Generally, we have aimed for quarterly releases but that schedule hasn't always been strictly followed.

By the way, I noticed there's a minor issue (#6791) that needs to be resolved before moving forward with this PR

Thanks, i was trying to figure out why it was not updating that file.

@tsaarni I used your changes in #6791 to generate the deepcopy file and updated the types in the tests. I think it should pass the CI tests now as it passes the tests locally.
