Changes in version 2.1.11-stable
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.
o Revert "Protect min_heap_push_ against integer overflow."
functionality:
o evdns: add new options -- so-rcvbuf/so-sndbuf
build:
o Change autoconf version to 2.62 and automake version to 1.11.2
o cmake: install shared library only if it was requested
o Missing <winerror.h> on win7/MinGW(MINGW32_NT-6.1)/MSYS
o cmake: set library names to be the same as with autotools
o Enable _GNU_SOURCE for Android
o Enable kqueue for APPLE targets
o autotools: do not install bufferevent_ssl.h under --disable-openssl
o cmake: link against shell32.lib/advapi32.lib
o Add README.md into dist archive
o cmake: add missing autotools targets (doxygen, uninstall, event_rpcgen.py)
o m4/libevent_openssl.m4: fix detection of openssl
o Fix detection of the __has_attribute() for apple clang [ci skip]
lib:
o buffer: fix possible NULL dereference in evbuffer_setcb() on ENOMEM
o Warn if forked from the event loop during event_reinit()
o evutil: set the have_checked_interfaces in evutil_check_interfaces()
samples:
o https-client: correction error checking
Changes in version 2.1.10-stable
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).

o Link test/regress with event_core/event_extra over event
tests:
o Use kill() over raise() for raising the signal (fixes osx 10.14 with
kqueue)
o tinytest: implement per-test timeout (via alarm() under !win32 only)
Changes in version 2.1.9-beta
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).
