Update expected to include FaceTime improvements, fix for SSL vulnerability
Apple has started seeding a pre-release version of OS X 10.9.2 to some of its own staff, sources tell AppleInsider. The code is listed as build 13C64, and is thought to foreshadow an imminent public release. Significantly the update is said to include a number of important changes, including the ability to block individuals in Messages, audio calls and call waiting for FaceTime, and a promised fix for SSL security.
Fixes for Mail should improve the accuracy of unread message counts, and deal with email failing to download from some providers. Apple is also said to be solving problems with audio distortion, connecting to file servers using SMB2, and disconnections from VPN networks. VoiceOver navigation should be better for both Mail and Finder.
Point releases with feature additions have become relatively rare since Apple switched to an annual OS X upgrade cycle. Under the new system, it may make more sense to focus labor on the next OS, and simply cope with bugs and device support in the interim.
