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

libopenmpt 0.6.6 (2022-09-25)

  • [Sec] Possible crash when playing manipulated IT / MPTM files with a T00 command. (r17789)

  • MTM: In MultiTracker, setting speed and tempo are mutually exclusive commands. Still, some MultiTracker modules were made to be played with external players such as DMP, so they actually rely on “standard” speed / tempo behaviour. Decide which behaviour to use by checking of speed and tempo commands are found on the same row.
  • MTM: Ignore sample loops if the loop end is <= 2.
  • Echo DMO: Migrate left and right delay values in modules made with OpenMPT versions between 1.27.01.00 and 1.30.05.00 to the correct interpretation.

  • FLAC: Update to v1.4.1 (2022-09-22).
