What's New is a custom Experience Builder 1.20 widget that adds the familiar bell-and-red-dot notification pattern to public-facing map applications. It drops into any spot of an Experience (header, body, or footer) and displays a small red dot whenever there's a new announcement. Users click the bell, see what changed in a popover or centered modal, and the dot disappears for them across browser sessions. When the next update goes out, bumping the Announcement ID (a "New ID" button in the settings panel drops in a timestamp) brings the dot back for everyone on their next visit. Content is either Rich HTML pasted directly into the settings or an external URL, and the widget is pure client-side with no backend. Seen-state lives in each user's localStorage, so there's nothing to maintain. The widget solves a recurring problem: every time improvements are pushed to an Experience, users have no idea anything changed because they tend to bookmark the map and use it the same way for months. What's New gives them a quiet, dismissible signal built right into the app.
