+	- 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.

+	- 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
+          for birthtimes).
+        - fix madvise and munlock to properly support negative offsets.
+        - allocate fd for the aio_close at boot time, to guarantee it working
+          later, rather than calling abort when it fails. also avoids
+          close-on-exec race issues after module load.
+        - #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).
+
+4.54 Tue Aug 14 13:54:48 CEST 2018
+	- include sys/mkdev.h or sys/sysmacros.h if available.
+        - further tweaks to configure invocation for systems requiring --rpath.
+        - no longer rely on custom paths on win32 platforms.
+        - try to work around buggy PAGESIZE macro on solaris.
+
+4.53 Tue Aug 14 11:27:50 CEST 2018
+	- add $Config{libs} to LIBS for configure, to work around systems
+          with broken library dependencies (... openbsd).

+	- config.h.in was missing in distribution.
+
+4.51 Sun Aug 12 07:24:14 CEST 2018
+	- complete rework of the autoconf framework: IO::AIO now uses its own
+          config.h, separate from libeio, and tries to test the actual perl
+          environment, not the standard system environment.
+        - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
+          stat functions.
+	- removed non-portable C++ syntax from eio.c.
+        - try to fix readdir tests on cygwin spuriously failing.

+4.5  Wed Aug  1 00:23:55 CEST 2018
+	- aio_mtouch touch all pages as requested, not just the first page in most cases.
+        - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
+          and MREMAP_FIXED.
+        - add O_ACCMODE.
+	- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.

+        - point out that aio_copy overwrites existing files.
         - removed filesystem magic number table from aio_statvfs docs as
           statvfs doesn't actually return this info at all (statfs does).
         - add a bunch of (mostly linux-specific) constants for use in ioctls
