Release Lifecycle
Available on all plans
self-hosted deployments
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 v6.3 Extended Support Release has come to the end of its life cycle on October 15, 2022. Upgrading to Mattermost Server v7.1 or later is required.

Desktop and mobile app compatibility
Mattermost desktop and mobile apps are backwards compatible; however, we strongly recommend updating to the latest version for an optimal user experience. The latest versions include the latest security fixes, and are compatible with the oldest supported extended support release of Mattermost Server to ensure backwards compatibility.
Please review the desktop app changelog and the mobile app changelog notes for any self-hosted or Cloud-specific version requirements for features and functionalities, as well as notes on security fixes.
Notes on Upgrading to Mattermost v6.0 or later
Upgrading Mattermost desktop and mobile apps to the latest version is not mandatory when upgrading to Mattermost Server v6.0. Earlier 4.x versions of Mattermost desktop app, and earlier v1.x versions of the mobile app, will continue to be supported with a Mattermost v6.0 Server.
