Hit the update button, because you can’t proceed without docker_manager being up to date.
I’m not sure how docker_manager is versioned, tbh, but showing a commit hash would seem completely reasonable.
If you want a “slower” set of updates, you can switch to stable branch in app.yml and wait for the new 3.3.0 stable to be cut (which may be quite soon 
) and then rebuild (from the command line)
