    - Multi-fabric support,
    - Better complex type support for sending commands,
    - Native command highlight,
    - Parallel commands with asyncio,
    - Writing complex logic inline.

    You can still use chip-device-ctrl as usual for now, and you will learn how to do the same thing in chip-repl.
