Perhaps most significant among Safari version 7.0.3's new features is greater control over push notifications, which in the past required per-website management.
With the latest release, users can simply uncheck a box for "Allow websites to ask for permission to send push notifications," which effectively disables all incoming push attempts. In addition, the update includes a fix to an issue that could block the receipt of push notifications.
Support for webpages with new top-level domains, like ".cab" and ".clothing," has also been added, allowing Safari to move directly to a webpage instead of initiating a Web search.
Other fixes include an problem that could cause a webpage to load prematurely when typing a search term into the address field, credit card autofill compatibility and several security issues.
Safari 7.0.3, or Safari 6.1.3 for those running older OS X versions, is a free download from the Mac App Store or Software Update.
