hAudio has reached a stately version 9.0 which I imagine will be the final proposal from the contributors of the hAudio Microformat.

Only one class name was changed, "fn" for "title" which doesn't seem so great but has been a hotly debated part of hAudio since May 2007 when the issue about "title is already taken to mean something else" and "use fn instead" first came up. The Class Name "title" may yet change again because the fn/title issue is still being debated and I imagine will continue for some time yet.

In the meantime the Grabb.it guys became the first major implementer of hAudio 0.9 marking up thousands of tracks on their userpages, I would say that they are quite happy with the changes made to the microformat.

hAudio RSS also uses the new hAudio microformat in the V3 version of the hypertext playlist format. New for Version 3, is a new home page on The ESW Wiki, hAudioRSS where you can download the entire source code and demo of the hAudio-RSS playlist.

If you are planning on marking up your pages in hAudio or hAudio-RSS let me know I will be more than happy to give you a shout for doing a good thing.
