If I install croc via the install-script it should check before sending/receiving if it is up to date so I don't get any errors because the server was updated

I'd accept a PR for this

Sadly I can't code Go

How should croc discover latest release? From github API? I think it should be optional parameter as doing another call to github API can be considered harmful.

Yea, but I mean, for example, croc receives an update, but the client throws an error because the client and the server are incompatible. I would like to see something like you client isn't up-to date. Please update croc. instead of an error Nobody understands.

I think it would be suitable for the relay to notify the user about this.
