Adafruit has this month announced the availability of its CircuitPython 6.0.0 alpha.3 release, providing a “relatively stable” although some API changes and additions are not yet included. In future releases but not yet included are ESP32-S2 Wifi support, and _bleio HCI support for ESP32 co-processors. Downloads are available from circuitpython.org.
“The most notable additions since 5.3.x are basic lower power support when in time.sleep() and initial ESP32-S2 support. The lower power work changed time keeping and may have introduced bugs. Please use 5.3.x if you need a stable version of CircuitPython.”
New features and improvements since 6.0.0 Alpha 2 :
