Apple is taking the beta label off of Safari 4 today amid a flurry of news at WWDC. A public beta of the web browser has been available for Mac and Windows since February, and in fact when you go to the Safari download page, you're still greeted with a beta version of the browser. We're guessing the full version will be available later this afternoon. Update: It's available now.

Apple claims Safari 4 runs JavaScript up to 4.5 times faster than Safari 3, 4 times faster than Firefox 3, and 8 times faster than Internet Explorer 8. The company says the browser loads HTML web pages 3 times faster than Firefox 3, although the company admits that performance can vary from system to system. I'm going to venture a guess that it may differ from web page to web page as well.

When OS X Snow Leopard is released later this year, Apple says Safari will be able to run as a 64-bit application, boosting performance by up to 50%.

Safari 4 features a Google Chrome/Opera style new tab page which provides you with thumbnail shortcuts to pages you visit frequently. The browser also features full page zoom, and a smarter URL bar with auto-complete functionality.

Safari 4 is available for Windows XP, Vista, or mac OS X 10.4.11 or newer.

Update: It's worth pointing out that Safari 4 is also the first non-beta browser release to get a perfect score on the Acid3 test.

Update: Nope, sorry, nope...Chromium still beats Safari on V8 (rather soundly, at that)...Dromaeo results in in a few minutes! --Lee

Update: Ok, on Dromaeo the results were much closer. My Chromium Nightly Build won 26 categories while Safari claimed 23. I tried several Chrome Experiments, and they generally run much more smoothly on Chromium. --Lee
