v4.0.0

Features

• Added support for phone number authentication using the following APIs:
  • PhoneAuthProvider
  • firebase.auth.Auth.prototype.signInWithPhoneNumber
  • firebase.User.prototype.linkWithPhoneNumber
  • firebase.User.prototype.reauthenticateWithPhoneNumber
• Augmented the IdP data (for a list of all supported fields see firebase.auth.UserCredential) returned by the following APIs:
  • firebase.auth.Auth.prototype.signInAndRetrieveDataWithCredential
  • firebase.User.prototype.linkAndRetrieveDataWithCredential
  • firebase.User.prototype.reauthenticateAndRetrieveDataWithCredential
• Added the firebase.auth.Auth.prototype.onIdTokenChanged method that triggers on ID token changes.

Breaking Changes

• firebase.auth.Auth.prototype.onAuthStateChanged now triggers on sign in and sign out.
• firebase.User.prototype.reauthenticate has been removed in favor of firebase.User.prototype.reauthenticateWithCredential.
• firebase.User.prototype.link has been removed in favor of firebase.User.prototype.linkWithCredential.
• firebase.AuthCredential.prototype.provider has been removed in favor of firebase.AuthCredential.prototype.providerId.

Deprecations

• Removed support for deprecated serviceAccount and credential properties from the Node.js SDK. If you were previously using the Firebase Javascript SDK to use these properties, use the Firebase Admin Node.js SDK instead.
• Deprecated firebase.User.prototype.getToken in favor of firebase.User.prototype.getIdToken.

Fixes

• Fixed an issue where firebase.User.prototype.updateProfile was not triggering an update in password provider data.
