 * [changed] Replaced java.util.Date with
   com.google.firebase.dataconnect.LocalDate.
   ([#6434](https://github.com/firebase/firebase-android-sdk/pull/6434))
+* [changed] `DateSerializer` removed, as it is superceded by
+  `LocalDateSerializer`. As of Data Connect emulator version 1.7.0, the
+  generated Kotlin code uses `com.google.firebase.dataconnect.LocalDate`
+  instead of `java.util.Date`. Therefore, this version of the SDK must be
+  paired with code generated by version 1.7.0 (or later) of the Data Connect
+  emulator.
+  ([#6513](https://github.com/firebase/firebase-android-sdk/pull/6513))
 
 # 16.0.0-beta02
 * [changed] Updated protobuf dependency to `3.25.5` to fix
