+Updates
+=======
+
+Changes made since CMake 3.9.0 include the following.
+
+3.9.1
+-----
+
+* The ``find_`` command ``PACKAGE_ROOT`` search path group added by
+  CMake 3.9.0 has been removed for the 3.9 series due to regressions
+  caused by new use of ``<PackageName>_ROOT`` variables.  The behavior
+  may be re-introduced in the future in a more-compatible way.
