Microsoft today released a new build to Insiders in the Beta channel. The released Build 19043.899 represents the nearly coming Windows 10 version 21H1, a minor feature update to existing 2004 and 20H2 releases.
Today's release is out as a cumulative update KB5000842. It doesn't include new features. That's because despite being a minor update, Windows 10 version 21H1 is already feature complete. Microsoft is only polishing minor issues found in this branch of the OS.
