In the first releases, KS-ProjectPlanner was published as a freeware. There have been many downloads and user requests for more features. Many of the requested features are now realized in the Pro Version.
The program has also become much more powerful. Where the freeware version could handle hundreds of tasks fluently, the Pro version can do it with thousands. This was achieved by many optimizations and the implementation of sophisticated data structures. Some core calculations have been speeded up by the factor of one hundred.
ProjectPlanner Pro has it's own website !
