I've been following along with Rails 5 for many months now and I've been tracking progress on updating GitLab in our issue tracker[1]. Feel free to look at the relevant merge requests and use them as guides to upgrade your own apps :) We're still on 4.2.6 since we have a few gems we're waiting on, but I hope to change that in a month or two! Favorite features are probably the various performance improvements and underlying improvements to the framework, as well as quiet_assets being moved into sprockets-rails. I also wanted to give a shoutout to BigBinary's Rails 5 series, since it's been great for finding out about new features[2].
