For a detailed list of changes, pls. refer to the changelog in the wiki (work-in progress).

Pre-built binaries are provided for WindowsXP, Windows10 and Android API Level >=30 .

fluidsynth 2.1.7

• a regression introduced in 2.1.0 prevented chorus from being audible when fluid_synth_process() was used (#751, thanks to @chirs241097)
• a regression introduced in 2.0.6 prevented the MIDI player from restarting playback after all files have been played (#755, thanks to @rncbc)
• fix a double-free violation introduced in 2.0.0 after executing the info shell command (#756)

fluidsynth 2.1.6

SoundFonts may never be unloaded correctly, if

fluidsynth 2.1.4

• fix an uninitialized memory access possibly triggering an FPE trap
• fix several regressions introduced in 2.1.3:
  • fluid_synth_start() failed for certain presets
  • fix a NULL dereference in jack driver
  • fix a stack-based overflow when creating the synth
