Roadmap

achieving full coverage of Modelica Standard library 3.2.3 and 4.0.0, including conversion scripts
achieving full or nearly full coverage of open source Modelica libraries
providing full support of replaceable classes and models from the OMEdit GUI
provide full-fledged duplicate feature in OMEdit
providing much faster response of the OMEdit GUI
allowing to inspect and modify parameters and replaceable classes and models in hierarchically built system model

The main enabler of release 2.0.0 will be the new front-end, which has been under active development since 2016, and is nearly complete. You can check the coverage status of the Modelica Standard Library 3.2.3 and follow the coverage history over time in the figure below. As you can see, the frontend coverage of MSL has already reached 100%. The coverage of many other open-source libraries is available from this page.
