We’re only partway into that project. We are currently in phase 1 of three. Sometime this year the IDE and the groovy cloud are going away. some of the IDE functions will probably continue in some other form, but code authors will now have to not just write their own custom smart apps, but host them as well.
There have been several official announcements about this.
We don’t yet know all the details of what’s coming, which does complicate things, but there is a new developer section of the forum where you can ask questions and find more resources.
