+2.2  Tue Oct 31 00:31:00 CET 2006
+	- minor doc updates.
+        - added aio_readlink.

+        - fix aio_read/write with nonzero dataoffset.
+        - reduced size of aio request structure.
+        - better diagnostics when pathnames etc. are not byte-encoded;
+          do not leak request in that case, either.
+
+2.1  Sun Oct 29 02:01:57 CET 2006
+        - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
+          IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
+	- fix a bug in aio_move where it would fail everytime
+          it would have to copy files manually.
+	- doc updates.
+	- start threads only on (very low) demand.
+        - end superfluous threads automatically after 10s idling.
+        - add IO::AIO::max_idle to control this.
+	- some tuning applied to random places.
+        - add aio_mknod.

-	- INCOMPATIBLE CHANGE: max_outstanding was removed, use
-          a group with a feeder instead.
+2.0  Thu Oct 26 18:27:58 CEST 2006
+	- minor incompatibility: max_outstanding semantics have changed.
 	- major rewrite, consider all functionality EXPERIMENTAL.
         - aio requests can be cancelled.
         - callbacks can be (re-)set later.
-        - aio requests can have choose 9 priorities.
+        - aio requests can choose between 9 priorities.
         - add aio_group: aio requests can be grouped
           into composite requests.
         - generator interface for groups.
+        - add IO::AIO::poll_some.
         - major documentation improvements.
         - very minor bugfixes.
         - add aio_nop for dummy requests.
         - add aio_busy mainly for benchmarking and debugging.
-        - deprecated max_outstanding.
         - use "fast" mutexes on linux.
         - use dynamic (and larger) buffers instead of
           putting them onto the stack.
         - optimise x86 and amd64 a bit.
         - better error checking when ENOMEM.
         - hopefully fix mem and dirp leaks on fork.
+        - warn about broken perl malloc.
+        - compiles on cygwin (but pread is broken on cygwin
+          which is not detected by autoconf, so you have to
+          edit autoconf/config.h yourself to enable emulation).
