+## What's new in v1.0.4
+
+### Clickable notifications
+Notifications are now interactive — tap to act, not just read:
+
+- **Limit warnings & resets** (80%, 95%, reset) — tapping the notification opens the main ClaudeChecker window so you can see your current usage at a glance
+- **Update available** — tapping the notification opens the main window with the update sheet already showing, so you can install in one click
+
+Previously notifications were display-only and required manually clicking the menubar icon to take action. This removes that friction.
