Release 2.2 of pure::variants, an Eclipse integrated software variant management suite has been released today. This release provides support for expressing modeling constraints and a new, simplified language for restrictions and constraints including graphical and textual editors with syntax highlighting and automatic completion. Extended consistency checks for models including support for user-defined checks help users to create and maintain high quality models. For instance type model violations can be checked online during model manipulation or offline as part of the model review process. Domain specific rules can be integrated easily. The improved model evaluation provides better conflict resolution and user interaction, leading to faster variant configuration. Read more about the release here. A free 30-day evaluation version of the Developer Edition is available here. Or get the free Community Edition (for non-commercial use only).
