Version 0.3.2

- sfizz now builds down to gcc-4.9 with stricter C++11 compliance. The main release builds use C++17 mode on newer compilers (sfztools#111, sfztools#110)
- Upstream libraries updates (abseil, filesystem and atomic_queue) (sfztools#121)
- Added an experimental support for `make uninstall` (sfztools#118, sfztools#120)
- Add the autopan (sfztools#105), width, rectifier, gain, limiter (sfztools#131), and string resonator (sfztools#143) effects
- Curves are now registered within the synth but cannot be referenced yet (sfztools#96)
- Corrected a bug where the VST plugin got recreated needlessly in some hosts (sfztools#122)
- Added a "panic button" API that kills voices (sfztools#122)
- Corrected a potential overflow for CC names (930bfdf)
- Added support for more generators using wavetables (sfztools#61)
- Added support for the `oscillator` opcode, to create generators from files (sfztools#128)
- Generators using wavetables are now correctly tuned (sfztools#126)
- The stereo panning stage of the process was corrected; width is now set to 100% by default as it should, and panning is properly applied (1faa7f, b55171, sfztools#133)
- The logging API can be used to set a log filename (a6cbb48)
- Corrected errors in the performance report script related to display values (file names and histogram range)
- Reworked the parser; the new one is more efficient, and can indicate error/warning ranges (sfztools#130)
- The VST plugin now reloads the file automatically, like the LV2 plugin (sfztools#139)
- The max number of CCs was increased to 512, to accomodate some libraries that use cc300 modifiers.
- The engine uses floating point values internally for midi events (sfztools#137); this prepares it for high-resolution midi down the line.
- Fixes some realtime synchronization issues in the VST (sfztools#140)
- Added support for `note_polyphony`, `polyphony`, and `note_selfmask` (sfztools#142)
- Added support for `pitch_cc` and `tune_cc` modifiers (sfztools#142)
- The modifier support was overhauled; all regions can now have multiple CCs modifying the same target (sfztools#142).
- Corrected bugs and differences with Cakewalk/ARIA in the ADSR envelope (sfztools#136, sfztools#129)
- Improved performance of the amplitude stage gain of the rendering process (sfztools#145)
- The VST3 are now a submodule; more architecture targets have been added (sfztools#158, sfztools#147, patch proposed by @hexdump0815)
