It seems like Adobe is releasing an update a day this week. Today brings a small tweak to the output module of Bridge CS4. The Output Module in Bridge CS4 provides PDF and web gallery creation capabilities from  inside Bridge CS4.

This update provides the ability to add header and footer information to PDF files and reduces the size of JPEG files generated for use in web galleries. 

The header / footer info is great. For example, it lets you add a copyright to the bottom of each page. Keep up the great work Adobe.
