 ## Release Notes
 
+### Version 0.3.8
+
+- Better handling if some input arguments are `nothing`.
+- Bug corrected when accessing a vector element, such as `mvec[2]`.
+- Documentation slightly improved.
+
+
+### Version 0.3.7
+
+- Replaced Point2f0 by Makie_Point2f that needs to be defined according to the newest Makie version.
+
+
+### Version 0.3.6
+
+- Adapt to MonteCarloMeasurements, version >= 1.0 (e.g. pmean(..) instead of mean(..))
+- Remove test_71_Tables_Rotational_First.jl from runtests.jl, because "using CSV" 
+  (in order that CSV.jl does not have to be added to the Project.toml file)
+
+
+### Version 0.3.5
