Comparing a statechart to its local history Copy link to clipboard

Whenever a statechart is saved to its statechart file, the previous version of the file is saved to the local history.

Warning: The local history typically contains a few recent versions of a file. However, you should never rely on anything being available in the local history at all. It is definitely no replacement for a data backup or a version control system

To compare a statechart to an older version in the local history, proceed as follows:

1. In the project view, right-click on a statechart model file. The context menu opens.
2. In the context menu, select Compare With → Local History….
3. In the local history, double-click on the file’s version to compare to.
4. The comparison results are shown.
