I am pleased to announce libev 4.33!
Distribution: http://dist.schmorp.de/libev/libev-4.33.tar.gz
Documentation:

Changes: http://cvs.schmorp.de/libev/Changes?pathrev=rel-4_33
This release is mainly a bugfix/documentation/quality improvement release.
The "major" new feature is ev_io_modify, which can modify the event watch
mask in I/O watchers without incurring overhead caused by normally having
to check whether the fd changed (as ev_io_modify doesn't change the fd),
which can be substantial with some backends (i.e. epoll).
The complete Changes since 4.31 are:
4.33 Wed Mar 18 13:22:29 CET 2020
- the 4.31 timerfd code wrongly changed the priority of the signal
fd watcher, which is usually harmless unless signal fds are
also used (found via cpan tester service).
- the documentation wrongly claimed that user may modify fd and events
members in io watchers when the watcher was stopped
(found by b_jonas).
- new ev_io_modify mutator which changes only the events member,
which can be faster. also added ev::io::set (int events) method
to ev++.h.
- officially allow a zero events mask for io watchers. this should
work with older libev versions as well but was not officially
allowed before.
- do not wake up every minute when timerfd is used to detect timejumps.
- do not wake up every minute when periodics are disabled and we have
a monotonic clock.
- support a lot more "uncommon" compile time configurations,
such as ev_embed enabled but ev_timer disabled.
- use a start/stop wrapper class to reduce code duplication in
ev++.h and make it needlessly more c++-y.
- the linux aio backend is no longer compiled in by default.
- update to libecb version 0x00010008.
