Recently I got some time to start working on Rails4 with Ruby2.0. All I want to share is, I am late, but now I'm on it.. I am also preparing a document listing what all changes Rails4 has. But at this point of time, it's fun working with Rails4.
If anyone of you need any help feel free to comment on this thread. If in case, I need an advise, I will get in touch with you all on the same channel.
