In contrast to the latest developer preview of Mountain Lion, Safari 5.2 Update 3 carries a few bug fixes. New features and improvements include a SVG filter (scalable vector graphics), HTML5 media controllers, CSS filters, a redesigned Web Inspector, and a Web Audio API, according to Apple Insider.
The Xcode developer release - Xcode 4.4 Developer Preview 3 - includes an updated Apple LLVM Compiler version 4.0. Known issues with the release include problems downloading earlier versions of Xcode from the App Store, scheme editing problems and issues with linker and new load commands, writes Apple Insider.
