Safari 5, which is expected to be released during WWDC, beginning June 7, is rumored to have integrated Bing Search, HTML 5 support, and a new clutter free reader.

Other rumored features include a timeline panel in the Web Inspector for developers, a search history with date, smarter address fields, and a private browsing icon. Safari 5 is supposed to be 25 percent faster than Safari 4 in DNS prefetching and JavaScript.

The HTML 5 support would include several new features including geolocation, and full screen video with closed captions.
