using the "latest" tag seems inefficient as it doesn't actually redirect to the latest release
In any case, the latest release is now 1.2.1
docker pull matrixdotorg/mjolnir:v1.2.1
Until now, we were leaving services "enabled"
(symlinks in /etc/systemd/system/multi-user.target.wants/).
We clean these up now. Broken symlinks may still exist in older
installations that enabled/disabled services. We're not taking care
to fix these up. It's just a cosmetic defect anyway.
