CircuitPython 10.0.0-alpha.6
This is CircuitPython 10.0.0-alpha.6, an alpha release for 10.0.0. Further features, changes, and bug fixes will be added before the final release of 10.0.0.
Highlights of this release
- Fix regression causing errors on ARM processors.
Incompatibility warnings
- Starting with 10.0.0-alpha.5, the Adafruit Feather S3 4MB Flash 2MB PSRAM board requires TinyUF2 bootloader 0.31.0 or later (update instructions). This version of the bootloader removes the OTA update partition (not used) and doubles the size of the firmware code partition. This change for this particular board is a trial. If all goes well, all 4MB Flash ESP32-S2 and ESP-S3 boards will have this change applied in a later 10.0.0 alpha or beta release.
synthio.BlockBiquadhas been renamed tosynthio.Biquad. The old deprecatedsynthio.Biquadhas been removed, as well assynthio.Synthesizer.low_pass_filter,synthio.Synthesizer.high_pass_filter, andsynthio.Synthesizer.band_pass_filter. Coefficients frombiquad_filter_statehave been moved intosynthio_biquad(biquad_filter_stateis still used for input and output state).- The

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 (but see Known Issues below):
atmel-samd: Microchip SAMD21, SAMx5xcxd56: Sony Spresenseespressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6nordic: Nordic nRF52840, nRF52833raspberrypi: Raspberry Pi RP2040, RP2350stm: ST STM32F4 chip family
These ports are considered alpha and will have bugs and missing functionality:

CircuitPython 10.0.0-alpha.4
This is CircuitPython 10.0.0-alpha.4, an alpha release for 10.0.0. Further features, changes, and bug fixes will be added before the final release of 10.0.0.
This release is nearly the same as 10.0.0-alpha.3 but has a bug fix that breaks finalisers and results in "in use" errors. (Finalisers will usually release the resources.) It also fixes crashes on ESP32-CX RISC-V boards.
Highlights of this release
- A number of new audio effects.
- Improved garbage collection times
- ESP-IDF update to 5.4.1
- Improved audio playback on RP2

CircuitPython 9.2.7
This is CircuitPython 9.2.7, the latest bugfix 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.
Highlights of this release
- Bug fixes.
Incompatibility warnings
- Uses of deprecated
displayiobindings are now called out with warnings. For instance,displayio.Displayis deprecated in favor ofbusdisplay.BusDisplay. In CircuitPython 10.0.0 the deprecated bindings will be removed.
Download from circuitpython.org
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.
Installation
To install follow the instructions in the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.
Try code.circuitpython.org or 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
Documentation is available in readthedocs.io.
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 (but see Known Issues below):
atmel-samd: Microchip SAMD21, SAMx5xcxd56: Sony Spresenseespressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6nordic: Nordic nRF52840, nRF52833raspberrypi: Raspberry Pi RP2040, RP2350stm: ST STM32F4 chip family
These ports are considered alpha and will have bugs and missing functionality:
