+Mayavi 4.7.2
+============
+
+The significant update for this release is that it is compatible with the
+latest VTK-9.x series and is known to work with VTK 9.0.1 from PyPI. The
+picker UI has changed to no longer pop up a UI window but instead show the
+picked attributes on the render window directly. The original picker UI is now
+available on the scene's UI in a separate "Picker" tab. This is accessible
+from either the pipeline view when one edits the properties of a scene or
+through the "configure scene" gear icon on the scene window toolbar.
+
+Many thanks to the following who contributed to this release (in alphabetical
+order):
+
+Amal S Sebastian, Eric Larson, Guillaume Favelier, Hans Moritz Günther, Magnus
+Nord, Mark Dickinson, Poruri Sai Rahul, Prabhu Ramachandran, Scott Talbert,
+Tetsuo Koyama.
+
+This is largely a bug-fix release with one enhancement/change.
