+Fix for a possible segfault while swapping network interface names in udev
+versions 131-134.
+
+udev 134
+========
+Bugfixes.
+
+The group "video" is part of the default rules now.
+
+udev 133
+========
+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, and the
+new rules parsing/matching code reduces the total in-memory size of
+a huge distro rule sets 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 prevent
+mis-detection with conflicting left-over signatures found from earlier
+file system formats. That way, we no longer depend on the probe-order
+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
+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.
+
+udev 131
+========
+Bugfixes. (And maybe new bugs. :))
+
+The rule matching engine got converted from a rule list to a token
+array which reduced the in-memory rules representation of a full
+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>".
+
+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.
+
+Many thanks to Alan Jenkins for his continuous help, and finding and
+optimizing some of the computing expensive parts.
+
+udev 130
+========
+Bugfixes.
+
+Kernel devices and device nodes are connected now by reverse indizes in
+/sys and /dev. A device number retrieved by a stat() or similar, the
+kernel device directory can be found by looking up:
+ /sys/dev/{block,char}/<maj>:<min>
+and the device node of the same device by looking up:
+ /dev/{block,char}/<maj>:<min>
+
+udev 129
+========
+Fix recently introduced bug, which caused a compilation without large
+file support, where vol_id does not recognize raid signatures at the end
+of a volume.
+
+Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links.
+Seems some kernel versions prevent the creation of the ieee-* links,
+so people used the scsi-* link which disappeared now.
+
+More libudev work. Almost all udevadm functionality comes from libudev
+now.
+
+udevadm trigger has a new option --type, which allows to trigger events
+for "devices", for "subsystems", or "failed" devices. The old option
+--retry-failed" still works, but is no longer mentioned in the man page.
+
+udev 128
+========
+Bugfixes.
+
+The udevadm info --device-id-of-file= output has changed to use
+the obvious format. Possible current users should use the --export
+option which is not affected.
+
+The old udev commands symlinks to udevadm are not installed, if
+these symlinks are used, a warning is printed.
+
+udev 127
+========
+Bugfixes.
+
+Optical drive's media is no longer probed for raid signatures,
+reading the end of the device causes some devices to malfunction.
+Also the offset of the last session found is used now to probe
+for the filesystem.
+
+The volume_id library got a major version number update to 1,
+some deprecated functions are removed.
+
+A shared library "libudev" gets installed now to provide access
+to udev device information. DeviceKit, the successor of HAL, will
+need this library to access the udev database and search sysfs for
+devices.
+The library is currently in an experimental state, also the API is
+expected to change, as long as the DeviceKit integration is not
+finished.

========
We use ./configure now. See INSTALL for details. Current
--disable-logging
disable all logging and compile-out all log strings
--with-selinux
- link against SELInux libraries to set the expected context
+ link against SELInux libraries, to set the expected context
for created files
-No symlinks to udevadm are installed anymore, if still neded, the
-package should create them.
+In the default rules, the group "disk" gets permissions 0660 instead
+of 0640. One small step closer to unify distro rules. Some day, all
+distros hopefully end up with the same set of rules.
+
+No symlinks to udevadm are installed anymore, if they are still needed,
+they should be provided by the package.
