Hub2 API changes?

Now that hub2 is here I’d like to be able to control my house locally. Are there new APIs and/or a way to run my app locally? If not then what does hub2 give me?

There have been some backend changes but nothing specific to V2.

Currently only certain non custom device types (some switches) and the SmartThings Smart Lighting smart app can run locally. Lots of info on V2 and whatnot already posted.
