Rails 4 Countdown to 2013

With the impending release of Ruby on Rails 4, it looks like a lot of developers will be updating their web applications in the coming new year.

To help with this transition, over the next 31 days, we are going to be releasing a series of blog posts going over everything you will need to know about Rails 4 for an effortless upgrade.

Once a post is added to the series, a link will be added here for you to have a single destination to get your Rails 4 fix.

Rida Al Barazi, co-author of Beginning Rails 3, and myself will be sharing the writing duties.
