Apple on Monday pushed out a four-pack of new beta releases for all of its major platforms — all of which are expected to be minor updates to squash bugs and improve security.
The third beta of iOS 10.2.1 and the third beta of macOS Sierra 10.12.3 are both now available to registered developers. iOS 10.2.1 beta 3 is identified as build 14D23, and macOS Sierra 10.12.3 beta 3 is build 16D25a.
In addition, tvOS 10.1.1 beta 2 is also available, with the build number 14U711. Finally, watchOS 3.1.3 has also been issued a second beta, identified as build 14S959.
The new betas are the first to arrive since Dec. 20, when the second builds of iOS 10.2.1 and macOS 10.12.3 were provided to testers.
It's not clear what changes are in the upcoming releases, though they are likely to focus solely on maintenance. Release notes from Apple mention "stability, compatibility and security" improvements.
