 A new optimization wizard has been added to PlanWise. You can find it in the ''Optimization Model''-tab by either selecting ''New model'' or choosing it directly from ''Model Wizard''. Together with the optimization wizard we have also added an area where you can view your created models and manage them directly.
-The optimization wizard enables users to quickly construct an optimization model by choosing decision variable, optimization target (objective function), and constraints, directly from a dialog.

The choices for each category is limited to a few, pre-defined choices to make it as user-friendly as possible.

 ==Support for CLP/CBC==
-Support for the open source solver CLP/CBC has been added. While it is significantly slower than some of the commercial solvers (how much depends on problem type and formulation) the performance of CBC in Heureka is many times that of LpSolve, and can for many users be a good alternative to commercial solvers.
