 different modules: DobutokO.Sound.Overtones, DobutokO.Sound.Uniq and DobutokO.Sound.Octaves. This was done to simplify compilation and to produce more 
 logical and semantic structure. The most complicated functions from DobutokO.Sound.Functional module are moved to a new package dobutokO3. Some code 
 improvements.
+
+## 0.42.0.0 -- 2020-06-24
+
+* Fourty-second version. Changed Double to Float in the modules where possible to reduce redundancy and to open access to new possibilities. The shift is inspired 
+by: https://www.youtube.com/watch?v=FYTZkE5BZ-0
+Some minor code and documentation improvements.
