We are proud to announce version 6.11.0 of Mantid.

In this release we gave extra attention to fixing bugs and improving algorithms (for example by making them run faster or use less memory). We also added several new algorithms. These are the highlights for this release:

  • There is a new Deprecation Policy for Mantid. One of the main changes is that we will deprecate algorithms that have not been used for 3 years or more.
  • For single crystal diffraction, we added a new algorithm FindMultipleUMatrices to find multiple UB matrices when given lattice parameters for sample with multiple domains or spurious peaks.
  • Also for single crystal diffraction, IntegratePeaksSkew is better at determining background bins by minimising third-moment (skew). This is achieved by forcing skew > 0 (minimum skew we would expect in background). This change stops peak mask of IntegratePeaksSkew including too many pixels due to small diffuse scattering.
  • For powder diffraction, the algorithms AlignAndFocusPowder, AlignAndFocusPowderFromFiles, SNSPowderReduction and LoadEventAndCompress were updated to use logarithmic compression, which uses less memory.
  • For reflectometry, we added a new algorithm PolarizationEfficienciesWildes for calculating the efficiencies of the polarizing components of an instrument with two flippers. This algorithm implements the approach from the A. R. Wildes 2006 paper doi: 10.1080/10448630600668738.
  • For SANS, we added new algorithm PolarizerEfficiency for calculating the efficiency of a polariser.
  • For Inelastic, renamed tabs of QENS Fitting from MSD Fit, I(Q,t) Fit, ConvFit and F(Q) to MSD, I(Q,t), Convolution and Function(Q) respectively.
  • For Inelastic, the Elwin Tab of Data Processor Interface now includes access to the Slice Viewer or 3D Plot from the output plot widget of the output workspaces containing more than 1 histogram.
  • Again for Inelastic, QENS Fitting Interface now allows loading a _Result workspace from the I(Q, t) fitting tab into the Function (Q) fitting tab if one of the fit parameters is A0.
  • Finally, for developers, the Mantid developer environments are now created using a new mantid-developer Conda meta-package, hosted on our Conda channel. This change does not affect users but greatly simplifies our development process, as package dependencies are now automatically sorted on different operating systems.

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.
