New Features
############
Concepts
--------

Improvements
############

- Fixed a bug in :ref:`LoadNGEM <algm-LoadNGEM>` where precision was lost due to integer arithmetic.
- Prevent units that are not suitable for :ref:`ConvertUnits <algm-ConvertUnits>` being entered as the target unit.

- Fixed an uncaught exception when plotting logs on single spectrum workspaces in mantidworkbench
- Save the units for single value logs in :ref:`SaveNexusProcessed <algm-SaveNexusProcessed>`
Algorithms
----------

Improvements
############

- :ref:`SaveAscii <algm-SaveAscii>` can now save table workspaces, and :ref:`LoadAscii <algm-LoadAscii>` can load them again.
- :ref:`TotScatCalculateSelfScattering <algm-TotScatCalculateSelfScattering>` will calculate a normalized self scattering correction for foccues total scattering data.
- :ref:`MatchAndMergeWorkspaces <algm-MatchAndMergeWorkspaces>` will merge workspaces in a workspace group withing weighting from a set of limits for each workspace and using `MatchSpectra <algm-MatchSpectra>`.
Data Objects
------------



Geometry
--------

Improvements
############

- Increased numerical accuracy when calculating the bounding box of mili-meter sized cylindrical detector pixels.



- added :py:meth:`mantid.api.Run.getTimeAveragedStd` method to the :py:obj:`mantid.api.Run` object

:ref:`Release 4.3.0 <v4.3.0>`
