We are pleased to announce Protege 4.2 alpha!  The main thrust of the alpha series will be the roll out of several new plug-ins, including an ontology difference tool, enhanced explanation support, client-server capabilities, support for code generation, and a database back-end.  Please contact us via the [http://mailman.stanford.edu/mailman/listinfo/p4-feedback Protege 4 mailing list] with feedback and bug reports.


== Release Notes ==

The contents of the release notes section describe changes relative to Protege 4.1.

=== Build 249 -- October 4, 2011 ===

* Bundling initial release of OWL Diff; a new plug-in to calculate the differences between two versions of an ontology.  OWL Diff is loosely based on the PROMPT plug-in for Protege 3.x.  Please refer to Tim Redmond's [http://www.youtube.com/watch?v=JzMNDfy4jcg YouTube video] for an overview of OWL Diff usage.

* Bundling a new version of the HermiT OWL Reasoner (1.3.5).

* Fixed a bug that prevented the datatype panel on the Entities tab from getting refreshed properly.

* Fixed a problem involving the selection of classes and individuals.

* Fixed a problem with selection after an annotation property is refactored (thanks go to András Förhécz for contributing the fix).
