+Image.quantize
+^^^^^^^^^^^^^^
+
+The ``dither`` option is now a customisable parameter (was previously hardcoded to ``1``).
+This parameter takes the same values used in ``Image.convert``.
+
+New language parameter
+^^^^^^^^^^^^^^^^^^^^^^
+
+These text-rendering functions now accept a ``language`` parameter to request
