Check out the change-log for all the details.
A pretty cool feature that hides behind the "RFC 5019" improvement is that you can now cache OCSP responses. If you use HTTP GET you will be able to use simple network components like a HTTP/1.1 cache (Apache httpd config included in the docs) for caching and load-balancing between your responders. I'd love to see someone try this out on a massive scale and report back to me with some statistics.. =)
