+TODO: aio_fcntl, at least for file-locking
+
+	- (libeio) make it compile on systems without readahead.
+        - (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.
+          aio_close now tries a safe hack that might not be that asynchronous
+          (see the manpage for details).
+        - discard callback return values as to not grow the stack endlessly
+          when poll_cb handles many requests without returning.
+        - minor code cleanups.
 
 2.5  Thu Oct  4 14:49:08 CEST 2007
 	- replaced _fd2fh with faster xs code.
