 API Changes
 ===========
 
-TODO
-^^^^
+Image.alpha_composite: dest
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-TODO
+When calling :py:meth:`~PIL.Image.Image.alpha_composite`, the ``dest`` argument now
+accepts negative co-ordinates, like the upper left corner of the ``box`` argument of
+:py:meth:`~PIL.Image.Image.paste` can be negative. Naturally, this has effect of
+cropping the overlaid image.
+
+Image.getexif: EXIF and GPS IFD
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Previously, :py:meth:`~PIL.Image.Image.getexif` flattened the EXIF IFD into the rest of
+the data, losing information. This information is now kept separate, moved under
+``im.getexif().get_ifd(0x8769)``.
+
+Direct access to the GPS IFD dictionary was possible through ``im.getexif()[0x8825]``.
+This is now consistent with other IFDs, and must be accessed through
+``im.getexif().get_ifd(0x8825)``.
+
+These changes only affect :py:meth:`~PIL.Image.Image.getexif`, introduced in Pillow
+6.0. The older ``_getexif()`` methods are unaffected.
 
 API Additions
 =============
 
-TODO
-^^^^
+ImageDraw.rounded_rectangle
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-TODO
+Added :py:meth:`~PIL.ImageDraw.ImageDraw.rounded_rectangle`. It works the same as
+:py:meth:`~PIL.ImageDraw.ImageDraw.rectangle`, except with an additional ``radius``
+argument. ``radius`` is limited to half of the width or the height, so that users can
+create a circle, but not any other ellipse.
+
+.. code-block:: python
+
+    from PIL import Image, ImageDraw
+    im = Image.new("RGB", (200, 200))
+    draw = ImageDraw.Draw(im)
+    draw.rounded_rectangle(xy=(10, 20, 190, 180), radius=30, fill="red")
+
+ImageShow.IPythonViewer
+^^^^^^^^^^^^^^^^^^^^^^^
+
+If IPython is present, this new :py:class:`PIL.ImageShow.Viewer` subclass will be
+registered. It displays images on all IPython frontends. This will be helpful
+to users of Google Colab, allowing ``im.show()`` to display images.
+
+It is lower in priority than the other default :py:class:`PIL.ImageShow.Viewer`
+instances, so it will only be used by ``im.show()`` or :py:func:`.ImageShow.show()`
+if none of the other viewers are available. This means that the behaviour of
+:py:class:`PIL.ImageShow` will stay the same for most Pillow users.
+
+Saving TIFF with ICC profile
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+As is already possible for JPEG, PNG and WebP, the ICC profile for TIFF files can now
+be specified through a keyword argument::
+
+    im.save("out.tif", icc_profile=...)

+
+[![Linux & macOS build](https://travis-ci.org/HOST-Oman/libraqm.svg?branch=master)](https://travis-ci.org/HOST-Oman/libraqm)
+[![Windows build](https://img.shields.io/appveyor/ci/HOSTOman/libraqm/master.svg)](https://ci.appveyor.com/project/HOSTOman/libraqm)
+
+Raqm is a small library that encapsulates the logic for complex text layout and
+provides a convenient API.
+
+It currently provides bidirectional text support (using [FriBiDi][1]), shaping
+(using [HarfBuzz][2]), and proper script itemization. As a result,
+Raqm can support most writing systems covered by Unicode.
+
+The documentation can be accessed on the web at:
+> http://host-oman.github.io/libraqm/
+
+Raqm (Arabic: رَقْم) is writing, also number or digit and the Arabic word for
+digital (رَقَمِيّ) shares the same root, so it is a play on “digital writing”.
+
+Building
+--------
+
+Raqm depends on the following libraries:
+* [FreeType][3]
+* [HarfBuzz][2]
+* [FriBiDi][1]
+
+To build the documentation you will also need:
+* [GTK-Doc][4]
+
+To install dependencies on Fedora:
+
+    sudo dnf install freetype-devel harfbuzz-devel fribidi-devel gtk-doc
+
+To install dependencies on Ubuntu:
+
+    sudo apt-get install libfreetype6-dev libharfbuzz-dev libfribidi-dev \
+                         gtk-doc-tools
+
+On Mac OS X you can use Homebrew:
+
+    brew install freetype harfbuzz fribidi gtk-doc
+    export XML_CATALOG_FILES="/usr/local/etc/xml/catalog" # for the docs
+
+Once you have the source code and the dependencies, you can proceed to build.
+To do that, run the customary sequence of commands in the source code
+directory:
+
+    $ ./configure
+    $ make
+    $ make install
+
+To build the documentation, pass `--enable-gtk-doc` to the `configure` script.
+
+To run the tests:
+
+    $ make check
+
+Contributing
+------------
+
+Once you have made a change that you are happy with, contribute it back, we’ll
+be happy to integrate it! Just fork the repository and make a pull request.
