+# Task: Frontend What’s New experience
+
+## Goal
+
+Add the user-facing What’s New experience for published release updates and unread state.
+
+## Feature Spec
+
+- `docs/FEATURES/release-communications.md`
+
+## Scope
+
+- Add feature-owned frontend code under `frontend/src/features/release-communications/`.
+- Add `/app/updates`.
+- Add an app shell entry or badge for unread release updates.
+- Fetch visible published release updates from the backend.
+- Show unread state for update entries.
+- Mark an update as read when opened.
+- Add a mark-all-read action.
+- Optionally show a non-blocking login-time What’s New panel when unread updates exist.
+- Add English and French locale strings.
+- Keep developer authoring UI, commit reconciliation, and email digest out of this task.
+
+## Likely Files
+
+- `frontend/src/router/router.js`
+- `frontend/src/layouts/main/**`
+- `frontend/src/features/release-communications/**`
+- `frontend/src/locales/en.json`
+- `frontend/src/locales/fr.json`
+
+## Notes
+
+- The user-facing update feed must be curated and should not show raw commit SHAs, commit subjects, branch names, or internal-only work.
+- Keep the UI compact and app-like. This is an operational app surface, not a marketing release notes page.
+- Use the shared Axios API client in `frontend/src/plugins/api.js`.
+
+## Validation
+
+```bash
+cd frontend
+npm run build
+```
+
