Safari 7.0.3 and 6.1.3
Apple has released Safari 7.0.3 for users of OS X 10.9 Mavericks, with improvements to credit card autofill, a new preference to disable push notification prompts, and support for Web pages with generic top-level domains. Safari 7.0.3 also fixes issues that could block receipts of push notifications from Web sites and cause the search and address field to load content before the Return key was pressed. The update also brings a number of security improvements, notably strengthened Safari sandboxing. Among the security fixes are quite a few identified by the Google Chrome Security Team.
Simultaneously Apple released Safari 6.1.3 for users of 10.8 Mountain Lion and 10.7 Lion with improved Safari sandboxing, support for generic top-level domains, the search field bug fix, and the same security fixes. Both updates are available only through Software Update. (Free)
Wish Apple would still provide these standalone, I have a parental Mac on dialup I look after. Got the random satisfaction survey from Apple when trying to find, so expressed my displeasure.
Yeah, we've noticed that more things are being released only via Software Update too; it can be annoying.
