		39
		40	4.51 Sun Aug 12 07:24:14 CEST 2018
		41	- complete rework of the autoconf framework: IO::AIO now uses its own
		42	config.h, separate from libeio, and tries to test the actual perl
		43	environment, not the standard system environment.
		44	- provide nanosecond-accracy stat time accessors for both perl and IO::AIO
		45	stat functions.
		46	- removed non-portable C++ syntax from eio.c.
		47	- try to fix readdir tests on cygwin spuriously failing.
		48
		49	4.5 Wed Aug 1 00:23:55 CEST 2018
		50	- aio_mtouch touch all pages as requested, not just the first page in most cases.
		51	- new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
		52	and MREMAP_FIXED.
		53	- add O_ACCMODE.
		54	- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.

		57	- new aio_slurp request.
		58	- add (experimental) IO::AIO::eventfd and timerfd* function.
		59	- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
		60	- point out that aio_copy overwrites existing files.
		61	- removed filesystem magic number table from aio_statvfs docs as
		62	statvfs doesn't actually return this info at all (statfs does).
		63	- add a bunch of (mostly linux-specific) constants for use in ioctls
		64	(see aio_ioctl docs).
		65	- treescan now has a proper manpage and useful --help output.
		66	- new option --sync in treescan, to sync everything in a subtree.
		67	- changed default for aio_msync flags to MSYNC_SYNC.
		68	- document offset/length behaviour of mprotect/madvise.

		75	- add IO:AIO::FALLOC_FL_UNSHARE.
		76	- update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
		77	and better eventfd detection.
		78
		79	4.34 Sun May 1 19:18:24 CEST 2016
		80	- def0.h was not properly generated during previous release, causing
		81	compile errors on various platforms.
		82	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		83	- removed duplicate definition of MAP_HUGETLB, that was found due to
		84	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		85	- added (untested!) aio_fcntl, aio_ioctl requests.
		86	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
		87	as manpages-dev originally claimed.
		88
		89	4.33 Mon Jan 18 12:50:10 CET 2016

		97	- update libecb.
		98	- added stability canary support.
		99	- updated linux super magic table to 4.3.3.
		100
		101	4.32 Wed Feb 11 20:32:11 CET 2015
		102	- replace off_t by STRLEN where appropriate, should not result in
		103	user-visible changes.
		104	- update ecb.h for C11 compatibility.
		105
		106	4.31 Tue Jun 3 03:29:27 CEST 2014
		107	- work around more 5.20 bugs. backwards compatibility my ass.
		108
		109	4.3 Fri Apr 11 06:22:38 CEST 2014
		110	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		111	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		112	in 5.18. What's so attractive about giving a shit about backwards
		113	compatibility - I will never understand.
		114
		115	4.2 Sat Jan 25 01:13:14 CET 2014
		116	- aio_group could corrupt memory because it didn't restore

		119	- work around changes in ExtUtils::MakeMaker.
		120	- (libeio) implement aio_realpath for win32.
		121	- (xthread) work around compile time bugs in ptw32.
		122	- added IO::AIO::pipesize.
		123	- (libecb) insignificant update.
		124
		125	4.19 Sun Jan 6 12:47:26 CET 2013
		126	- avoid endless loop in fiemap with some XFS files.
		127	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		128	and call rename/rmdir instead of renameat/unlinkat.
		129
		130	4.18 Thu Oct 11 07:01:26 CEST 2012
		131	- fix unintended xthread_create by intentionalising it :)
		132
		133	4.17 Thu Oct 11 05:19:47 CEST 2012
		134	- rename aio_fallocate to aio_allocate, to match documentation.
		135	- add list of linux fsid values to aio_statvfs docs.
		136	- work around a bug in btrfs' FIEMAP ioctl implementation.
		137	- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
		138	as per unix spec.
		139
		140	4.16 Tue Aug 14 05:39:03 CEST 2012
		141	- aio_statvfs was wromgly marked for wd emulation, causing
		142	it to malfunction for paths.
		143	- fix a crash in aio_fiemap, when used on ranges without any
		144	extents.
		145	- work around linux kernel bug (at least in 3.2): kernel might
		146	trash fiemap input arguments.
		147	- work around linux kernel bug (at least in 3.2): kernel does not
		148	set FIEMAP_EXTENT_LAST on last segment.
		149	- work around linux kernel bug (at least in 3.2): kernel silently
		150	truncates segment count if a file.
		151	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		152	to quick overview.
		153	- splice can corrupt data.
		154	- (libeio) remove pread/pwrite emulation.
		155	- do not grow mmaped scalars in aio_read.
		156	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		157	- provide pread/pwrite for win32, making it link again on native win32.
		158
		159	4.15 Tue Apr 10 06:59:00 CEST 2012
		160	- always include linux/types.h for fiemap, for compatibility to
		161	ancient systems (Paul Howarth).
		162	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		163	- provide SEEK_HOLE and SEEK_DATA, if available.
		164	- work around (again!) an immensely stupid bug in RHEL, defining
		165	autoconf macros in linux system headers (analysed by Paul Howarth).
		166
		167	4.14 Sat Apr 7 02:45:18 CEST 2012
		168	- fix stat structure usage on windows, which caused bogus stat results.

		170	- new request aio_seek.
		171	- new request aio_fiemap.

		173
		174	4.12 Fri Dec 30 08:51:25 CET 2011
		175	- realpath would return a random value if the name was too long,
		176	instead of -1.
		177	- port to c89.
		178
		179	4.11 Mon Oct 10 00:24:11 CEST 2011
		180	- libeio didn't compile on !linux (Paul Howarth).
		181
		182	4.1 Sun Oct 9 10:24:11 CEST 2011
		183	- IO::AIO did access uninitialised memory on unsuccessful stats.
		184	- (libeio) added syncfs syscall wrapper.
		185	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		186	- (libeio) support multiple indepenent working directories.
		187	- applied speling corrections by Nicholas Bamber.
		188	- tune treescan #threads and #outstanding requests a bit.
		189	- reduce the number of file descriptors in use at any one time
		190	in treescan, to avoid running out of them (and using too much ram).
		191	- take advantage of working directoriy abstractions
		192	in aio_scandir and treescan.
		193	- reduce compiled size by ~10% by not inlining some key functionality.
		194	- added --progress switch to treescan.
		195
		196	4.0 Mon Jul 18 05:01:10 CEST 2011
		197	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		198	see FORK BEHAVIOUR in manpage for details.
		199	- passes testsuite on win32 now and may actually work
		200	(activestate 5.10.1 / MSVC6, YMMV).
		201	- (libeio) fix a deadlock where a wakeup signal could be missed when
		202	a timeout occured at the same time.
		203	- (libeio) added realpath.
		204	- (libeio) added fallocate.
		205	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		206	- (libeio) do not acquire any locks when forking.
		207	- (libeio) use fewer time() syscalls when waiting for new requests.
		208
		209	3.93 Wed Jun 29 23:44:18 CEST 2011
		210	- ECB.H WAS MISSING.
		211
		212	3.92 Wed Jun 29 14:45:41 CEST 2011
		213	- ecb.h was missing.
		214
		215	3.91 Wed Jun 29 13:24:42 CEST 2011
		216	- (libeio) work around a Linux (and likely FreeBSD and other
		217	kernels) bug where sendfile would not transfer all the requested
		218	bytes on large transfers, using a heuristic.
		219	- buggy sendfile caused aio_move/copy to sometimes fail for big
		220	files (fortunately it checks that the whole file has been
		221	transferred...)
		222	- use libecb for higher performance and higher portability.
		223	- (libeio) disable sendfile on darwin, it's too broken.
		224	- disable fork tests on !linux, as only linux supports mixing
		225	pthread and fork in perl.
		226	- document the fact that fork doesn't work anymore when using
		227	this module, on anything !GNU/Linux.
		228	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		229	run on a 0.1MHz cpu. Or so.
		230
		231	3.9 Fri May 27 02:43:47 CEST 2011
		232	- (libeio) fix memory corruption in aio_readdirx for the flags
		233	combination READDIR_STAT_ORDER \| READDIR_DIRS_FIRST.
		234	- add lots of newer POSIX and GNU/Linux-specific open
		235	flags.
		236
		237	3.8 Sun Mar 27 12:25:33 CEST 2011
		238	- use nonstandard but maybe-working-on-bsd fork technique.
		239	- support a max_idle value of 0.
		240	- support setting of idle timeout value (IO::AIO::idle_timeout).
		241
		242	3.72 Fri Feb 11 04:25:38 CET 2011
		243	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		244	- aio_mknod always used a dev_t value of 0.
		245	- new treescan option: --grep.
		246	- add more S_IF macros, and major/minor/makedev "macros".
		247
		248	3.71 Thu Dec 30 08:18:46 CET 2010
		249	- the numerical result value passed to callbacks did not stringify
		250	correctly, due to internal reuse and failure to reset the sv flags.
		251	- actually test for posix_[mf]advise, as at least uClibc defines
		252	_POSIX_ADVISORY_INFO without actually having any of the required
		253	funcitonality. ugh.
		254
		255	3.7 Mon Nov 1 23:00:34 CET 2010
		256	- implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
		257	aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
		258	- document the sad state of affairs w.r.t. pthread on many bsds.
		259	- do not enable mmap on systems without _POSIX_MAPPED_FILES
		260	(openbsd 4.8).
		261	- do not leak memory in IO::AIO::mmap when the scalar already
		262	had string-data.
		263	- add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
		264	them.
		265	- cache the result IV, for a minor speedup in the common case.
		266	- croak when an mmapped-scalar changes location, to detect
		267	user-errors better.
		268	- fix aio_readlink prototype.
		269
		270	3.65 Wed Mar 31 02:45:05 CEST 2010
		271	- actually use PATH_MAX instead of NAME_MAX for readlink, as to not
		272	cut off long pathnames in aio_readlink (based on patch by
		273	Rasmus Andersson).
		274	- a double fork partially killed the event pipe (great testcase
		275	by dormando). affects IO::AIO, BDB and Async::Interrupt.
		276	- suck steve's dick and rename our symbols to avoid colliding
		277	with nonstandard identifier spam on the broken os x pseudo-os.
		278	affects IO::AIO and BDB.
		279
		280	3.6 Mon Jan 11 00:43:39 CET 2010
