+udev 171
+========
+!!! revert: "systemd: trigger - run after udev.service (for now)"
+
+The systemd service files require systemd version 28. The systemd
+socket activation make it possible now to start 'udevd' and 'udevadm
+trigger' in parallel.
+
+udev 170
+========
+Fix bug in control message handling, which can lead to a failing
+udevadm control --exit. Thanks to Jürg Billeter for help tracking
+it down.
+
+udev 169
+========
+Bugfixes.
+
+We require at least Linux kernel 2.6.32 now. Some platforms might
+require a later kernel that supports accept4() and similar, or
+need to backport the trivial syscall wiring to the older kernels.
+
+The hid2hci tool moved to the bluez package and was removed.
+
+Many of the extras can be --enable/--disabled at ./configure
+time. The --disable-extras option was removed. Some extras have
+been disabled by default. The current options and their defaults
+can be checked with './configure --help'.
+
+udev 168
+========
+Bugfixes.
+
+Udev logs a warning now if /run is not writable at udevd
+startup. It will still fall back to /dev/.udev, but this is
+now considered a bug.
+
+The running udev daemon can now cleanly shut down with:
+  udevadm control --exit
+
+Udev in initramfs should clean the state of the udev database
+with: udevadm info --cleanup-db which will remove all state left
+behind from events/rules in initramfs. If initramfs uses
+--cleanup-db and device-mapper/LVM, the rules in initramfs need
+to add OPTIONS+="db_persist" for all dm devices. This will
+prevent removal of the udev database for these devices.
+
+Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of
+120 seconds per process. If that timeout is reached the spawned
+process will be killed. The event timeout can be overwritten with
+udev rules.
+
+If systemd is used, udev gets now activated by netlink data.
+Systemd will bind the netlink socket which will buffer all data.
+If needed, such setup allows a seemless update of the udev daemon,
+where no event can be lost during a udevd update/restart.
+Packages need to make sure to: systemctl stop udev.socket udev.service
+or 'mask' udev.service during the upgrade to prevent any unwanted
+auto-spawning of udevd.
+This version of udev conflicts with systemd version below 25. The
+unchanged service files will not wirk correctly.
+
+udev 167
+========
+Bugfixes.
+
+The udev runtime data moved from /dev/.udev/ to /run/udev/. The
+/run mountpoint is supposed to be a tmpfs mounted during early boot,
+available and writable to for all tools at any time during bootup,
+it replaces /var/run/, which should become a symlink some day.
+
+If /run does not exist, or is not writable, udev will fall back using
+/dev/.udev/.
+
+On systemd systems with initramfs and LVM used, packagers must
+make sure, that the systemd and initramfs versions match. The initramfs
+needs to create the /run mountpoint for udev to store the data, and
+mount this tmpfs to /run in the rootfs, so the that the udev database
+is preserved for the udev version started in the rootfs.
+
+The command 'udevadm info --convert-db' is gone. The udev daemon
+itself, at startup, converts any old database version if necessary.
+
+The systemd services files have been reorganized. The udev control
+socket is bound by systemd and passed to the started udev daemon.
+The udev-settle.service is no longer active by default. Services which
+can not handle hotplug setups properly need to actively pull it in, to
+act like a barrier. Alternatively the settle service can be unconditionally
+'systemctl'enabled, and act like a barrier for basic.target.
+
+The fstab_import callout is no longer built or installed. Udev
+should not be used to mount, does not watch changes to fstab, and
+should not mirror fstab values in the udev database.
+
+udev 166
+========
+Bugfixes.
+
+New and updated keymaps.
+
 udev 165
 ========
 Bugfixes.
 
+The udev database has changed, After installation of a new udev
+version, 'udevadm info --convert-db' should be called, to let the new
+udev/libudev version read the already stored data.
+
+udevadm now supports quoting of property values, and prefixing of
+key names:
+  $ udevadm info --export --export-prefix=MY_ --query=property -n sda
+  MY_MAJOR='259'
+  MY_MINOR='0'
+  MY_DEVNAME='/dev/sda'
+  MY_DEVTYPE='disk'
+  ...
+
+libudev now supports:
+  udev_device_get_is_initialized()
+  udev_enumerate_add_match_is_initialized()
+to be able to skip devices the kernel has created , but udev has
+not already handled.
+
+libudev now supports:
+  udev_device_get_usec_since_initialized()
+to retrieve the "age" of a udev device record.
+
+GUdev supports a more generic GUdevEnumerator class, udev TAG
+handling, device initialization and timestamp now.
+
+The counterpart of /sys/dev/{char,block}/$major:$minor,
+/dev/{char,block}/$major:$minor symlinks are now unconditionally
+created, even when no rule files exist.
+
+New and updated keymaps.
