Checkstyle activated on all distinct plug-ins.

Eclemma used on a regular basis to ensure and improve code coverage from the unit tests.

Yourkit java Profiler used on a regular basis to improved performances and avoid bottlenecks.

Findbugs launched on a regular basis to avoid detectable bugs.

Javadoc represents about 40% of the java source code.

An analysis of the code base is available on Open Hub.

End of Life: 

There are no outstanding issues with the API state of this release. All mehods and classes that face deletion have been marked as deprecated with instructions on how to switch to the new behavior, and will stay in the code base until the next release.


No standard exists concerning the model comparison, though EMF Compare works nicely with any standard-based metamodel.

Since the 1.2 release a specific support for the UML standard is included in EMF Compare. This is also included in the 3.* stream.
