La mise à jour de Panther 10.3.9 contient Safari 1.3. Au menu :

Page Load Performance Safari 1.3 loads pages overall 35% faster than 1.2 as measured by IBench. In addition to improving the overall page load, Safari 1.3 will display content sooner than 1.2 did, so that subresources don't hold up the initial display of the page.

JavaScript Performance We have substantially improved the performance of the JavaScript engine in Safari. I encourage you to check out Safari 1.3 on this benchmark for example to see the improvement relative to 1.2.

HTML Editing Safari 1.3 supports HTML editing, both at the Objective-C WebKit API level and using contenteditable and designMode in a Web page. The new Mail app in Tiger uses WebKit for message composition. You can write apps that make use of WebKit's editing technology and deploy them on Panther and Tiger. __ Compatibility and Security__ Compatibility and security are our number one priority in WebCore, and Safari 1.3 has many important compatibility fixes. For example, percentage heights on blocks, tables and cells now work much better in Safari 1.3. min/max-width/height support has been added. More of the table-related CSS properties are now supported. DOM methods like getComputedStyle are now supported.

The DOM Exposed The entire level 2 DOM has been exposed a public API in Objective-C. This means various holes have been filled in Safari's DOM level 2 support. In addition to exposing the DOM to Objective-C, the JS objects that wrap DOM objects can also be accessed from Objective-C, allowing you to examine and edit the JS objects themselves to inject properties onto them that can then be accessed from your Web page.

XSLT Safari 1.3 on Panther now supports XSLT. 10.3.9 includes libxslt, and Safari uses this excellent library to handle XSLT processing instructions it encounters in Web pages.

Plugin Extensions For those of you writing WebKit apps, a new Objective-C WebKit plugin API is supported that lets you put Cocoa widgetry into the Web page more easily. In addition enhancements to the Netscape Plugin API (made in conjunction with Mozilla Foundation) have been implemented for plugins that require cross-browser compatibility.
