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:

atmel-samd: Microchip SAMD21, SAMx5x
cxd56: Sony Spresense
espressif: Espressif ESP32-S2
nrf: Nordic nRF52840, nRF52833
raspberrypi: Raspberry Pi RP2040
stm: ST STM32F4 chip family

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

broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
espressif: ESP32, ESP32-S3, ESP32-C3
litex: fomu
mimxrt10xx: NXP i.MX RT10xxx
stm: ST non-STM32F4 chip families

Changes since 8.0.0

Fixes and enhancements

Deinit the reset pin when displayio.I2CDisplay() fails. #7563. Thanks @Neradoc.
Fix incorrect exception chaining. #7566. Thanks @jepler.

Port and board-specific changes

RP2040

Use lowest drive level for PIO (fixes Adafruit Scorpio USB resets). #7558. Thanks @jepler.

Spresense

Update Spresense SDK to version 2.6.0. #7553. Thanks @kamtom480.

Build and infrastructure changes

Update build_board_info.py to be compatible with sh module 2.0.0. #7566, #7564. Thanks @Neradoc and @jepler.

Known issues

ESP32-S3 has significant issues with I2C devices that sleep or use clock stretching. Retry operations on these devices as necessary, or use ESP32-S2 boards.
Espressif boards have ESP-IDF storage leaks and occasionally crash after extended WiFi use.
