As with previous releases, JaCoP focuses on ease of use, efficiency, and modeling power by providing more and more global constraints.

In JaCoP 2.3 you'll notice:

• Number of new global constraints implemented, namely Among, GCC, Regular, two new variants of ExtensionalSupport constraint (STR, MDD), Stretch, and Sequence constraints. 

• Redesigned search functionality making it possible to express search as by designing search plugins and transforming available search. 

• Redesigned part of the JaCoP core focusing on domains, making it easier to add new domains representations.
• Significantly improved Java Doc API making code even better documented.
• Number of new examples explaining how to apply CP technology.
