Are new versions of Node-Exporter for Prometheus compatible to older versions? Is someone automatically update this exporter without any check's?

node_exporter is still pre-1.0.0 so metrics and/or CLI flags may change between versions.  Read the release notes.

Technically, node_exporter is still pre-1.0 (1.0 is on its way, there is
a first RC), so there are no hard guarantees. In practice, there was
only one major change in recent times I can remember. It was related to
counter renames.

I would suggest reading the changelog, which denotes breaking changes,
and maybe running a diff between the old and the new output.

Kind regards,
Christian
