-TODO: rewrite scandir etc. to take avdantage of IO::AIO::WD
+        - fix a crash in aio_fiemap, when used on files without any
+          extents.
+        - work around linux kernel bug (at least in 3.2): kernel might
+          trash fiemap input arguments.
+        - work around linux kernel bug (at least in 3.2): kernel does not
+          set FIEMAP_EXTENT_LAST on last segment.
+	- 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),
