Needed for oscar-system/Oscar.jl#5151

[simonbrandhorst]

Maybe the release could wait for / include
#2098 . That will be needed as well soon.

[thofma]

Sure

[lgoettgens]

It would be great if we could release this soon-ish to allow proceeding with #2095. If #2098 is basically finished, that's fine for me. But if it needs some further work, I would prefer having a release now and then another one in a few days (e.g. once #2098 is merged).

[simonbrandhorst]

It is finished and merged.
