New from Apple is Safari 5.1 for Mac OS X 10.6 Snow Leopard, which brings the company’s Web browser on par with the version installed on 10.7 Lion. Safari 5.1 includes several new features, including Reading List, which enables users to create a list of Web pages they can then examine at a later date; Resume, which automatically restores all open windows and tabs when you relaunch Safari; and a Privacy pane that makes it easier to remove browsing data from your system. In addition, Safari 5.1 supports a new process architecture that separates the user interface from rendering operations, providing better performance and more stability, particularly when using third-party plug-ins. Other improvements highlighted by Apple include private auto-fill, better search functionality, drag-and-drop for moving files from the Downloads window, improved support for modern Web technologies like HTML5 and CSS3, and new APIs for extension developers.
Separately, the company has also released Safari 5.0.6 for Mac OS X 10.5 Leopard, which focuses exclusively on fixing issues related to the rendering of HTML5 content, the layout of several Web sites, and general stability. (Free updates; Safari 5.1: 47.47 MB; Safari 5.0.6: 52.51 MB)
