Unlike Mozilla Firefox's version number bumping game, Apple recently released new Safari with real new features, and increased the version number from 5.0.5 to 5.1.
Safari 5.1 is available Mac OS X Snow Leopard (10.6.8) or later and Windows XP, Vista, and Windows 7. Safari 5.1 is included with OS X Lion. The update for the Web browser application added new features such as Reading List, Resume, as well as New Process Architecture and Better Privacy.
The update also includes a few security patches for both the Mac and Windows versions of the app. Both include a long list of Java-related patches, WebKit updates, fixes for maliciously crafted images, and more.
