Good idea. I’m using the latest version of the reconciliation service you originated (NFDI4Culture / TA1 data enrichment / OpenRefine Wikibase · GitLab) and it only works on 3.7 (at least when reconciling against wikibase.cloud). So that’s a good reason to get the beta out there.
Looks like there isn’t anything in the way anymore, then.
I will make the release in a few days (sadly I did not write the changelog as PRs were merged so I will first have to catch up on that).
