   . pcntl_exec() now throws ValueErrors when entries or keys of the
     $env_vars parameter contain null bytes.
 
+- PDO:
+  . The constructor arguments set in conjunction with PDO::FETCH_CLASS now
+    follow the usual CUFA semantics.
+    This means string keys will act like a named argument.
+    Moreover, automatic wrapping for by-value arguments passed to a by-ref
+    parameter has been removed, and the usual E_WARNING about this is now
+    emitted.
+    To pass a variable by-ref to a constructor argument use the general
+    array value reference assignment: $ctor_args = [&$valByRef]
+  . Attempting to modify a PDOStatement during a call to PDO::fetch(),
+    PDO::fetchObject(), PDO::fetchAll() will now throw an Error.

 - PDO_FIREBIRD:
   . A ValueError is now thrown when trying to set a cursor name that is too
     long on a PDOStatement resulting from the Firebird driver.
