Great news for Web developers and users, Safari 4 has a public beta, and it comes with some nice features such as: tabs on top and top sites (a la Chrome), full page zoom, history view, and ARIA Support.

But, what about the engine? Here are some of the features as Apple see’s them:
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.
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.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.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.Nitro JavaScript Engine
Safari 4 introduces 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.HTML 5 Offline Support
Web developers can now create applications that you can use even when you don’t have access to the Internet. Thanks to HTML 5 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.
