## AI overview

CircuitPython 11.0.0-alpha.3 adds web workflow display mirroring; Raspberry Pi Pico board-level I2C, SPI, and UART helpers; early video pipeline support; audio tools; awaitable SPI transfers; and Espressif hardware key and cryptography support. It also improves MIDI playback and speeds up display, image, and JPEG operations. Libraries from 10.x bundles remain compatible, but upgrading can require changes: the broadcom, litex, and renode ports were removed; OnDiskBitmap now accepts a filename rather than an open file; and Espressif processor IDs and USB serial numbers change. This is an alpha release, and port stability varies: ESP32-P4, Zephyr, and several other listed ports remain alpha, with bugs or missing functionality expected.
