  - Improve the performance of the ``ConstrainedQuadraticModel.from_lp_file()`` method.

    to emit a warning now raise an error instead.
deprecations:
  - |
    Deprecate ``ConstrainedQuadraticModel.from_lp_file()`` method. Users should
    use the more explicit ``lp.loads()`` and ``lp.load()`` functions instead.
    The ``ConstrainedQuadraticModel.from_lp_file()`` will be removed in
    dimod 0.13.0.
  - |
    The ``default_lower_bounds`` and ``default_upper_bounds`` keyword arguments
    for ``ConstrainedQuadraticModel.from_lp_file()`` are deprecated and do
    nothing.
