@ -28,6 +28,8 @@ will consitute of a breaking change warranting a new major release:
## Changed
- GPS Fix has changed event is no longer triggered for the EM
- MGM and SUS rates now will only be calculated, if 2 valid consecutive datapoints are available.
The stored value of the last timestep will now be reset, if no actual value is available.
