Apple Releases Safari 5

Safari 5 is going live. The new (and somehow unexpected after no mention at the keynote) Safari update features an improved Javascript engine (30% faster), a Reader button in the Address Bar and improved HTML5 support.

The new Javascript engine called “Nitro” loads pages faster using DNS prefetching. Apple says that Safari 5 runs Javascript 30% faster than Safari 4, 3% faster than Chrome 5.0 and twice as fast as Firefox.

As for HTML5 support, Safari 5 introduces full screen playback and closed captions for videos. Other HTML5 features include: HTML5 Geolocation, HTML5 AJAX History, HTML5 sectioning elements, HTML5 forms validation, HTML5 draggable attribute, HTML5 Ruby, EventSource and WebSocket.

Safari 5 also introduces the much rumored “Reader” feature, which just like Instapaper seems to be able to pull text from an article and display it in an elegant, clutter free layout.

Last, Safari 5 finally comes with extensions, which developers can start building today using open web technologies such as HTML5, CSS and Javascript. To enhance security of extensions Apple has decided to sandbox them with a digital certificate signed from Apple. There’s also a new feature built in Safari called “Extension Builder” which will help developers create and test addons directly within the app.

[UPDATING]

Update #1: The update still doesn’t show up in Software Update. Is it propagating online, or is this just an Apple PR fail? More as this develops.

Update #2: The PR release first appeared on Pr Newswire and now it’s gone. What’s going on, Apple?

Update#3: It’s now live over apple.com/safari. Go download!

Check out the official press release below.

SAN FRANCISCO, June 7 /PRNewswire-FirstCall/ – Apple® today released Safari® 5, the latest version of the world’s fastest and most innovative web browser, featuring the new Safari Reader for reading articles on the web without distraction, a 30 percent performance increase over Safari 4,* and the ability to choose Google, Yahoo! or Bing as the search service powering Safari’s search field. Available for both Mac® and Windows, Safari 5 includes improved developer tools and supports more than a dozen new HTML5 technologies that allow web developers to create rich, dynamic websites. With Safari 5, developers can now create secure Safari Extensions to customize and enhance the browsing experience.

“Safari continues to lead the pack in performance, innovation and standards support,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “Safari now runs on over 200 million devices worldwide and its open source WebKit engine runs on over 500 million devices.”

Safari Reader makes it easy to read single and multipage articles on the web by presenting them in a new, scrollable view without any additional content or clutter. When Safari 5 detects an article, users can click on the Reader icon in the Smart Address Field to display the entire article for clear, uninterrupted reading with options to enlarge, print or send via email.

Powered by the Nitro JavaScript engine, Safari 5 on the Mac runs JavaScript 30 percent faster than Safari 4, three percent faster than Chrome 5.0, and over twice as fast as Firefox 3.6.* Safari 5 loads new webpages faster using Domain Name System (DNS) prefetching, and improves the caching of previously viewed pages to return to them more quickly.

Safari 5 adds more than a dozen powerful HTML5 features that allow web developers to create media-rich experiences, including full screen playback and closed captions for HTML5 video. Other new HTML5 features in Safari 5 include HTML5 Geolocation, HTML5 sectioning elements, HTML5 draggable attribute, HTML5 forms validation, HTML5 Ruby, HTML5 AJAX History, EventSource and WebSocket.

The new, free Safari Developer Program allows developers to customize and enhance Safari 5 with extensions based on standard web technologies like HTML5, CSS3 and JavaScript. The Extension Builder, new in Safari 5, simplifies the development, installation and packaging of extensions. For enhanced security and stability, Safari Extensions are sandboxed, signed with a digital certificate from Apple and run solely in the browser.
