Support of Ruby 2.1 has ended

Posted by usa on 1 Apr 2017

We announce that all support of the Ruby 2.1 series has ended.

After the release of Ruby 2.1.10 at the end of March of the last year, the support of the Ruby 2.1 series was in the security maintenance phase. Now, after one year has passed, this phase has ended. Therefore, at March 31, 2017, all support of the Ruby 2.1 series has ended. Bug and security fixes from more recent Ruby versions will no longer be backported to 2.1, and no further patch release of 2.1 will be released. We highly recommend that you upgrade to Ruby 2.4 or 2.3 as soon as possible.
