 ==================
 
-- Setuptools 38.2.0 started supporting wheels. This interfered with buildout's

+- Setuptools 38.2.0 started supporting wheels. Through setuptools, buildout
+  now also supports wheels!
+
+  This setuptools change interfered with buildout's recent support for
+  `buildout.wheel <https://github.com/buildout/buildout.wheel>`_, resulting in
+  a sudden "Wheels are not supported" error message (see `issue 435
+  <https://github.com/buildout/buildout/issues/425>`_). Fixed by making
+  setuptools the default, though you can still use the buildout.wheel if you
+  want.
