I just upgraded our continuous integration server to TeamCity 8 EAP.
I am really excited about the new functionality to group projects and create subprojects which will be introduced in 8.0. It will greatly help organizing related projects.

If you never heard of TeamCity and are looking for a great CI server, I can only encourage you to give it a try. The reason for us to choose TeamCity was the great support for Ruby. It supports rvm, gemsets, bundler, rspec and integrates nicely in RubyMine through a plugin. It also has support for feature branches which is really great if you use Git with such a branching model.
