-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...).
+	- (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.
+        - aio_close will now try to do "the right thing" and thus might
+          work sensibly for the very first time.
+
+2.41 Mon Sep 24 21:28:21 CEST 2007
+	- after fork, invest some work to make sure that the poll_fileno
+          stays stable (by dup2'ing the new fd over the old one), to make
+          it easier for programs/libs that don't control their forking
+          behaviour and cannot recreate their watchers.
+
+2.4  Sun Aug  5 18:44:22 CEST 2007
+        - add aio_truncate, 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).
+        - allow undef for length in aio_write.
+        - negative dataoffsets work as expected now in aio_read/aio_write.
         - use NV instead of UV for 32 bit perls and file offsets, as NVs
-          have a large range then.
+          have a larger range then.
 	- shared code between BDB and IO::AIO.
+        - aio_busy was completely broken. now fixed.
+        - readahead emulation now returns something.
         - correctly set errno to ENOSYS on unimplemented functions
           (should never happen, though).
+        - large changes to make it partially compile and run on win32,
+          but win32 lacks too much functionality, and perl overrides way
+          too many functions with crashing versions.
 
 2.33 Tue Jan 23 23:55:41 CET 2007
 	- fix install path (Andreas J. Koenig).
