// - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
// - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
// - Simplify the build system further for when development packages for various backends are not installed.
// With this change, when the compiler supports __has_include, backends without the relevant development
// packages installed will be ignored. This fixes the build for old versions of MinGW.
// - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
// audio data to a different format.
// - Improvements to f32 -> u8/s16/s24/s32 conversion routines.
