The Modelica Buildings Library 11.0.0, 10.1.0 and 9.1.2 were released on
April 9, 2024.

The Modelica Buildings Library 11.0.0 is a major release. Version 10.1.0 is
a minor release with new models, version 9.1.2 is a maintenance release,
and both are backward compatible with 10.0.0 and 9.1.1, respectively. All
three versions contain various model improvements and versions 10.1.0 and
11.0.0 also include new models.

BuildingsPy 5.1.0 adds support for updating Continuous Integration test
specifications for OpenModelica and Optimica, and it contains bug fixes.
The following major changes have been done for the Modelica Buildings
Library 11.0.0:

- A package for central plants with reversible air-to-water heat pumps
has been added to Buildings.Templates.Plants.HeatPumps
.
The package allows configuration of the type of hydronic integration.
- The models for 1st to 5th generation district heating and cooling
systems have been expanded and revised, a user guide has been added, and
the models have been moved from the package Buildings.Experimental.DHC
to Buildings.DHC

.
- A package for domestic hot water generation and loads that are served
by a district system has been added to Buildings.DHC.Loads.HotWater

.
- The initialization of the Spawn model has been refactored to avoid an
iteration between Modelica and EnergyPlus as this caused numerical problems
for some model configurations.
- The implementation of the blocks for the Control Description Language (
CDL
),
which is being standardized through ASHRAE Standard 231P, has been revised
to comply with the latest draft of the standard.
- A tutorial for how to build a simple system model has been added to
Buildings.Examples.Tutorial.SimpleHouse

.
