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

libopenmpt 0.7.4 (2024-03-03)

  • [Bug] Makefile: libopenmpt 0.7.3 broke running the test suite for Emscripten builds.

  • openmpt123: openmpt123 now uses a narrower layout on terminal windows with a width of less than 72 characters.

  • Setting all possible load_skip flags resulted in nothing being loaded at all, instead of just not loading the selected module parts.
  • When playing all subsongs, set_position_seconds didn’t always calculate the correct subsong to jump to.

  • IT: A few more compatibility flags are now disabled for modules saved with earlier Schism Tracker versions.
  • IT: MIDI macros were reset in IT 2.14 / 2.15 files that declared to be compatible with older IT versions (fixes spx-visionsofthepast.it).
  • OKT: Work around missing negative arpeggio implementation by transposing the notes up an octave.
  • OKT: Channel volume commands were sometimes lost over less important effects.
  • IMF: Ignore magic bytes in sample header. “Leaving All Behind” by Karsten Koch uses unexpected magic bytes, Orpheus ignores them just like the instrument header magic bytes.

  • zlib: Update to v1.3.1 (2024-01-22).
  • mpg123: Update to v1.32.5 (2024-02-17).
  • pugixml: Update to v1.14 (2023-10-01).
