- File Formats: Fixed access violation when reading contingency records from an Areva EMS file.
- Oneline Diagrams: Fixed an access violation that would occur when closing a oneline for which a Display Explorer is also open.
- Optimal Power Flow (OPF): In OPF solution when using the minimum control change option, the phase shifters and DC Lines controls were not working properly and instead were using a cost function centered around zero instead of the present operating point. This has been fixed.
- Transient Stability: Fixed treatment of damping on the WTGT_A model.
- Transient Stability: When reading a DYR file which contains the USRMDL with the name DERAU1, Simulator will automatically convert that to the DER_A model.
- User Interface Dialogs: When trying to change the ID of a branch from the branch dialog while in Edit mode, an error for "Cannot make a visible window modal" could result. This has been fixed.
