CircuitPython 6.0.0 Beta 0 released! [Copy link]

 

From: https://blog.adafruit.com/2020/09/21/circuitpython-6-0-0-beta-0-released/

The first beta release of CircuitPython 6.0.0. It is relatively stable. The most notable additions since 5.3.x are basic low-power support when time.sleep(), initial ESP32-S2 support (including WiFi), and HCI support for the ESP32 coprocessor with _bleio. The low-power work changes timings and may introduce bugs. If you need a stable version of CircuitPython, use 5.3.x.

Installation Install
by following the instructions in the new Welcome to CircuitPython ! guide. To install the latest libraries, see this page in that guide .

Try the latest version of the Mu editor to create and edit CircuitPython programs and easily access the CircuitPython serial connection (REPL).

Port Status
CircuitPython has many "ported" versions that are core implementations for various microcontroller families. The stability of each port varies. As of this release, atmel-samd, nrf, and stm for the F4 family are stable. cxd56, esp32s2, and stm for other chip families are being actively improved but may be missing features and have bugs. mimxrt10xx is in Alpha status and may have bugs and missing features.
