+* Mon Aug  8 2011 Richard W.M. Jones <rjones@redhat.com> - 1:1.13.3-4
 - New upstream version 1.13.3.
-- Remove hack for daemon/tests.  Directory no longer exists.
+- 'test-getlogin_r.c:55: assertion failed' test must now be fixed in
+  gnulib/tests directory instead of daemon/tests (the latter directory
+  no longer exists).
 - Only run testsuite on x86_64 because of qemu bug.
