Last night, Apple seeded the eight beta version of OS X Mavericks 10.9.3 (build number: 13D45a) to developers.
Apple had released OS X Mavericks 10.9.2 in February, which included a fix for a critical SSL bug, along with other performance improvements. It also added a call waiting feature for FaceTime audio and video calls, and the ability to to block incoming iMessages from individual senders.
Apple had released six beta versions for OS X 10.9.2, so I expect Apple to release OS X 10.9.3 very soon.
Please let us know if you’ve found any other change in the comments below.
Thanks Tim for the tip!
