Moved to "adopt": Gitlab has proven to be a very useful tool for code and the collaboration around it. With Gitlab CI there is also a powerful tool to automate continuous integration and delivery.
We are migrating more and more repositories from gitolite, even from SVN to gitlab, as it provides a more stable and user friendly interface.
Gitlab also makes user/permission handling easier than our old gitolite. We don't need the IT team every time a new repository needs to be set up.
