Android N: still no name yet, instead a PR stunt, where people can share name ideas with Google. Yawn.

Three claimed improvements in Android N:

- Vulcan (improved 3D rendering, lower CPU overhead than OpenGL)
- New JIT compiler (30-600% performance improvements; also, lower install latency, especially when you install a new OS version)
- Security (better "file based" encryption, fixing the mess of the media framework, and "seamless" updates that supposedly bug the user less)

Also, split-screen and "picture-in-picture" modes for viewing multiple apps at once.

And they've released a "beta quality" public release for Android N that runs on the usual list of Nexus devices.
