Outdated with major recommended protocol change local=v6.0.0 required=v7.0.0 recommended=v7.0.0

Won't sync; geth exits with "Outdated with major recommended protocol change local=v6.0.0 required=v7.0.0 recommended=v7.0.0"... I think I followed the instructions to a T.

geth logs:

./geth-data dir contains very recent (2 days ago) snapshot base-mainnet-full-1720420879.tar.zst

What is this change from 6.0.0 to 7.0.0? Where is my misconfiguration?

[webhype]

What is odd is that the logs show geth-1 and not execution-1. There was a prior installation at that exact place where it was still called geth, not execution. Could it be a docker cache / image that doesn't get fully rebuilt based on the new docker-compose.yml? I made a fresh directory every time but who knows any more what Docker really does? Will investigate in that direction...
