Release Version 6.5.0

We are proud to announce version 6.5.0 of Mantid.

This release includes a wide array of updates, bugfixes, and new features, which build on the functionality of Mantid.
Users are reminded that this release has now dropped support for .rpm & deb files on Linux in favour of Conda installations or a standalone tarball. Please see the 6.4.0 release notes for more information.

In addition to many improvements we are delighted to announce some new features including:

• A new tab has been added to the ISIS Engineering Diffraction UI to support running refinements in GSAS-II.
• The ISIS powder diffraction scripts support the PaalmanPings correction method.
• It is now possible to use the algorithms from the GOFit optimization package directly with the Crystal Field API.
• The algorithm DiscusMultipleScatteringCorrection now simulates scattering in a container (and more generally in any sample environment components) if a user sets up the shapes and materials in the input workspace prior to running the algorithm.
• A new set of scripts has been produced to provide a method for processing OSIRIS data. ISIS Powder Diffraction Scripts - OSIRIS.
• Three new fitting functions: FickDiffusionSQE, ChudleyElliotSQE, and HallRossSQE have been made and added to :ConvFit
• Support loading and reducing data for the new detector for D16 at ILL.

Release Version 6.4.0

We are proud to announce version 6.4.0 of Mantid.

Many of the updates in this version have focused on improvements for users, building on existing algorithms and interfaces. Our method of packaging has also changed. Windows and macOS users should not notice any difference, but this will be the last release where we provide .rpm and .deb packages for Linux.

In addition to many improvements we are delighted to announce some new features including:

• A new cut viewer tool for non-axis aligned cuts has been added to the slice viewer.
• Workbench and MSlice are now compatible with matplotlib v3.5.
• In the ISIS Reflectometry interface, defaults can now be set according to both the angle and the sample title.
• Fit functions have been extended to allow for the addition of function attribute validators.
• The ISIS SANS TOML format has been upgraded to V1. All V1 files will continue to be supported in future versions without changes.
• An inelastic version of the discus multiple scattering correction algorithm has been implemented. This allows the multiple scattering effect to be simulated using a Monte Carlo integration for an arbitrary sample shape given an S(Q,w). The calculation can be run for a direct or indirect geometry instrument.

Release Version 6.2.0

We are proud to announce version 6.2.0 of Mantid.

This release sees many new algorithms added or improved to extend the functionality of Mantid for users. In addition to this there are some significant new features
including:-

• Superplot, a new widget that facilitates over-plotting and data comparison for a large number of workspaces.
• The ablity to plot CSGObjects as Sample shapes and merge shapes for greater complexity.
• In MSlice you can now enable powder (Bragg) peaks on cut plots.
• Maxent Dual Plotting for Frequency Domain Analysis allowing raw and reconstructed data to be plotted together along with the frequency domain data.
• A new widget and workspace plugin, the Workspace Calculator. This allows users to quickly perform binary operations on selected workspace pairs, optionally with scaling.
