As of today a new version of MooTools is available. This includes MooTools Core and MooTools More. We've communicated a lot about changes for 2.0 but we also felt we had some good stuff that would benefit you directly which we wanted to add to the 1.x releases. This good stuff contains of course numerous bugfixes but mostly one important new feature for MooTools Core: Delegation. This 1.4 release should be fully backward compatible with the MooTools 1.2 and 1.3 series'.
We at the MooTools headquarters love GitHub for all its features which makes contributing and managing our code much easier than say, five years ago. GitHub is the place to be for all cool JavaScript projects which makes following your projects of interest a lot easier. When we moved to GitHub a long time ago, the ticket system was too basic to be a real solution. Fortunately this has since improved.
Especially the additions for milestones and assignees were important for us. With this in place GitHub issues can finally replace Lighthouse.
