Windows 10 build 21376 is now available with a new font and other improvements May 6, 2021 13:12 EDT · Hot! with 13 comments Following on last week's release of build 21370, Microsoft is sticking to a Thursday release for this week's Windows 10 build in the Dev channel, build 21376. Like the past few releases, this one is from the co_release branch, which would usually indicate that Microsoft may be getting ready to wrap up development on the next feature update for Windows 10. This build is fairly light on news, but it does include a new Segoe UI Variable font, which is designed to scale better across different display sizes, specifically larger ones. The original Segoe UI font was designed to optimal at 9pt sizes, but this variant should adapt better to different displays.
