+* Kernel
+
+    * `Kernel#inspect` now checks for the existence of a `#instance_variables_to_inspect` method,
+      allowing control over which instance variables are displayed in the `#inspect` string:
+
+      ```ruby
+      class DatabaseConfig
+        def initialize(host, user, password)
+          @host = host
+          @user = user
+          @password = password
+        end
+
+        private def instance_variables_to_inspect = [:@host, :@user]
+      end
+
+      conf = DatabaseConfig.new("localhost", "root", "hunter2")
+      conf.inspect #=> #<DatabaseConfig:0x0000000104def350 @host="localhost", @user="root">
+      ```

     * `Binding#local_variables` does no longer include numbered parameters.
