Due to changes in the Dezyne runtime you have to replace the old Dezyne runtime in your projects with the new one.

Known issues

  • When using dzn service version higher than 2.7.0 there are cases when no state charts and table views are generated. In the Console you will typically see an error message with a line 'No applicable method for # generic type…​'

  • The following (language) features are not yet available for verification: blocking, external and async.

  • In some corner cases, nested function calls will cause a failing verification.

  • For verification, even though service version 2.7.0 or 2.7.1 is selected/specified, service version 2.7.2 is used instead.

  • The verification feature has been discontinued for all older releases.

  • Not all old(er) versions of the Dezyne Eclipse GUI/plugin notify you that a new version is available. Please empty the 'dezyne_folder/p2/org.eclipse.equinox.p2.repository/cache' folder and restart Dezyne, or simply download the new version and use it with your (old) workspace.

  • Views (i.e. system views, state charts, state and event tables) are not cleared if they can not be updated due to an error in the model or due to missing data
