Release Notes

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

Build 256 -- January 20, 2012

  • The default installation now includes support for executing SPARQL queries from the user interface. Enable the "SPARQL Query Tab" from Window | Tabs, or the "SPARQL Query" view from Window | Views | Ontology views.
  • Made some improvements to the "Ontology annotations" view to more clearly indicate language and type information. Also fixed a problem that caused text overlap.
  • Bundling an updated version of the Apache Felix Framework (version 4.0.1). Previous versions were problematic for Java 7 users. Please note that we don't officially support Java 7 yet.
  • Fixed a problem with the installer that was preventing users from being able to perform silent uninstalls.

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 YouTube video for an overview of OWL Diff usage.
  • 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).
