After seeding the first beta of the next versions of Safari for OS X a week ago, Apple has just seeded another pre-release version of Safari 7.0.3 and Safari 6.1.3 (Seed 2) to developers.

Apple provides the following focus areas for devs in the release notes:

Please focus testing on the following areas:

• General website compatibility

• Safari Push Notifications

• Login AutoFill

• Credit Card AutoFill (OS X Mavericks only) • Extension Compatibility

Safari 7.0.3 will arrive for Mavericks users while the 6.1.3 release is the latest for Mountain Lion users. The updates require the following:

Safari 6.1.3 for OS X Lion requires OS X 10.7.5 with Security Update 2013-002. Safari 6.1.3 for OS X Mountain Lion requires OS X 10.8.5. Safari 7.0.3 for OS X Mavericks requires OS X 10.9.2 and is also included in OS X 10.9.3.

Earlier this month Apple pushed updates for iTunes 11.1.6 and OS X 10.9.3 betas to developers. When released to the public, the new iTunes version will restore the ability to sync contacts and calendars to an iOS device, while OS X is expected to introduce the ability to output at 4k resolution with a 60Hz refresh rate on the latest MacBook Pro models.
