Ruby on Rails has thrown open the doors to the first public beta edition of Version 5.0 almost 10 years to the day from when Version 1.0 debuted, and some 11 years and change after its very first release took flight. With the new update, Rails attempts to keep its existing user base and woo fresh adherents with a slew of new features.
The biggest change: Rails 5 runs exclusively on Ruby 2.2.2 and above. Rails' developers wanted to take advantage of the features and performance enhancements in that edition of Ruby, and they made this clear from the beginning of Rails 5's development.
