The Apache Foundation announced Tuesday that the software development and project management framework Bloodhound is now an official top-level project, having graduated from the organization's product incubator. Bloodhound is a highly flexible, open-source tool for collaborating on software development projects. Essentially a fork of the widely used Trac (a Web front-end for several popular versioning systems including Subversion and Git), Bloodhound adds multiple project hosting and an improved user interface, the foundation said.
