Apple today released 10.7.4, the fourth minor update to Lion, and one that squashes a number of bugs and patches a security hole.
Among the fixes is one for Apple's FileVault data encryption technology, which cropped up in an earlier update. That issue kept user passwords in a log file that was stored in plain text if a user had upgraded from past versions of OS X.
Other notable changes include a new version of Safari (version 5.1.6), which Apple says is more stable. Once users install the OS X update, they can get Safari 5.1.7, which has a new security feature that checks to see if a user has an outdated version of Adobe Flash installed. That would be versions of Flash prior to 10.1 which added an auto-update feature that brings security patches and other goodies. If an older version of Flash is found, it's disabled, and the user is pointed to Adobe's site to get the latest.
As usual, the new build can be found in Software Update.
