     *Dmitriy Kiriyenko*
 
+*   Add ActiveSupport::Logger#silence that works the same as the old Logger#silence extension.
+
+    *DHH*
+
+*   Remove surrogate unicode character encoding from `ActiveSupport::JSON.encode`
+    The encoding scheme was broken for unicode characters outside the basic multilingual plane;
+    since json is assumed to be `UTF-8`, and we already force the encoding to `UTF-8`,
+    simply pass through the un-encoded characters.
+
+    *Brett Carter*
+
 *   Deprecate `Time.time_with_date_fallback`, `Time.utc_time` and `Time.local_time`.
     These methods were added to handle the limited range of Ruby's native Time
     implementation. Those limitations no longer apply so we are deprecating them in 4.0
