_version is a required field

[alexandrapanas]

After the update from v.3 to the latest version _version field of all interfaces is required which messes up with our set up. There have already been an issue with _version before #65 which was fixed by making it optional. Is it possible to make it optional again?

Thank you for bringing this up. We’ve addressed this in v4.1.0, where the _version field is now optional again. Please update to the latest version and let us know if you face any further issues.
