+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.

+Fix segfault if compiled without optimization and dbg() does not get
+compiled out and uses variables which are not available.

 The rule matching engine got converted from a rule list to a token
 array which reduced the in-memory rules representation of a full

-The limit of 5 ENV and ATTR matches, and a single instance for most
-other keys per rule is gone with the new parser.
+featured distros with thousends of udev rules from 1.2MB to 0.12 MB.
+Limits like 5 ENV and ATTR matches, and one single instance for most
+other keys per rule are gone.
 
 The NAME assignment is no longer special cased. If later rules assign
 a NAME value again, the former value will be overwritten. As usual
 for most other keys, the NAME value can be protected by doing a final
 assignment with NAME:="<value>".
 
-Many thanks to Alan Jenkins for finding and optimizing some of the

+All udev code now uses libudev, which is also exported. The library
+is still under development, marked as experimental, and its interface
+may change as long as the DeviceKit integration is not finished.
