FluidSynth full changelog

Previous versions have incorrectly exposed private C++ and inline symbols; they are now hidden from the library
Fluidsynth now resets DataEntry values when it receives (N)RPN MSB/LSB to prevent off-tuned channels
It is now possible to install the library, header and executable independently from each other
Add a CI pipeline for iOS and publish precompiled iOS binaries for each release
Fix the precompiled Windows binaries lacking dependency libraries
Fix a regression introduced in 2.5.0, that could have caused a NULL pointer deref when playing AWE32 NRPN MIDIs
Fix a regression introduced in 2.5.0, that caused convex unipolar modulators to use a concave mapping
Fix a regression introduced in 2.4.6, which in rare cases could have caused the cutoff frequency of the IIR filter to get stuck or change abruptly
Fix a build issue where fluidsynth was trying to find glib even when it shouldn't
Fix typos in ALSA log messages

New Features:
Add a C++11-based OS abstraction layer as a replacement for glib, bringing these minor limitations when C++17 is unavailable (#1570, thanks to @mmlr)
Add native support for Downloadable Soundfont Format (#1626, thanks to @rsp4jack)
Fluidsynth now recognizes the DMOD INFO-subchunk (#1582, thanks to @spessasus)
A new positional flag has been introduced: -b, --bank-offset, (#1538, refer to UserManual for details)
Fluidsynth now natively supports the long CLI option flags on Windows (#1544)
Fluidsynth now supports native Android logging (#1621, thanks to @neoharp-dev)
Breaking Changes:
Support for SDL2 has been removed - pls. use SDL3 instead (#1594)
The processing order of fluidsynth's configuration files has been changed (#1573, refer to wiki for details)
The legacy shell commands for reverb and chorus have been removed (#1659, refer to UserManual for details)
Musically Breaking Changes:
It was discovered that fluidsynth was mapping some modulators slightly inaccurately into their normalized range (#1651, thanks to @baskanov)
Some Roland GS NPRN Params are now mapped to CC numbers (#1519, refer to wiki for details)
Fluidsynth now auto-detects whether Portamento Time is 7bit or 14bit wide - this fixes the infamous Descent Game08 tune (#705, #1232, #1311, #1456, #1495, #1517, see synth.portamento-time for details)
Previously, fluidsynth's default behavior was to use portamento only for those notes, that were played in a successive / legato manner; to further improve the portamento experience, this was changed and fluidsynth now plays portamento for all notes by default (#1656)
Other Changes:

Fix installing static and

Fix inconsistent library naming for MSVC vs. MinGW builds
Fix MIDI player skipping some events when seeking

Fix several issues when generating API docs with recent versions of Doxygen

Support for SDL3 has been added, support for SDL2 has been deprecated (#1485, #1478, thanks to @andyvand)
Soundfonts that are not respecting the 46 zero-sample padding-space previously sounded incorrect when
synth.dynamic-sample-loading was active (#1484)

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)

New Features:
Implement MSGS-style Drum Note Cut (#1199)

The behavior of the volume envelope's delay phase was previously incorrect (#1312)
The ModLfoToVolume generator was not able to increase the volume (#1374)

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
