Hamburg, Germany, November, 2005 – German software producer Gentleware AG has made an outstanding user experience the focus of the solid new features of the newest release, version 3.2, of Poseidon for UML.

Client input into the new functionality, including UML 2.0-compliant sequence diagrams, customizable documentation generation for Word 2003, and autolayout for class diagrams, has resulted in a superior product that increases productivity and exceeds the demands of the expanding market for Unified Modeling Language (UML) tools. These carefully constructed enhancements can be evaluated free of charge for 30 days or purchased at the Gentleware web site ( Among other products, commercial users may choose the Standard Edition for USD 249 or the Eclipse-integrated Professional Edition for USD 875. Gentleware also offers convenient and economical concurrent user license packages for multi-user environments.

The new version takes another giant step past competitor’s tools and proves yet again that Poseidon for UML belongs at the top of the field. The new sequence diagrams incorporate not only new UML 2.0 notations such as combined fragments to render loops, switch statements, etc., but also “inspections” that offer on-the-fly modeling critiques and advice to further boost development quality and speed. Class diagrams in the Professional Edition are quickly and efficiently organized and made more readable through an integrated autolayout function, which is especially useful during the reverse and roundtrip engineering processes. Once the model is ready to be shared, users now have the option of automatically generating custom documents into HTML in the familiar UMLdoc format (based on the JavaDoc format) or into Word 2003. “Gentleware has taken the approach of carefully studying the problem, then implementing the best solution possible, holding the needs of the users in the forefront,” relates Dr. Marko Boger, CEO of Gentleware AG. “The result is a tool that is a direct response to consumer demands.” This tack makes for a better user experience; each diagram type is worked on individually to make the best choices for that particular diagram, rather than to create a generic function and then derive sub-optimal variations of it to fit to the diagrams. The resulting product is the embodiment of the elegant transition to UML 2.0, continuing the Gentleware tradition of excellence.
