for those of you using rails 3, are you going to be using this rc candidate, or the ruby 1.9.1-p429. I've ran into a lot of issues using ruby 1.9.1 and are either fixed using ruby 1.8.7 or ruby 1.9.2 .. so just wondering ?
Yes, we absolutely will be. We were running 1.9.1 (can't remember which patch level off hand) in a stable config with Rails beta 1, but as the Rails beta progressed, we were unable to move forward with ruby 1.9.1 underneath. This morning, we moved our staging environment to ruby-1.9.1-rc2 and rails-3.0.0.beta4. All our testing since this morning has gone 100% smoothly (thank god!). Every increment in beta before this point has been a nightmare.
That said, I am using 1.9.1 in production (non-Rails project) and have had almost no issues so far, apart from a few libraries that had to be updated, but that was mostly minor issues (e.g. #methods returns strings in 1.8 and symbols in 1.9).
I'm using 1.9.1 right now for development, but may make the switch to 1.9.2 - the only issue I've encountered on 1.9.1 with Rails 3 are problems with encodings and multibyte characters.
The way I understand it, the Rails team recommends not trying to use 1.9.1 with Rails 3 -- too many problems. Recommended versions are 1.8.7 and 1.9.2 pre-releases.
