+Image.open: add formats parameter
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Added a new ``formats`` parameter to :py:func:`.Image.open`:
+
+* A list or tuple of formats to attempt to load the file in.
+  This can be used to restrict the set of formats checked.
+  Pass ``None`` to try all supported formats. You can print the set of
+  available formats by running ``python -m PIL`` or using
+  the :py:func:`PIL.features.pilinfo` function.

 ImageOps.autocontrast: add mask parameter
