New Safari 5 features include Safari Reader for reading articles on the web without distraction, a claimed 30 percent performance increase over Safari 4 (based on All testing conducted by Apple last month on an iMac 3.06 GHz Intel Core 2 Duo system running Mac OS X 10.6.3, with 4GB of RAM), and the ability to choose Google, Yahoo! or Bing as the search service powering Safari’s search field. Safari 5 also includes improved developer tools and supports more than a dozen new HTML5 technologies that will appeal to web developers, who can now create secure Safari Extensions to customize and enhance browsing experience.
Apple’s senior vice president of Worldwide Product Marketing Phil Schiller notes that: “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, scrollable view without 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, with options to enlarge, print or send via email.
Safari 5's new Nitro JavaScript engine, on the Mac version is claimed by Apple to run JavaScript 30 percent faster than Safari 4, three percent faster than Chrome 5.0, and over twice as fast as Firefox 3.6 (JavaScript benchmark based on the SunSpider 0.9.1 JavaScript Performance test), to load new webpages faster using Domain Name System (DNS) prefetching, and include improved caching of previously viewed pages to return to them more quickly.
This new version of Safari adds more than a dozen powerful HTML5 features including full screen playback and closed captions for HTML5 video, Geolocation, HTML5 sectioning elements, HTML5 draggable attribute, HTML5 forms validation, HTML5 Ruby, HTML5 AJAX History, EventSource and WebSocket.
A 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.

Appendix: Safari 5 Feature Set In More Detail
VoiceOver Screen Reader
Safari features built-in support for Apple’s VoiceOver screen reader in Mac OS X. VoiceOver describes aloud what appears on your screen and reads the text and links of websites. Using VoiceOver, you can completely control the computer with the keyboard instead of the mouse.
ARIA Support
Safari supports Accessible Rich Internet Applications (ARIA). The ARIA standard helps web developers make dynamic web content more accessible for people with disabilities. With ARIA, sites taking advantage of advanced technologies like AJAX and JavaScript can now easily interoperate with assistive technologies.
Enhanced Keyboard Navigation
Thanks to the enhanced keyboard navigation options in Safari, you can navigate the web without a mouse. Press the Tab key, and Safari jumps to the next password field, pop-up menu, or input field. For increased keyboard control, you can hold down the Option key while tabbing to have Safari skip through every link on the page. And if you press the Return key, Safari opens the highlighted link, letting you “point and click” with just a few keystrokes.
Full-Page Zoom
Zoom in or out on web content using keyboard shortcuts, Multi-Touch gestures, or the Zoom toolbar button for more comfortable reading. Images and graphics scale up while your text remains razor sharp, keeping the web page layout consistent as you zoom. To add the Zoom button to your toolbar, simply choose Customize toolbar from the View menu and drag the button onto your toolbar.
Zoom Text Only
You can choose to zoom in on only the text when you take a closer look at a web page.
Custom Style Sheets
Apply custom style sheets — that you download or create yourself — that set default fonts, font sizes, colors, and contrast, making your favorite websites more readable.
Minimum Font Size
If you find that text on some websites is too small to read (such as photo captions or fine print) Safari can increase the font size to make it more legible. Just set the minimum font size in the Advanced pane of Safari preferences.
Next-Generation Standards Support
Safari continues to lead the way, implementing the latest innovative web standards and enabling next-generation Internet experiences. With support for HTML5 media tags, CSS animation, and CSS effects, web designers can create rich, interactive web applications using natively supported web standards. A standards-compliant browser, Safari renders current and future web applications as they were meant to be seen
.
CSS Animation
CSS animation — an open standard that brings a new level of interactivity to the web — lets web designers scale, rotate, fade, and skew web elements to create cutting-edge websites. Safari is the first web browser to support CSS animation.
CSS Effects
Pioneered by Safari, CSS effects help developers add polish to websites by stylizing images and photos with eye-catching gradients, precise masks, and stunning reflections that require only a few lines of code.
CSS3 Web Fonts
CSS3 web fonts allow web designers to create stunning websites using the fonts they prefer rather than restricting themselves to “web-safe fonts.” Safari is the first web browser to automatically recognize websites that use custom fonts, downloading them as they’re needed.
CSS Canvas
Using CSS Canvas, web designers can position canvas elements anywhere an image can be placed using CSS. Safari is the first web browser to support CSS Canvas.
HTML5 Media Support
Websites can now deliver rich, interactive media as easily as they deliver images. The first browser to support HTML5 audio and video tags, Safari helps developers create media-rich sites that don’t require additional plug-ins. The media tags also offer a rich scripting API, allowing developers to create powerful new controls as well as controls that match the style of the page.
HTML5 Offline Support
Web developers can now create applications that you can use even when you don’t have access to the Internet. Thanks to HTML5 offline support, designers can build web applications that store themselves on your computer, where you have immediate access to them. Along with the application, web developers can also choose to store the application’s data on your system, so you always have the information you need. Applications and data can be stored in a traditional SQL-like database serving as an application cache or as a “super cookie,” which stores data in the familiar cookie format.
HTML Canvas
Originally invented by Apple for Mac OS X Dashboard, HTML Canvas technology allows web designers to specify an area in HTML that can be dynamically stylized by a JavaScript program. Safari was the first web browser to support
HTML 4.01 Support
Safari supports HTML 4.01, the authoring language that defines the structure and layout of web documents.
WebKit
WebKit, the open source rendering engine introduced by Apple, powers Safari on iPhone and iPod touch and Safari 4 on Mac and Windows systems. WebKit features blazing performance and extensive standards support, and because it’s open source, developers can examine WebKit code and contribute to the community.
Acid 2 Compliance
Designed by the Web Standards Project, Acid tests determine whether a web browser complies with emerging Internet standards. Acid 2 tests for compatibility with new features in the HTML, CSS, and PNG standards. Pioneering the standardization effort, Safari passed Acid 2 on October 27, 2005, two-and-a-half years before any other popular browser.
Acid 3 Compliance
Safari is the first — and only — web browser to pass Acid 3. Acid 3 tests a browser’s ability to fully render pages using the web standards used to build dynamic, next-generation websites, including CSS, JavaScript, XML, and SVG.
Acid 3, 100/100
Nitro JavaScript Engine
Safari 4 introduced the Nitro JavaScript engine, an advanced bytecode JavaScript engine that makes web browsing even faster. In fact, Safari 4 executes JavaScript up to 6 times faster than Internet Explorer 8 and up to 4 times faster than Firefox 3.1.
JavaScript Support
Safari supports ECMA 262 version 3, the latest edition of the JavaScript standard. JavaScript powers many dynamic features on the web and has served as a key component in the rise of highly interactive AJAX applications.
Speculative Loading
Safari loads the documents, scripts, and style information required to view a web page ahead of time, so they’re ready when you need them.
SVG 1.1 Support
By taking advantage of the Scalable Vector Graphics (SVG) support in Safari, web developers can create fonts, graphic elements, and animations on the fly that look great no matter how large or small they’re sized. For example, mapping sites often use SVG to draw driving directions based on your location and destination.
ICC Color Profile Support
Safari uses advanced color management technology to deliver web images with rich, accurate color. In fact, it was the first browser to support International Color Consortium (ICC) profiles and has done so from day one, so the photos and images you see in your browser stay true to the original.
Plug-in Support
Plug-ins are add-ons that expand a browser’s capabilities. Because it supports the standard Netscape plug-in architecture, Safari works with the full range of popular Internet plug-ins, including Flash, Shockwave, and QuickTime.
Scriptable Plug-ins
Thanks to its support for scriptable plug-ins, Safari lets developers create plug-ins that interact with standard elements on a page. For example, a plug-in could allow you to customize the appearance of a car. As you add or remove options, the scriptable plug-in could update the sticker price of the car.
Java Support
Enjoy running Java applets on the web thanks to Java support in Safari.
XML 1.0 Support
Extensible Markup Language (XML) is a popular open industry standard for creating, managing, and sharing structured data. Because native XML support is built into Safari, JavaScript programs can efficiently read XML data feeds.
LiveConnect Support
Safari supports LiveConnect to ensure compatibility with popular enterprise web applications. LiveConnect allows Java and JavaScript to work together to deliver a more seamless browsing experience.
