+
+ - events on files were not always generated properly with the
+ epoll backend (testcase by Assaf Inbal).
+ - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
+ - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
+ - use a reasonable fallback for EV_NSIG instead of erroring out
+ when we can't detect the signal set size.
+ - in the absence of autoconf, do not use the clock syscall
+ on glibc >= 2.17 (avoids the syscall AND -lrt on systems
+ doing clock_gettime in userspace).
+ - ensure extern "C" function pointers are used for externally-visible
+ loop callbacks (not watcher callbacks yet).
+ - (ecb) work around memory barriers and volatile apparently both being
+ broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

+ - destroying a non-default loop would stop the global waitpid
+ watcher (Denis Bilenko).
+ - queueing pending watchers of higher priority from a watcher now invokes
+ them in a timely fashion (reported by Denis Bilenko).
+ - add throw() to all libev functions that cannot throw exceptions, for
+ further code size decrease when compiling for C++.
+ - add throw () to callbacks that must not throw exceptions (allocator,
+ syserr, loop acquire/release, periodic reschedule cbs).
+ - fix event_base_loop return code, add event_get_callback, event_base_new,
+ event_base_get_method calls to improve libevent 1.x emulation and add
+ some libevent 2.x functionality (based on a patch by Jeff Davey).
+ - add more memory fences to fix a bug reported by Jeff Davey. Better
+ be overfenced than underprotected.
+ - ev_run now returns a boolean status (true meaning watchers are
+ still active).
- ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
libev's EV_ERROR (reported by 191919).

-TODO: Jeff Davey libev patch
- (ecb) add memory fence support for xlC (Darin McBride).
- (ecb) add memory fence support for gcc-mips (Anton Kirilov).
+ - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
- work around some kernels losing file descriptors by leaking
the kqueue descriptor in the child.
+ - work around linux inotify not reporting IN_ATTRIB changes for directories
+ in many cases.
+ - include sys/syscall.h instead of plain syscall.h.
+ - check for io watcher loops in ev_verify, check for the most
+ common reported usage bug in ev_io_start.
+ - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
+ - always use WSASend/WSARecv directly on windows, hoping that this
+ works in all cases (unlike read/write/send/recv...).
+ - try to detect signals around a fork faster (test program by
+ Denis Bilenko).
+ - work around recent glibc versions that leak memory in realloc.
+ - rename ev::embed::set to ev::embed::set_embed to avoid clashing
+ the watcher base set (loop) method.
+ - rewrite the async/signal pipe logic to always keep a valid fd, which
+ simplifies (and hopefully correctifies :) the race checking
+ on fork, at the cost of one extra fd.
+ - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
+ inotify-supporting filesystems.
+ - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
+ versions ignore it before
+ (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
+ - add some untested android support.
+ - enum expressions must be of type int (reported by Juan Pablo L).
4.11 Sat Feb 4 19:52:39 CET 2012
- INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
- implement ev_suspend and ev_resume.
- new EV_CUSTOM revents flag for use by applications.
- add documentation section about priorities.
- - add a glossary to the dcoumentation.
+ - add a glossary to the documentation.
- extend the ev_fork description slightly.
- optimize a jump out of call_pending.
