[Libevent-users] ANN: Libevent 2.0.13-stable is released

[Nick Mathewson <nickm@xxxxxxxxxxxxx>]

Hello, all!

Announcing Libevent 2.0.13-stable
=================================

Libevent 2.0.13-stable is now tagged and released.  The package is at
Sourceforge at:

 https://sourceforge.net/projects/levent/files/libevent/libevent-2.0/libevent-2.0.13-stable.tar.gz/download

and the signature file is at:

 https://sourceforge.net/projects/levent/files/libevent/libevent-2.0/libevent-2.0.13-stable.tar.gz.asc/download

They'll also be on monkey.org when Niels a chance to upload them.

What's New in Libevent 2.0.13-stable
====================================

This release fixes an important bug in the kqueue backend, some
evbuffer performance and correctness bugs, and a nasty bug with SSL
bufferevents in "filtering" mode. If you're using any of the features
mentioned in the changelog below, you may well want to upgrade from
2.0.12-stable.

There are also a few build fixes to make Libevent build correctly
on operating systems, compilers, and combinations of libraries that it
didn't build with before.  If you're affected by one of these, then
2.0.13-stable will make things more usable for you.

Finally, this release includes a substantial improvement to the
accuracy and completeness of the doxygen documentation in the Libevent
header files, especially in event.h, util.h, buffer.h, and
bufferevent.h.  There's still more work to be done, but there ought to
significantly fewer places where the doxygen leads the reader astray.

Here's the ChangeLog for this release.

Changes in version 2.0.13-stable (18 Jul 2011)

Fun facts about Libevent 2.0.13-stable
======================================

At first glance, this release seems to be a much bigger set of changes
than 2.0.12-stable.  The previous release had a 1107-line diff,
whereas the diff for this one is 4399 lines long.  But over 70% of
those changes are just documentation improvements.  If we exclude
those, the remaining diffs for this release amount to a much more
modest 1263 lines.
