Version 3.12.1 is now available

Our most recent release of Mantid, v3.12.0, required an update due fix to some issues with the Muon Data Analysis interface. We have put together a patch release to address these issues and few others and we are pleased to announce that this is now available.

The main changes are:

  • Several fixes to the Muon Analysis GUI, including to the results table and fit menu.
  • Several issues which caused Mantid to crash have been fixed.
  • Allowing the live listener functionality to be used outside ISIS and from the python API.
  • Fixing the header for TOPAS files.
  • Removed the old version 1 of ReflectometryReductionOne and ReflectometryReductionOneAuto
