- File Formats: An access violation could occur when reading in the IEEE Common Format due to transformers not having regulated buses defined. This has been fixed by no longer allowing tranformers to be on control if they do not have a regulated bus defined.
- Transient Stability: Fixed failure of network boundary equation solution when a DC line terminal has been de-energized due to line switching on the AC system. Previously, this would result in the transient stability aborting. It will now properly model the outage of the converter.
