Unreleased

[changed] Improved error handling in FCM by mapping more server-side errors to client-side error codes.

v2.9.0

Cloud Messaging

[feature] Added the firebase_admin.messaging module for sending Firebase notifications and managing topic subscriptions.

Authentication

[added] The 'verify_id_token()' function now accepts an optional check_revoked parameter. When True, an additional check is performed to see whether the token has been revoked.
[added] A new 'auth.revoke_refresh_tokens(uid)' function has been added to invalidate all tokens issued to a user.
[added] A new tokens_valid_after_timestamp property has been added to the
'UserRecord', class indicating the time before which tokens are not valid.

v2.8.0

Initialization

[added] The initialize_app() method can now be invoked without any arguments. This initializes an app using Google Application Default Credentials, and other options loaded from the FIREBASE_CONFIG environment variable.

Realtime Database

[added] The db.Reference.get() method now accepts an optional shallow argument. If set to True this causes the SDK to execute a shallow read, which does not retrieve the child node values of the current reference.

v2.7.0

[added] A new instance_id API that facilitates deleting instance IDs and associated user data from Firebase projects.

v2.6.0

Authentication

[added] Added the list_users() function to the firebase_admin.auth module. This function enables listing or iterating over all user accounts in a Firebase project.
[added] Added the set_custom_user_claims() function to the firebase_admin.auth module. This function enables setting custom claims on a Firebase user. The custom claims can be accessed via that user's ID token.

Realtime Database

[changed] Updated the start_at(), end_at() and equal_to() methods of the db.Query class so they can accept empty string arguments.

v2.5.0

[added] A new Firestore API that enables access to Cloud Firestore databases.

v2.4.0

Realtime Database

[added] The db.Reference class now has a get_if_changed() method, which retrieves a database value only if the value has changed since last read.
[added] The options dictionary passed to initialize_app() function can now contain an httpTimeout option, which sets the timeout (in seconds) for outbound HTTP connections started by the SDK.

v2.3.0

Realtime Database

[added] You can now get the ETag value of a database reference by passing etag=True to the get() method of a db.Reference object.
[added] The db.Reference class now has a set_if_unchanged() method, which you can use to write to a database location only when the location has the ETag value you specify.
[changed] Fixed an issue with the transaction() method that prevented you from updating scalar values in a transaction.

v2.2.0

[added] A new Cloud Storage API that facilitates accessing Google Cloud Storage buckets using the google-cloud-storage library.

Authentication

[added] A new user management API that allows provisioning and managing Firebase users from Python applications. This API adds get_user(), get_user_by_email(), get_user_by_phone_number(), create_user(), update_user() and delete_dser() methods to the firebase_admin.auth module.

Realtime Database

[added] The db.Reference class now exposes a transaction() method, which can be used to execute atomic updates on database references.

v2.1.1

[changed] Constructors of Certificate and RefreshToken credential types can now be invoked with either a file path or a parsed JSON object. This facilitates the consumption of service account credentials and refresh token credentials from sources other than the local file system.
[changed] Better integration with the google-auth library for making authenticated HTTP requests from the SDK.

v2.1.0

[added] A new database API that facilitates basic data manipulation operations (create, read, update and delete), and advanced queries. Currently, this API does not support realtime event listeners. See Add the Firebase Admin SDK to your Server to get started.

v2.0.0

[changed] This SDK has been migrated from oauth2client to the new google-auth library.

Authentication

[changed] This SDK now supports verifying ID tokens when initialized with application default credentials.

v1.0.0

[added] Initial release of the Admin Python SDK. See Add the Firebase Admin SDK to your Server to get started.

Initialization

[added] Implemented the firebase_admin module, which provides the initialize_app() function for initializing the SDK with a credential.
[added] Implemented the firebase_admin.credentials module, which contains constructors for Certificate, ApplicationDefault and RefreshToken credential types.

Authentication

[added] Implemented the firebase_admin.auth module, which provides create_custom_token() and verify_id_token() functions for minting custom authentication tokens and verifying Firebase ID tokens.
