+========
+The udevadm tool moved from 'sbin' to 'bin'. Some tools expect
+udevadm in 'sbin'. A symlink to udevadm in 'bin' needs to be
+manually created if needed.
+
+The systemd socket files use PassCred=yes, which requires systemd
+version 38.

Bugfixes.
-The path_id, usb_id, input_id tools are built-in commands now
-and the stand-alone tools do not exist anymore. For testing,
-the commands can be run with 'udevadm test-builtin <cmd>'.
+The udev daemon moved to /lib/udev/udevd. Non-systemd init systems
+and non-dracut initramfs image generators need to change the init
+scripts. Alternatively the udev build needs to move udevd back to
+/sbin or create a symlink in /sbin, which is not done by default.
+
+The path_id, usb_id, input_id tools are built-in commands now and
+the stand-alone tools do not exist anymore. Static lists of file in
+initramfs generators need to be updated. For testing, the commands
+can still be executed standalone with 'udevadm test-builtin <cmd>'.
The fusectl filesystem is no longer mounted directly from udev.
Systemd systems will take care of mounting fusectl and configfs
now. Non-systemd systems need to ship their own rule if they
need these filesystems auto-mounted.
+The long deprecated keys: SYSFS=, ID=, BUS= have been removed.
+
+The support for 'udevadm trigger --type=failed, and the
+RUN{fail_event_on_error} attribute was removed.
+
+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.
