This release features a lot of core improvements, the most important which is probably a complete refactoring of the magic.endpoint project, where now it's got much more readable code, in addition to making it easy to inject your own custom Content-Type handler, handling a custom payload of some sort as you see fit, in addition to also making it easy to inject Content-Type response handlers, creating the payload to return to the client.
The release also features some minor UX improvements, in particular in Hyper IDE. But most changes are in the core, making things faster, more easily maintained, and more readable for those wanting to look at the internal code parts of Magic.
