Add a curve fitting page to the MantidPlot settings dialog to allow setting the AutoBackground property. Also fixed a minor issue in the Config service saveConfig that was overly zealous with adding new line endings to the saved file. Re #1310

Added a couple of parallel protected regions to Q1D as it was giving different answers on multiple runs. Note that it still gives a difference of about 10^-14 between multiple runs but I believe this is due to limitations of OpenMP and summing double precision numbers in different orders. Re #1217

In the centre finder the sample workspace was being deleted before it was needed by the can processing re #1285

Updated test. Note there is room to be more clever than the simple cutoff of 10*sigma for the Back-to-Back exponential, since the alpha and beta parameter also affects this width. Also for speed efficiently would we want the user to be able to specify a cutoff as is done with e.g. Fullprof? 10*sigma corresponds to the most conservative cutoff used when analysing HRPD data with Fullprof. Refs #1307.

Converted Back-to-Back exponential parameters to output in d-spacing units. Also, adjusted peak shape function such that when more than 10 sigma away from centre of peak zero is returned. Tests indicate that fitting multiple HRPD peaks are now even faster. Refs #1307.

Fix for SANS centre-finder crashes along with a problem with the residue graph if it was closed prematurely. Re #1285

Replace boost_python debug libraries with ones linking to python debug build. Changes to PythonAPI project file to link everything correctly. Now python scripting works in my debug MantidPlot! (if I comment out a couple of lines in PyAlgorithmWrapper.cpp) Re #1305.

Alleviate problems with WorkspaceGroup crashes. The Fit browser was causing a crash while cheking a group member that was being deleted. Problem not solved, WorkspaceGroups just temporarily disabled within the Fit browser. Re #1285

The SANS GUI was writing a non-keyword argument after keyword argument error, this stops that re #1285

also submitting the DataHandling unit tests which I changed for removing the workspaces at the end of execution from ads .

In recent development versions colour plots were sometimes wrongly displaying uniform colour over the plot area despite the scale being OK.  Problems still remain with the colour bar displaying mostly white, they are listed in ticket 1265, but I believe data aren't being misrepresented and functionality is improved. Things to watch when changing this code: there are Qtiplot, Mantidplot and possibly Qwt ways of doing the same thing, choose the Mantidplot way and watch for unexpected results. re #1231

Improved speed at which numerical derivs calculated. Test with double peak Ikeda-Carpender gave good result. Refs #1233.

Refs #1267; event list now histograms by summing all events if no bins are set; event workspace tests correctly.

Added numerical derivative method (similar to that in UserFunction) which can optionally be called from a functionDeriv() function implementation. Added such an implementation for IC. Refs #1233.

The SANS GUI can now process a sample workspace contained in a multi-period workspace. Extensions to this will follow re #1285
