+==============================
+
+PILLOW_VERSION constant
+^^^^^^^^^^^^^^^^^^^^^^^
+
+``PILLOW_VERSION`` has been removed. Use ``__version__`` instead.
+
+PyQt4 and PySide
+^^^^^^^^^^^^^^^^
+
+Qt 4 reached end-of-life on 2015-12-19. Its Python bindings are also EOL: PyQt4 since
+2018-08-31 and PySide since 2015-10-14.
+
+Support for PyQt4 and PySide has been removed from ``ImageQt``. Please upgrade to PyQt5
+or PySide2.
+
+Setting the size of TIFF images
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Setting the size of a TIFF image directly (eg. ``im.size = (256, 256)``) throws
+an error. Use ``Image.resize`` instead.
