IMPORTANT: If you have not yet looked at the enhancements of previous versions 4..x, please visit these video overviews of version 4.0.0 and version 4.1.0.

This feature is still in beta.

jUCMNav's improved stub binding dialog now contains 2 tabs, one to bind start/end points to input/output segments, and the other to handle component bindings and responsibility bindings .

jUCMNav can now import/export URN models in the standard XML format specified in ITU-T Z.151:

See Z151ImportExport for the project's documentation and instructions. See also Yan Gao's Project Report

An algorithm for formula-based contributions to indicators (to represent external drivers and compute indicator values other than satisfaction levels, e.g., money, number of items, time, etc.). These are shown in blue over the indicators. Contributions between indicators are given names that can be used in formulas attached as metadata to target indicators. This feature is still in beta.

Also:

• Support for XOR decomposition in all algorithms
• Support for Legal Compliance profile in all algorithms

In the general preference, it is now possible to select whether UCM/GRL diagrams should be anti-aliased . Anti-aliasing is good when diagrams are displayed on screen, but not so much for printed documents. It is also possible now to display/hide the symbol used on elements and links to indicate the presence of metadata.

• 1 additional OCL metrics (UCM path node coverage)
• 38 additional OCL semantic rules, with updated OCL library
  • 20 rules for Legal model compliance (new group, for Legal profile)
  • 8 rules for Z.151 export and 5 more for jUCMNav deprecated elements (new group)
  • 2 rules for GRL consistency/completeness, 2 for UCM consistency/completeness, and 1 for unused element (UCM path nodes not covered by scenario definition, for test coverage)

• Metamodel changes: Added support for Aspect-oriented UCM constructs, UCM failures, responsibility bindings, Z.151 concerns, and UCM time units

• Reports generated, MSC Viewer, and user documentation only available in English.
• User documentation not up to date.
• Changing the visibility of several UCM/GRL elements via jUCMNav's main preference page may require you to reload the model or refresh the diagrams with the Scenario and Strategy view.
• The UCM traversal mechanism does not take into consideration advanced stubs, failures, and some other attributes.
• Generated reports could be more complete
• The UCEd import will not work with the latest version of UCEd.
• There are no extension points to give your own scenario/strategy algorithms and no UI to choose them.
