This is CircuitPython 7.1.0-beta.3, the fourth beta release for CircuitPython 7.1.0. It is relatively stable, but contains issues we may still address for 7.1.0. This release fixes a regression in 7.1.0-beta.2 that caused problems with displayio and possibly other problems.
Notable additions to 7.1.0 since 7.0.0
- Initial port for Raspberry Pi Broadcom-based boards.
- Preliminary support for
asynciocooperative multitasking. bitmaptools: dithering and alphablend are new.keypad.Events now include timestamps.framebufferio: support for IS31FL3741.- Espressif now provides
I2CPeripheral, WiFi monitor mode, setting MAC address, ESP32-C3 support,ParallelImageCapture. gifio.GifWriteris new.- HID now provides boot device and feature report support.
rotaryionow allows setting the divisor of counts per transition.- SAMD now provides
watchdog, andalarmwith sleep. - SAMx5 boards now all have sleep support.
- The STM port now provides STM32L4R5 support.
- MicroPython 1.17 has been merged in.
- Russian translation.

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, atmel-samd, cxd56 (Spresense), esp32s2, 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), litex and mimxrt10xx are in an alpha state and will have bugs and missing functionality.
