Contributors, 

Please update your contact lists to d...@kubernetes.io (former: kuberne...@googlegroups.com). 

No other actions needed; your subscription cadence (digest, every email, abridged, no email) was migrated over, too. If you are no longer an aspiring or current contributor and would like to unsubscribe, send a note to: dev+uns...@kubernetes.io.

Happy emailing,

Paris, sig-contribex
