Release Lifecycle

What is a Release Lifecycle?

During each monthly release, Mattermost backports high severity or high impact security fixes to the previous three monthly releases. Extended Support Releases receive backports for security fixes and major bug fixes for the length of their life cycle. Once a release life cycle has ended, it will no longer receive the security or major bug backports. We follow the same release cycle pattern for all upcoming releases.

Important

Support for Mattermost Server v5.31 Extended Support Release will come to the end of its life cycle on October 15, 2021. Upgrading to Mattermost Server v5.37 or later is required.
