Valhalla is progress has been placed on hold until a full unit testing framework has been implemented for the existing classes.
Once in place, the testing framework will allow users to easily and effectively test the stability of Valhalla on their own system.
The framework will also have the capability for individual test cases to be provided with each plug-in class, allowing third party developers to utilise the test suite also.
Development is about 30% complete and will be based upon SimpleTest (http://simpletest.org/).
Stay tuned for more info!
