+Bugs reported after the release of 3.7.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This file lists bugs that were reported after 3.7.0 was released, both
+in 3.7.0 and trunk, and that have not been closed. Bugs that have
+been closed as "fixed" are listed in the top level NEWS file instead.
+In other words they get listed here first and moved to NEWS if they
+get fixed.
