Safari is a web browser developed by Apple Inc. and included in Mac OS X. It was first released as a public beta on January 7, 2003, and was included as the default browser in Mac OS X v10.3. A beta version for Microsoft Windows was released for the first time on June 11, 2007 with support for Windows XP and Windows Vista. Safari has also been run unofficially on Linux under Wine, but the GUI and graphics do not render properly.
In February 2009 the beta for Safari 4 was released. This release includes a complete visual redesign and multiple new features such as full page zoom, speculative loading, ACID 3 compliance, a new and improved JavaScript engine and Cover Flow for websites.
