Just found this interesting bit on alsa-devel. Now it's 'official': apps should support 0.9, and alsa 0.5 is just still around and "no longer supported from the developer perspective". And I'm glad, that PD supports 0.9 for a long time.

I can add something but what is the official view from Jaroslav?
0.5.x release is no longer supported from the developer perspective. All our focus is in 0.9.x codebase. I'll release 0.9.0rc1 ASAP (after fixing and testing a few changes), so it'll be clear that the API is finished and code is working.
It would be nice, if someone helps us with the doxygen documentation and cross-reference guide so we can release 0.9.0 final in a few months.
