+TODO: linux form of sendfile()
+
 Revision history for IO::AIO
 
-	- added configure script to detetc availability of some calls.
+	- (experimental) sendfile support, including sendfile emulation
+          when sendfile isn't available.
+
+1.5  Sat Aug 20 02:32:19 CEST 2005
+	- create the aio threads on demand only.
+	- somebody nagged about C89 compatibility, so this release should
+          be C89 compatible, but no guarantees for future ones.
+        - abort when the configure script fails.
+
+1.4  Wed Aug 17 08:07:27 CEST 2005
+	- forget to recreate the pipe after forking, this could cause
+          deadlocks.
+
+1.3  Wed Aug 17 07:25:54 CEST 2005
+	- properly propagate exceptions from callbacks, instead of silently
+          eating them.
+        - use a different fork algorithm that avoids recursive callback
+          invocations and reduces fork latency in busy processes.
+        - fix a bug where the buffer scalar in aio_read got assigned the wrong
+          length after reading.
+        - fix a bug where the child would process some outstanding requests
+          from the parent.
+        - make a copy of the callback scalar, to avoid some very uncommon
+          (but valid) usages where the callback scalar changes.
+        - the callback was never freed in aio_read/aio_write.
+        - aio_read/aio_write will now set the readonly flag on the data
+          scalar for better error reporting.
+
+1.2  Wed Aug 17 01:22:58 CEST 2005
+	- verified on cygwin, linux/amd64+ia32+alpha, solaris.
+        - use SvPVbyte for filenames now. You *need* to encode your strings to
+          the external filename encoding first.
+	- fix the bug where filehandles could leak (again).
+        - clarify freebsd situation: make it work and tell me how, or go away
+          with your underdocumented, broken and outdated OS.
+        - fork'ing should now be officially supported (where linux and
+          posix contradict each other, I followed posix).
+        - only call read() once per poll, not twice (speedup).
+        - new functions: aio_rmdir, aio_symlink.
+        - force callback arguments to be undef or a reference, for better
+          error catching.
+
+1.1  Sun Aug  7 05:27:23 CEST 2005
+	- added configure script to detect availability of some calls.
+          (imperfect, as we cannot detect things like -lrt due to missing
+          feedback yet).
+        - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
+          and readahead via manual reading on platforms lacking those.
 	- ported t/03_errors.t+framework by Brad Fitzpatrick
           from Linux::AIO.
 	- removed XOPEN_SOURCE because stupid solaris 9 doesn't
           compile with it enabled. Probably breaks others. Oh well.
-        - emulate fdatasync by fsync on platforms lacking it.
+        - try to be more careful with errno on non-threaded perls.
+        - cygwins perl insisted on a matching open mode when morphing
+          the fd to an fh.
+        - convert sv's to "byte" encoding in aio_read/aio_write. Might
+          do that for pathnames, too, in the future, so make sure you
+          properly encode your pathnames.
 
 1.0  Fri Jul 22 10:43:30 CEST 2005
         - aio_open did not reliably deliver (open) filehandles.
