correct me if I'm wrong but just to clarify this 20xxx/21xxx branch is Iron, and the next major 21H2 branch is named cobalt right? If so, then -After the current 20H2, MSFT will be releasing the 21H1 by June-2021 via the EP & bumping the existing build from 19042.x to 19043.x, -And then release the cobalt 21H2 in Oct/Nov-2021. Then where does this Iron branch builds (20xxx/21xxx) that are currently being released under insider programme stands? This will be merged with 21h2 i.e. cobalt or what? P.S: The last thing I knew that all these Iron branches build (20xxx/21xxx) was meant for Windows 10X release.
