We should probably implement deprecation warnings in the code. We have changed a few class names recently and we have code in place for compatibility. E.g. canopen.sdo.base defines Record as alias to SdoRecord and so on. I agree that we must not introduce breaking change and have aliases like this, but I think we should inform them as deprecated so we steer the users towards the new API.

We should also write a statement when these aliases will stop working.
