This release of MicroPython adds support for ESP32-C5 and ESP32-P4 microcontrollers. The ESP32-P4 can work either standalone as a general purpose processor, or with an external wireless co-processor, currently either an ESP32-C5 or ESP32-C6. Board profiles are provided for all three of these configurations, as well as for the new ESP32-C5.

Support for the low-power and high performing STM32U5...

This release of MicroPython sees the introduction of machine.I2CTarget, which allows Python code to implement an I2C target device. It's available on the alif, esp32, mimxrt, rp2, samd, stm32 and zephyr ports. In the simplest case it can create an I2C register/memory device that connects to a bytearray (or similar buffer) and allows an I2C controller to read from and write into that bytearray....

After more than three years in development, the "ROMFS" feature has been finalised, its filesystem format specified, and the VFS driver and supporting code are included in this release of MicroPython. This feature builds on bytecode version 6 (available for many years now), which supports executing bytecode in-place, that is, without the need to copy it to RAM. ROMFS defines a read-only, memory-m...
