Get your Software Update system preference warmed up because Apple released Mac OS X 10.7.3 on Wednesday evening. The update is recommended for all Lion users.

The update fixes problems with smart cards used to log on to OS X; authentication with directory services; address compatibility issues with Windows file sharing; and improvements to stability, compatibility and security.

Language support has also been added for Catalan, Croatian, Greek, Hebrew, Romanian, Slovak, Thai, and Ukrainian.
