mdadm (3.3.2-5) unstable; urgency=medium
* use-tempnode-not-devnode.patch: change udev rules file to use
$tempnode which works both on wheezy and jessie udev, instead
of $devnode which only works in jessie. At this stage it is
better to make rules file compatible with old version instead
of adding versioned dependency. Should be removed for jessie+1.
(Closes: #770883)
* fix Closes: list in previous entry (Closes: #771852)
