Correction: At first I thought that Fortress was a replacement for Dragnet - not the case, SourceGear will continue to support Dragnet users, but new development has been stopped on Dragnet. 

SourceGear Fortress 1.0 is the debut version of their new application lifecycle management (ALM) solution.

• Version control (built from the same source tree as Vault 4.0)
• Work item tracking (from Dragnet, with significant new improvements).
• Excellent integration with Visual Studio 2005 and Eclipse.
• Easy to install. Designed specifically for small and medium-sized teams.

Changes from Vault 4.0:

• Visual Studio 2005 Item Tracking Client. Users can add/edit work items as well as query and run saved queries inside Visual Studio 2005.

• Eclipse Item Tracking Client. Users can add/edit work items as well as query and run saved queries inside Visual Studio 2005.

• Work Item Tracking Web Client. Users can browse and query bugs though a web interface.

• Web-Only users. Special licensing is available to allow for users who can only access Fortress through a web browser.

Changes from Dragnet:

• Users with the IDE clients can save commonly used queries, and easily rerun them or run a saved query with small changes without saving a new query.

• The Project Access rights were changed to make it easier for administrators to determine what the effective rights for a user are.
