Riffyn tracks changes to processes as versions. Major changes to a process (adding/removing steps or resources) will trigger the creation of a major version (e.g 18.05 to 19.00). Minor changes (renaming steps, adding properties or components) will result in a minor version (18.01 to 18.02) being created.
On selection of a step, a diamond icon will indicate the versions in which the selected step was modified. Additionally, creating an experiment in the working process version will automatically create a new version of the process if changes to the working version have been made.
