The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.4.4 (2019-04-07)

  • [Bug] Channel VU meters were swapped.

  • Startrekker: Clamp speed to 31 ticks per row.
  • MTM: Ignore unused Exy commands on import. Command E5x (Set Finetune) is now applied correctly.
  • MOD: Sample swapping was always enabled since it has been separated from the ProTracker 1/2 compatibility flag. Now it is always enabled for Amiga-style modules and otherwise the old heuristic is used again.

  • stb_vorbis: Update to v1.16 (2019-03-05).
