Version Compatibility when I am adding a new node to a cluster

[PythonTrader]

I have a Proxmox V8 cluster with two nodes.

I built the cluster 6 month ago.

I am planning to add one more node to my cluster.

Can I download the latest installation USB key and install the new node or there is a version compatibility requirement between a PVE cluster nodes?

Thank you

Same Major-Version should be fine. But you should still upgrade all of your nodes to the latest version unless you like unpatched bugs and vulnerabilities.
