Rails 4.0 is out

After 10,000 commits, 2,223 file changes and over 500 contributors just in 2013, the rails core team has announced today the final release of Rails 4.0:

Rails 4.0 is finally ready after a thorough process of betas and release candidates. It’s an amazing new version packed with new goodies and farewells to old features past their expiration date.

One of the main focuses for this major release is to be able to create modern, super fast web applications without having to go the client/server json route (e.g. using backbone.js or ember.js). There are 4 new features that will help rails achieve this goal:

• Built-in Russian doll caching support
• Turbolinks
• Declarative etags
• Live Streaming

We’ll dive deeper into each of these new features in upcoming posts so stay tuned!
