[Kde-games-devel] KSudoku new engine

A Dilluns, 16 de novembre de 2009, Johannes Bergmeier va escriure:

Good you are working on new features, but KSudoku has a nasty crasher[1] that 
should be fixed first imho. I know working on bugs is not as cool as doing 
features but users need it more than a new engine.
