This is the third Alpha release of CircuitPython 6.0.0. It is relatively stable. This release is still an Alpha release as some API changes and additions are not yet included. ESP32-S2 Wifi support and HCI support for the _bleioESP32 coprocessor will be coming in a future release but are not yet included.

On ESP32-S2, the WS2812 can be driven when powered on, but it cannot be controlled programmatically yet.

It seems that D University is now promoting circuitpython? Is mpy not developing actively now?

CircuitPython focuses on education and maker, and its usage is quite different from MicroPython. MicroPython is developing well.
