- File Formats: When opening a PWB file containing a Model Filter that includes a Model Plane, the Model Plane was not always being linked to the Model Filter Condition. This has been fixed.
- Optimal Power Flow (OPF): Removed the field OPF_SolutionType on the object OPF_Options. This does not do anything.
- Transient Stability: When reading a switched shunt model from a DYR file, if the bus did not exist it would cause an error. This has been fixed and the model is properly skipped then.
- Transient Stability: Fixed bug with initializing the Pref-Controller WTGTRQ or WTTQA1 when the MVABase of the PrefController did not match the MVABase of the generator.
