Following the release of a new 10.9.5 beta for developers, Apple today released Safari 7.0.6 for OS X Mavericks and Safari 6.1.6 for OS X Mountain Lion to the public, bringing new security fixes to the browser.
Apple has also previously seeded Safari 6.2 and Safari 7.1 for Mountain Lion/Mavericks to developers, and it's likely that update will see its public release alongside OS X Yosemite.
Update 2:00 PM PT: This post originally identified Safari 7.0.6 and Safari 6.1.6 as beta software available only to developers, which has since been corrected.
