    Deprecate old backports and typing alias

    Marc Mueller1 min read

    Core and integrations

    In the past, we've backported features from upstream CPython to use them early and improve user and developers' experience. Home Assistant only supports Python 3.12, so these can be used directly from Python. These backports are now deprecated and will be removed in the future.

    Deprecated Replacement Python version
    homeassistant.backports.enum.StrEnum enum.StrEnum >= 3.11
    homeassistant.backports.functools.cached_property functools.cached_property >= 3.8, >= 3.12 (performance improvement)

    In addition, some typing aliases are also deprecated now.

    Deprecated Replacement
    homeassistant.helpers.typing.ContextType homeassistant.core.Context
    homeassistant.helpers.typing.EventType homeassistant.core.Event
    homeassistant.helpers.typing.HomeAssistantType homeassistant.core.HomeAssistant
    homeassistant.helpers.typing.ServiceCallType homeassistant.core.ServiceCall
