In the process of implementing the new optimization controller, a number of slots were added or modified. The new slots are visible when using the existing controller but should not affect model behavior. In addition, the number of columns of some LP Parameter slots were modified to make them consistent. This could affect DMIs. Finally, the Hydro Generation slot on the Thermal Object was previously being set to zero at the end of the run if not valid. This no longer occurs in this release.
