Authentication

• Fixed a bug on iOS causing incorrectly formatted links to be sent in emails. See GitHub issue #5541 .

Authentication

All browser persistence implementations such as indexedDBLocalPersistence are mapped to inMemoryPersistence in Node.js to allow isomorphic code that works well with use cases like server-side rendering.

emailVerified field is now set in the User correctly. See GitHub issue #5430 .

Added missing phone FACTOR_ID static property to the PhoneMultiFactorGenerator class. See GitHub issue #5480 .

Fixed wrongly-typed tenantId fields in requests to some endpoints.

Cloud Firestore

• Fixed a bug where UpdateData did not recognize union types or optional, dot-separated string fields.

Remote Config

• Added an isSupported() function. You can use this function to check if the current environment supports Remote Config , and only initialize Remote Config in supported environments.

Analytics

• Fixed an issue where isSupported() throws unexpected errors in certain environments.

App Check

Initialization no longer throws runtime errors in Node.js.

Debug mode check is delayed till initializeAppCheck() is called.

Cloud Messaging

• Fixed an issue where isSupported() throws unexpected errors in certain environments.

Performance Monitoring

• Fixed an issue where isSupported() throws unexpected errors in certain environments.

Testing SDK

Fixed typing issues where Database / Firestore / Storage compat instances returned by RulesTestContext are not compatible with v9 modular APIs.

Set RTDB namespace to be same as projectId by default instead of ${projectId}-default-rtdb . This fixes rules not being applied and other issues related to namespace mismatch.

Authentication

Fixed a bug where custom errors from blocking functions were being dropped. See GitHub issue #5386 .

Removed const enum s from the public typings file.

Cloud Firestore

Improved the error handling when the SDK encounters a failure opening IndexedDB in a Firefox private browsing session. See GitHub issue #5377 .

Fixed a deadlock during asynchronous initialization of both Cloud Firestore and Authentication . See GitHub issue #5402 .

Fixed the behavior of collection() when passed multiple path segment strings. See GitHub issue #5431 .

Added a temporary workaround for a bug causing initializeFirestore() to throw errors when used in certain build pipelines, such as the default production build for Create React App. See GitHub issue #5384 .

Cloud Functions for Firebase Client SDK

• The SDK now omits sending an App Check token header to the Cloud Functions endpoint if there is no valid App Check token to send.

Cloud Storage

• Fixed a bug that incorrectly threw an error when using refFromUrl() with connectStorageEmulator() . See Github issue #3715 in firebase-tools .
