========
+Bugfix for kernels using SYSFS_DEPRECATED* option and finding parent
+block devices in some cases. No common distro uses this option anymore,
+and we do not get enough testing for this and recent udev versions. If
+this option is not needed to run some old distro with a new kernel,
+it should be disabled in the kernel config.
+
+Bugfix for the $links substitution variable, which may crash if no links
+are created. This should not happen in usual setups because we always
+create /dev/{block,char}/ links.
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 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

Installations which support old kernels, but install current default

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 one of these filesytem types match, libvolume_id will not return
-a probing result if any other filesystem type matches. This is intended
-to help with conflicting left-over signatures from earlier file system
-formats. That way, we no longer depend on the probing order for competing
-signatures.
-In some cases the kernel allows to mount a volume with the old filesystem
-type, before it has been re-formatted with a different type. This can
-damage the new filesystem and lead to data loss. Because volume_id can
-not decide which is the correct signature, the wrong signatures need to
-be removed manually from the volume, or the volume needs to be reformatted
-to make filesystem auto-detection and possible auto-mounting working.

+will, by default, not return any probing result. This is intended to prevent

+in case of multiple 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

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