37		48
		49	4.73 Fri Dec 4 02:08:37 CET 2020
		50	- def0.h was not uptodate, running into musl problems
		51	(reported by B Fraser).
		52	- IO::AIO::splice and IO::AIO::tee didn't properly return
		53	64 bit values.
		54	- added IO::AIO::accept4.
		55	- add various F_SEAL related fcntl constants.
		56	- removed experimental marker for fdlimit functions.
		57	- fiemap now includes the last segment even if it overflows
		58	the end offset, which is arguably the correct behaviour.
		59
		60	4.72 Wed Apr 3 04:56:03 CEST 2019
		61	- (libeio) if fd 0 is available do not use it for aio_wd, as it
		62	collides with IO::AIO::CWD.
		63	- added IO::AIO::memfd_create.
		64	- correctly include <sys/uio.h> in the vmsplice test.
		65	- reduce codesize by ~7% on amd64 by declaring more functions
		66	as noinline.
		67	- documentation fixes and updates.
		68	- experimental and undocumented preliminary support for synchronous statx.
		69
		70	4.71 Sun Mar 10 13:09:26 CET 2019
		71	- due to an error in the linux manpages, the configure tests
		72	for readahead, sync_file_range, splice etc. failed. This has been fixed.
		73
		74	4.7 Mon Mar 4 11:28:13 CET 2019
		75	- majorly speed up scandir for the very special case of a non-POSIX
		76	filesystem that nevertheless reports valid dt_type information.
		77	The only known filesystem of this type is currently btrfs, which
		78	didn't get it's act together to implement POSIX semantics in all
		79	these years, and I am tired of waiting.
		80	- add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall.
		81	- neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
		82	were detected by autoconf.
		83
		84	4.6 Sat Aug 25 21:58:36 CEST 2018
		85	- add st_btime, st_btimesec, st_btimensec and st_gen accessors,
		86	mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
		87	but only st_gen on openbsd because they compiled their perl without support
		88	for birthtimes).
		89	- fix madvise and munlock to properly support negative offsets.
		90	- allocate fd for the aio_close at boot time, to guarantee it working
		91	later, rather than calling abort when it fails. also avoids
		92	close-on-exec race issues after module load.
		93	- #undef utime on win32, maybe this helps some reports of utime hangs.
		94	- minor doc improvements.
		95	- minor configure cleanups.
		96	- use $Config{perllibs} instead of libs for configure. might help people
		97	who didn't install all perl dependencies (might break things as well).
		98
		99	4.54 Tue Aug 14 13:54:48 CEST 2018
		100	- include sys/mkdev.h or sys/sysmacros.h if available.
		101	- further tweaks to configure invocation for systems requiring --rpath.
		102	- no longer rely on custom paths on win32 platforms.
		103	- try to work around buggy PAGESIZE macro on solaris.
		104
		105	4.53 Tue Aug 14 11:27:50 CEST 2018
		106	- add $Config{libs} to LIBS for configure, to work around systems
		107	with broken library dependencies (... openbsd).
		108
		109	4.52 Sun Aug 12 08:09:45 CEST 2018
		110	- config.h.in was missing in distribution.
		111
		112	4.51 Sun Aug 12 07:24:14 CEST 2018
		113	- complete rework of the autoconf framework: IO::AIO now uses its own
		114	config.h, separate from libeio, and tries to test the actual perl
		115	environment, not the standard system environment.
		116	- provide nanosecond-accracy stat time accessors for both perl and IO::AIO
		117	stat functions.
		118	- removed non-portable C++ syntax from eio.c.
		119	- try to fix readdir tests on cygwin spuriously failing.
		120
		121	4.5 Wed Aug 1 00:23:55 CEST 2018
		122	- aio_mtouch touch all pages as requested, not just the first page in most cases.
		123	- new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
		124	and MREMAP_FIXED.
		125	- add O_ACCMODE.
		126	- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
		127
		128	4.4 Tue Feb 20 07:54:12 CET 2018
		129	- new aio_slurp request.
		130	- add (experimental) IO::AIO::eventfd and timerfd* function.
		131	- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
		132	- point out that aio_copy overwrites existing files.
		133	- removed filesystem magic number table from aio_statvfs docs as
		134	statvfs doesn't actually return this info at all (statfs does).
		135	- add a bunch of (mostly linux-specific) constants for use in ioctls
		136	(see aio_ioctl docs).
		137	- treescan now has a proper manpage and useful --help output.
		138	- new option --sync in treescan, to sync everything in a subtree.
		139	- changed default for aio_msync flags to MSYNC_SYNC.
		140	- document offset/length behaviour of mprotect/madvise.
		141	- support linux's renameat2 (via aio_rename2).
		142	- add aio_rename2, an aio_rename with flags.
		143	- add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
		144	- add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
		145	- (libeio) use posix_close if available.
		146	- (libeio) internal close() calls no longer disturb errno.
		147	- add IO:AIO::FALLOC_FL_UNSHARE.
		148	- update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
		149	and better eventfd detection.
		150
		151	4.34 Sun May 1 19:18:24 CEST 2016
		152	- def0.h was not properly generated during previous release, causing
		153	compile errors on various platforms.
		154	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		155	- removed duplicate definition of MAP_HUGETLB, that was found due to
		156	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		157	- added (untested!) aio_fcntl, aio_ioctl requests.
		158	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
		159	as manpages-dev originally claimed.
		160
