systemd System and Service Manager
+CHANGES WITH 218:
+
+ * When querying unit file enablement status (for example via
+ "systemctl is-enabled"), a new state "indirect" is now known
+ which indicates that a unit might not be enabled itself, but
+ another unit listed in its Alias= setting might be.
+
+ * Similar to the various existing ConditionXYZ= settings for
+ units there are now matching AssertXYZ= settings. While
+ failing conditions cause a unit to be skipped, but its job
+ to succeed, failing assertions declared like this will cause
+ a unit start operation and its job to fail.
+
+ * hostnamed now knows a new chassis type "embedded".
+
+ * systemctl gained a new "edit" command. When used on a unit
+ file this allows extending unit files with .d/ drop-in
+ configuration snippets or editing the full file (after
+ copying it from /usr/lib to /etc). This will invoke the
+ user's editor (as configured with $EDITOR), and reload the
+ modified configuration after editing.
+
+ * "systemctl status" now shows the suggested enablement state
+ for a unit, as declared in the (usually vendor-supplied)
+ system preset files.
+
+ * nss-myhostname will now resolve the single-label host name
+ "gateway" to the locally configured default IP routing
+ gateways, ordered by their metrics. This assigns a stable
+ name to the used gateways, regardless which ones are
+ currently configured. Note that the name will only be
+ resolved after all other name sources (if nss-myhostname is
+ configured properly) and should hence not negatively impact
+ systems that use the single-label host name "gateway" in
+ other contexts.
+
+ * systemd-inhibit now allows filtering by mode when listing
+ inhibitors.
+
+ * Scope and service units gained a new "Delegate" boolean
+ property, which when set allows processes running inside the
+ unit to further partition resources. This is primarily
+ useful for systemd user instances as well as container
+ managers.
+
+ * journald will now pick up audit messages directly from
+ the kernel, and log them like any other log message. The
+ audit fields are split up and fully indexed. This means that
+ journalctl in many ways is now a (nicer!) alternative to
+ ausearch, the traditional audit client. Note that this
+ implements only a minimal audit client, if you want the
+ special audit modes like reboot-on-log-overflow, please use
+ the traditional auditd instead, which can be used in
+ parallel to journald.
+
+ * The ConditionSecurity= unit file option now understands the
+ special string "audit" to check whether auditing is
+ available.
+
+ * journalctl gained two new commands --vacuum-size= and
+ --vacuum-time= to delete old journal files until the
+ remaining ones take up no more the specified size on disk,
+ or are not older than the specified time.
+
+ * A new, native PPPoE library has been added to sd-network,
+ systemd's library of light-weight networking protocols. This
+ library will be used in a future version of networkd to
+ enable PPPoE communication without an external pppd daemon.
+
+ * The busctl tool now understands a new "capture" verb that
+ works similar to "monitor", but writes a packet capture
+ trace to STDOUT that can be redirected to a file which is
+ compatible with libcap's capture file format. This can then
+ be loaded in Wireshark and similar tools to inspect bus
+ communication.
+
+ * The busctl tool now understands a new "tree" verb that shows
+ the object trees of a specific service on the bus, or of all
+ services.
+
+ * The busctl tool now understands a new "introspect" verb that
+ shows all interfaces and members of objects on the bus,
+ including their signature and values. This is particularly
+ useful to get more information about bus objects shown by
+ the new "busctl tree" command.
+
+ * The busctl tool now understands new verbs "call",
+ "set-property" and "get-property" for invoking bus method
+ calls, setting and getting bus object properties in a
+ friendly way.
+
+ * busctl gained a new --augment-creds= argument that controls
+ whether the tool shall augment credential information it
+ gets from the bus with data from /proc, in a possibly
+ race-ful way.
+
+ * nspawn's --link-journal= switch gained two new values
+ "try-guest" and "try-host" that work like "guest" and
+ "host", but do not fail if the host has no persistent
+ journalling enabled. -j is now equivalent to
+ --link-journal=try-guest.
+
+ * macvlan network devices created by nspawn will now have
+ stable MAC addresses.
+
+ * A new SmackProcessLabel= unit setting has been added, which
+ controls the SMACK security label processes forked off by
+ the respective unit shall use.
+
+ * 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.
+
+ * When a coredump is collected a larger number of metadata
+ fields is now collected and included in the journal records
+ created for it. More specifically control group membership,
+ environment variables, memory maps, working directory,
+ chroot directory, /proc/$PID/status, and a list of open file
+ descriptors is now stored in the log entry.
+
+ * The udev hwdb now contains DPI information for mice. For
+ details see:
+
+ http://who-t.blogspot.de/2014/12/building-a-dpi-database-for-mice.html
+
+ * 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.
+
+ * systemd-rfkill will no longer take the rfkill device name
+ into account when storing rfkill state on disk, as the name
+ might be dynamically assigned and not stable. Instead, the
+ ID_PATH udev variable combined with the rfkill type (wlan,
+ bluetooth, ...) is used.
+
+ * A new service systemd-machine-id-commit.service has been
+ added. When used on systems where /etc is read-only during
+ boot, and /etc/machine-id is not initialized (but an empty
+ file), this service will copy the temporary machine ID
+ created as replacement into /etc after the system is fully
+ booted up. This is useful for systems that are freshly
+ installed with a non-initialized machine ID, but should get
+ a fixed machine ID for subsequent boots.
+
+ * networkd's .netdev files now provide a large set of
+ configuration parameters for VXLAN devices. Similar, the
+ bridge port cost parameter is now configurable in .network
+ files. There's also new support for configuring IP source
+ routing. networkd .link files gained support for a new
+ OriginalName= match that is useful to match against the
+ original interface name the kernel assigned. .network files
+ may include MTU= and MACAddress= fields for altering the MTU
+ and MAC address while being connected to a specific network
+ interface.
+
+ * The LUKS logic gained supported for configuring
+ UUID-specific key files. There's also new support for naming
+ LUKS device from the kernel command line, using the new
+ luks.name= argument.
+
+ * Timer units may now be transiently created via the bus API
+ (this was previously already available for scope and service
+ units). In addition it is now possible to create multiple
+ transient units at the same time with a single bus call. The
+ "systemd-run" tool has been updated to make use of this for
+ running commands on a specified time, in at(1)-style.
+
+ * tmpfiles gained support for "t" lines, for assigning
+ extended attributes to files. Among other uses this may be
+ used to assign SMACK labels to files.

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.
