Mattermost backports high-severity or high-impact security fixes to the previous three monthly releases and to supported extended support releases (ESR). A new ESR release is made when a significant number of new features and improvements have been added to the product, and have had sufficient time to stabilize. A new ESR is released twice a year in January and July. ESR releases are supported for nine months.

Announcements are published on the Mattermost Announcements Mailing List.

More information is available on the Mattermost website.

You should be running one of the supported release numbers listed above in the rightmost column.
