 ^^^^^^^^^^^^^^^^^^

-``im.mode = "RGBA"``, you will now receive an ``AttributeError``. This is
+``im.mode = "RGBA"``, you will now receive an :py:exc:`AttributeError`. This is

+has_transparency_data
+^^^^^^^^^^^^^^^^^^^^^
 
-TODO
-^^^^
+Images now have :py:attr:`~PIL.Image.Image.has_transparency_data` to indicate
+whether the image has transparency data, whether in the form of an alpha
+channel, a palette with an alpha channel, or a "transparency" key in the
+:py:attr:`~PIL.Image.Image.info` dictionary.

+
+ImageOps.cover
+^^^^^^^^^^^^^^
+
+Returns a resized version of the image, so that the requested size is covered,
+while maintaining the original aspect ratio.
+

+methods.
+
+size and font_size arguments when using default font
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Pillow has had a "better than nothing" default font, which can only be drawn at
+one font size. Now, if FreeType support is available, a version of
+`Aileron Regular <https://dotcolon.net/font/aileron>`_ is loaded, which can be
+drawn at chosen font sizes.
+
+The following ``size`` and ``font_size`` arguments can now be used to specify a
+font size for this new builtin font::
+
+    ImageFont.load_default(size=24)
+    draw.text((0, 0), "test", font_size=24)
+    draw.textlength((0, 0), "test", font_size=24)
