+  - Notification routing by app state (active/background/closed)
+  - Rich push presentation via `CampaignViewController` WebView (campaign URL built from `session_uuid`)
+  - Push analytics events (`NB_PushReceived` and `NB_PushAck`)
+  - Custom push handler protocol (`WarplyPushHandler`) for non-standard action codes
+  - Pending notification queue for cold-start handling (`handleLaunchOptions()`, `handlePendingNotification()`)
+  - Badge management via `resetBadge()`
+  - Comprehensive device info sending to server
+  - New `PushNotificationReceivedEvent` and `PushNotificationEngagedEvent` in EventDispatcher
+  - Convenience wrappers for `UNUserNotificationCenterDelegate` methods (host app forwards calls to SDK)

+- **retrieveCoupon Functionality Added**: New `retrieveCoupon` method for redeeming/retrieving coupons from coupon sets programmatically.
