This release adds a new feature: Physical meters can now be defined to run in both directions, similar to virtual meters. Activating this option on the meter definition page will disable the automatic meter change detection and will instead provide a check box on the reading entry page to manually indicate a meter change. This feature is important for people operating solar panels without a separate meter for the panel. The combined meter will run backwards when there is more energy produced than consumed.
Note that it is currently not supported for bidirectional meters to wrap around (from 0 to 999999…).
