features:
  - The public APIs from ``neutron.db.api`` are now available in

    are available in ``neutron_lib.db.api`` for convenient access as
    decorators.

upgrade:
  - Consumers using the global ``context_manager`` from ``neutron.db.api``
    should now use the ``get_context_manager()`` function in
    the ``neutron_lib.db.api`` module or the global ``CONTEXT_READER``
    and ``CONTEXT_WRITER`` if needed.
