+4.73 Fri Dec  4 02:08:37 CET 2020
+	- def0.h was not uptodate, running into musl problems
+          (reported by B Fraser).
+	- IO::AIO::splice and IO::AIO::tee didn't properly return
+          64 bit values.
+	- added IO::AIO::accept4.
+	- add various F_SEAL related fcntl constants.
+        - removed experimental marker for fdlimit functions.
+        - fiemap now includes the last segment even if it overflows
+          the end offset, which is arguably the correct behaviour.
+
+4.72 Wed Apr  3 04:56:03 CEST 2019
+        - (libeio) if fd 0 is available do not use it for aio_wd, as it
+          collides with IO::AIO::CWD.
+	- added IO::AIO::memfd_create.
+	- correctly include <sys/uio.h> in the vmsplice test.
+        - reduce codesize by ~7% on amd64 by declaring more functions
+          as noinline.
+        - documentation fixes and updates.
+        - experimental and undocumented preliminary support for synchronous statx.
+
+4.71 Sun Mar 10 13:09:26 CET 2019
+	- due to an error in the linux manpages, the configure tests
+          for readahead, sync_file_range, splice etc. failed. This has been fixed.
+
+4.7  Mon Mar  4 11:28:13 CET 2019
+	- majorly speed up scandir for the very special case of a non-POSIX
+          filesystem that nevertheless reports valid dt_type information.
+          The only known filesystem of this type is currently btrfs, which
+          didn't get it's act together to implement POSIX semantics in all
+          these years, and I am tired of waiting.
+	- add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
+	- neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
+          were detected by autoconf.
+
+4.6  Sat Aug 25 21:58:36 CEST 2018
 	- add st_btime, st_btimesec, st_btimensec and st_gen accessors,
           mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
           but only st_gen on openbsd because they compiled their perl without support

         - #undef utime on win32, maybe this helps some reports of utime hangs.
         - minor doc improvements.
         - minor configure cleanups.
+        - use $Config{perllibs} instead of libs for configure. might help people
+          who didn't install all perl dependencies (might break things as well).

 	- include sys/mkdev.h or sys/sysmacros.h if available.
