Help with google_base feed changes!

Hi All

Well google have introduced their planned changes so now my products have errors in google base feed. Has anyone worked out how to make the standard google base feed in 1.5x work completely with the new google base requirements eg. availability, google product category?

Thanks

I need this too all my products have been disapproved

I worked out how to do it, but I'm afraid I had to make it in to an extension
