+udev 133
+========
+
+The strings of the parsed rules, which are kept in memory, no longer
+contain duplicate entries, or duplicate tails of strings. This reduces
+the total in-memory size of a huge distro rule set to 0.08 MB, compared
+to the 1.2MB of udev version 130.
+
+The export of DEVTYPE=disk/partition got removed from the default
+rules. This value is available from the kernel.
+The pnp shell script modprobe hack is removed from the default rules.
+ACPI devices have proper modalias support and take care of the same
+functionality.
+Installations which support old kernels, but install current default
+udev rules may want to add that to the compat rules file.
+
+Libvolume_id now always probes for all known filesystems, and does not
+stop at the first match. Some filesystems are marked as "exclusive probe",
+and if any other filesytem type matches at the same time, libvolume_id
+will by default not return any probing result. This is intended to help
+with conflicting left-over signatures from earlier file system formats.
+That way, we no longer depend on the probe-order in case of competing
+signatures. In some setups the kernel allows to mount a volume with just
+the old filesystem signature still in place. This may damage the new
+filesystem and cause data-loss, just by mounting it. Because volume_id
+can not decide which one the correct signature is, the wrong signatures
+need to be removed manually from the volume, or the volume needs to be
+reformatted, to enable filesystem detection and possible auto-mounting.
