+udev 104
+========
+Bugfixes.
+
+udev 103
+========
+Add additional check to volume_id detection of via_raid, cause
+some company decided to put a matching pattern all over the empty
+storage area of their music players.
+
+udev 102
+========
+Fix path_id for SAS devices.
+
+udev 101
+========
+The udev daemon can be started with --debug-trace now, which will
+execute all events serialized to get a chance to catch a possible
+action that crashes the box.
+
+A warning is logged, if PHYSDEV* keys, the "device" link, or a parent
+device attribute like $attr{../file} is used, only WAIT_FOR_SYSFS rules
+are excluded from the warning. Referencing parent attributes directly
+may break when something in the kernel driver model changes. Udev will
+just find the attribute by walking up the parent chain.
+
+Udevtrigger now sorts the list of devices depending on the device
+dependency, so a "usb" device is triggered after the parent "pci"
+device.
+
+udev 100
+========
+Revert persistent-storage ata-serial '_' '-' replacement.
+
+udev 099
+========
+Bugfixes.
+
+Udevtrigger can now filter the list of devices to be triggered. Matches
+for subsystems or sysfs attributes can be specified.
+
+The entries in /dev/.udev/queue and /dev/.udev/failed have changed to
+zero-sized files to avoid pointing to /sys and confuse broken tools which
+scan the /dev directory. To retry failed events, udevtrigger --retry-failed
+should be used now.
+
+The rules and scripts to create udev rules for persistent network
+devices and optical drives are in the extras/rules_generator directory
+now. If you use something similar, please consider replacing your own
+version with this, to share the support effort. The rule_generator
+installs its own rules into /etc/udev/rules.d.
+
+The cdrom_id tool installs its own rule now in /etc/udev/rules.d, cause
+the rule_generator depends on cdrom_id to be called in an earlier rule.
+
+udev 098
+========
+Bugfixes.
+
+Renaming of some key names (the old names still work):
+BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
+(The behavior of the key DRIVER will change soon in one of the next
+releases, to match only the event device, please switch to DRIVERS
+instead. If DRIVER is used, it will behave like DRIVERS, but an error
+is logged.
+With the new key names, we have a more consistent and simpler scheme.
+We can match the properties of the event device only, with: KERNEL,
+SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
+with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
+longer mentioned in the man page and should be switched in the rule
+files.
+
+ATTR{file}="value" can be used now, to write to a sysfs file of the
+event device. Instead of:
+ ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
+we now can do:
+ ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
+
+All the PHYSDEV* keys are deprecated and will be removed from a
+future kernel:
+ PHYDEVPATH - is the path of a parent device and should not be
+ needed at all.
+ PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
+ matched with SUBSYSTEMS==
+ PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
+ Newer kernels will have DRIVER in the environment,
+ for older kernels udev puts in. Class device will
+ no longer carry this property of a parent and
+ DRIVERS== can be used to match such a parent value.
+Note that ENV{DRIVER} is only available for a few bus devices, where
+the driver is already bound at device event time. On coldplug, the
+events for a lot devices are already bound to a driver, and they will have
+that value set. But on hotplug, at the time the kernel creates the device,
+it can't know what driver may claim the device after that, therefore
+in most cases it will be empty.
+
+Failed events should now be re-triggered with:
+ udevtrigger --retry-failed.
+Please switch to this command, so we keep the details of the /dev/.udev/failed/
+files private to the udev tools. We may need to switch the current symlink
+target, cause some obviously broken tools try to scan all files in /dev
+including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
+million times. This takes ages on slow boxes.
+
+The udevinfo attribute walk (-a) now works with giving a device node
+name (-n) instead of a devpath (-p). The query now always works, also when
+no database file was created by udev.
+
+The built-in /etc/passwd /etc/group parser is removed, we always depend on
+getpwnam() and getgrnam() now. One of the next releases will depend on
+fnmatch() and may use getopt_long().

+========
+Fix path_id for recent kernels.
+
+udev 095
+========
+%e is finally gone.
+
+Added support for swapping network interface names, by temporarily
+renaming the device and wait for the target name to become free.
+
+udev 094
+========
+The built-in MODALIAS key and substitution is removed.
+
+udev 093
+========
+The binary firmware helper is replaced by the usual simple
+shell script. Udevsend is removed from the tree.
+
+udev 092
+========
+Bugfix release.
+
+udev 091
+========
+Some more keys require the correct use of '==' and '=' depending
+on the kind of operation beeing an assignment or a match. Rules
+with invalid operations are skipped and logged to syslog. Please
+test with udevtest if the parsing of your rules throws errors and
+fix possibly broken rules.
+
+udev 090
+========
+Provide "udevsettle" to wait for all current udev events to finish.
+It also watches the current kernel netlink queue by comparing the
+even sequence number to make sure that there are no current pending
+events that have not already arrived in the daemon.
+
+udev 089
+========
+Fix rule to skip persistent rules for removable IDE devices, which
+also skipped optical IDE drives.
+
+All *_id program are installed in /lib/udev/ by default now.
+
+No binary is stripped anymore as this should be done in the
+packaging process and not at build time.
+
+libvolume_id is provided as a shared library now and vol_id is
+linked against it. Also one of the next HAL versions will require
+this library, and the HAL build process will also require the
+header file to be installed. The copy of the same code in HAL will
+be removed to have only a single copy left on the system.
+
+udev 088
+========
+Add persistent links for SCSI tapes. The rules file is renamed
+to 60-persistent-storage.rules.
+
+Create persistent path for usb devices. Can be used for all sorts
+of devices that can't be distinguished by other properties like
+multiple identical keyboards and mice connected to the same box.
+
+Provide "udevtrigger" program to request events on coldplug. The
+shell script is much too slow with thousends of devices.
+
+udev 087
+========
+Fix persistent disk rules to exclude removable IDE drives.
+
+Warn if %e, $modalias or MODALIAS is used.
+
+udev 086
+========
+Fix queue export, which wasn't correct for subsequent add/remove
+events for the same device.
+
+udev 085
+========
+Fix cramfs detection on big endian.
+
+Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole
+device goes away.
+
+udev 084
+========
+If BUS== and SYSFS{}== have been used in the same rule, the sysfs
+attributes were only checked at the parent device that matched the
+by BUS requested subsystem. Fix it to also look at the device we
+received the event for.
+
+Build variable CROSS has changed to CROSS_COMPILE to match the kernel
+build name.
+
+udev 083
+========
+Fix a bug where NAME="" would prevent RUN from beeing executed.
+
+RUN="/bin/program" does not longer automatically add the subsystem
+as the first parameter. This is from the days of /sbin/hotplug
+which is dead now and it's just confusing to need to add a space at
+the end of the program name to prevent this.
+If you use rules that need the subsystem as the first parameter,
+like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem
+to the key like RUN+="/bin/program $env{SUBSYSTEM}".
+
+udev 082
+========
+The udev man page has moved to udev(7) as it does not describe a command
+anymore. The programs udev, udevstart and udevsend are no longer installed
+by default and must be copied manually, if they should be installed or
+included in a package.
+
+Fix a bug where "ignore_device" could run earlier collected RUN keys before
+the ignore rule was applied.
+
+More preparation for future sysfs changes. usb_id and scsi_id no longer
+depend on a magic order of devices in the /devices chain. Specific devices
+should be requested by their subsytem.
+
+This will always find the scsi parent device without depending on a specific
+path position:
+ dev = sysfs_device_get(devpath);
+ dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi");
+
+The "device" link in the current sysfs layout will be automatically
+_resolved_ as a parent and in the new sysfs layout it will just _be_ the
+parent in the devpath. If a device is requested by it's symlink, like all
+class devices in the new sysfs layout will look like, it gets automatically
+resolved and substituted with the real devpath and not the symlink path.
+
+Note:
+A similar logic must be applied to _all_ sysfs users, including
+scripts, that search along parent devices in sysfs. The explicit use of
+the "device" link must be avoided. With the future sysfs layout all
+DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting
+back to the "class" or the "bus". The layout of the parent devices in
+/devices is not necessarily expected to be stable across kernel releases and
+searching for parents by their subsystem should make sysfs users tolerant
+for changed parent chains.
