- Integrated Topology Processing (ITP): When performing the Equivalencing on a full-topology power system model, some errors could occur in the calculation of the equivalent due to numerical precision problems. This has been fixed.
- Integrated Topology Processing (ITP): In the integrated topology processing, fixed an error that could cause a power flow mismatch in a very rare situation. A dead bus that was radially connected and had a NomG or NomB value but did NOT have any load, gen, or shunt attached would cause the problem.
- Transient Stability: Fixed initialization of REPC_A and REPC_B when the Ki or Kig values are entered as exactly zero.
