+OpenModelica is the only actively maintained complete open-source Modelica-based cyber-physical mathematical modeling, 
+simulation and optimization environment intended for industrial and academic usage. 
+Its long-term development is supported by a non-profit organization–the Open Source Modelica Consortium [OSMC](https://www.openmodelica.org/)
+with many company, institute, and university members.

+OpenModelica 1.16.2 has been released. This is a bug fix release to the recently released OpenModelica 1.16.0, primarily to improve the stability of the OMEdit GUI. The main enhancement in the 1.16.0 release, see [release notes](https://trac.openmodelica.org/OpenModelica/wiki/ReleaseNotes/1.16.0) is the graphical user interface support of replaceable items in libraries. The new frontend has been further improved with enhanced support of records and arrays. The new front-end can now handle 100% of the Modelica Standard Library 3.2.3 models. Also improvements to backend and simulation run-time regarding homotopy, CVODE solver included, new minimal tearing, better support for models with records, enhanced OpenModelica debugger that can show direct variable dependencies, a full-fledged Modelica package manager is included, initially available via the command line interface, and more.
+
+Further improved FMI support in OpenModelica OMSimulator: GUI: text editing of SSP models, undo/redo functionality, delete components, etc. FMI/CoSimulation 2.0 now includes CVODE solvers and customization via simulation flags. SSP 1.0 is supported. See www.openmodelica.org for download.

+
+The equation model debugger in the recent OpenModelica 1.16.0 release and in the 1.16.2 bugfix release is enhanced with new functionality to help the user understand sources of model errors.
+

+
+The figure shows the debugger tracing how variables or equations influence a variable.\
+Left: Turn on the menu choice. Right: List of variables directly influencing the chosen variable.
+
+The new functionality allows the user to perform a “backward” trace of which variables or equations that directly influence a chosen variable (see figure). This can be useful to understand the dependencies causing a faulty variable value.
