Apple updated Mac OS X “Lion” to version 10.7.3 on Wednesday, an update that includes several bug fixes and changes to Lion’s Directory Services. The update also includes Safari 5.1.3, which itself includes bug fixes—the Safari update apparently requires Mac OS X 10.7.3, as it is not being offered as a separate download.

The patch notes for the update:
