systemd System and Service Manager
+CHANGES WITH 218:
+
+ * If compiled with --enable-xkbcommon, systemd-localed will
+ verify x11 keymap settings by compiling the given keymap. It
+ will spew out warnings if the compilation fails. This
+ requires libxkbcommon to be installed.
+
+ * All systemd programs that read standalone configuration files
+ in /etc now also support a corresponding series of
+ .conf.d configuration directories in /etc/, /run/,
+ /usr/local/lib/, /usr/lib/, and (if configured with
+ --enable-split-usr) /lib/. In particular, the following
+ configuration files now have corresponding configuration
+ directories: system.conf user.conf, logind.conf,
+ journald.conf, sleep.conf, bootchart.conf, coredump.conf,
+ resolved.conf, timesyncd.conf, journal-remote.conf, and
+ journal-upload.conf. Note that distributions should use the
+ configuration directories in /usr/lib/; the directories in
+ /etc/ are reserved for the system administrator.
+
CHANGES WITH 217:
* journalctl gained the new options -t/--identifier= to match
show log timestamps in the UTC timezone. journalctl now also
accepts -n/--lines=all to disable line capping in a pager.
+ * journalctl gained a new switch, --flush, that synchronously
+ flushes logs from /run/log/journal to /var/log/journal if
+ persistent storage is enabled. systemd-journal-flush.service
+ now waits until the operation is complete.
+
* Services can notify the manager before they start a reload
(by sending RELOADING=1) or shutdown (by sending
STOPPING=1). This allows the manager to track and show the

+ * "udevadm hwdb --update" learnt a new switch "--usr" for
+ placing the rebuilt hardware database in /usr instead of
+ /etc. When used only hardware database entries stored in
+ /usr will be used, and any user database entries in /etc are
+ ignored. This functionality is useful for vendors to ship a
+ pre-built database on systems where local configuration is
+ unnecessary or unlikely.
+
+ * Calendar time specifications in .timer units now also
+ understand the strings "semi-annually", "quarterly" and
+ "minutely" as shortcuts (in addition to the preexisting
+ "anually", "hourly", ...).
+
+ * systemd-tmpfiles will now correctly create files in /dev
+ at boot which are marked for creation only at boot. It is
+ recommended to always create static device nodes with 'c!'
+ and 'b!', so that they are created only at boot and not
+ overwritten at runtime.
+
+ * When the watchdog logic is used for a service (WatchdogSec=)
+ and the watchdog timeout is hit the service will now be
+ terminated with SIGABRT (instead of just SIGTERM), in order
+ to make sure a proper coredump and backtrace is
+ generated. This ensures that hanging services will result in
+ similar coredump/backtrace behaviour as services that hit a
+ segmentation fault.
