No more new builds for Windows 10

Unfortunately it's confirmed: https://blogs.windows.com/windows-i...ows-10-insider-preview-build-19044-1147-21h2/

Windows 10 21H2 will be just a maintenance release, with the build number 19044. Of course, this build is not workable on M1. So Windows 10 build 21390 from the dev channel is the last build of Windows 10. All further development is switched to Windows 11.
