Only question is whether there will be updated config files for the Docker images. We have examples of those in the documentation too, so those may also need to be updated.

There won't be any updated configuration files as far as I'm aware.
But thanks for pointing out the docker doc.

It should probably also be mentioned in the note box here https://developer.concordium.software/en/mainnet/net/guides/run-node.html talking about the collector.
