  • The fix for the OPL cutoff bug introduced in libopenmpt 0.6.7 was incomplete.
  • ULT: Offset commands exceeding 65535 samples were sometimes not imported correctly even if there was room for them.
  • After seeking with seek.sync_samples=1, the filter settings of playing notes were not updated since libopenmpt 0.6.7.
