+	- new aio_slurp request.
+        - 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
+          (see aio_ioctl docs).
+        - treescan now has a proper manpage and useful --help output.
+        - new option --sync in treescan, to sync everything in a subtree.
+        - changed default for aio_msync flags to MSYNC_SYNC.
+        - document offset/length behaviour of mprotect/madvise.
+        - support linux's renameat2 (via aio_rename2).
+        - add aio_rename2, an aio_rename with flags.
+        - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
+        - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
+	- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
+        - point out that aio_copy overwrites existing files.
+        - (libeio) use posix_close if available.
+        - (libeio) internal close() calls no longer disturb errno.
+        - add IO:AIO::FALLOC_FL_UNSHARE.
+        - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES.
+
+4.34  Sun May  1 19:18:24 CEST 2016
+	- def0.h was not properly generated during previous release, causing
+          compile errors on various platforms.
+	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
+	- removed duplicate definition of MAP_HUGETLB, that was found due to
+          a bug in Perl::Tidy (testcase by alaska332@gmail.com).
+        - added (untested!) aio_fcntl, aio_ioctl requests.
+        - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
+          as manpages-dev originally claimed.
+
+4.33  Mon Jan 18 12:50:10 CET 2016
+	- add IO::AIO::pipe2 function.
+        - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
+          constants.
+        - added support for O_TMPFILE and O_PATH constants.
+        - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
+          consdtants, whether they can be sensibly used or not.
+	- use NO_INIT where applicable.
+        - update libecb.
+        - added stability canary support.
+        - updated linux super magic table to 4.3.3.
+
+4.32  Wed Feb 11 20:32:11 CET 2015
+	- replace off_t by STRLEN where appropriate, should not result in
+          user-visible changes.
+        - update ecb.h for C11 compatibility.
+
+4.31  Tue Jun  3 03:29:27 CEST 2014
+	- work around more 5.20 bugs. backwards compatibility my ass.
+
+4.3   Fri Apr 11 06:22:38 CEST 2014
+	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
+          without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
+          in 5.18. What's so attractive about giving a shit about backwards
+          compatibility - I will never understand.
+
+4.2   Sat Jan 25 01:13:14 CET 2014
 	- aio_group could corrupt memory because it didn't restore
           the stack after req_submit.
+        - be more careful on (e.g. permission) errors in bin/treescan.
 	- work around changes in ExtUtils::MakeMaker.
 	- (libeio) implement aio_realpath for win32.
         - (xthread) work around compile time bugs in ptw32.
