Aladdin Systems has released StuffIt Deluxe 6.0.1, an OS X-friendly version of its compression utility.

New features include additional support for GnuTar file decompression, maintaining file and user permissions for OS X users. It also offers symbolic-link support, preventing data-loss when stuffing and unstuffing applications, as well as improved Microsoft Entourage support. Entourage users can now automatically attach archives to outgoing Entourage email messages.

Improved anti-virus support also gives a choice of anti-virus applications upon "unstuffing."

The update is available as a free download to registered users of StuffIt Deluxe 6.0.
