+========
+The default install location moved from /lib/udev to /usr/lib/udev,
+to support systems without the / vs. /usr split. --libexecdir=
+can still be configured to install things to /lib/udev.
+
+The default install location of the 'udevadm' tool moved from 'sbin'
+to /usr/bin. --bindir= can still be configured to install it in
+/sbin. Some tools expect udevadm in 'sbin'. A symlink to udevadm
+in /usr/bin needs to be manually created if needed.
+
+Kernel modules are now loaded directly by linking udev to 'libkmod'.
+The /sbin/modprobe tool is no longer executed by udev.
+
+The /sbin/blkid tool is no longer executed from udev rules. Udev links
+directly to libblkid now.
+
+Firmware is loaded natively by udev now, the external firmware loading
+binary is no longer used.
+
+All built-in tools can be listed and tested with 'udevadm test-builtin'.
+
+The 'udevadm control --reload-rules' option has been renamed to '--reload'.
+It reloads the kernel module configuration.
+
+The systemd socket files use PassCred=yes, which requires systemd
+version 38.
+
+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.
