Many congratulations to the IP team on this release!
We should be able to start the process of properly porting Resolver One
to IP 2.0 RC1 in a week or so (we're just finishing off a release of our
own), but we've been tracking the betas up until now (as you might have
noticed from Michael Foord's emails), so we don't expect any major
issues. Of course, if anything does break you'll be the first to know :-)
Regards,
Giles
