This article will explain in detail the changes in the official release of Ruby On Rails 3.0. the editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

After nearly 2 years of testing, Ruby On Rails 3.0 has finally been officially released. During this period, nearly 1600 developers participated in the development, and with the joint efforts of everyone, Ruby On Rails 3.0 appears to be "faster, stronger and more beautiful". I believe that the new version will not disappoint.
