  • Property "Filename" is not diffed by LemonTree.Fixed in 2.0.2
  • SaveFileDialog prompts twice when overriding a file (for example file dialog "Start Merge" and selecting an existing file). That does not happen on Windows builds prior to 10.0.17763. It seems to be a bug in .NET version.
  • The text of "Internal requirements" is cut off to 256 characters.
  • When changing the kind of an action from "RaiseException" to "Reduce" LemonTree writes "Opaque" in the merged model. There are 2 new kind of actions in EA 14 which LemonTree doesn't support.
