deprecations:
  - |
    ``OpenAPIConnector``, ``OpenAPIServiceConnector`` and ``OpenAPIServiceToFunctions`` are deprecated and
    will be removed from Haystack in version 3.0. They are moving to the ``openapi-haystack`` package. To
    continue using them, install the package with ``pip install openapi-haystack`` and update your imports
    as follows:

    .. code-block:: python

        from haystack_integrations.components.connectors.openapi import OpenAPIConnector
        from haystack_integrations.components.connectors.openapi import OpenAPIServiceConnector
        from haystack_integrations.components.converters.openapi import OpenAPIServiceToFunctions

    These components are a legacy way to connect Haystack to external APIs. For most use cases, consider
    using the ``MCPTool`` instead, which is the modern, standardized way to give pipelines and agents
    access to external tools and services.
