Safari 5.0.4 can be downloaded from Apple's site for Mac OS X 10.5 (Leopard), Mac OS X 10.6 (Snow Leopard), Windows XP, Windows Vista and Windows 7. Apple also offered an update to Safari 4.1.3 for customers still running Mac OS X 10.4, aka Tiger.
Mac OS X users will be notified of the new version automatically, while Windows users already running Safari will be alerted by the Apple Software Update tool.
