This release contains only bug fixes.
Please note, that you should use dist archives, i.e. libevent-2.1.11-stable.tar.gz, not the sources generated by github automatically
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.
P.S. please use dist archives, i.e. libevent-2.1.11-stable.tar.gz (not the sources generated by github automatically)
Finally 2.1.x stable release - 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).
I'm not going to attach ChangeLog here (since it is pretty large), but for those who is curios you can find it here: https://raw.github.com/libevent/libevent/release-2.1.10-stable/ChangeLog
It has been tested in next environment (with both cmake/autotools build systems):
As usual, many thanks to everyone who helped with debugging/backporting/reporting/testing and fixing issues!
(please note, that you need "libevent-2.1.10-stable.tar.gz" not "Source code" links, since later requires running ./autogen.sh)
New 2.1.x release is out - 2.1.9-beta. The reason why it is beta, is because it is better to have few weeks (or more) to know about possible problems (although I'm pretty sure that it is good enough to be stable).
2.1.9 contains almost all patches from 2.2 (since 2.2 contains almost bug fixes only, except I guess only few patches or so), and it is pretty stable in regression tests, but not without failures (some flackiness still presented), although this is not the problem of libevent itself, but it's tests.
I'm not going to attach ChangeLog here (since it is pretty large), but for those who is curios you can find it here: https://raw.github.com/libevent/libevent/release-2.1.9-beta/ChangeLog
It has been tested in next environment (with both cmake/autotools build systems):
As usual, many thanks (especially for those how reminded about making new releases) to everyone who helped with debugging/backporting/reporting/testing and fixing issues!
(please note, that you need "libevent-2.1.9-beta.tar.gz" not "Source code" links, since later requires running ./autogen.sh)
First of let me say that everyone who still uses 2.0.x should strongly consider switching to 2.1.x releases, since 2.0.x will not contain all the bug fixes, because it can be pretty hard to backport them (for example 2.0.x does not support openssl 1.1)
Secondly, this release is beta, because since the last release it has been along time, so we need sometime to stabilize things a little, and if none of you will find something odd the it will be marked as 2.0.24-stable.
Many thanks to all who reported, fixed and helped with debugging issues and backporting patches!
