-        * Enable unprivileged programs, neither setuid nor having file
-          capabilities, to send ICMP Echo requests by turning on the
-          net.ipv4.ping_group_range parameter of the Linux kernel for all
-          groups. If this is not desirable, then it can be disabled by setting
-          the parameter to "1 0".
+        * This release enables unprivileged programs (i.e. requiring neither
+          setuid nor file capabilities) to send ICMP Echo (i.e. ping) requests
+          by turning on the net.ipv4.ping_group_range sysctl of the Linux
+          kernel for the whole UNIX group range, i.e. all processes. This
+          change should be reasonably safe, as the kernel support for it was
+          specifically implemented to allow safe access to ICMP Echo for
+          processes lacking any privileges. If this is not desirable, it can be
+          disabled again by setting the parameter to "1 0".

+        * PID 1 now understands a new option KExecWatchdogSec= in
+          /etc/systemd/system.conf. It allows configuration of a watchdog
+          timeout to write to a hardware watchdog device on kexec-based
+          reboots. Previously this functionality was only available for regular
+          reboots. This option defaults to off, since it depends on drivers and
+          software setup whether the watchdog is correctly reset again after
+          the kexec completed, and thus for the general case not clear if safe
+          (since it might cause unwanted watchdog reboots after the kexec

+          has been renamed to RebootWatchdogSec= to more clearly communicate

+          compatibility.

         * The systemd.debug_shell kernel command line option now optionally
           takes a tty name to spawn the debug shell on, which allows selecting
