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

libopenmpt 0.5.8 (2021-04-11)

  • [Sec] Possible null-pointer dereference read caused by a sequence of openmpt::module::read, openmpt::module::set_position_order_row pointing to an invalid pattern, and another openmpt::module::read call. To trigger the crash, pattern 0 must not exist in the file and the tick speed before the position jump must be lower than the initial speed of the module. (r14530)

  • [Bug] libopenmpt.pc did not list required system libraries ole32.lib and rpcrt4.lib on Windows in Libs.Private field for static builds.

  • [Bug] libopenmpt 0.5.7 broke seeking in some subsongs.

  • The built-in LFO plugin did not load the correct initial LFO frequency.
  • IT command S7x (instrument control) is now supported when seeking with sample sync enabled.

  • libopenmpt_ext play_note was cutting of channels even when there were plenty of free channels to use.

  • mpg123: Update to v1.26.5 (2021-03-22).
