.Modelica_LinearSystems2.UsersGuide.ReleaseNotes.Version_2_4_1

Information

This version requires the Modelica 4.0.0 Library. It is backward compatible to the previous version 2.4.0.

Improvements in this version

• Utilize ModelicaIO functions for matrix I/O, see issue #34. Concerning functions are marked obsolete, see below.
• Use functions from DymolaCommands library instead of Dymola's build-in functions, see issue #66.
• Disable an assert causing function crash in Utilities.Import.rootLocusOfModel, see issue #130.
• Over 20 issues (including pull requests) have been addressed for this release.

Improvements in build.2 (2021-11-16)

• Bug fix: Remove buggy initialization of matrix ABCD in DiscreteStateSpace2.
