Match! version 4.2 Build 341 has been released

December 4, 2025

The new Match! version 4.2 Build 341 is bascially a maintenance release, providing some minor improvements as well as fixes for all currently known bugs:

• When you import a CIF crystal structure data file that contains multiple data sets (e.g. for Rietveld refinement), you will now be asked which data set you would like to import.
• The most recent edition "December 2025" of the COD reference database is used.
• All currently known bugs have been fixed:
  • Several issues that might have caused the program to crash have been resolved.
  • A bug causing too low intensity values when using the "Counts" scaling of the diffraction pattern has been fixed.
  • Another bug that affected the number of CPU cores to be used for profile fitting search-match has been fixed. This bug could cause the profile fitting search-match not to work at all on machines with very few CPU cores or on virtual machines.
  • Due to a bug, PLV format diffraction data files could not be imported if the sample name contained the keyword "data".
  • Some minor bugs have been fixed as well.
