- Difference Case Tool: The following changes were described in the May 14, 2018 patch description. Instead of using the specified AUX Export Format Description to determine the object types written for NEW objects, the built-in "Network Model" was used incorrectly for both the object types and the fields resulting in the user-defined export format description being completely ignored. This has been fixed so that the following description is now correct.
- Difference Case Tool: When specifying your own AUX Export Format Description for use when exporting the changes between two cases using the Present Topological Differences Tool, we have modified how the NEW objects are written. The object types that are written will be determined by the specified AUX Export Format Description, but the fields that are written will be determined by the built-in "Network Model" format. This ensures that the list of required fields are included with New Objects.
- Transient Stability: Fixed an error that could occur resulting in a failed network solution when performing a fault very near the terminals of a multi-terminal DC line
