Enhancements / Fixes since 2.4.1
Key Performance Indicator (KPI) modelling and monitoring support.
Strong improvements to generated MSC validity and robustness.
Enhancements to the MSC visualization engine. MSCs now more compact.
Fixed issue with MSC export not working depending on new jUCM file wizard
Various minor UI-related issues.
Export diagrams to PNG (finally!)
Prototype integration between GRL strategies and UCM scenarios
Upgraded the French version of jUCMNav.
Known Issues in 3.0.0
Autolayout still a prototype
User documentation not translated yet.
User documentation only partially reflects integration of GRL and scenarios.
There are no extension points to give your own scenario/strategy algorithms and no UI to choose them.
Visibility of GRL contribution icons and text now can be set via jUCMNav's main preference page, but open editors are not automatically updated. You need to reload the model.
Memory leak. With very large diagrams (30+ complex maps), you might only be able to open it half a dozen times before you run out of memory. Restart Eclipse to clean memory or increase JVM heap space until we find the memory leak source.
