Sorry for the drive-by comment, @slevenick will be the primary reviewer for this. I think release channels are gone GA: https://cloud.google.com/kubernetes-engine/docs/release-notes#september_16_2019

[chrissng]

Hello @rileykarson, the release channel config is currently only available in the v1beta1 GKE REST API. I will keep track and use v1 when it becomes available.

CI is failing due to this branch needing the vendored changes from your other branch. I'll cherry-pick and run tests manually, and if they work I'll go ahead and merge both PRs

Looks good, thanks for the addition!

Would be good to update this when the fields are available in the GA client

Ran into some issues during merging. Our git system doesn't function well if you merge master into your branch during development (each commit must be able to be applied to current master individually). I rebased on master and force pushed, but the diff should be identical (hopefully) and not create any downstreams

I'll merge assuming it all works and passes CI
