Announcing Windows 10 Insider Preview Build 21354

Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 21354 to Windows Insiders in the Dev Channel.

Starting with today’s build, Windows Insiders will notice that the name of the branch we are releasing builds as shown on the desktop watermark at the lower right of the desktop from has changed to CO_RELEASE. Just like we did back in October when we released builds from the FE_RELEASE branch, we are practicing our ability to change which branch flight builds from. As our engineers work in development cycles internally, we may prioritize work being done in a specific branch and may need to move Insiders between branches. We are treating these builds the same as we would treat builds from the RS_PRERELEASE branch.
