 * Sixth version revised H. Changed the bounds for dependencies so that now also GHC 8.10* series are supported.
 
+## 0.7.0.0 -- 2020-06-24
+
+* Seventh version. Changed Double to Float in the MMSyn7s module so that the functons can be consistent with new dobutokO packages. Besides, the double precision 
+is not needed and in some cases is meaningless and can potentially (a little bit, however) reduce performance in some cases. Some minor code and documentation improvements.
