Information

Version 4.2.0 is backward compatible to version 4.1.0. This means, there is no need to convert user models, because no renaming or moving has been done on the library.

Short overview:

• xx new components (e.g. Blocks for recording of min and max of a signal)
• xx improved components (e.g. tables can now read CSV)
• xx potentially non-backwards-compatible changes (especially Constants.inf, Constants.small, Constants.eps)
• xx bug fixes, which may cause the simulation results to change for the better
• xx models marked as obsolete
• This version is based on the recent Modelica language standard version 3.6.
• About [Link to resolved] issues xxx issues (including xxx pull requests) have been addressed for this release.

The following libraries, that were previously using version Modelica 4.0.0, were tested successfully with version 4.1.0 without any modification, using Dymola 2025x Refresh 1 and/or OpenModelica 1.25.0 (alphabetical list):

The following new components have been added to existing libraries:

The following existing components have been improved in a backward compatible way:

The following existing components have been changed in a non-backward compatible way, even though this is not expected in general to affect models using the library, except in very rare cases:

The following critical errors have been fixed (i.e., errors that can lead to wrong simulation results):

The following models were declared as obsolete, thus to be preferably replaced with better, more general ones:
