Rafael,
Jon Pike has now pretty much finished off all the testing we have time for, and we've covered off most of the important, useful packages.
Our results, for the record, are at
http://213.107.207.131:8000/rc1-results
We may get time to fix some of the issues we've found over the next few weeks, and I'd like to encourage ANYONE who can help fix these things to do so.
I realise Don is very busy, but I'm sure we'd be happy to help ensure patches and stuff are worked into the release (maybe with some testing).
As you can see (and there a couple to do) there are some issues around which do need resolving, but our general feeling is that time Vs quality indicates the release should be good to go. I think most of the probs we've found are ones easily resolved once someone comes to use the package.
Hope that helps, and in the future, if we can get more people to contirbute some testing effort I'm sure we can get release out more quickly. With Hub.Org now generously helping out with testing space/hosting we're really getting there.
Cheers
Simon
