You can download and install libevent using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install libevent
The libevent port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
For the latest released version of Libevent, see the official website at http://libevent.org/ .
There's a pretty good work-in-progress manual up at http://www.wangafu.net/~nickm/libevent-book/ .
For the latest development versions of Libevent, access our Git repository via
$ git clone https://github.com/libevent/libevent.git
You can browse the git repository online at:

To report bugs, issues, or ask for new features:
Patches: https://github.com/libevent/libevent/pulls
OK, those are not really patches. You fork, modify, and hit the "Create Pull Request" button. You can still submit normal git patches via the mailing list.
Bugs, Features [RFC], and Issues: https://github.com/libevent/libevent/issues
Or you can do it via the mailing list.
There's also a libevent-users mailing list for talking about Libevent use and development:
