+// This file was removed in Mirror 3.4.9
+// The purpose of this file is to get the old file overwritten
+// when users update from the asset store to prevent a flood of errors
+// from having the old file still in the project as a straggler.
+// This file will be dropped from the Asset Store package in May 2019
