Mantid Versions Save

This is a patch release that corrects some significant issues in version 6.9.0.

The changes are:

• A fix to stop workbench freezing when plotting data from a workspace that is changing (e.g plotting live data)
• Removed slit lookup that was specific to OFFSPEC in ReflectometryReductionOneLiveData as it is no longer required and was causing regular crashes when running live data on OFFSPEC.
• Fixed a bug in Elwin Tab of Data Manipulation Interface where changing integration range with the sliders did not change default integration range.
• Add sample log values to the live data workspace before the instrument is loaded in ReflectometryReductionOneLiveData to ensure log values are available when setting the detector positions.
• Fixed a crash when using multiple Indirect or Inelastic interfaces. This crash was present on the Bayes Fitting interface, but could also be replicated elsewhere.

We are proud to announce version 6.9.0 of Mantid.

This release includes a wide array of updates, bugfixes, and new features.

We would like to highlight the following improvements:

• The performance of the LoadAscii algorithm has significantly improved, achieving at least a one order of magnitude speedup.
• The IntegratePeaksShoeboxTOF algorithm has been added for integrating single-crystal Bragg peaks in a workspace with an x-unit of TOF using a shoebox.
• The FindPeaksConvolve algorithm has been added for 1D peak finding, and is available in the FitPropertyBrowser. It provides improved peak finding when compared to the FindPeaks algorithm.
• The option to open the sliceviewer directly from the Indirect and Inelastic interfaces for the output data has been added.

These are just some of the many improvements in this release, so please take a look at the release notes, which are filled with details of the important changes and improvements in many areas. The development team has put a great effort into making all of these improvements within Mantid, and we would like to thank all of our beta testers for their time and effort helping us to make this another reliable version of Mantid.

Throughout the Mantid project we put a lot of effort into ensuring Mantid is a robust and reliable product. Thank you to everyone that has reported any issues to us. Please keep on reporting any problems you have, or crashes that occur on our forum.
