HP announced by the end of December 2010 a new basic version of the agile accelerator 4.0. There is now a version for QC 10 and a version for QC11/ALM available. New support is included for unit testing. Development tasks can be tied to unit test cases (NUnit, JUnit, or FitNesse). Continuous integration tools like Cruise Control/Hudson can be called from within QC to start the build process. Agile reporting is streamlined. There is also a new team-based Sprint burndown chart that shows a burndown comparison across teams.
The basic module can be freely downloaded from this link.
