Ruby 1.9
I was looking for the hash syntax in Ruby 1.9 as I could recollect that it has changed but did not remember it exactly and discovered this site that has all the changes in Ruby 1.9 in one place and in order. I know you can read “Programming Ruby 1.9” by Dave Thomas but then again this site would be extremely handy when you are upgrading your gems to Ruby 1.9. I wonder how many people have actually started using ruby 1.9. I do have it installed as a different binary (ruby19) but I have not been using it really.
