+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().
+
+udev 097
+========
+Bugfixes and small improvements.
+
+udev 096
+========
+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.
+
+udev 081
+========
+Prepare udev to work with the experimental kernel patch, that moves
+/sys/class devices to /sys/devices and /sys/block to /sys/class/block.
+
+Clarify BUS, ID, $id usage and fix $id behavior. This prepares for
+moving the class devices to /sys/devices.
+
+Thanks again to Marco for help finding a hopefully nice compromise
+to make %b simpler and working again.
+
+udev 080
+========
+Complete removal of libsysfs, replaced by simple helper functions
+which are much simpler and a bit faster. The udev daemon operatesentirely
+on event parameters and does not use sysfs for simple rules anymore.
+Please report any new bugs/problems, that may be caused by this big
+change. They will be fixed immediately.
+
+The enumeration format character '%e' is deprecated and will be
+removed sometimes from a future udev version. It never worked correctly
+outside of udevstart, so we can't use it with the new parallel
+coldplug. A simple enumeration is as useless as the devfs naming
+scheme, just get rid of both if you still use it.
+
+MODALIAS and $modalias is not needed and will be removed from one of
+the next udev versions, replace it in all rules with ENV{MODALIAS} or
+the sysfs "modalias" value.
+
+Thanks a lot to Marco for all his help on finding and fixing bugs.
+
+udev 079
+========
+Let scsi_id request libata drive serial numbers from page 0x80.
+
+Renamed etc/udev/persistent.rules to persistent-disk.rules and
+added /dev/disk/by-name/* for device mapper device names.
+
+Removed %e from the man page. It never worked reliably outside
+of udevstart and udevstart is no longer recommended to use.
+
+udev 078
+========
+Symlinks are now exported to the event environment. Hopefully it's no
+longer needed to run udevinfo from an event process, like it was
+mentioned on the hotplug list:
+ UDEV [1134776873.702967] add@/block/sdb
+ ...
+ DEVNAME=/dev/sdb
+ DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0
+
+udev 077
+========
+Fix a problem if udevsend is used as the hotplug handler and tries to use
+syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete
+and this kind of problems will hopefully go away soon.
+
+udev 076
+========
+All built-in logic to work around bad sysfs timing is removed with this
+version. The need to wait for sysfs files is almost fixed with a kernel
+version that doesn't work with this udev version anyway. Until we fix
+the timing of the "bus" link creation, the former integrated logic should
+be emulated by a rule placed before all other rules:
+ ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus"
+
+The option "udev_db" does no longer exist. All udev state will be in
+/$udev_root/.udev/ now, there is no longer an option to set this
+to anything else.
+If the init script or something else used this value, just depend on
+this hardcoded path. But remember _all_content_ of this directory is
+still private to udev and can change at any time.
+
+Default location for rule sripts and helper programs is now: /lib/udev/.
+Everything that is not useful on the commandline should go into this
+directory. Some of the helpers in the extras folder are installed there
+now. The rules need to be changed, to find the helpers there.
+
+Also /lib/udev/devices is recommended as a directory where packages or
+the user can place real device nodes, which get copied over to /dev at
+every boot. This should replace the various solutions with custom config
+files.
+
+Udevsend does no longer start the udev daemon. This must be done with
+the init script that prepares /dev on tmpfs and creates the initial nodes,
+before starting the daemon.
+
+udev 075
+========
+Silent a too verbose error logging for the old hotplug.d/ dev.d/
+emulation.
+
+The copy of klibc is removed. A systemwide installed version of klibc
+should be used to build a klibc udev now.
+
+udev 074
+========
+NAME="" will not create any nodes, but execute RUN keys. To completely
+ignore an event the OPTION "ignore_device" should be used.
+
+After removal of the reorder queue, events with a TIMEOUT can be executed
+without any queuing now.
+
+udev 073
+========
+Fixed bug in udevd, if inotify is not available. We depend on netlink
+uevents now, kernels without that event source will not work with that
+version of udev anymore.
+
+udev 072
+========
+The rule parsing happens now in the daemon once at startup, all udev
+event processes inherit the already parsed rules from the daemon.
+It is shipped with SUSE10.0 and reduces heavily the system load at
+startup. The option to save precompiled rules and let the udev process
+pick the them up is removed, as it's no longer needed.
+
+Kernel 2.6.15 will have symlinks at /class/input pointing to the real
+device. Libsysfs is changed to "translate" the requested link into the
+real device path, as it would happen with the hotplug event. Otherwise
+device removal and the udev database will not work.
+
+Using 'make STRIPCMD=' will leave the binaries unstripped for debugging
+and packaging.
+
+A few improvements for vol_id, the filesytem probing code.
+
+udev 071
+========
+Fix a stupid typo in extras/run_directory for "make install".
+
+scsi_id creates the temporary devnode now in /dev for usage with a
+non-writable /tmp directory.
+
+The uevent kernel socket buffer can carry app. 50.000 events now,
+let's see who can break this again. :)
+
+The upcoming kernel will have a new input driver core integration.
+Some class devices are now symlinks to the real device. libsysfs
+needs a fix for this to work correctly. Udevstart of older udev
+versions will _not_ create these devices!
+
+udev 070
+========
+Fix a 'install' target in the Makefile, that prevents EXTRAS from
+beeing installed.
+
+udev 069
+========
+A bunch of mostly trivial bugfixes. From now on no node name or
+symlink name can contain any character than plain whitelisted ascii
+characters or validated utf8 byte-streams. This is needed for the
+/dev/disk/by-label/* links, because we import untrusted data and
+export it to the filesystem.
+
