Unreleased

Changelog
Mock auth.Auth.onIdTokenChanged() method, matching the previous behavior of onAuthStateChanged() (see below)
Support for Firebase Messaging (Admin API)
Support for FieldValue.increment
Support for firestore.Timestamp.now()
Support for listCollections in DocumentReferences

(Breaking) Consistent with Firebase SDK version 4.0.0 and later, and later, onAuthStateChanged no longer issues an event when a new ID token is issued for the same user. The onIdTokenChanged method is now mocked, keeping the previous behavior.
MockStorageFile.download() now allows omitting the destination arg; in that case, it simply resolves the Promise with the file contents and does not write it anywhere else.

onAuthStateChanged now correctly calls its callback immediately with the current auth state.
MockStorage.bucket() and MockStorageBucket.file() now return the existing artifact if one exists, rather than overwriting it with a new one.
DataSnapshot.child now correctly splits child paths by '/' characters
Boolean values are now allowed in RTDB priority fields and as arguments to Query.startAt, Query.endAt, and Query.equalTo.
MockFirestoreDocument.create() now correctly returns a Promise<WriteResult> instead of Promise<void>.
