News and interests updates
Cards for each article have a new, more colorful design. In addition, icons for actions such as Like or Save are now inside translucid circles. These features are currently rolling out to a subset of Windows Insiders in the United States.

The expanded feed that shows up when clicking the Show more news link in the flyout has been heavily revamped, with an updated design like the one mentioned above and large cards showing article text.

The emojis used to react to an article have been updated on both the browser feed and the flyout.

Iconography improvements
A new font, Segoe Fluent Icons, has been added in this build, which updates many system icons in apps that previously used the Segoe MDL2 Assets to new rounded and simplified ones.

In this build, this new set of icons is only used in the Start menu and Windows Security's left panes, most of the Settings app, Magnifier, the touch keyboard, and some areas of the taskbar jump lists.

Other changes
