This release bring many fixes and new features in the editor. For example:
- Save On Close is implemented. Now if the user has modified some Definition Files and has not saved them on the file system, a dialog appear when closing the application, asking if the user wants to save the still unsaved Definition Files
- Now undo/redo is supported

Also now the maps implement Item selection (also sent to the User Application).

The OpenGL integration has also been improved
