Changes in version 2.1.12-stable (05 Jul 2020)
This release contains mostly bug fixes (I decided not to port some features
that can be ported even without ABI breakage, if you cannot find feature that
you are interested in, please give us a note!)
Since 2.1.12 libevent will use github actions as main CI, since
it recommends itself better then travis/appveyor (and had been removed from
upstream).
Look carefully at "slightly touches the behaviour" section.
Below you will find some of changes (this list has been cleaned up from the
patches that touches only tests and similar):

Changes in version 2.1.11-stable (01 Aug 2019)
This release contains one ABI breakage fix (that had been introduced in
2.1.10, and strictly speaking this release breaks ABI again to make it
compatible with 2.1.9 and less, please take a look at 18104973 for more
details). Apart from that it contains some bug fixes, that grouped below.
And even though the return value for evbuffer_setcb() had been changed it
should ABI compatible (anyway that function is in -compat.h header).
There is also one patch that introduce new functionality, this is 546a366c,
to tune SO_RCVBUF/SO_SNDBUF in evdns, but one can count it as a bug-fix on
the application level, since before you cannot tune this settings and hence
you could stumble on problems.

Changes in version 2.1.10-stable (26 May 2019)
This release contains mostly fixes (some evbuffer oddity, AF_UNIX handling in
http server, some UB fixes and others) but also some new functionality
(without ABI breakage as usual) and now dist archive can be used for building
on windows (getopt had been added into it).
Above you will find changelog for this particular release (but with some
trivial fixes pruned out from it - to make it a little bit more informative).

Changes in version 2.1.9-beta (10 February 2019)
This changelog will differs from other releases in the next few clauses:
- contains only highlighted changes (so now it will not contains a lot of
patches that fixes some stuff in regression tests, typos, leaks fixes in
samples and so forth)
- no authors (since merge commits breaks them anyway, but AUTHORS sections in
README will be kept up to date)
- group name trimmed from commit subjects trimmed
- it's been 2 years since the previoius release, so it is pretty huge
And I think that this is more useful, so from now on it will always has the
same look (until there will too many objections of course).

Changes in version 2.1.3-alpha (1 May 2013)
Libevent 2.1.3-alpha fixes various bugs, adds new unit tests, and cleans
up the code in a couple of places. It has a new callback in evhttp for
reporting errors during a request, a new feature for allowing evdns to
not keep the event_base looping when there are no requests inflight, and
example code for writing an https client.
Libevent 2.1.3-alpha also has an important new (experimental) event
finalization feature to allow safe event teardown in multithreaded
programs. This ought to fix the longstanding bug with deadlocks in
multithreaded use of SSL-based bufferevents that some people have been
experiencing since Libevent 2.0.
Core (event finalization)
o Implement event_finalize() and related functions to avoid certain
deadlocks (8eedeab)
o Use finalization feature so bufferevents can avoid deadlocks (02fbf68)
o Always run pending finalizers when event_base_free() is called (e9ebef8)
o Remove bufferevent_del_generic_timeout_cbs as now unused (4ea4c6a)
o More documentation for finalization feature (a800b91)

Changes in version 2.1.2-alpha (18 Nov 2012)
Libevent 2.1.2-alpha includes more portable for monotonic timers,
refactors much of Libevent's internal and external infrastructure,
closes some longstanding gaps in the interface, makde other
improvements. Ths log below tries to organize features by rough area of
effect. It omits a few commits which were pure bugfixes on other commits
listed below. For more detail, see the git changelogs. For more
insight, see the "whatsnew-2.1.txt" document included in the Libevent
2.1.2-alpha distribution.
Libevent 2.1.2-alpha also includes all changes made in 2.0.19-stable
through 2.0.21-stable inclusive.
Performance (core):
o Replace pipe-based notification with EVFILT_USER where possible. This
should make multithreaded programs on OSX and *BSD alert the main thread a
little faster. (53a07fe)
o Make th_base_lock nonrecursive. (9cd5acb)
New/Changed API Functions:
o New event_get_priority() function to return an event's priority (f90e255)
o Add a bufferevent_get_priority() function (bd39554)
o Add an event_base_loopcontinue() to tell Libevent to rescan for more
events right away (7d6aa5e)
o Add a new callback to get called on evbuffer_file_segment free
(e9f8feb yangacer, 64051b9)
o Expose event_base_foreach_event() as a public API. (84fd6d7 Roman
Puls, 232055e, ffe1643)
o Add an event_remove_timer() to remove timer on an event without
deleting it (e3b2e08)
o Make bufferevent_set_timeouts(bev, NULL, NULL) have plausible
semantics (9dee36b)
o Rename event_enable_lock_debuging() to ..._debugging(). (The old name
should still work.) (07e132e)
o Add missing implementation for event_enable_debug_logging (3b3e21d)
PORTABLE MONOTONIC TIMERS:
Libevent 2.1.2 includes internal support for monotonic timers on
(nearly) all supported platforms, including Windows, and OSX. Libevent
applications should now be more resilient to jumps forwards or backwards
in the system clock. Also, on Linux systems with epoll, we now
optionally support microsecond-level timeouts (whereas epoll only
supports millisecond-precision timeouts).
o Use mach_absolute_time() for monotonic clock support on OSX. (b8fd6f9)
o Do not track use_monotonic field when is no monotonic clock (cb653a0)
o EVENT_BASE_FLAG_PRECISE_TIMER indicates we want fine timer precision
(ddd69d3)
o On Linux, use CLOCK_MONOTONIC_COARSE by default (55780a7)
o Implement a GetTickCount-based monotonic timer for Windows (d5e1d5a)
o Refactor monotonic timer handling into a new type and set of
functions; add a gettimeofday-based ratcheting implementation (f5e4eb0)
o Add EVENT_PRECISE_TIMER environment var for selecting precise-but-slow
timer (a2598ec)
o Implement fast/precise monotonic clocks on Windows (2c47045)
o Simple unit tests for monotonic timers (630f077)
o Improve the monotonic-time unit test: make it check the step size (7428c78)
o When PRECISE_TIMERS is set with epoll, use timerfd for microsecond
precision (26c7582)
o Split out time-related evutil functions into a new evutil_time.c (c419485)
o Split out time-related prototypes into time-internal.h (71bca50)
o Add evutil_time.obj to Makefile.nmake (0ba0683)
o Avoid giving a spurious warning when timerfd support is unavailable
(1aaf9f0 Dave Hart)
o Make test_evutil_monotonic a little more tolerant (def3b83)
o Avoid unused-var warning on systems with clock_gettime but without
CLOCK_MONOTONIC_COARSE (9be5468)
EVENT_BASE_ONCE LEAKS:
If a callback added by event_base_once() is never invoked, Libevent no
longer leaks internal memory.
o Free dangling event_once objects on event_base_free() (c17dd59)
o Add a unit test in which an event is created with event_base_once()
but never fires (4343edf)
TESTING SUPPORT, FIXES AND IMPROVEMENTS:
Libevent now disables by default its unit tests that would touch the
network, or that tend to fail on heavily-loaded systems. To re-enable
them, invoke the ./test/regress program with the @all alias.
o Simplify test.sh code significantly. (9b856fd Ross Lagerwall)
o Make all tests that hit the network disabled by default (f2cea87)
o Avoid a resource leak on error in http client benchmark (ea92fba)
o Update to latest tinytest (911b4f0349377) (ef7c4f7)
o Avoid (unlikely) overflow in bench_httpclient.c (5671033)
o Shave 700 msec off the persistent_timeout_jump test (21205b8)
o Check return value of write() in regress.c (c8009d2)
o Make load-dependent monotonic timer tests off-by-default (2b6fe8b)
o Add deferred_cb_skew to list of timing-dependent tests (34c8f31)
o Avoid test -e; older shs don't have one. (f1bd938)
o Fix renegotiation test to work around openssl 1.0.1 bug (c2f3086)
o Fix a couple of compile warnings in the unit tests (5a9a014)
MISC:
o Change evutil_weakrand_() to avoid platform random() (e86af4b Nicholas
Marriott, 3aa4415)
INFRASTRUCTURE (Active-later events):
As a simplification and optimization to Libevent's "deferred callback"
logic (introduced in 2.0 to avoid callback recursion), Libevent now
treats all of its deferrable callback types using the same logic it uses
for active events. Now deferred events no longer cause priority
inversion, no longer require special code to cancel them, and so on.
o Refactor the callback part of an event into its own event_callback
type (cba59e5)
o Add "active later" event_callbacks to supersede deferred (745a63d)
o event_base_assert_ok: check value of event_active_count for
correctness (fec8bae)
o Replace deferred_cbs with event_callback-based implementation. (ae2b84b)
o Replace more deferred_cb names with event_callback (a4079aa)
o Give event_base_process_active a single exit path (581b5be)
o Restore our priority-inversion-prevention code with deferreds (c0e425a)
o Refactor event_persist_closure: raise and extract some common logic
(bec22b4)
o Remove the unused bits from EVLIST_ALL (9889a3d)

Changes in version 2.1.1-alpha (4 Apr 2012)
Libevent 2.1.1-alpha includes a number of new features and performance
improvements. The log below tries to organize them by rough area of
effect. It omits some commits which were pure bugfixes on other commits
listed below. For more detail, see the git changelogs. For more
insight, see the "whatsnew-2.1.txt" document included in the Libevent
2.1.1-alpha distribution.
Performance: Core
o Replace several TAILQ users with LIST. LIST can be a little faster than
TAILQ for cases where we don't need queue-like behavior. (f9db33d,

timeout (e47042f, 09cbc3d)
o Remove a needless base-notify when rescheduling the first timeout (77a96fd)
o Save a needless comparison when removing/adjusting timeouts (dd5189b)
o Possible optimization: split event_queue_insert/remove into
separate functions. needs testing (efc4dc5)
o Make event_count maintenance branchless at the expense of an
extra shift. Needs benchmarking (d1cee3b)
o In the 2.1 branch, let's try out lazy gettimeofday/clock_gettime
comparison (2a83ecc)

o Remove the eventqueue list and the ev_next pointers. (604569b 066775e)
Performance: Evbuffers
o Roughly 20% speed increase when line-draining a buffer using
EVBUFFER_EOL_CRLF (5dde0f0 Mina Naguib)

o Clean up error handling in epoll_apply_one_change() a little (2d55a19)
Performance: Evport backend

RAM. (4687ce4)
o evport: Remove a linear search over recent events when
reactivating them (0f77efe)
