The XCM v3 release date at Kusama and Polkadot

Hi everyone!
Is there any specific date (or period) when the XCM v3 will land on Kusama and Polkadot?

It was merged into the main branch 2 weeks ago. So I’d expect it to be in the next release.

More importantly, what’s the testing plan to ensure all the existing XCM code still works after Kusama / Statemine upgrade?
