Merge Plugin was split into two - Merge Plugin and Merge Core Plugin. Merge Core Plugin provides project comparison-related functionality, and Merge Core Plugin provides merge functionality on top of the comparison.
Because of that, com.nomagic.magicdraw.merge.MergeUtil was split into com.nomagic.magicdraw.merge.MergeUtil and com.nomagic.magicdraw.merge.CompareUtil.
MergeUtil extends CompareUtil, so the old code is still compatible.
Other Open API changes
org.eclipse.core.runtime.IProgressMonitor and extended classes are removed. All usages are changed to com.nomagic.task.ProgressStatus.
JRuby scripting engine is removed. It is possible to add it to the application, but we highly recommend rewriting all existing scripts using any of the other supported scripting languages.
Note: there is no forward compatibility between 2022x version and previous versions. Projects saved with 2022x version will not open properly with previous versions.
