 * Sixth version revised B. Switched to the newer version of dependencies so that the library can be 
 successfully compiled with GHC-9.6.2 compiler.
 
+## 0.7.0.0 -- 2023-07-30
+
+* Seventh version. Added asynchronous concurrent calculations and async as a package dependency. Added
+  the possibility to calculate for the text with maximum 9 words or their combinations (using +x
+command line option). Added new draft papers with improved theory about the usage of the software.
