When will Rails 3 be formally released (as the stable, recommended version)?

I've heard they're targeting RailsConf - but it's really anyone's guess. The frequency of commits doesn't seem to be decreasing.

Dive in, the water's fine! You may experience a few bumps along the way, but there are a lot of people already in the water ready to help you out. There are already production apps running Rails 3--just don't use it for anything mission critical.

I think that was what the parent's question was: when will it be ready for "anything mission critical"?

Nice. Anyone have experience with Paperclip on Rails 3? Almost all my apps rely heavily on Paperclip for image storage.

Nope, but all of these people do: http://railsplugins.org/plugins/161-paperclip

Railsplugins.org has been an invaluable resource for me to figure out what's happening with plugin and gem compatibility.

Now if they just added a JSON layer so I could automate the process of checking my projects' gems...

Paperclip w/ Rails 3 beta is kind of a moving target right now. As of yesterday, the rails3 branch of the main repo wasn't working in my only Rails 3 app, but this fork works for me: http://github.com/enable/paperclip/tree/rails3

I have, and it works.

I can confirm that Paperclip does work with Rails 3. Some recent merges and updates broke it for awhile, but I think things are back to normal now. (If not, a pre-March fork of the rails3 branch will do in a pinch.)

Wow, RailsDispatch is one of the highest quality rails3 resources on the net. Props to engineyard for setting it up! This article was especially useful to me.

I'm thinking of learning Rails (currently on Python/Django). However I don't want to put all the effort into learning Rails 2 if there are going to be a lot of changes. Is it worth waiting until Rails 3 comes along, or should I just dive in now ?

Dive in now. I am using Rails 3 for our new project and it works perfectly fine. There are no real reasons to spend effort on building something on Rails 2.3 now. Especially, given that Rails 3 has significant improvements and is a pleasure to work with.
