- getSignalNames(...; getVar=true, getPar=true, getMap=true): New keyword arguments to filter names.
- writeSignalTable(instantiatedModel,..): Include attributes = Map(model=..., experiment=...).
- Some internal bug-fixes.

+- Requires SignalTables 0.4.0 (introduces Map-signal)
+- getSignalNames(...; getVar=true, getPar=true, getMap=true): New keyword arguments to filter names.
+- writeSignalTable(instantiatedModel,..): Include attributes = Map(model=..., experiment=...).
+- Some internal bug-fixes.

 ### Version 0.9.2
 
 - Bug fix: integrator IDA() can be used (especially to avoid solving large linear equation systems in the model).\
   Extend some test models to use IDA().
-  
+
 
 ### Version 0.9.1
 
 - Requires SignalTables 0.3.5.
 
 - [`@usingModiaPlot`](@ref): corrected and fixed in docu. Alternatively, @usingPlotPackage can be used,
   provided package SignalTables is present in your current environment.
-  
+
 - Internal: A function call in the generated code prefixed with `Modia.`.
