Release 2026.10.23.15

Improvements to cooling-unit supply control

Each cooling unit’s supply air temperature is adjusted step by step as the solve runs. We fixed an issue where a model in which every cooling unit is set by temperature difference could stop when the solve started. Those models now run. Models with at least one cooling unit set by cooling capacity run exactly as they did on the release before.
