"Apple created Safari to bring innovation, speed and open standards back into web browsers, and today it takes another big step forward," said Philip Schiller, Apple's senior vice president of Worldwide Product Marketing. "Safari 4 is the fastest and most efficient browser for Mac and Windows, with great integration of HTML 5 and CSS 3 web standards that enables the next generation of interactive web applications."
Safari 4 also represents the latest chapter in Apple's efforts to maintain its leadership role in defining and implementing web standards, with built in support for HTML 5 and CSS 3 — two technologies critical in supporting an entirely new class of web applications that feature rich media, graphics and fonts.
Safari 4 Beta tracks the sites you browse and ranks your favorites, presenting up to 24 thumbnails on a single page.
Specifically, the Cupertino-based company said the new browser includes HTML 5 support for offline technologies so web-based applications can store information locally without an Internet connection. A recent technology demonstration by Google highlighted the advantages this technology when it showed off a version of Gmail running offline on the iPhone's mobile version of Safari, which already includes support for some HTML 5 standards.
Safari for Mac, Windows, iPhone and iPod touch are all built on Apple's WebKit, which the company has billed the "world's fastest and most advanced browser engine." Apple developed WebKit as an open source project to create the world's best browser engine and to advance the adoption of modern web standards. Most recently, WebKit led the introduction of HTML 5 and CSS 3 web standards and is known for its fast, modern code-base. Some of the industry's newest browsers are based on WebKit including Google Chrome, the Google Android browser, the Nokia Series 60 browser and Palm webOS.
