The good news is, the
Safari 5.0.2 update fixes a passel of bugs and outstanding security issues. The bad news: like all Safari updates, which replace the underlying Webkit framework used by many Mac OS X apps to render HTML, this 39 MB update requires a restart. There's also a
4.1.2 update for users still on Mac OS X 10.4 Tiger.
Apple's notes on the update say that it "contains improvements to compatibility and security" including:
• Fixes an issue that could prevent users from submitting web forms
• Fixes an issue that could cause web content to display incorrectly when viewing a Google Image result with Flash
• 10.1 installed
• Establishes an encrypted, authenticated connection to the Safari Extensions Gallery
