If you use this define, your application will work with next major ALSA
release (probably 1.0). Note that we have also ALSA_PCM_NEW_SW_PARAMS_API.

Yes, we'll remove deprecated functions, but not for 0.9.

I hope that this change was the last change before 0.9.0final, but as you
seen, we are trying to retain compatibility. So, old programs will work
with newer ALSA libraries (at least for major ALSA releases) - note that
it does not work in opposite way - programs linked with newer libraries
can have trouble with older libraries.
I am sorry for late reply.
