How to discover which Spilo version contains which Patroni version?

[sgielen]

I'm trying to find out which Zalando k8s Postgres operator matches (by default) to which Patroni version.

For the Postgres operator, all releases contain a default Spilo version. The Spilo images on Docker Hub contain a version of Patroni.

Until Spilo 3.0-p1, it was documented which version that was. But since then, there have been Spilo releases and they are mentioned on the Postgres operator page, but I can't find a way to map those image versions to Patroni versions. I found this comment saying it makes no sense because nothing is pinned - but the images on Docker Hub do contain a Patroni version, don't they? Is there currently a way, other than running them all, to find out which is which?
