Release Notes

3.3.11

Posted by hsbt on 26 Mar 2026

      <p>Ruby 3.3.11 has been released. This release includes <a href="https://www.ruby-lang.org/en/news/2026/03/05/buffer-overflow-zlib-cve-2026-27820/">an update to the zlib gem addressing CVE-2026-27820</a>, along with some bug fixes.</p>

Please see the GitHub releases for further details.

This is the last release of normal maintenance for the Ruby 3.3 series. After this release, Ruby 3.3 enters a security maintenance phase. During this phase, we will only backport security fixes and fixes for critical build issues, without any regular bug fixes.

The security maintenance phase is scheduled to last for one year, until the end of March 2027. At that point, official support for Ruby 3.3 will end. We recommend that you begin planning your migration to Ruby 3.4 or 4.0.
