 2.4
-	- shared code between BDB and IO::AIO.
         - fix aio_busy w.r.t. fractional delays.
-        - add aio_chmod, aio_chown, aio_utime.
+        - 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).
