		45
		46	4.34 Sun May 1 19:18:24 CEST 2016

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

		58	- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
		59	constants.
		60	- added support for O_TMPFILE and O_PATH constants.
		61	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		62	consdtants, whether they can be sensibly used or not.

		77	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		78	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		79	in 5.18. What's so attractive about giving a shit about backwards
		80	compatibility - I will never understand.
		81
		82	4.2 Sat Jan 25 01:13:14 CET 2014
		83	- aio_group could corrupt memory because it didn't restore

		105	as per unix spec.
		106
		107	4.16 Tue Aug 14 05:39:03 CEST 2012
		108	- aio_statvfs was wromgly marked for wd emulation, causing

		115	set FIEMAP_EXTENT_LAST on last segment.
		116	- work around linux kernel bug (at least in 3.2): kernel silently
		117	truncates segment count if a file.
		118	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		119	to quick overview.
		120	- splice can corrupt data.
		121	- (libeio) remove pread/pwrite emulation.
		122	- do not grow mmaped scalars in aio_read.
		123	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		124	- provide pread/pwrite for win32, making it link again on native win32.
		125
		126	4.15 Tue Apr 10 06:59:00 CEST 2012
		127	- always include linux/types.h for fiemap, for compatibility to
		128	ancient systems (Paul Howarth).

		130	- provide SEEK_HOLE and SEEK_DATA, if available.
		131	- work around (again!) an immensely stupid bug in RHEL, defining
		132	autoconf macros in linux system headers (analysed by Paul Howarth).
		133
		134	4.14 Sat Apr 7 02:45:18 CEST 2012
		135	- fix stat structure usage on windows, which caused bogus stat results.

		137	- new request aio_seek.
		138	- new request aio_fiemap.
		139	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		140
		141	4.12 Fri Dec 30 08:51:25 CET 2011
		142	- realpath would return a random value if the name was too long,
		143	instead of -1.
		144	- port to c89.
		145
		146	4.11 Mon Oct 10 00:24:11 CEST 2011
		147	- libeio didn't compile on !linux (Paul Howarth).
		148
		149	4.1 Sun Oct 9 10:24:11 CEST 2011
		150	- IO::AIO did access uninitialised memory on unsuccessful stats.
		151	- (libeio) added syncfs syscall wrapper.
		152	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		153	- (libeio) support multiple indepenent working directories.
		154	- applied speling corrections by Nicholas Bamber.
		155	- tune treescan #threads and #outstanding requests a bit.
		156	- reduce the number of file descriptors in use at any one time
		157	in treescan, to avoid running out of them (and using too much ram).
		158	- take advantage of working directoriy abstractions
		159	in aio_scandir and treescan.
		160	- reduce compiled size by ~10% by not inlining some key functionality.
		161	- added --progress switch to treescan.
		162
		163	4.0 Mon Jul 18 05:01:10 CEST 2011
		164	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		165	see FORK BEHAVIOUR in manpage for details.
		166	- passes testsuite on win32 now and may actually work
		167	(activestate 5.10.1 / MSVC6, YMMV).

		169	a timeout occured at the same time.
		170	- (libeio) added realpath.

		174	- (libeio) use fewer time() syscalls when waiting for new requests.
		175
		176	3.93 Wed Jun 29 23:44:18 CEST 2011
		177	- ECB.H WAS MISSING.
		178
		179	3.92 Wed Jun 29 14:45:41 CEST 2011
		180	- ecb.h was missing.
		181
		182	3.91 Wed Jun 29 13:24:42 CEST 2011
		183	- (libeio) work around a Linux (and likely FreeBSD and other
		184	kernels) bug where sendfile would not transfer all the requested
		185	bytes on large transfers, using a heuristic.
		186	- buggy sendfile caused aio_move/copy to sometimes fail for big
		187	files (fortunately it checks that the whole file has been
		188	transferred...)
		189	- use libecb for higher performance and higher portability.
		190	- (libeio) disable sendfile on darwin, it's too broken.

		193	- document the fact that fork doesn't work anymore when using
		194	this module, on anything !GNU/Linux.
		195	- increase timeout in t/04_fork.t, as too many CPAN-tester setups

		208
		209	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	210	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.

		212	- new treescan option: --grep.

16	- the numerical result value passed to callbacks did not stringify	216	- the numerical result value passed to callbacks did not stringify
17	correctly, due to internal reuse and failure to reset the sv flags.	217	correctly, due to internal reuse and failure to reset the sv flags.
