51 - removed filesystem magic number table from aio_statvfs docs as
52 statvfs doesn't actually return this info at all (statfs does).

67 and better eventfd detection.
68
694.34 Sun May 1 19:18:24 CEST 2016
70 - def0.h was not properly generated during previous release, causing
71 compile errors on various platforms.
72 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
73 - removed duplicate definition of MAP_HUGETLB, that was found due to
74 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
75 - added (untested!) aio_fcntl, aio_ioctl requests.
76 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,

81 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
82 constants.
83 - added support for O_TMPFILE and O_PATH constants.

90

98
994.3 Fri Apr 11 06:22:38 CEST 2014
100 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
101 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
102 in 5.18. What's so attractive about giving a shit about backwards
103 compatibility - I will never understand.
104
1054.2 Sat Jan 25 01:13:14 CET 2014
106 - aio_group could corrupt memory because it didn't restore
107 the stack after req_submit.

124 - rename aio_fallocate to aio_allocate, to match documentation.
125 - add list of linux fsid values to aio_statvfs docs.
126 - work around a bug in btrfs' FIEMAP ioctl implementation.
127 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
128 as per unix spec.
129
1304.16 Tue Aug 14 05:39:03 CEST 2012
131 - aio_statvfs was wromgly marked for wd emulation, causing
132 it to malfunction for paths.
133 - fix a crash in aio_fiemap, when used on ranges without any
134 extents.
135 - work around linux kernel bug (at least in 3.2): kernel might
136 trash fiemap input arguments.
137 - work around linux kernel bug (at least in 3.2): kernel does not
138 set FIEMAP_EXTENT_LAST on last segment.
139 - work around linux kernel bug (at least in 3.2): kernel silently
140 truncates segment count if a file.

142 to quick overview.

150 - always include linux/types.h for fiemap, for compatibility to
151 ancient systems (Paul Howarth).
152 - experimental support for IO::AIO::splice and ::tee (no aio_...).
153 - provide SEEK_HOLE and SEEK_DATA, if available.
154 - work around (again!) an immensely stupid bug in RHEL, defining
155 autoconf macros in linux system headers (analysed by Paul Howarth).
156
1574.14 Sat Apr 7 02:45:18 CEST 2012

177 - applied speling corrections by Nicholas Bamber.
178 - tune treescan #threads and #outstanding requests a bit.
179 - reduce the number of file descriptors in use at any one time

181 - take advantage of working directoriy abstractions
182 in aio_scandir and treescan.
183 - reduce compiled size by ~10% by not inlining some key functionality.
