Ruby On Rails 3.0 officially released faster, stronger, and more beautiful

It took nearly two years. After multiple test versions, Ruby On Rails 3.0 was officially released. Over 1600 developers participated in the development. With the joint efforts of everyone, Ruby On Rails 3.0 was "faster, stronger, and more beautiful". I believe the new version will not disappoint you.

The Ruby On Rails 3.0 official version has changed a lot, so it is very difficult to pick out outstanding features. Here we will introduce some major changes in the new version.
