Posted by k0kubun on 14 Jul 2026

      <p>Ruby 4.0.6 has been released.</p>

This is a routine update that includes bugfixes. Please see the GitHub releases for further details.

Release Schedule

We intend to release the latest stable Ruby version (currently Ruby 4.0) every two months following the most recent release. Ruby 4.0.7 will be released in September, and 4.0.8 in November.

If a change arises that significantly affects users, a release may occur earlier than planned, and the subsequent schedule may shift accordingly.
