Server Releases¶
Important
Support for Mattermost Server v10.5 Extended Support Release has come to the end of its life cycle on November 15, 2025. Upgrading to Mattermost Server v10.11 or later is required.
Upgrading from one Extended Support Release (ESR) to the next ESR (
major->major_next) is fully supported and tested. However, upgrading across multiple ESR versions (majortomajor+2) is supported, but not tested. If you plan to skip versions, we strongly recommend upgrading only between ESR releases. For example, if you’re upgrading from v8.1 ESR, upgrade to the v9.5 ESR or the v9.11 ESR before attempting to upgrade to the v10.5 ESR or the v10.11 ESR.See the Important Upgrade Notes documentation for details on upgrading to a newer release.
See the changelog in progress for details about the upcoming release.
All Mattermost users must accept Mattermost’s Acceptable Use Policy and Privacy Policy when creating an account or accessing Mattermost. For customers with a Mattermost subscription, including self-hosted deployments, organizations may replace or override the Acceptable Use Policy in the Mattermost System Console with their own acceptable use or conduct policies, based on contractual terms with Mattermost, so long as your own terms either incorporate the Acceptable Use Policy or include equivalent terms. If you change the default link to add your own terms for using the service you provide, your new terms must include a link to the default terms so end users are aware of the Mattermost Acceptable Use Policy for Mattermost software.
Frequency¶
Mattermost releases a new server version on the 16th of each month in binary form.
See the v11 changelog for details on what’s coming and changing in the next major release.
See the unsupported Mattermost legacy releases documentation for details on older, unsupported Mattermost releases.
