On the heels of the release of the second developer beta, Apple has seeded a new public beta build of OS X 10.11.2 to members of the Beta Software Program. It is available through the Update section of the Mac App Store.
It's not yet clear what changes OS X 10.11.2 brings along. It's likely that it will focus on bug fixes and performance improvements. Apple seeded the third developer beta of OS X 10.11.2 earlier this week.
