Marionette v4 beta

The new version is on it’s way here and is a simpler API with plenty of performance improvements. We’ll be hard at work testing it in the wild during the beta, but unless anything surprising comes up, expect a full release in the coming weeks. Also watch a more in-depth blog post of the changes with the full release.
