From the GitHub release page:
This is CircuitPython 9.0.0, the latest major revision of CircuitPython, and is a new stable release.
WARNING for nRF52 boards only: If your board has an nRF52 UF2 bootloader whose version is before 0.6.1, you will not be able to load CircuitPython 8.2.0 and later, due to increased size of the firmware. See these instructions for updating your bootloader.

To install follow the instructions in the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.
Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).
Documentation is available in readthedocs.io.
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 (but see Known Issues below):

: Microchip SAMD21, SAMx5xcxd56
: Sony Spresenseespressif
: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C3nrf
: Nordic nRF52840, nRF52833raspberrypi
: Raspberry Pi RP2040stm
: ST STM32F4 chip familyThese ports are considered alpha and will have bugs and missing functionality:
