Thanks for 2k stars!

fluidsynth 2.4.3

• It was discovered, that exclusive class note terminations were too slow (#1467, thanks to @mrbumpy409)
• Fix a regression introduced in 2.4.0 that allowed the amplitude of a voice playing in delay phase to rise infinitely (#1451)
• MSGS drum-style note-cut has been converted to an opt-in setting synth.note-cut (#1466)
• Support for SDL2 has been disabled by default* (#1472)
• Fix a regression introduced in 2.4.1 that could have caused infinite audio gain output for some MIDI files under certain configurations (#1464)
• Silence a warning issued by Systemd v254+ (#1474, thanks to @andrew-sayers)

*It was found that SDL2 hijacks fluidsynth's main() function which causes build problems on Windows, see (#1472). A PR for migrating to SDL3 is highly welcome! If you still want to compile with SDL2 support, you need to explicitly enable it using CMake flag -Denable-sdl2=1.

fluidsynth 2.4.2

• Fix audible clicks when turning off voices while using a high filter resonance (#1427)
• Fix a build failure with MSYS2 and MinGW when processing VersionResource.rc (#1448, thanks to @pedrolcl)
• Fix a crash on startup when there are no MIDI devices available on Windows (#1446, thanks to @pedrolcl)
• Restore discovery of libsndfile (#1445)
• Fix a race condition when loading SF3 files containing multiple uncompressed samples (#1457)

fluidsynth 2.4.1

• Enable libsndfile to use filename with non-ASCII characters on Windows (#1416, thanks to @pedrolcl and @stardusteyes)
• Fix a few commandline encoding related issues on Windows (#1388, #1421, thanks to @pedrolcl)
• Fix build errors on Windows (#1419, #1422, thanks to @carlo-bramini)
• Fix clicks and pops caused when changing parameters of the lowpass filter (#1415, #1417, #1424)
• Minor adjustment to AWE32 NRPN behavior (#1430)

fluidsynth 2.4.0

New Features

• Implement MSGS-style Drum Note Cut (#1199)
• Support KAI audio driver on OS/2 (#1332, thanks to @komh)
• Add support for AWE32 NRPNs (#1346)

Breaking Changes

• LASH support has been removed (#1285)

Musically Breaking changes

• The default settings for reverb and chorus have been tuned to provide a more natural perception (#1282, thanks to @es20490446e)
• The behavior of the volume envelope's delay phase was previously incorrect (#1312)
• The ModLfoToVolume generator was not able to increase the volume (#1374)
• Fluidsynth's default device-id was changed, allowing it to process (most) SysEX events without further configuration (#1382)
• Previously, some modulators were treated in a non-standard way (#1392, #1389, #1068)

Bug Fixes

• The former linear interpolation of IIR filter coefficients could have caused audible clicks and cracks (#1345) - yet there is still a potential for clicks and cracks, see #1415
