Hi there!
I am about to update our controller & routers in K8s and I am wondering whether there are some version restrictions we need to adhere to, meaning should we also update other edge routers ziti binaries and/or ziti-edge-tunnelers (linux-based). Can you provide some insight here ?

At this time we are still recommending all overlay component versions be at the same level/number/version.
We expect this will change in the future, but when is not exactly known. Generally, most things would probably work fine but to be more certain, we still recommend keeping them aligned
Hi @TheLumberjack thank you for the response!
Can you provide an example to illustrate what that means for the ziti-edge-tunnel and windows tunneler ? 
Are they somehow related via the SDK version ?
Ah. Those are different. Those were guarantee backwards comparability expectations. Old tunnelers are expected to work with new networks. You originally mentioned what I consider the overlay network pieces which are different to me than the edge clients connecting to the overlay and I didn't see the rest of your message some how. 
.
So there's no need to upgrade those. We recommend you upgrade them but it should be fine if they're "older". The zdew (desktop edge for Windows) is set to automatically upgrade itself and a newer version of that is coming out relatively soon
no worries 
Ok thanks for the info!
