Notes for Application Developers

New function in libpulse: pa_stream_write_ext_free(). The function allows more \ 
flexible use of free callbacks than the regular pa_stream_write() function. This \ 
is useful if an audio buffer is part of a bigger structure that needs to be \ 
freed or unreferenced when the audio buffer is no longer needed.

We now have Vala bindings for libpulse-simple.
