+udev 175
+========
+The default install location moved from /lib/udev to /usr/lib/udev
+to support systems without the / vs. /usr split. --libbexecdir=
+can still be configured to install things to the rootfs.
+
+The udevadm tool moved from /sbin to /usr/bin. Some tools expect
+udevadm in 'sbin'. A symlink to udevadm in 'bin' needs to be
+manually created if needed. Alternatively --bindir=/sbin installs
+udevadm in /sbin.
+
+The systemd socket files use PassCred=yes, which requires systemd
+version 38.
+
+The blkid tool is no longer called from udev rules. Udev links directly
+to libblkid now.
+
+The udev build system only creates a .xz tarball now.

========
Bugfixes.
The udev control socket is now created in /run/udev/control
and no longer as an abstract namespace one.
+The rules to create persistent network interface and cdrom link
+rules automatically in /etc/udev/rules.d/ have been disabled by
+default. Explicit configuration will be required for these use
+cases, udev will no longer try to write any persistent system
+configuration from a device hotplug path.
