The release notes again ask developers to focus on Graphics Drivers, Audio, Safari, Mail and Contacts & Calendar sync over USB in iTunes. As spotted in earlier releases, the final release will likely add support for 4K displays as well as add a new “Retina” output mode for select retina MacBook Pro models.
Apple last public release was OS X Mavericks 10.9.2, which debuted in February and included a fix for a critical SSL bug, along with other bug fixes and performance improvements. That earlier version also enabled an audio and video call waiting option for FaceTime and added the ability to block incoming iMessages from individual senders.
With near weekly updates, Apple is picking up of the pace of its beta releases, a pattern that suggests the company may roll out OS X 10.9.3 very soon.
