This is CircuitPython 7.1.1, the latest bugfix revision of CircuitPython, and is a new stable release. It has fixes for RGBMatrix on RP2040 and PDMIn (microphone input) on SAMx boards, such as Circuit Playground Express. There are no other changes; unless you are affected by these problems, you do not need to upgrade from 7.1.0.

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.
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, atmel-samd, cxd56 (Spresense), espressif for ESP32-S2, nrf,raspberrypi, stm for the F4 family are stable. stm for other STM chip families is being actively improved but may be missing functionality and have bugs. broadcom (Raspberry Pi), espressif for ESP32-S3 and ESP32-C3, litex and mimxrt10xx are in an alpha state and will have bugs and missing functionality.
