  • Up to 10 USERVARS supported with Monitor_nD (named user0,...,user9)
  • Qt5 → Qt6 across the package and dependencies
  • Bugfix: Fix of rare visualisation bug in mcdisplay/mxdisplay (e.g. box was not allowed as a comp name)
  • Doc improvements:
    • mcdoc/mxdoc can render .tex and .md in addition to .html
    • Example instruments come with an in-repo README.md generated via this mechanism
    • See e.g. McStas BNL_H8 or McXtrace ESRF ID01
  • CI/test improvements:
    • mcdisplay/mxdisplay visualisation is performed as part of mctest/mxtestruns (→ CI)
    • See top html files in McStas and McXtrace nightly test runs

McStas specific developments:

  • PowderN now supports NCrystal cfg-strings.
    • Forwards request to NCrystal that populates datastructures without intermediate .laz/.lau files
    • See example instrument Test_Powders - comp=0 mode
