+Step 2: Remove usage of the APC Cache driver (deprecation)
+==========================================================
+
+The :doc:`Cache Library <../libraries/caching>` APC driver is now
+deprecated, as the APC extension is effectively dead, as explained in its
+`PHP Manual page <https://secure.php.net/manual/en/intro.apc.php>`_.
+
+If your application happens to be using it, you can switch to another
+cache driver, as APC support will be removed in a future CodeIgniter
+version.
+
+.. note:: The driver is still available, but you're strongly encouraged
+	to remove its usage sooner rather than later.
