+* #38: Fixed AttributeError when running with ``--dry-run``.
+  ``PyTest.run()`` no longer returns the result code. Based on
+  the commit message for `840ff4c <
+  https://github.com/pytest-dev/pytest-runner/commit/840ff4c2bf6c752d9770f0dd8d64a841060cf9bc>`_,
+  nothing has ever relied on that value.
