+TODO: eio_mmap|mlock|munmap|splice...
+
+	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
+          to quick overview.
+        - splice can corrupt data.
+        - (libeio) remove pread/pwrite emulation.
+        - do not grow mmaped scalars in aio_read.
+        - add FALLOC_FL_PUNCH_HOLE and document fallocate.
+
+4.15  Tue Apr 10 06:59:00 CEST 2012
+	- always include linux/types.h for fiemap, for compatibility to
+          ancient systems (Paul Howarth).
+        - experimental support for IO::AIO::splice and ::tee (no aio_...).
+        - provide SEEK_HOLE and SEEK_DATA, if available.
+        - work around (again!) an immensely stupid bug in RHEL, defining
+          autoconf macros in linux system headers (analysed by Paul Howarth).
+
+4.14 Sat Apr  7 02:45:18 CEST 2012
+	- fix stat structure usage on windows, which caused bogus stat results.
+        - (libeio) make readahead emulation behave more like actual readahead by never failing.
+        - new request aio_seek.
+        - new request aio_fiemap.
+        - autogenerate the #ifdef/#define 0 blocks for symbols we export.
+
+4.12 Fri Dec 30 08:51:25 CET 2011
+	- realpath would return a random value if the name was too long,
+          instead of -1.
+        - port to c89.
+
+4.11 Mon Oct 10 00:24:11 CEST 2011
+	- libeio didn't compile on !linux (Paul Howarth).
+
+4.1  Sun Oct  9 10:24:11 CEST 2011
+        - IO::AIO did access uninitialised memory on unsuccessful stats.
+	- (libeio) added syncfs syscall wrapper.
+        - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
+        - (libeio) support multiple indepenent working directories.
+        - applied speling corrections by Nicholas Bamber.
+        - tune treescan #threads and #outstanding requests a bit.
+        - reduce the number of file descriptors in use at any one time
+          in treescan, to avoid running out of them (and using too much ram).
+        - take advantage of working directoriy abstractions
+          in aio_scandir and treescan.
+        - reduce compiled size by ~10% by not inlining some key functionality.
+        - added --progress switch to treescan.
+
+4.0   Mon Jul 18 05:01:10 CEST 2011
+	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
+          see FORK BEHAVIOUR in manpage for details.
+	- passes testsuite on win32 now and may actually work
+          (activestate 5.10.1 / MSVC6, YMMV).
+	- (libeio) fix a deadlock where a wakeup signal could be missed when
+          a timeout occured at the same time.
+	- (libeio) added realpath.
+        - (libeio) added fallocate.
+	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
+        - (libeio) do not acquire any locks when forking.
+        - (libeio) use fewer time() syscalls when waiting for new requests.
+
+3.93  Wed Jun 29 23:44:18 CEST 2011
+	- ECB.H WAS MISSING.
+
+3.92  Wed Jun 29 14:45:41 CEST 2011
+	- ecb.h was missing.
+
+3.91  Wed Jun 29 13:24:42 CEST 2011
+        - (libeio) work around a Linux (and likely FreeBSD and other
+          kernels) bug where sendfile would not transfer all the requested
+          bytes on large transfers, using a heuristic.
+        - buggy sendfile caused aio_move/copy to sometimes fail for big
+          files (fortunately it checks that the whole file has been
+          transferred...)
+        - use libecb for higher performance and higher portability.
+        - (libeio) disable sendfile on darwin, it's too broken.
+        - disable fork tests on !linux, as only linux supports mixing
+          pthread and fork in perl.
+        - document the fact that fork doesn't work anymore when using
+          this module, on anything !GNU/Linux.
+        - increase timeout in t/04_fork.t, as too many CPAN-tester setups
+          run on a 0.1MHz cpu. Or so.
+
+3.9  Fri May 27 02:43:47 CEST 2011
+        - (libeio) fix memory corruption in aio_readdirx for the flags
+          combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
+        - add lots of newer POSIX and GNU/Linux-specific open
+          flags.
+
+3.8  Sun Mar 27 12:25:33 CEST 2011
+	- use nonstandard but maybe-working-on-bsd fork technique.
+	- support a max_idle value of 0.
+	- support setting of idle timeout value (IO::AIO::idle_timeout).
+
+3.72 Fri Feb 11 04:25:38 CET 2011
+	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
+        - aio_mknod always used a dev_t value of 0.
+        - new treescan option: --grep.
+        - add more S_IF macros, and major/minor/makedev "macros".
 
 3.71 Thu Dec 30 08:18:46 CET 2010
 	- the numerical result value passed to callbacks did not stringify
