+==================
+
+The :ref:`Required Filters <filters-required>` has been introduced. They are new
+special filters that are applied before and after other kinds of filters, and
+always applied even if a route does not exist.
+
+The following existing functionalities have been reimplemented as Required Filters.
+
+- :ref:`Force Global Secure Requests <forcehttps>`
+- :doc:`../general/caching`
+- :ref:`performancemetrics`
+- :ref:`the-debug-toolbar`
+
+The Benchmark **Timers** used by Debug Toolbar now collect *Required Before Filters*
+and *Required After Filters* data.
+
+The benchmark points have been changed:
+
