Please try to use

For docker nodes
Like last time we would like the docker nodes to test out the new image early ( bfc3d4c9d-v1.52.2-go1.17.5 ). The reason for this is that we switched to a different base image. That should fix most of the bugs we have seen last time. We are especially interested in arm32 nodes but also all other architectures.

If it would work - left the message in this thread: Changelog v1.52.2
When it would be tested - we will push the latest image and you can switch back to the latest too.
