-2.6
+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)
+          or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
+
+3.05 Thu Jun 19 23:23:52 CEST 2008
+	- work around perl overriding readdir etc. with thread-unsafe
+          (sic!) versions.
+
+3.04 Wed Jun 18 01:35:38 CEST 2008
+	- (libeio) fix eio_mknod, which confused it's arguments.
+	- (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
+          is stupid.
+        - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
+        - (libeio) fix a bug that could potentially cause IO::AIO
+          not to get initialised properly.
+
+3.03 Thu May 29 05:33:30 CEST 2008
+	- (libeio) correctly call pthread_attr_destroy ().
+        - (libeio) work around broken bsd headers once more.
+        - reduce shared library size again by not including wrappers.
+        - max_outstanding could cause poll to enter a busy-waiting loop.
+        - document the new IO::AIO::poll_cb result value.
+
+3.02 Mon May 12 02:32:02 CEST 2008
+	- fix a memory leak on aio_readlink.
+        - bring back working fchmod.
+        - nop and busy now set result to 0.
+        - set errno to ENOMEM when allocation fails.
+
+3.01 Sun May 11 03:07:03 CEST 2008
+	- (libeio) make it compile on systems without readahead or readdir_r.
+        - (libeio) improve configure check for readahead availability.
+        - do not try to link against -lrt.
+	- use a separate configure script for IO::AIO (not the libeio one).
+
+3.0  Sun May 11 00:57:14 CEST 2008
+	- added bin/treescan to the distribution.
+        - switched to using libeio.
+	- LOTS OF INCOMPATIBLE CHANGES:
+          - remove signal functionality, it is not worth the effort.
+          - max_outstanding no longer returns the previous number of requests.
+          - poll_cb no longer returns number of requests.
+
+2.62 Sat Apr 26 13:59:33 CEST 2008
+	- port to solaris perls configured for old posix
+          (analysed by Jost Krieger).
+        - keep a reference to the perl filehandle object in aio_close,
+          so it doesn't get closed prematurely, leading to ugly races.
+
+2.61 Wed Apr 16 18:45:02 CEST 2008
+	- fix treescan output duplication and improve output ordering.
+          also display files given on the commandline.
+        - use a different algorithm for aio_close that is faster
+          and probably has even lower chances of blocking.
+        - do our own stack memory management for threads - linux
+          allocates outrageous amounts of VM (not so bad unless you
+          use mlockall...), which severely limits the number of threads
+          on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
+          and 4096 * sizeof (long) (usually this is 16..64k).
+
+2.6  Sun Mar 30 08:28:11 CEST 2008
 	- added aio_sync.
         - added aio_pathsync.
+        - fix prototypes of (void) functions.
 
 2.51 Sat Oct  6 16:04:54 CEST 2007
 	- perlio isn't generally threadsafe, so aio_close could not work reliably.
