Firebase Admin Python SDK v2.16.0

• Added generate_password_reset_link(), generate_email_verification_link() and generate_sign_in_with_email_link() methods to the auth API.
• Migrated the auth user management API to the new Identity Toolkit endpoint.
• Extending HTTP retries to more HTTP methods like POST and PATCH.

Firebase Admin Python SDK v2.15.1

• Implemented HTTP retries. The SDK now retries HTTP calls on low-level connection and socket read errors, as well as HTTP 500 and 503 errors.

Firebase Admin Python SDK v2.15.0

• Dropped support for Python 3.3. Developers on Python 3 must use 3.4 or higher. Support for Python 2.7 has not changed.
• Declared a direct dependency on google-api-core[grpc] in order to resolve some long-standing Firestore installation problems.

Firebase Cloud Messaging

• The messaging.Aps class now supports configuring a critical alert sound. A new messaging.CriticalSound class has been introduced for this purpose.
• messaging.WebpushConfig class now supports configuring additional FCM options for the features supported by the Firebase web SDK. A new messaging.WebpushFcmOptions class has been introduced for this purpose.

Firebase Admin Python SDK v2.14.0

• A new project_management API for managing apps in a Firebase project.
• New list_android_apps() and list_ios_apps() methods for listing the existing apps in a project.
• New create_android_app() and create_ios_app() methods for creating new apps in a project.
• New AndroidApp and IosApp APIs for updating individual apps.

Realtime Datbase

• Fixed a performance issue in the db.listen() API where it was taking a long time to process large RTDB nodes.
• Fixed how the SDK handles special characters in node names.

Cloud Messaging

• messaging.AndroidNotification type now supports specifying a channel_id when sending messages to Android O devices. Thanks chemidy for the contribution
• Improved error handling by requesting a more verbose error response from the FCM backend service.

Authentication

• Fixed the property UserRecord.tokens_valid_after_time so that it always returns an integer, and never returns None.

Firebase Admin Python SDK v2.13.0

Database

• The db.Reference type now provides a listen() API for receiving realtime update events from the Firebase Database. Thanks the-c0d3r and rizasif for the contributions.
• The db.reference() method now optionally takes a URL parameter. This can be used to access multiple Firebase Realtime Database instances in the same project more easily.

Cloud Messaging

• The messaging.WebpushNotification type now supports additional parameters.

Firebase Admin Python SDK v2.12.0

• The Admin SDK can now read the Firebase/Google Cloud Platform project ID from both GCLOUD_PROJECT and GOOGLE_CLOUD_PROJECT environment variables.

Authentication

• The Admin SDK can now create custom tokens without being initialized with service account credentials.
• The SDK now accepts a serviceAccountId app option, which can be used to set just the client email of a service account.
• When deployed in an environment managed by Google (e.g. Google App Engine), the SDK can auto discover a service account ID without any explicit configuration.

Firebase Admin Python SDK v2.11.0

• [added] A new auth.import_users() API for importing users into Firebase Auth in bulk.
• [fixed] The db.Reference.update() function now accepts dictionaries with None values. This can be used to delete child keys from a reference.

Firebase Admin Python SDK v2.10.0

Authentication

• A new create_session_cookie() method for creating a session cookie from a Firebase ID token.
• A new verify_session_cookie() method for validating a given session cookie string.
• The auth module now caches the public key certificates used to verify ID tokens and session cookies, thus avoiding a network call everytime a credential needs to be verified.

Cloud Messaging

• Added the mutable_content optional field to the messaging.Aps type. This can be used to set the mutable-content property when sending FCM messages to APNs targets.
• Added support for specifying arbitrary key-value fields in the messaging.Aps type.

Firebase Admin Python SDK v2.9.1

Cloud Messaging

• [changed] Improved error handling in FCM by mapping more server-side
  errors to client-side error codes. See documentation.
• [changed] The messaging module now supports specifying an HTTP timeout
  for all egress requests. Pass the httpTimeout option
  to firebase_admin.initialize_app() before invoking any functions in
  messaging.

Firebase Admin Python SDK v2.9.0

Firebase Cloud Messaging

• A new firebase_admin.messaging
  module for sending messaging messages and managing topic subscriptions.
• A new send()
  function for sending messaging messages.
• A new subscribe_to_topic()
  function for subscribing a list of device registration tokens to a
  messaging topic.
• A new unsubscribe_from_topic()
  function for unsubscribing a list of device registration tokens from a
  messaging topic.

Firebase Auth

• 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.
• A new revoke_refresh_tokens()
  function to invalidate all tokens issued to a user.
• A new tokens_valid_after_timestamp property has been added to the
  UserRecord
  class to indicate the time before which tokens are not valid.
