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

libopenmpt 0.8.8 (2026-08-15)

  • IT: Due to an Impulse Tracker bug in Compatible Gxx mode, Envelope Carry may not resume the envelope from the correct position when there is both an instrument number and tone portamento next to a note.
  • XM: NitroTracker ignores instrument numbers where there is no note next to them, so they are no longer imported. Fixes various NitroTracker-made XMs such as notominous-a19.xm.
  • STK: Loosen heuristics a bit to allow STK.CRB-GreatMuzaxs6 to load.

  • GT2: Loading file versions 6 and later was broken since libopenmpt 0.8.0.

  • mpg123: Update to v1.33.7 (2026-08-03).
  • miniz: Update to v3.1.2 (2026-07-01).
  • pugixml: Update to v1.16 (2026-06-16).
