On Wednesday, Apple updated the developer versions of Safari with two new betas aimed at users of older OS X versions, specifically 10.8 (Mountain Lion) and 10.9 (Mavericks). The new versions follow a slight update to the current Safari versions for OS X 10.8 and later that contains several WebKit fixes for security issues. Version 7.15 is for Mavericks, while Mountain Lion owners will see only version 6.2.5.
