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.
ABI breakage:
o Protect min_heap_push_ against integer overflow. (8c899768 Tobias Stoeckmann)
o Revert "Protect min_heap_push_ against integer overflow." (18104973 Azat Khuzhin)
functionality:
o evdns: add new options -- so-rcvbuf/so-sndbuf (546a366c Azat Khuzhin)
build:

o Missing <winerror.h> on win7/MinGW(MINGW32_NT-6.1)/MSYS (9559349c yuangongji)
o cmake: set library names to be the same as with autotools (305251b9 yuangongji)

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).
