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)
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.
