+2.6
+	- added aio_sync.
+
+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 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).
