Patch Version 5.1.1 is now available

We would like to announce a patch release, 5.1.1, of Mantid to correct some issues discovered in the recent 5.1.0 release.

The main issues fixed are:

  • a bug in the Muon interface that lead the error reporter to repeatedly appearing when incrementing
    the run number with sequential fitting enabled has been fixed
  • a bug in the Muon interface that lead to error bars being lost on fitted data has been fixed
  • fixed a bug where import CaChannel would cause a hard crash within MantidWorkbench on Linux
  • updated the ISIS Reflectometry live data monitor to work with new instrument PV names
  • corrected the table value for a partially invalid, filtered log, with only one remaining entry
  • fixed a bug where Muon Analysis would crash when using default grouping with no runs
  • fixed an unhandled exception when marking columns in a table workspace for plotting or deleting rows
    from a PeaksWorkspace
  • updated ALC documentation to clarify instrument used for data loading
  • avoid error reporter on entering comma in scale box in MSlice

Installation packages can be found on our download page and in the usual repositories. You can also access the source code on GitHub release page.
