In the meantime, key changes mentioned on the Windows Insider blog include security updates to Windows App Platform and Frameworks, the Windows Kernel, Windows Media, the Microsoft Scripting Engine, and the Windows Silicon Platform.
Update: The release notes are now live and you can find the highlights below
- Updates to improve security when Windows performs basic operations.

As Windows 10 version 20H2 crossed 40% market share in April according to AdDuplex, Microsoft is expected to start rolling out Windows 10 version 21H1 later this month. This minor update will bring multiple camera support for Windows Hello as well as performance improvements for Windows Defender Application Guard, and it will install like a regular cumulative update.
Today also marks the end of support of Windows 10 version 1909 for Home and Pro users, who should now upgrade to a newer version of the OS. According to the Windows 10 Health Dashboard, Microsoft finally removed last week the last upgrade blocks preventing users with certain Conexant audio drivers to install Windows 10 version 2004 or 20H2.
