		52	- config.h.in was missing in distribution.
		53
		54	4.51 Sun Aug 12 07:24:14 CEST 2018
		55	- complete rework of the autoconf framework: IO::AIO now uses its own
		56	config.h, separate from libeio, and tries to test the actual perl
		57	environment, not the standard system environment.
		58	- provide nanosecond-accracy stat time accessors for both perl and IO::AIO
		59	stat functions.
		60	- removed non-portable C++ syntax from eio.c.
		61	- try to fix readdir tests on cygwin spuriously failing.
		62
		63	4.5 Wed Aug 1 00:23:55 CEST 2018
		64	- aio_mtouch touch all pages as requested, not just the first page in most cases.

		66	and MREMAP_FIXED.
		67	- add O_ACCMODE.
		68	- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.

		70	4.4 Tue Feb 20 07:54:12 CET 2018
		71	- new aio_slurp request.
		72	- add (experimental) IO::AIO::eventfd and timerfd* function.
		73	- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
		74	- point out that aio_copy overwrites existing files.
		75	- removed filesystem magic number table from aio_statvfs docs as
		76	statvfs doesn't actually return this info at all (statfs does).
		77	- add a bunch of (mostly linux-specific) constants for use in ioctls
		78	(see aio_ioctl docs).
		79	- treescan now has a proper manpage and useful --help output.
		80	- new option --sync in treescan, to sync everything in a subtree.
		81	- changed default for aio_msync flags to MSYNC_SYNC.
		82	- document offset/length behaviour of mprotect/madvise.

		89	- add IO:AIO::FALLOC_FL_UNSHARE.
		90	- update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
		91	and better eventfd detection.
		92
		93	4.34 Sun May 1 19:18:24 CEST 2016
		94	- def0.h was not properly generated during previous release, causing
		95	compile errors on various platforms.
		96	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		97	- removed duplicate definition of MAP_HUGETLB, that was found due to
		98	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		99	- added (untested!) aio_fcntl, aio_ioctl requests.
		100	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
		101	as manpages-dev originally claimed.
		102
		103	4.33 Mon Jan 18 12:50:10 CET 2016

		108	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		109	consdtants, whether they can be sensibly used or not.
		110	- use NO_INIT where applicable.
		111	- update libecb.
		112	- added stability canary support.

		114
		115	4.32 Wed Feb 11 20:32:11 CET 2015
		116	- replace off_t by STRLEN where appropriate, should not result in
		117	user-visible changes.
		118	- update ecb.h for C11 compatibility.
		119
		120	4.31 Tue Jun 3 03:29:27 CEST 2014
		121	- work around more 5.20 bugs. backwards compatibility my ass.
		122
		123	4.3 Fri Apr 11 06:22:38 CEST 2014
		124	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		125	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		126	in 5.18. What's so attractive about giving a shit about backwards
		127	compatibility - I will never understand.
		128
		129	4.2 Sat Jan 25 01:13:14 CET 2014
		130	- aio_group could corrupt memory because it didn't restore

		134	- (libeio) implement aio_realpath for win32.
		135	- (xthread) work around compile time bugs in ptw32.
		136	- added IO::AIO::pipesize.
		137	- (libecb) insignificant update.
		138
		139	4.19 Sun Jan 6 12:47:26 CET 2013
		140	- avoid endless loop in fiemap with some XFS files.
		141	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		142	and call rename/rmdir instead of renameat/unlinkat.
		143
		144	4.18 Thu Oct 11 07:01:26 CEST 2012
		145	- fix unintended xthread_create by intentionalising it :)
		146
		147	4.17 Thu Oct 11 05:19:47 CEST 2012
		148	- rename aio_fallocate to aio_allocate, to match documentation.
		149	- add list of linux fsid values to aio_statvfs docs.
		150	- work around a bug in btrfs' FIEMAP ioctl implementation.
		151	- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
		152	as per unix spec.
		153
		154	4.16 Tue Aug 14 05:39:03 CEST 2012
		155	- aio_statvfs was wromgly marked for wd emulation, causing

		157	- fix a crash in aio_fiemap, when used on ranges without any
		158	extents.
		159	- work around linux kernel bug (at least in 3.2): kernel might
		160	trash fiemap input arguments.
		161	- work around linux kernel bug (at least in 3.2): kernel does not
		162	set FIEMAP_EXTENT_LAST on last segment.
		163	- work around linux kernel bug (at least in 3.2): kernel silently
		164	truncates segment count if a file.
		165	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		166	to quick overview.
		167	- splice can corrupt data.
		168	- (libeio) remove pread/pwrite emulation.
		169	- do not grow mmaped scalars in aio_read.
		170	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		171	- provide pread/pwrite for win32, making it link again on native win32.
		172
		173	4.15 Tue Apr 10 06:59:00 CEST 2012
		174	- always include linux/types.h for fiemap, for compatibility to
		175	ancient systems (Paul Howarth).
		176	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		177	- provide SEEK_HOLE and SEEK_DATA, if available.
		178	- work around (again!) an immensely stupid bug in RHEL, defining
		179	autoconf macros in linux system headers (analysed by Paul Howarth).
		180
		181	4.14 Sat Apr 7 02:45:18 CEST 2012
		182	- fix stat structure usage on windows, which caused bogus stat results.
		183	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		184	- new request aio_seek.
		185	- new request aio_fiemap.

		187
		188	4.12 Fri Dec 30 08:51:25 CET 2011
		189	- realpath would return a random value if the name was too long,
		190	instead of -1.
		191	- port to c89.
		192
		193	4.11 Mon Oct 10 00:24:11 CEST 2011
		194	- libeio didn't compile on !linux (Paul Howarth).
		195
		196	4.1 Sun Oct 9 10:24:11 CEST 2011
		197	- IO::AIO did access uninitialised memory on unsuccessful stats.
		198	- (libeio) added syncfs syscall wrapper.
		199	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		200	- (libeio) support multiple indepenent working directories.
		201	- applied speling corrections by Nicholas Bamber.
		202	- tune treescan #threads and #outstanding requests a bit.
		203	- reduce the number of file descriptors in use at any one time
		204	in treescan, to avoid running out of them (and using too much ram).
		205	- take advantage of working directoriy abstractions
		206	in aio_scandir and treescan.
		207	- reduce compiled size by ~10% by not inlining some key functionality.
		208	- added --progress switch to treescan.
		209
		210	4.0 Mon Jul 18 05:01:10 CEST 2011
		211	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		212	see FORK BEHAVIOUR in manpage for details.
		213	- passes testsuite on win32 now and may actually work
		214	(activestate 5.10.1 / MSVC6, YMMV).
		215	- (libeio) fix a deadlock where a wakeup signal could be missed when
		216	a timeout occured at the same time.
		217	- (libeio) added realpath.
		218	- (libeio) added fallocate.
		219	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		220	- (libeio) do not acquire any locks when forking.
		221	- (libeio) use fewer time() syscalls when waiting for new requests.
		222
		223	3.93 Wed Jun 29 23:44:18 CEST 2011
		224	- ECB.H WAS MISSING.
		225
		226	3.92 Wed Jun 29 14:45:41 CEST 2011
		227	- ecb.h was missing.
		228
		229	3.91 Wed Jun 29 13:24:42 CEST 2011
		230	- (libeio) work around a Linux (and likely FreeBSD and other
		231	kernels) bug where sendfile would not transfer all the requested
		232	bytes on large transfers, using a heuristic.
		233	- buggy sendfile caused aio_move/copy to sometimes fail for big
		234	files (fortunately it checks that the whole file has been
		235	transferred...)
		236	- use libecb for higher performance and higher portability.
		237	- (libeio) disable sendfile on darwin, it's too broken.
		238	- disable fork tests on !linux, as only linux supports mixing
		239	pthread and fork in perl.
		240	- document the fact that fork doesn't work anymore when using
		241	this module, on anything !GNU/Linux.
		242	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		243	run on a 0.1MHz cpu. Or so.
		244
		245	3.9 Fri May 27 02:43:47 CEST 2011

		249	flags.
