Apple has released Safari 5.2 Update 3 to developers for testing purposes. This follows the release of OS X 10.8 Mountain Lion Developer Preview 3 and Xcode 4.4 build 45155i earlier today.
We’ve been informed that this build includes a couple of new features for developers including scalable vector graphics filters and a redesigned web inspector.
Using SVG Filters, you can combine several filter primitive elements and light source elements into a single sophisticated filter, which can then be applied to any SVG element.
Redesigned Web Inspector
Developers can download the new release from the Apple Developer Center.
