     Changelog since 4.51.2 release to PyPI on 19-Oct-2021
 
+    4.51.2.1
+        New Window parameter!  grab_anywhere_using_control
+            Default is TRUE
+            Feels like a risky change to have default to True, but it also means no one changes their code and gets the feature
+            If enabled, you can use the control key + Left Mouse button to move your Window, just like Grab Anywhere.
+            Enables you to move windows that you can no longer reach the titlebar for
+            Let's see if anyone notices or complains
