From the GitHub launch web page:
That is CircuitPython 9.1.0-beta.0, a beta for CircuitPython 9.1.0, and is a brand new unstable launch. This launch has identified bugs that will probably be addressed earlier than 9.1.0 closing.
WARNING for nRF52 boards solely: In case your board has an nRF52 UF2 bootloader whose model is earlier than 0.6.1, you won’t be able to load CircuitPython 8.2.0 and later, as a result of elevated dimension of the firmware. See these directions for updating your bootloader.
Notable modifications since 9.0.0
Audio
RP2040 I2SOut helps BLCK and LRCLK in both order.
Constructed-in modules
Improve collections.deque performance.
Add keypad_demux.DemuxKeyMatrix: use multiplexer for one aspect of a keypad matrix.
Add integration-based debouncing to keypad.
Inner
Espressif: replace to ESP-IDF v5.2.1.
Obtain from circuitpython.org
Firmware downloads can be found from the downloads web page on circuitpython.org. The location makes it simple to pick out the right file and language in your board.
Set up
To put in comply with the directions within the Welcome to CircuitPython! information. To put in the most recent libraries, see this web page in that information.
Strive the most recent model of the Mu editor for creating and enhancing your CircuitPython packages and for straightforward entry to the CircuitPython serial connection (the REPL).
Documentation
Documentation is offered in readthedocs.io.
Port standing
CircuitPython has a variety of “ports” which can be the core implementations for various microcontroller households. Stability varies on a per-port foundation. As of this launch, these ports are contemplate steady (however see Recognized Points under):
atmel-samd: Microchip SAMD21, SAMx5x
cxd56: Sony Spresense
espressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C3
nrf: Nordic nRF52840, nRF52833
raspberrypi: Raspberry Pi RP2040
stm: ST STM32F4 chip household
These ports are thought of alpha and can have bugs and lacking performance:
broadcom: Raspberry Pi boards comparable to RPi 4, RPi Zero 2W
litex: fomu
mimxrt10xx: NXP i.MX RT10xxx
silabs: Silicon Labs MG24 household
stm: ST non-STM32F4 chip households
