Apple showed off Safari 7 at WWDC today, which includes a cleaner design, new features and performance improvements. Safari 7 uses much less processor power and memory than its predecessor and competitors, and it features better integration with Reading List and a sidebar for bookmarks. There’s also a “shared links” tab for browsing links posted to social networks like Twitter and LinkedIn.
Also included in Safari 7 is a new iCloud Keychain feature that generates and stores secure passwords across all of your devices, much like 1Password.

Safari 7 will be included in OS X Mavericks.
