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

The vast majority of development effort for user interfaces is now directed towards the :doc:`Mantid workbench <mantidworkbench>`, for now only significant bugs will be fixed within MantidPlot.

- Saving a project larger than 10GB produces a pop-up to inform it may take a long time and gives the opportunity to cancel.

Bugfixes

- Sample Transmission Calculator no longer has the option to change the Y-axis of the plot to logarithmic.
