 - :ref:`ConvertToPointData <algm-ConvertToPointData>` and :ref:`ConvertToHistogram <algm-ConvertToHistogram>` now propagate the Dx errors to the output.
 - The algorithm :ref:`CreateWorkspace <algm-CreateWorkspace>` can now optionally receive the Dx errors.
+- The algorithm :ref:`SortXAxis <algm-SortXAxis>` has a new input option that allows ascending (default) and descending sorting. Furthermore, Dx values will be considered if present. The documentation needed to be corrected.
