I see there's already another issue opened here: #1593
Can we close one of them?

[wlan0]

Could you please close the other one: #1593

Looks like john created that project before he left the group

Just confirming this is indeed for 1.21 not 1.20?

Thanks!

@kikisdeliveryservice,

Yes, we are targeting Alpha in 1.21. In 1.20, we are planning to get the KEP merged as Provisional status and coding will happen in repos under kubernetes-sigs. That's why we still have 1.20 as milestone for the KEP.

@xing-yang understood - thank you for the clarification! I'll update the sheet to reflect the alpha in 1.21 goal so we don't start pinging you for the 1.20 cycle on this issue 😄
