+* Mon Jun 23 2014 Kyle McMartin <kyle@redhat.com>
+- Clamp CAP_LAST_CAP at /proc/sys/kernel/cap_last_cap's value in the
+  Python bindings test if possible, otherwise use the value from
+  <linux/capability.h> since the kernel now has 37 capabilities upstream,
+  but our builders are not that up to date.
