Mantid Imaging 2.5#

This release brings some significant new features:

Stochastic PDHG Reconstruction

New reconstruction option from CIL. This gives faster convergence and lower memory usage by splitting the input data into subsets.

Golden Ratio datasets

Datasets recorded using the golden ration method can now be opened correctly, using angle information in the log file.

Performance improvements

Spectrum Viewer

Complete the base feature set of the Spectrum viewer.

User interface improvements

Improved Nexus Support

Windows Installer

See Installing with Windows installer

There have also been many smaller changes and fixes which are listed below.
