It was Apple’s big day with plenty of Mac and iPhone related news, but there was a lone piece of Windows-compatible software that also made it out – Safari 4.
Safari 4 includes HTML 5 support for offline technologies and support for advanced CSS Effects. Apple at the WWDC was also proud to point out that Safari 4 is the first browser to pass the Web Standards Project's Acid3 test.
Safari is built off of WebKit, which is the open source browser engine that’s also used by popular mobile browsers and even Google’s Chrome. It’s interesting that Apple chose to compare Safari 4 against IE8 and Firefox 3, but left out comparisons with Chrome 2.
Both PC and Mac users can download Safari 4 free of charge here (as soon as Apple updates the site).
