Roadmap
Mid-2022 scheduled release.
Bugfix release for 1.17.0. Scrapped in favour of 1.18.0
Bugfix release for 1.18.0
The main goal of release 2.0.0 is to provide uncompromised performance for end users. This means in particular:
- 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.

This release will further consolidate the quality of the tool after the 2.0.0 release, by addressing remaining long-standing issues and adding new features.
This milestone collects issues that do not have a definite target release version (yet).
These are tickets which need more external input in order to decide on further actions/progress.
Use this milestone for tickets that are invalid, duplicates or wontfix.
