Features and Improvements
- General: Added ability for the Interchange MW and Mvar fields for an Area to be calculated from the area tie-line flow subscriptions.
- General: Ensuring MaxVarsInExpression is *always* 8, not 32 in Retriever as it was previously. This was breaking things and was inconsistent with files created in Simulator.
- General: Fixed bug that was causing an interface to always return 0 for the flow in real time mode
