Apple seeds first build of Safari 9.0 to developers

Apple has released the first developer preview of Safari 9.0. This update is available to developers via the Mac App Store on OS X Yosemite, in the Updates section.

Safari 9.0 is expected to be available later this year, and will contain a number of enhancements to the Safari experience. This includes better performance, as expected, but users will also be able to pin tabs, mute all of your tabs or specific tabs, and AirPlay web video without sharing your whole screen.

Developers can grab Safari 9.0 Seed 1 right now from the Mac App Store.
