+  V2.2    01.11.20     Virtual weights built in
+  V2.12   07.10.20     bug fixed: LR value was displayed in the wrong display position
+                       Voltage for specified battery types deleted
   V2.11   18.08.20     code is now compatible with standard OLED displays
                        and original code base (default pw length = 32)
   V2.1    18.07.20     added support for ESP8266 based Wifi Kit 8
