Hi @caugner! I created this release branch to be consistent with our other projects and serves to update the patches. The tag is updated here: https://github.com/mattermost/mattermost-docker/tags and appears here: https://hub.docker.com/r/mattermost/mattermost-prod-app/tags?page=1&ordering=last_updated

@metanerd Does this mean the version in the master Dockerfile will only get updated for minor versions in the future? In the past, master usually had the latest version number.

Alternatively, it might be useful to have a latest (or esr) branch that always has the latest released (or ESR) version. This makes it easier to automate updates by tracking one of these branches.
