Google has released the third beta of Android P, which is supposed to be a “near-final” look at the OS before it’s completed later this summer. Google engineering VP Dave Burke calls the latest beta an “early release candidate build” that “takes us very close to what you’ll see in the final version of Android P.”

It’s not clear that this beta includes any new features — Burke only lists bug fixes and optimizations. The bigger deal here is really for developers, since system behaviors and APIs are supposed to be in a close to final state, so they can start to test apps and rely on how they’ll work.
