Safari 3.1 is available
In keeping with the 2008 tradition of Tuesday morning updates, Apple released Safari 3.1 today for both OS X and Windows -- marking the transition out of beta status for the Windows build. At 143MB (for the Leopard version, at least), there's a lot of changes, including
Improved JavaScript performance
Standards support, including CSS 3 web fonts, HTML 5 video and audio elements, and SVG advanced text
Developer benefits like editing CSS in the Web Inspector
Caps lock alert in password fields (Yay!)
There's much more, of course, and you can read the full change log here. Note that installation requires a restart. Apple's page describes Safari as "the world's fastest browser," but of course your mileage may vary.
Thanks to everyone who sent this in.
