Official Rails Blog[Rails 4.2.0 Release Candidate 1 Released](http://weblog.rubyonrails.org/2014/11/28/Rails-4-2-0-rc1-has-been-released/)The [release notes](http://edgeguides.rubyonrails.org/4_2_release_notes.html) highlight the key features. Even the preview builds have felt solid to me. This release marks the beginning of Rails 5 dev too, as 4.2 becomes the last 4.x stable branch.
