CircuitPython 9.2.4 Released!

<

From the GitHub release page:

This is CircuitPython 9.2.4, the latest bugfix revision of CircuitPython, and is a new stable release.

WARNING for nRF52 boards only: If your board has an nRF52 UF2 bootloader whose version is before 0.6.1, you will not be able to load CircuitPython 8.2.0 and later, due to increased size of the firmware. See these instructions for updating your bootloader.

Highlights of this release

  • Update frozen modules, including a fix for adafruit_requests.
  • audiofilters: add Distortion and implement LFO ticking.
  • Add canio support for i.MX boards.
  • Fix RP2 picodvi crash.
  • Fix STM USB crashes.

Incompatibility warnings

Download from circuitpython.org

Firmware downloads are available from the downloads page on circuitpython.org. The site makes it easy to select the correct file and language for your board.

Installation

To install follow the instructions in the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.

Try code.circuitpython.org or the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).

Documentation

Documentation is available in readthedocs.io.

Port status

CircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable (but see Known Issues below):

  • atmel-samd: Microchip SAMD21, SAMx5x
  • cxd56: Sony Spresense
  • espressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6
  • nordic: Nordic nRF52840, nRF52833
  • raspberrypi: Raspberry Pi RP2040, RP2350
  • stm: ST STM32F4 chip family

These ports are considered alpha and will have bugs and missing functionality:

  • analog: Analog Devices MAX32690
  • broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
  • espressif: ESP32-P4
  • litex: fomu
  • mimxrt10xx: NXP i.MX RT10xxx
  • renode: hardware simulator
  • silabs: Silicon Labs MG24 family
  • stm: ST non-STM32F4 chip families
