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

libopenmpt 0.7.6 (2024-03-24)

  • [Sec] Potential heap out-of-bounds read or write past sample end with malformed sustain loops in SymMOD files (r20420).

  • MED: Transposed samples were playing too low in some files (e.g. mix94.mmd1).
  • OKT: Some files with garbage at the end were rejected (e.g. katharsis - piano lesson.okta).
  • Compressor DMO: It was possible that the plugin would not behave as intended at mix rates above 500 kHz.
  • Avoid re-allocating the loop state map contents on every playthrough of the module.
