 * Seventh version. Changed Double to Float in the MMSyn7l 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.

+## 0.8.0.0 -- 2020-08-16
+
+* Eighth version. Changed the dependency of mmsyn7ukr bounds.
