Update -- since Roy is out I am trying to sync up with @yliaog on this, who I pinged on Slack.

@yliaog @roycaihw @scottilee @palnabarun -- Any update on getting a release for this --> #1088?
Kubernetes 1.18.0 is being released today, which means 1.15 will no longer be supported very soon.

[yliaog]

i think @scottilee is working on it, any update @scottilee ?

[palnabarun]

@justaugustus The release of a v1.16 based client should be done soon.

@scottilee Let us know if you are blocked on anything.

[scottilee]

Yep, I'll take a look tonight and tomorrow.
