Apple Releases Safari 5

ByMike Moffit

With Apple’s announcement of the revolutionary iPhone 4 yesterday, it would be easy to overlook the release of Safari 5 that coincided with it. While certainly not as glamorous as Apple’s latest device, the newest version of Safari does bring some changes that will give it a serious leg up in the browser wars.

Performance is easily the biggest deciding factor when choosing a browser, and Apple has upgraded Safari with a faster “Nitro” engine to keep themselves ahead of the game. Apple claims Safari 5 will run JavaScript 30 percent faster than Safari 4, 3 percent faster than Chrome 5.0 and more than twice as fast as Firefox 3.6.

In addition to significant speed boosts, Safari 5 also includes the Safari Reader. This utility automatically detects if you are browsing a page with an article on it, and allows you to view it in a continuous and clutter-free manner. To enable Safari Reader, simply navigate to an applicable page and click the Reader icon in the Smart Address Field. Upon doing so, onscreen controls, similar to those seen when viewing a PDF, will appear and let you email, print, and zoom. Safari Reader even saves text settings so font size is the same if you revisit the page.

Though not apparent by simply glancing at the UI, Safari 5 also includes a robust set of HTML5 tweaks under the hood. The new browser brings over a dozen new features including full-screen mode and closed captioning for HTML5 video as well as HTML5 geolocation. To view some examples of the HTML5 web standard in action, check out Apple’s showcase of demos here.

Other more subtle refinements include DNS prefetching and improved catching. DNS prefetching means that if you are viewing a web page with links, Safari detects them and looks them up behind the scenes. When you click a link, the page loads faster as a result. A web cache is essentially an index of pages previously viewed. Since Safari 5’s cache has been expanded, more pages fit into it and load faster upon being revisited.

Appending the aforementioned features are other upgrades such as a smarter address field, integrated Bing search, hardware acceleration for Windows and an improved web inspector. Safari 5 is available today, and is a free download for Mac + PC. Download it here.

Please Note: The requirements for Safari 5 are either Mac OS 10.5 + or Windows XP SP3 +

  • iPhoto '11 New Features Overview

    iPhoto ’11 was released today at Apple’s Back to Mac press conference as part of the new iLife ’11. Some of the standout new features include:

    New Full-Screen Modes iOS-like full-screen mode for editing and viewing photos Use every inch of your display to browse and edit your photos. This is much more advanced than the full-screen editing available in previous versions of iPhoto. More screen real estate means a bigger workspace for perfecting each shot or creating nifty iPhoto projects.

    Facebook Enhancements – Share your photos and view comments without ever leaving iPhoto. iPhoto and Facebook are now even better friends. iPhoto even shows you all of your Facebook photo albums, including the ones you published using another application. You’ll always know which photos you shared (or didn’t share) on Facebook, because iPhoto keeps track of that for you.

    Emailing Photos – iPhoto now includes eight Apple-designed themes that you customize with your own images and words. Rearrange photos with a simple drag and drop, adjust the image mask, or change the size and style of your text. Plus, iPhoto optimizes your message so it’s never too big to send. iPhoto also works with popular email services like MobileMe, Gmail, Yahoo! Mail, Windows Live Hotmail, and AOL. And since iPhoto keeps track of all your email messages with photos, you’re free to open a sent message, make changes, and share it with someone new, anytime you want.

    New Slideshows – New animated themes — like Holiday Mobile, Places, and Reflections — give your photos movement and help you avoid typical, photo-by-photo, fade-in, fade-out slideshows. Each shot is centered and framed perfectly, thanks to face detection. And the animated themes include their own soundtracks, so your photos and music play together flawlessly.

    Big Leap in Books iPhoto ’11 makes it even easier to create professional-quality books using your own photos. Building your book starts with a new dynamic Theme browser. Pick a theme, and an even smarter Autoflow instantly goes to work, placing your images for you. Higher-rated images are featured more prominently. Photos taken on the same day appear together. And all the while, face detection ensures that photos of people are cropped and framed properly. Change the background color, font, layout, and more. Add eye-popping full-bleed, two-page spreads.

    Letterpress Cards – For the first time, traditional printing techniques join modern digital photography on a large scale. With iPhoto ’11, you can create custom letterpress cards personalized with your photos and text. Each iPhoto letterpress card is made from premium paper and produced using a centuries-old printing method. Then it’s digitally processed with your photos and text. iPhoto letterpress cards are available in 15 beautifully crafted themes complete with matching envelope. There’s just something about the elegant look and feel of a letterpress card.

    As John Gruber from Daring Fireball tweeted: “Can you imagine any other computer company offering letterpress as a mass-market printing technology?”

    iLife is a $49 upgrade for existing Mac users, and comes free with every new Mac. It’ll be listed on our site for sale and shipment shortly.
