http://argouml.tigris.org/issues/show_bug.cgi?id=6090 This makes swimlanes in diagrams unusable. Existing users diagrams with swimlanes can't have new transitions added. (we have had two reports of this in a short time)
http://argouml.tigris.org/issues/show_bug.cgi?id=6086 This means activity diagrams can't be used for AndroMDA users in the way described in their tutorial (part of which I thing we wrote).

This release introduces a new implementation of property panels. Property panels are now coded in XML files. (These XML files are included in the released archives.)
This release integrates the results of the GSoC projects. A new sequence diagram implementation (also a GSoC result) is provided. Additionally, further functionality is moved into separate modules.
This release introduces UML profile support. Custom profiles can be created and used. This offers a convenient solution for other projects that rely on profiles, like AndroMDA (andromda.org) and ArchGenXML (plone.org)
