+## New in v0.10.0:
+- Added encoder acceleration in servo tester mode. Makes the operation very handy. If you want to make bigger servo movements, just rotate the encoder faster!
+- Unstable Multiswitch issues because of incompatible espressif 32 board solved, see comments in src.ino
+
 ## New in v0.9.0:
 - Servo is able to oscillate way faster in automatic mode, speed adjustability improved
 - Made sure, there is no language string array pointer overflow, if EEPROM was deleted before
-- There are still issues with unstable Multiswitch readings. Solution for now: use the pre compiled bin files or use Arduino IDE 2.0.3 with espressif board 2.0.5 (which is unfortunately incompatible with VS Code)

 ## New in v0.8.0:
 - Support for calibrated analogRead, using the ESP32AnalogRead library is improving battery monitoring

 unfortunately it is not compatible with VS Code, so you have to use Arduino for now. The pre compiled .bin images were made with Arduino.
