The Modelica Buildings library 5.1.0 has been released on June 14, 2018.

Version 5.1.0 adds new libraries, new components and improves various existing components. Version 5.1.0 updates the license to a 3-clause BSD license. It is backward compatible with versions 5.0.0 and 5.0.1.

This release adds a model for propylene glycol - water mixtures, a model for long pipes suited for district heating and cooling simulations, a new valve model whose opening characteristics can be fit to measured data, and idealized models that allow to prescribe the temperature and humidity in any part of a fluid flow system.

All models simulate with Dymola 2018FD01 and JModelica (revision 11291).
