[Libevent-users] Please try out this source distribution before it becomes 2.0.11-stable?

[Nick Mathewson <nickm@xxxxxxxxxxxxx>]

Hi, all!

I'm hoping to put out a bugfix release on the libevent 2.0 series this
coming week.  With that in mind, I've put up a "dev" release that
contains almost exactly what I'm hoping to put into the stable
release.  If there are no complaints, I'll update the changelog,
documentation, and version number, and put this code out as
2.0.11-stable.

http://www.wangafu.net/~nickm/volatile/libevent-2.0.10-stable-dev.tar.gz

This is NOT the real Libevent 2.0.11-stable release!  Please do not
bake this into distributions, use it in production binaries, etc.  Of
course, I can't stop you, but if you do, I'll be sad.  Please wait for
the real thing to come out.  This version is just for testing.

Since 2.0 is stable, this is going to be a bugfix release.  I wish I
could say it fixed all the bugs in 2.0.10-stable, but there are still
some recalcitrant, tricky, or under-documented ones left.  So for now,
I'm not looking for bugs that exist in 2.0.10-stable and exist here
too... The  that bugs I *do* most want to know about by next week are
regressions against 2.0.10-stable?

 **That is, is there anything that works with 2.0.10-stable, but
breaks with this code?**

Sorry for all the dire warnings, but I really want to make sure that
each stable release is indeed a step ahead.  I can only do that with
your help.  Please give it a whirl and let me know if it breaks
anything for you that used to work with 2.0.10-stable.
