Revision management of design data using third-party version control systems is a foundation element of Altium Designer's support for Design Team collaboration.
Altium Designer Winter 09 includes a number of enhancements in this area.

Version number in Schematic documents

The schematic documents themselves can display their revision number as extracted from the VCS database. Simply place a special string =VersionControl_RevNumber, and the document revision number will be displayed. This is particularly useful at output generation time

Additionally, if such a special string is placed in a schematic component, the version number of the library file which is matched to this component while it is included in a design can also be displayed in place in the schematic document.

New Storage Manager file history panel

The Storage Manager file history panel has been simplified by combining both the local history view and the VCS revision history view into one single file history time line. To switch between the classic view and the combined view, right click on the bottom pane and choose either Switch to classic view or Switch to combined view.
The combined view also indicates when releases that included the current file took place.
