Apple released minor updates to Safari for the current and two most recent OS X versions. Mountain Lion (OS X 10.8.5) users will see an update to Safari v6.2.1, Mavericks (10.9.x) users will see Safari 7.1.1 available for update, and Yosemite users (10.10) will get Safari 8.0.1. The releases share a variety of bug and security fixes, and add the ability to import usernames and passwords from Firefox.
All the updates are available through Software Update in the Mac App Store, and fix an issue that was preventing users from syncing their web histories across devices unless iCloud Drive was turned on. Also fixed was a problem that cause saved passwords not to be filled in automatically if two or more devices were added to iCloud Keychain.
In addition to the bug fixes, the new versions also improve WebGL performance on Macs with Retina displays, and add the aforementioned importing of saved logins from Firefox. The updates also address three WebKit vulnerabilities that could conceivably have been exploited to allow attackers to take control of the browser. The new versions were issued after three weeks of testing by developers in beta form.
