+udev 137
+========
+Bugfixes.
+
+The udevadm test command has no longer a --force option, nodes and symlinks
+are always updated with a test run now.
+
+The udevd daemon can be started with --resolve-names=never to avoid all user
+and group lookups (e.g. in cut-down systems) or --resolve-names=late to
+lookup user and groups every time events are handled.
