Upgraded zod to v4, replacing the deprecated zod-to-json-schema dependency with zod v4's built-in z.toJSONSchema(). Fixed an intermittent "Premature close" error during login and API requests, and switched cloudbilling API calls to user project quota to avoid shared quota exhaustion.
Firebase SQL Connect receives improvements, and Cloud Messaging gains new features.
Fixed various issues with the Data Connect emulator and deployment by updating the binary to version 3.4.13. Temporarily pinned the firebase-docker-image to Node 24.16.0 to mitigate a Node.js issue.
Analytics now supports measuring in-app purchases in Unity.
Added apphosting:secrets:revokeaccess command for managing secret access. Fixed non-deterministic output order of Data Connect generated SDK files from multiple GQL sources and optimized singular relation filters on primary keys.
Fixed a bug where Cloud Run rewrites in the Hosting emulator hit the live API instead of the local functions emulator. Added mock WebAuthn support to the Auth emulator, and fixed missing subcommands in firebase --help, Windows Python activation errors, and Astro 6 SSR 500 errors. Functions can now declare additional API dependencies.
Multiple Firebase SDK updates released:
Flutter SDK (v4.16.0): Changes in Cloud Firestore, Firebase AI Logic, App Check, Core and Cloud Messaging...
GeminiLanguageModel rename was applied then reverted back to GeminiModel. App Check gains a new RecaptchaEnterpriseProvider, a new internal default provider, and helpful debug token logging. Firestore removes designated initializers for force_index, and AI SDK handles an Xcode 27 LanguageModelSession.Error collision.
initializeAppCheck can now be called without a provider — it will auto-configure with ReCAPTCHA Enterprise using a site key from Firebase project config. Fixed a conflict error when both Auth and App Check used ReCAPTCHA Enterprise.
Removed the prompt and backend deletion of Data Connect services during firebase deploy. Fixed firebase init dataconnect failing with ENOEXEC when creating a new template app. Also added support for setting the Google Cloud Storage test results bucket in apptesting:execute and appdistribution:distribute.
