Ruby on Rails Steams Ahead With 3.0 Release
It’s been two years in the making, but Ruby on Rails 3.0 is finally here. You can grab the third generation of the popular web framework from the official website, or update via the command line with:
gem install rails --version 3.0.0
Rails 3 is a major overhaul for the framework and merges the Rails and Merb frameworks to create a single lightweight code base for web applications written in Ruby.
The goal for this release was to make Ruby on Rails faster and more modular. Developers can now mix and match libraries, swapping out their favorites for Rails’ default choices.
If you’d like to know what’s new, what’s changed and why you might want to upgrade to Rails 3.0, head over to the Ruby on Rails screencast page, which has videos covering the biggest changes in the new release, as well as a number of smaller, but very useful new features.
