The Modelica Buildings Library 12.1.0 has been released today.

Version 12.1.0 is backward compatible with 12.0.0.

The library has been tested with Dymola 2025x, OpenModelica 1.24.0, OPTIMICA 1.55.11 and recent versions of Impact.

This backward compatible version adds a new package with an autotuning PID controller.

Also, many models have been updated to improve performance, to ensure compliance with the Modelica Language Standard and to correct model errors.
