Apple has seeded the fourth beta version of OS X 10.11.2 to developers. It can be found now at the Mac Developer Resource Center, as well as through the Mac App Store on a Mac running the previous beta.
A new update for the OS X 10.11.2 Public Beta is also available. Members of Apple's Beta Software Program can download this new version from the Mac App Store now.
What changes will come with the public release of OS X 10.11.2 are not yet clear, though it will likely contain a number of bug fixes and performance improvements to the overall OS X experience.
