According to people familiar with the pre-release software, dubbed Safari 7.0.3 for OS X 10.9 Mavericks and Safari 6.1.3 for Mountain Lion and Lion, Apple is asking developers to focus on general website compatibility, push notifications and AutoFill enhancements.
Apple introduced Safari push notifications in version 7.0 of the Mac Web browser, allowing websites to deliver real-time breaking news, important updates and other content via Notification Center.
In addition, Apple is requesting testing of the Login AutoFill feature and generic extension compatibility, while credit card AutoFill is getting special treatment in the OS X Mavericks-only Safari update.
All three seeds can be downloaded individually from Apple’s Developer Center.
