+*v0.21.0*
+
+- bigquery:
+  - Add OpenCensus tracing.
+
+- firestore:
+  - **BREAKING CHANGE:** If a document does not exist, return a DocumentSnapshot
+    whose Exists method returns false. DocumentRef.Get and Transaction.Get
+    return the non-nil DocumentSnapshot in addition to a NotFound error.
+    **DocumentRef.GetAll and Transaction.GetAll return a non-nil
+    DocumentSnapshot instead of nil.**
+  - Add DocumentIterator.Stop. **Call Stop whenever you are done with a
+    DocumentIterator.**
+  - Added Query.Snapshots and DocumentRef.Snapshots, which provide realtime
+    notification of updates. See https://cloud.google.com/firestore/docs/query-data/listen.
+  - Canceling an RPC now always returns a grpc.Status with codes.Canceled.
+
+- spanner:
+  - Add `CommitTimestamp`, which supports inserting the commit timestamp of a
+    transaction into a column.
