 > This version includes (requires?) the [ESP32Servo](https://www.arduino.cc/reference/en/libraries/esp32servo/) library to get the analogWrite() and tone() functioning correctly. If you don't have it installed uLisp will compile but you won't have analogWrite() and tone().
 
 New features, some care in editing required:
-* Lisp `:keywords` that auto-quote themselves
 * Ability to add multiple (more than one) extension tables (using `calloc()`) *may not be portable to other platforms*
 * Nonlocal exit: `(throw)` and `(catch)` (\*)
 * Templating: backquote/unquote/unquote-splicing (\*)
