.. currentmodule:: sherpa.utils

.. automodule:: sherpa.utils

.. versionchanged:: 4.17.0
   The parameter guess routines, such as `guess_amplitude` and
   `param_apply_limits` should now be taken from the
   :py:mod:`sherpa.utils.guess` module.

.. versionchanged:: 4.16.0
   The `parallel_map` function should now be taken from the
   :py:mod:`sherpa.utils.parallel` module and the numeric types
   (`SherpaFloat`, `SherpaInt`, and `SherpaUInt`) from the
   `sherpa.utils.numeric_types` module.
