+3.0.0
+=====
+
+Saving Multipage Images
+-----------------------
+
+There is now support for saving multipage images in the `GIF` and
+`PDF` formats. To enable this functionality, pass in `save_all=True`
+as a keyword argument to the save::
+
+    im.save('test.pdf', save_all=True)
+
+Tiff ImageFileDirectory Rewrite
+-------------------------------
+
+The Tiff ImageFileDirectory metadata code has been rewritten. Where
+previously it returned a somewhat arbitrary set of values and tuples,
+it now returns bare values where appropriate and tuples when the
+metadata item is a sequence or collection.
+
+The original metadata is still available in the TiffImage.tags, the
+new values are available in the TiffImage.tags_v2 member. The old
+structures will be deprecated at some point in the future.  When
+saving Tiff metadata, new code should use the
+TiffImagePlugin.ImageFileDirectory_v2 class.
+
+Deprecated Methods
+------------------
+
+Several methods that have been marked as deprecated for many releases
+have been removed in this release::
+
+    Image.tostring() 
+    Image.fromstring()
+    Image.offset()
+    ImageDraw.setink()
+    ImageDraw.setfill()
+    The ImageFileIO module
+    The ImageFont.FreeTypeFont and ImageFont.truetype `file` keyword arg
+    The ImagePalette private _make functions
+    ImageWin.fromstring()
+    ImageWin.tostring()
+
