I am targeting to approve #19451 today, and merge it later today or early tomorrow.

So we should be ready to release rc.1 early next week.

If we have #19461 ready by Tuesday, I was thinking of doing this along with 3.4.36. Or should we aim to do them one day apart?

OK to me. So it's Feb 25 (Tuesday)?
