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 has come to the end of its life cycle as of October 15, 2021. Upgrading to Mattermost Server v5.37 or later is required.

Desktop and Mobile App Server Compatibility
Mattermost Desktop and Mobile Apps must be used with the latest Extended Support Release or a newer version of Mattermost Server.
Upgrading to Mattermost v6.0
For an optimal user experience, we strongly recommend upgrading both your Mattermost Desktop and Mobile Apps to the latest version. 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.
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.
In cases where Mattermost features or functionality involve the operating system, a specific Desktop App or Mobile App version may be required. For example, the Mattermost Desktop App v4.6 includes a setting for choosing desktop notification sounds which requires Mattermost Server v5.28 or later.
Note
Bug fixes aren’t typically backported to previous Desktop App or Mobile App versions. Upgrading to the latest Desktop and Mobile App versions helps you stay updated with the latest bug and security fixes.
