		39
		40	4.33 Mon Jan 18 12:50:10 CET 2016
		41	- add IO::AIO::pipe2 function.
		42	- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
		43	constants.
		44	- added support for O_TMPFILE and O_PATH constants.
		45	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		46	consdtants, whether they can be sensibly used or not.
		47	- use NO_INIT where applicable.
		48	- update libecb.
		49	- added stability canary support.
		50	- updated linux super magic table to 4.3.3.
		51
		52	4.32 Wed Feb 11 20:32:11 CET 2015
		53	- replace off_t by STRLEN where appropriate, should not result in
		54	user-visible changes.

		56
		57	4.31 Tue Jun 3 03:29:27 CEST 2014
		58	- work around more 5.20 bugs. backwards compatibility my ass.
		59
		60	4.3 Fri Apr 11 06:22:38 CEST 2014
		61	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		62	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		63	in 5.18. What's so attractive about giving a shit about backwards
		64	compatibility - I will never understand.
		65
		66	4.2 Sat Jan 25 01:13:14 CET 2014
		67	- aio_group could corrupt memory because it didn't restore
		68	the stack after req_submit.
		69	- be more careful on (e.g. permission) errors in bin/treescan.
		70	- work around changes in ExtUtils::MakeMaker.
		71	- (libeio) implement aio_realpath for win32.
		72	- (xthread) work around compile time bugs in ptw32.
		73	- added IO::AIO::pipesize.
		74	- (libecb) insignificant update.
		75
		76	4.19 Sun Jan 6 12:47:26 CET 2013
		77	- avoid endless loop in fiemap with some XFS files.
		78	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		79	and call rename/rmdir instead of renameat/unlinkat.
		80
		81	4.18 Thu Oct 11 07:01:26 CEST 2012
		82	- fix unintended xthread_create by intentionalising it :)
		83
		84	4.17 Thu Oct 11 05:19:47 CEST 2012
		85	- rename aio_fallocate to aio_allocate, to match documentation.
		86	- add list of linux fsid values to aio_statvfs docs.
		87	- work around a bug in btrfs' FIEMAP ioctl implementation.
		88	- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
		89	as per unix spec.
		90
		91	4.16 Tue Aug 14 05:39:03 CEST 2012
		92	- aio_statvfs was wromgly marked for wd emulation, causing
		93	it to malfunction for paths.
		94	- fix a crash in aio_fiemap, when used on ranges without any
		95	extents.
		96	- work around linux kernel bug (at least in 3.2): kernel might
		97	trash fiemap input arguments.
		98	- work around linux kernel bug (at least in 3.2): kernel does not
		99	set FIEMAP_EXTENT_LAST on last segment.
		100	- work around linux kernel bug (at least in 3.2): kernel silently
		101	truncates segment count if a file.
		102	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		103	to quick overview.
		104	- splice can corrupt data.
		105	- (libeio) remove pread/pwrite emulation.
		106	- do not grow mmaped scalars in aio_read.
		107	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		108	- provide pread/pwrite for win32, making it link again on native win32.
		109
		110	4.15 Tue Apr 10 06:59:00 CEST 2012
		111	- always include linux/types.h for fiemap, for compatibility to
		112	ancient systems (Paul Howarth).
		113	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		114	- provide SEEK_HOLE and SEEK_DATA, if available.
		115	- work around (again!) an immensely stupid bug in RHEL, defining
		116	autoconf macros in linux system headers (analysed by Paul Howarth).
		117
		118	4.14 Sat Apr 7 02:45:18 CEST 2012
		119	- fix stat structure usage on windows, which caused bogus stat results.
		120	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		121	- new request aio_seek.
		122	- new request aio_fiemap.
		123	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		124
		125	4.12 Fri Dec 30 08:51:25 CET 2011
		126	- realpath would return a random value if the name was too long,
		127	instead of -1.
		128	- port to c89.
		129
		130	4.11 Mon Oct 10 00:24:11 CEST 2011
		131	- libeio didn't compile on !linux (Paul Howarth).
		132
		133	4.1 Sun Oct 9 10:24:11 CEST 2011
		134	- IO::AIO did access uninitialised memory on unsuccessful stats.
		135	- (libeio) added syncfs syscall wrapper.
		136	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		137	- (libeio) support multiple indepenent working directories.
		138	- applied speling corrections by Nicholas Bamber.
		139	- tune treescan #threads and #outstanding requests a bit.
		140	- reduce the number of file descriptors in use at any one time
		141	in treescan, to avoid running out of them (and using too much ram).
		142	- take advantage of working directoriy abstractions
		143	in aio_scandir and treescan.
		144	- reduce compiled size by ~10% by not inlining some key functionality.
		145	- added --progress switch to treescan.
		146
		147	4.0 Mon Jul 18 05:01:10 CEST 2011
		148	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		149	see FORK BEHAVIOUR in manpage for details.
		150	- passes testsuite on win32 now and may actually work
		151	(activestate 5.10.1 / MSVC6, YMMV).
		152	- (libeio) fix a deadlock where a wakeup signal could be missed when
		153	a timeout occured at the same time.
		154	- (libeio) added realpath.
		155	- (libeio) added fallocate.
		156	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		157	- (libeio) do not acquire any locks when forking.
		158	- (libeio) use fewer time() syscalls when waiting for new requests.
		159
		160	3.93 Wed Jun 29 23:44:18 CEST 2011
		161	- ECB.H WAS MISSING.
		162
		163	3.92 Wed Jun 29 14:45:41 CEST 2011
		164	- ecb.h was missing.
		165
		166	3.91 Wed Jun 29 13:24:42 CEST 2011
		167	- (libeio) work around a Linux (and likely FreeBSD and other
		168	kernels) bug where sendfile would not transfer all the requested
		169	bytes on large transfers, using a heuristic.
		170	- buggy sendfile caused aio_move/copy to sometimes fail for big
		171	files (fortunately it checks that the whole file has been
		172	transferred...)
		173	- use libecb for higher performance and higher portability.
		174	- (libeio) disable sendfile on darwin, it's too broken.
		175	- disable fork tests on !linux, as only linux supports mixing
		176	pthread and fork in perl.
		177	- document the fact that fork doesn't work anymore when using
		178	this module, on anything !GNU/Linux.
		179	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		180	run on a 0.1MHz cpu. Or so.
		181
		182	3.9 Fri May 27 02:43:47 CEST 2011
		183	- (libeio) fix memory corruption in aio_readdirx for the flags
		184	combination READDIR_STAT_ORDER \| READDIR_DIRS_FIRST.

		186	flags.
		187
		188	3.8 Sun Mar 27 12:25:33 CEST 2011
		189	- use nonstandard but maybe-working-on-bsd fork technique.
		190	- support a max_idle value of 0.
		191	- support setting of idle timeout value (IO::AIO::idle_timeout).
		192
		193	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	194	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		195	- aio_mknod always used a dev_t value of 0.
14	- new treescan option: --grep.	196	- new treescan option: --grep.
		197	- add more S_IF macros, and major/minor/makedev "macros".
15		198
16	3.71 Thu Dec 30 08:18:46 CET 2010	199	3.71 Thu Dec 30 08:18:46 CET 2010
17	- the numerical result value passed to callbacks did not stringify	200	- the numerical result value passed to callbacks did not stringify
18	correctly, due to internal reuse and failure to reset the sv flags.	201	correctly, due to internal reuse and failure to reset the sv flags.
19	- actually test for posix_[mf]advise, as at least uClibc defines	202	- actually test for posix_[mf]advise, as at least uClibc defines
