After expecting to put out a release candidate Tuesday of Ruby on Rails 3.0, the latest major upgrade to the popular Web development framework, developers of Rails instead decided to put out a fourth beta version and wait until the end of the week for the release candidate.
Usually the last phase before a general release, a release candidate “was the original plan, [but] last-minute, we decided to call it another beta and give it a few more days,” said David Heinemeier Hansson, founder of Rails, on Tuesday evening.
