         * User units are now loaded also from
           $XDG_RUNTIME_DIR/systemd/user/. This is similar to the
           /run/systemd/user directory that was already previously

-        * A timeout for the start of the system can be configured. The
-          system can be configured to reboot or poweroff if the basic
-          system default target is not reached before the timeout (new
-          StartTimeoutSec=, StartTimeoutAction=,
-          StartTimeoutRebootArgument= options).
+        * Job timeouts (i.e. time-outs on the time a job that is
+          queued stays in the run queue) can now optionally result in
+          immediate reboot or power-off actions (JobTimeoutAction= and
+          JobTimeoutRebootArgument=). This is useful on ".target"
+          units, to limit the maximum time a target remains
+          undispatched in the run queue, and to trigger an emergency
+          operation in such a case. This is now used by default to
+          turn off the system if boot-up (as defined by everything in
+          basic.target) hangs and does not complete for at least
+          15min. Also, if power-off or reboot hang for at least 30min
+          an immediate power-off/reboot operation is triggered. This
+          functionality is particularly useful to increase reliability
+          on embedded devices, but also on laptops which might
+          accidentally get powered on when carried in a backpack and
+          whose boot stays stuck in a hard disk encryption passphrase
+          question.

+
+        * The default sysctl.d/ snippets will now set:
+
+                net.core.default_qdisc = fq_codel
+
+          This selects Fair Queueing Controlled Delay as the default
+          queueing discipline for network interfaces. fq_codel helps
+          fight the network bufferbloat problem. It is believed to be
+          a good default with no tuning required for most workloads.
+          Downstream distributions may override this choice. On 10Gbit
+          servers that do not do forwarding, "fq" may perform better.
+          Systems without a good clocksource should use "pfifo_fast".
+
+        * If kdbus is enabled during build a new option BusPolicy= is
+          available for service units, that allows locking all service
+          processes into a stricter bus policy, in order to limit
+          access to various bus services, or even hide most of them
+          from the service's view entirely.
+
+        * networkctl will now show the .network and .link file
+          networkd has applied to a specific interface.
+
+        * sd-login gained a new API call sd_session_get_desktop() to
+          query which desktop environment has been selected for a
+          session.
+
+        * UNIX utmp support is now compile-time optional to support
+          legacy-free systems.
+
+        * systemctl gained two new commands "add-wants" and
+          "add-requires" for pulling in units from specific targets
+          easily.
+
+        * If the word "rescue" is specified on the kernel command line
+          the system will now boot into rescue mode (aka
+          rescue.target), which was previously available only by
+          specifying "1" or "systemd.unit=rescue.target" on the kernel
+          command line. This new kernel command line option nicely
+          mirrors the already existing "emergency" kernel command line
+          option.
+
+        * New kernel command line options mount.usr=, mount.usrflags=,
+          usrfstype= have been added that match root=, rootflags=,
+          rootfstype= but allow mounting a specific file system to
+          /usr.
+
+        * The $NOTIFY_SOCKET is now also passed to control processesof
+          services, not only the main process.
+
+        * This version reenables support for fsck's -l switch. This
+          means at least version v2.25 of util-linux is required for
+          operation, otherwise dead-locks on device nodes may
+          occur. Again: you need to update util-linux to at least
+          v2.25 when updating systemd to v217.
+
+        * The "multi-seat-x" tool has been removed from systemd, as
+          its functionality has been integrated into X servers 1.16,
+          and the tool is hence redundant. It is recommended to update
+          display managers invoking this tool to simply invoke X
+          directly from now on, again.
