Upgraded my Pleroma to version 2.9.0, that came just out today. Or actually yesterday by now, because it took longer than expected. Maybe I missed some versions, but for me the upgrade was not as simple as suggested.

In this version I also needed to upgrade to a newer Elixir version. And there were also some migrations still to run. Upgrading Elixir turned out to not be possible on an old Debian server, so I needed to switch over to using asdf to get the newer version; but that doesn't work nicely with the systemd service file... I have to figure a better solution for that later, it is late, now I have just hardcoded the paths.
