Can someone please clarify what justifies the 3.2 -> 4.0? I don't see a big change, isn't this more like a 3.2 -> 3.3?
Rails 4.0 drops support for Ruby 1.8.x which necessitates the major version bump.
From what it looks like to me, it's not so much about a drastic new feature set but rather about trimming down dramatically. You could argue that it really should be like 3.2 -> 3.3 similar to OSX Leopard -> OSX Snow Leopard. I think they gave it a full version upgrade because it WILL (not might) break a lot of apps. That's my interpretation. I might be wrong.
Ruby 1.9.3+ justifies the major version bump
Part of it could be PATCH replacing PUT.
Have they announced a release date target?
Rails 4.0 might be out by the end of the year, but that's outside of my definition of "around the corner".
Upgrading our rails-2.3/ruby-1.8 website any day now.
Any word on performance?
Aaron Patterson (tenderlove) gave a presentation where he said he wanted to refactor rack to make it more simple. He said Rails 3 had a lot more depth in the stack and it was making it slower. (when i start up an old rails 2 app i can't believe how fast it is). I don't think that is in Rails 4 though. I guess that is a separate project.
Also deprecating vendor/plugins means Heroku will have to change the way they deploy. You can notice that by the deprecation messages when you start a heroku console.
