CircuitPython 8.2.6 Launched! @circuitpython « Adafruit Industries – Makers, hackers, artists, designers and engineers!

From the GitHub launch web page:

That is CircuitPython 8.2.6, the newest bugfix revision of CircuitPython, and is a brand new secure launch.

WARNING for nRF52 boards solely: In case your board has an nRF52 UF2 bootloader whose model is earlier than 0.6.1, you will be unable to load CircuitPython 8.2.0 and later. The 8.2.0 firmware is bigger than what the bootloader can deal with. See these directions for updating your bootloader.

Notable adjustments to eight.2.6 since 8.2.5

• Up to date TLS root certificates to assist servers utilizing Let’s Encrypt.

Obtain from circuitpython.org

Firmware downloads can be found from the downloads web page on circuitpython.org. The positioning makes it simple to pick the proper file and language in your board.

Set up

To put in observe the directions within the Welcome to CircuitPython! information. To put in the newest libraries, see this web page in that information.

Strive the newest model of the Mu editor for creating and enhancing your CircuitPython applications and for simple entry to the CircuitPython serial connection (the REPL).

Documentation

Documentation is out there in readthedocs.io.

Port standing

CircuitPython has various “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 secure (however see Recognized Points beneath):

• 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-about alpha and could have bugs and lacking performance:

• broadcom: Raspberry Pi boards resembling RPi 4, RPi Zero 2W
• litex: fomu
• mimxrt10xx: NXP i.MX RT10xxx
• silabs: Silicon Labs MG24 household
• stm: ST non-STM32F4 chip households

Modifications since 8.2.5

Fixes and enhancements

• Add TLS root certificates to deal with servers utilizing Let’s Encrypt. #8386. Thanks @dhalbert.
• Make SSLContext.load_verify_locations() not require key phrase argument. #8392. Thanks @dhalbert.

Recognized points

• ESP32-S3 has vital points with I2C gadgets that sleep or use clock stretching. Retry operations on these gadgets as crucial, or use ESP32-S2 boards.
• Espressif boards have ESP-IDF storage leaks and infrequently crash after prolonged WiFi use.
• See https://github.com/adafruit/circuitpython/points for different points, together with points nonetheless to be addressed for:
