Upgrade ES from 7.6 to 7.6.1

I would like to add an extra local node to my ES cluster.
At the moment I am running a single node instance (version 7.6.0) and I was wondering whether I can add an extra node running 7.6.1 to the same cluster (which is comprised of the aforementioned node running 7.6.0).
Otherwise, how can I upgrade my current cluster to 7.6.1? In the upgrade page, there is no option for upgrades within the same macro-version. The most recent section is from 7.0-7.5 to 7.6.
Thank you

No, you shouldn't plan to have a mixed-version cluster, except for a short period during a rolling upgrade.

But you raise a good point that the docs do not cover upgrades for patch releases. You can upgrade from 7.6.0 to 7.6.1 just as for minor version upgrades, so treat it like 7.5.0 to 7.6.1 for the purposes of those docs. I opened an issue to get that fixed:
