 # Arduino Library for the ESP32 CAN Bus (ESP32-Arduino-CAN)
 
+## V2.0
+This is a rewrite of the original library created by [miwagner](https://github.com/miwagner/ESP32-Arduino-CAN). The old version of this library used registry commands to configure the TWAI[^1] peripheral. Newer versions of the Espressif IDF have built in functions to configure the TWAI peripheral that are more reliable. V2.0 of this library incorporates these new IDF functions in the original function calls of the ESP32-Arduino-CAN library.

 ## Features
-
-* Support the CAN Bus from the ESP32 (SJA1000)
-* CAN Messages send and receive 
-* Various Bus speeds
-* Standard and Extended Frames
-* CAN Message Filter
