		51
		52	4.34 Sun May 1 19:18:24 CEST 2016

		54	compile errors on various platforms.
		55	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		56	- removed duplicate definition of MAP_HUGETLB, that was found due to
		57	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		58	- added (untested!) aio_fcntl, aio_ioctl requests.
		59	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,

		64	- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
		65	constants.
		66	- added support for O_TMPFILE and O_PATH constants.
		67	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		68	consdtants, whether they can be sensibly used or not.

		83	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		84	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		85	in 5.18. What's so attractive about giving a shit about backwards
		86	compatibility - I will never understand.
		87
		88	4.2 Sat Jan 25 01:13:14 CET 2014
		89	- aio_group could corrupt memory because it didn't restore

		111	as per unix spec.
		112
		113	4.16 Tue Aug 14 05:39:03 CEST 2012
		114	- aio_statvfs was wromgly marked for wd emulation, causing

		116	- fix a crash in aio_fiemap, when used on ranges without any
		117	extents.
		118	- work around linux kernel bug (at least in 3.2): kernel might
		119	trash fiemap input arguments.
		120	- work around linux kernel bug (at least in 3.2): kernel does not
		121	set FIEMAP_EXTENT_LAST on last segment.
		122	- work around linux kernel bug (at least in 3.2): kernel silently
		123	truncates segment count if a file.
		124	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		125	to quick overview.
		126	- splice can corrupt data.
		127	- (libeio) remove pread/pwrite emulation.
		128	- do not grow mmaped scalars in aio_read.
		129	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		130	- provide pread/pwrite for win32, making it link again on native win32.
		131
		132	4.15 Tue Apr 10 06:59:00 CEST 2012
		133	- always include linux/types.h for fiemap, for compatibility to
		134	ancient systems (Paul Howarth).
		135	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		136	- provide SEEK_HOLE and SEEK_DATA, if available.
		137	- work around (again!) an immensely stupid bug in RHEL, defining
		138	autoconf macros in linux system headers (analysed by Paul Howarth).
		139
		140	4.14 Sat Apr 7 02:45:18 CEST 2012
		141	- fix stat structure usage on windows, which caused bogus stat results.
		142	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		143	- new request aio_seek.
		144	- new request aio_fiemap.
		145	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		146
		147	4.12 Fri Dec 30 08:51:25 CET 2011
		148	- realpath would return a random value if the name was too long,
		149	instead of -1.
		150	- port to c89.
		151
		152	4.11 Mon Oct 10 00:24:11 CEST 2011
		153	- libeio didn't compile on !linux (Paul Howarth).
		154
		155	4.1 Sun Oct 9 10:24:11 CEST 2011
		156	- IO::AIO did access uninitialised memory on unsuccessful stats.
		157	- (libeio) added syncfs syscall wrapper.
		158	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		159	- (libeio) support multiple indepenent working directories.
		160	- applied speling corrections by Nicholas Bamber.
		161	- tune treescan #threads and #outstanding requests a bit.
		162	- reduce the number of file descriptors in use at any one time
		163	in treescan, to avoid running out of them (and using too much ram).
		164	- take advantage of working directoriy abstractions
		165	in aio_scandir and treescan.
		166	- reduce compiled size by ~10% by not inlining some key functionality.
		167	- added --progress switch to treescan.
		168
		169	4.0 Mon Jul 18 05:01:10 CEST 2011
		170	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		171	see FORK BEHAVIOUR in manpage for details.
		172	- passes testsuite on win32 now and may actually work
		173	(activestate 5.10.1 / MSVC6, YMMV).

		175	a timeout occured at the same time.
		176	- (libeio) added realpath.

		178	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		179	- (libeio) do not acquire any locks when forking.
		180	- (libeio) use fewer time() syscalls when waiting for new requests.
		181
		182	3.93 Wed Jun 29 23:44:18 CEST 2011
		183	- ECB.H WAS MISSING.
		184
		185	3.92 Wed Jun 29 14:45:41 CEST 2011
		186	- ecb.h was missing.
		187
		188	3.91 Wed Jun 29 13:24:42 CEST 2011
		189	- (libeio) work around a Linux (and likely FreeBSD and other
		190	kernels) bug where sendfile would not transfer all the requested
		191	bytes on large transfers, using a heuristic.
		192	- buggy sendfile caused aio_move/copy to sometimes fail for big
		193	files (fortunately it checks that the whole file has been
		194	transferred...)
		195	- use libecb for higher performance and higher portability.
		196	- (libeio) disable sendfile on darwin, it's too broken.

		199	- document the fact that fork doesn't work anymore when using
		200	this module, on anything !GNU/Linux.
		201	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		202	run on a 0.1MHz cpu. Or so.
		203
		204	3.9 Fri May 27 02:43:47 CEST 2011

		208	flags.
		209

		214
		215	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	216	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		217	- aio_mknod always used a dev_t value of 0.
		218	- new treescan option: --grep.
		219	- add more S_IF macros, and major/minor/makedev "macros".

15	3.71 Thu Dec 30 08:18:46 CET 2010	221	3.71 Thu Dec 30 08:18:46 CET 2010
16	- the numerical result value passed to callbacks did not stringify	222	- the numerical result value passed to callbacks did not stringify
17	correctly, due to internal reuse and failure to reset the sv flags.	223	correctly, due to internal reuse and failure to reset the sv flags.
