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

libopenmpt 0.8.3 (2025-09-06)

  • [Bug] libopenmpt is now compatible with most non-standard builds of libmpg123 which do not by default output signed 16bit PCM.
  • [Bug] openmpt123: Pausing playback using the space key did not work since 0.8.0.
  • [Bug] Windows 10 binaries wrongly targeted Windows 11 22H2. They now target Windows 10 2004.
  • [Bug] in_openmpt: in_openmpt for Windows XP or later did not ever work in Winamp 2.x. We now provide a build specifically for Winamp 2.x in the Winamp2/ folder inside the retro.winxp package. The retro.win98 build was not affected.

  • [Change] in_openmpt: Modern and legacy builds of in_openmpt now officially only support Winamp 5.x.

  • IT: Even when the filter cutoff envelope is stopped before its first tick is applied, the filter should still be activated.

  • mpg123: Update to v1.33.2 (2025-08-05).
