 # GPIO CONTROL
 
+> [!IMPORTANT]
+> Since v2.9.0 the original `RPi.GPIO` library was replaced with `rpi-lgpio` to support the GPIO access in newer OS versions (>= kernel 6.6).
+> This new library is api compliant to the old one, but behaves differently in some aspects (see [rpi-lgpio differences](https://rpi-lgpio.readthedocs.io/en/latest/differences.html)).
+> Especially the `Debounce` difference changes the behavior of the `bouncetime` property! The actions are not triggered immediately anymore, but after the signal has been stable for the specified time, causing a delay. This also has impact to the usage of `hold_time` and `antibouncehack`!
