Summary

This release introduces new APIs for FCM registration and on-device model initialization, promotes hybrid inference features to public status, and includes numerous bug fixes across Firestore, Messaging, and App Check.

Migration Steps

  1. Use the new API for creating and deleting FCM registration in @firebase/messaging instead of the old API.

✨ New Features

  • Added initializeDeviceModel() method to @firebase/ai and firebase to allow explicit initialization of on-device model in hybrid mode.
  • Hybrid inference features tags changed from "beta" (public preview) to "public" (generally available) across @firebase/ai and firebase.
  • Added minimum and maximum FieldValue operations in @firebase/firestore and firebase.
  • Added new API for creating and deleting FCM registration in @firebase/messaging.

🐛 Bug Fixes

  • Fixed a bug in @firebase/ai where ChatSession.sendMessageStream() and TemplateChatSession.sendMessageStream() sent duplicate user turns in the request.
  • Updated _isAvailable() in @firebase/auth and @firebase/auth-compat to use retry logic for the initial IndexedDB availability check, preventing incorrect fallbacks to in-memory persistence.
  • Improved robustness and logging in query listen stream creation and re-creation in @firebase/firestore.
  • Fixed delivery metrics Firelog flushing when BigQuery export is enabled in @firebase/messaging by adjusting flush scheduling and processing logic.
  • Fixed a bug in @firebase/app-check where getLimitedUseToken() did not correctly get a limited use token because it did not send the limited_use param.
