Inelastic Changes
=================

New Features
------------
- (`#40595 <https://github.com/mantidproject/mantid/pull/40595>`_) :ref:`Bayes Fitting interface <interface-inelastic-bayes-fitting>` has a new combo box to swap between using the ``quasielasticbayes`` (old Fortran library) backend and the ``quickbayes`` (new python library) backend. Changing this box won't effect the functionality of the ResNorm tab, which already uses ``quickbayes``.
- (`#40897 <https://github.com/mantidproject/mantid/pull/40897>`_) The :ref:`Bayes Fitting interface <interface-inelastic-bayes-fitting>` will now plot result workspaces as a contour plot if the workspaces contain multiple spectra.
- (`#40897 <https://github.com/mantidproject/mantid/pull/40897>`_) The :ref`algm-BayesStretch` algorithm now outputs contour and fit workspace groups with the name provided in the ``OutputWorkspaceContour`` and ``OutputWorkspaceFit`` input properties.

Algorithms
----------

New features
############
- (`#40323 <https://github.com/mantidproject/mantid/pull/40323>`_) A new algorithm :ref:`SpectralMomentMD <algm-SpectralMomentMD>` can now be used to calculate sum rules for inelastic multi-dimensional event workspaces.

Bugfixes
############
- (`#40650 <https://github.com/mantidproject/mantid/pull/40650>`_) :ref:`BayesQuasi <algm-BayesQuasi>` now respects the ``OutputWorkspaceProb`` and ``OutputWorkspaceResult`` parameters.

:ref:`Release 6.15.0 <v6.15.0>`
