// - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
// user switches the default device via the operating system's audio preferences, mini_al will automatically switch
// the internal device to the new default.
// - Add support for compiling the UWP build as C.
// - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
// when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
