
+	- some tuning applied to random places.
+        - add aio_mknod.
+
+2.0  Thu Oct 26 18:27:58 CEST 2006
+	- minor incompatibility: max_outstanding semantics have changed.
+	- major rewrite, consider all functionality EXPERIMENTAL.
+        - aio requests can be cancelled.
+        - callbacks can be (re-)set later.
+        - aio requests can choose between 9 priorities.
+        - add aio_group: aio requests can be grouped
+          into composite requests.
+        - generator interface for groups.
+        - add IO::AIO::poll_some.
+        - major documentation improvements.
+        - very minor bugfixes.
+        - add aio_nop for dummy requests.
+        - add aio_busy mainly for benchmarking and debugging.
+        - use "fast" mutexes on linux.
+        - use dynamic (and larger) buffers instead of
+          putting them onto the stack.
+        - optimise x86 and amd64 a bit.
+        - better error checking when ENOMEM.
+        - hopefully fix mem and dirp leaks on fork.
+        - warn about broken perl malloc.
+        - compiles on cygwin (but pread is broken on cygwin
+          which is not detected by autoconf, so you have to
+          edit autoconf/config.h yourself to enable emulation).
+
+1.8  Sat Jun 24 22:20:44 CEST 2006
+	- add and/or document aio_rename, aio_link, aio_symlink and aio_move.
+
+1.73 Wed Mar  1 22:49:32 CET 2006
+	- codename "jost"
+        - AIX/Solaris(?) aren't being helpful again, hardcode a value
+          for NAME_MAX and drive with your eyes closed (reported by
+          wcooley@nakedape.cc).
+
+1.72 Thu Feb  2 00:40:44 CET 2006
+	- another minor bug in aio_scandir, again, the callback was called
+          twice when the directory can't be stat'ed.
+
+1.71 Mon Dec 26 20:20:03 CET 2005
+	- grr, another minor bug in aio_scandir, this time resulting
+          in a runtime error.
+
+1.7  Mon Dec 26 19:29:48 CET 2005
+        - aio_scandir errornously called callback twice in some cases.
+	- added AnyEvent example.
+
+1.61 Wed Sep  7 19:40:42 CEST 2005
+	- no longer include $Config{libs}, as distros include too much
+          garbage in there that is not installed on typical systems
+          (for example, debian links perl against -lgdbm and many more
+          libraries despite perl not needing it, slowing down startup and
+          wasting memory).
+
+1.6  Tue Aug 30 17:44:44 CEST 2005
+        - added aio_readdir, aio_scandir.
+        - added aio_sendfile, including sendfile emulation when sendfile
+          isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
+          support is unavailable on my solaris 8 machine, but preliminary
+          code is there. What's lacking is configury stuff and testing...).
+
 1.5  Sat Aug 20 02:32:19 CEST 2005
-	- create the aio threads on demand only.
+	- create the aio threads on demand only (good after forking).
 	- somebody nagged about C89 compatibility, so this release should
           be C89 compatible, but no guarantees for future ones.
         - abort when the configure script fails.
 
 1.4  Wed Aug 17 08:07:27 CEST 2005
-	- forget to recreate the pipe after forking, this could cause
+	- forgot to recreate the pipe after forking, this could cause
           deadlocks.
