-# Nerd_STF v2.1.0
+# Nerd_STF v2.1.1
 
-This update adds some operations from calculus, as well as many new geometry structures.
+This update doesn't add any new features, simply a code simplification, using some of the .net 6 tools, such as global usings and file-scoped namespace declarations.
 
 ```
