There are tagged images available on Docker Hub which correspond to software releases seen in the changelog. The docker tag master is the latest development release. A generic major version tag is available, representing the latest release on a given major version. For example, the v3.x.x tag represents the most current release for the v3.x.x release line. You can utilize specific tagged versions, or a major version specifier, depending on your chosen deployment strategy.
