I must be honest... I did not, in fact, read every change in the 159000-line generated TypeScript file. I did do a random sample of the diffs, though, and they look fine, and I didn't see anything that looked wrong.

How do we release this? It is presumably a breaking change, so we probably need to do a full version rev. Do we need to backport it to older releases in order to support older versions of the k8s API?
