◆ Streaming:HTTP Streaming is also a new improvement in Rails that allows browsers to download stylesheets and JavaScript files while the page responds. This feature requires Ruby 1.9.2, as well as support from the Web server.

◆ jQuery replaces prototype as the default JS library for Rails.

Note that Rails 3.1 requires Ruby version 1.8.7 or higher and is compatible with Ruby 1.9.2. Just in case, it is best to upgrade to Rails 3 before upgrading to Rails to ensure that it will work properly after upgrading to 3.1. Newly installed users strongly recommend using Ruby 1.9.2 (1.9.1 is not easy to use, and 1.8.7 contains the bug that caused Rails to crash).
