New and Noteworthy - VIATRA 0.8.0

New state coder. Previously VIATRA-DSE 0.7 had a slow and sometimes buggy state coder (which is needed for identifying recurring state in the search space) but at least worked for any problem domain. In 0.8 a new state coder is introduced which is much more simple and therefore faster but. It simply encodes 1) all the attribute values and 2) all the attribute values of the referenced EObjects of all the EObjects. The disadvantage of the new state coder is that it may fail in certain scenarios (e.g., if a rule can add "A"s, another can delete "A"s and a third one can make references between them). From 0.8 this is the default state coder. When used, the metamodel (EPackage) of the domain must be defined for the DSE framework. VIATRA/DSE/UserGuide/API#State_coding

-* [[VIATRA/Transformation_API/MWE2_Integration]]
+* Added a class library that allows the definition of heterogeneous model transformation chains using a specialized description language.
+** Used base language is the Xtext MWE2
+** Sequence of model transformation steps can be easily specified and maintained.
+** Nontrivial side-effect relations between transformation steps can be handled.
+** The execution of event-driven transformations can be explicitly controlled.
+** Because of the specialized language, the description code base is short and easily expandable.
