 #### Release notes
 
 Version 1.2.0 adds gain scheduling to analog P and PI controllers and fixes some Modelica language issues.
 
+Version 2.0.0 is the same as 1.2.0 but it works with MSL 4.0.0. Technically speaking it is not backwards compatible with 1.2.0 because it depends on the non-backwards compatible MSL 4.0.0, but in practice the conversion script only affects the examples and applications in the library, but it doesn't change the code of the used blocks in the library.
