+ to their unit files to take over and replace systemd's NTP
+ default functionality.
+
+ * systemd-sysusers gained a new line type "r" for configuring
+ which UID/GID ranges to allocate system users/groups
+ from. Lines of type "u" may now add an additional column
+ that specifies the home directory for the system user to be
+ created. Also, systemd-sysusers may now optionally read user
+ information from STDIN instead of a file. This is useful for
+ invoking it from RPM preinst scriptlets that need to create
+ users before the first RPM file is installed since these
+ files might need to be owned by them. A new
+ %sysusers_create_inline RPM macro has been introduced to do
+ just that. systemd-sysusers now updates the shadow files as
+ well as the user/group databases, which should enhance
+ compatibility with certain tools like grpck.
+
+ * A number of bus APIs of PID 1 now optionally consult
+ PolicyKit to permit access for otherwise unpriviliged
+ clients under certain conditions. Note that this currently
+ doesn't support interactive authentication yet, but this is
+ expected to be added eventually, too.
+
+ * /etc/machine-info now has new fields for configuring the
+ deployment environment of the machine, as well as the
+ location of the machine. hostnamectl has been updated with
+ new command to update these fields.
+
+ * systemd-timesyncd has been updated to automatically acquire
+ NTP server information from systemd-networkd, which might
+ have been discovered via DHCP.
+
+ * systemd-resolved now includes a caching DNS stub resolver
+ and a complete LLMNR name resolution implementation. A new
+ NSS module "nss-resolve" has been added which make be used
+ of glibc's own "nss-dns" to resolve hostnames via
+ systemd-resolved. Hostnames, addresses and arbitrary RRs may
+ be resolved via systemd-resolved D-Bus APIs. In contrast to
+ the glibc internal resolver systemd-resolved is aware of
+ multi-homed system, and keeps DNS server and caches separate
+ and per-interface. Queries are sent simultaneous on all
+ interfaces that have DNS servers configured, in order to
+ properly handle VPNs and local LANs which might resolve
+ separate sets of domain names. systemd-resolved may acquire
+ DNS server information from systemd-resolved automatically,
+ which in turn might have discovered them via DHCP. A tool
+ "systemd-resolve-host" has been added that may be used to
+ query the DNS logic in resolved. systemd-resolved implements
+ IDNA and automatically uses IDNA or UTF-8 encoding depending
+ on whether classic DNS or LLMNR is used as transport. In the
+ next releases we intend to add a DNSSEC and mDNS/DNS-SD
+ implementation to systemd-resolved.
+
+ * A new NSS module nss-mymachines has been added, that
+ automatically resolves the names of all local registered
+ containers to their respective IP addresses.
+
+ * A new client tool "networkctl" for systemd-networkd has been
+ added. It currently is entirely passive and will query
+ networking configuration from udev, rtnetlink and networkd,
+ and present it to the user in a very friendy
+ way. Eventually, we hope to extend it to become a full
+ control utility for networkd.
+
+ * .socket units gained a new DeferAcceptSec= setting that
+ controls the kernels' TCP_DEFER_ACCEPT sockopt for
+ TCP. Similar, support for controlling TCP keep-alive
+ settings has been added (KeepAliveTimeSec=,
+ KeepAliveIntervalSec=, KeepAliveProbes=). Also, support for
+ turning off Nagle's algorithm on TCP has been added
+ (NoDelay=).
+
+ * logind learnt a new session type "web", for use in projects
+ like Cockpit which register web clients as PAM sessions.
+
+ * timer units with at least one OnCalendar= setting will now
+ be started only after timer-sync.target has been
+ reached. This way they will not elapse before the system
+ clock has been corrected by a local NTP client or
+ similar. This is particular useful on RTC-less embedded
+ machines, that come up with an invalid system clock.
+
+ * systemd-nspawn's --network-veth= switch should now result in
+ stable MAC addresses for both the outer and the inner side
+ of the link.
+
+ * systemd-nspawn gained a new --volatile= switch for running
+ container instances with /etc or /var unpopulated.
+
+ * The kdbus client code has been updated to use the new Linux
+ 3.17 memfd subsystem instead of the old kdbus-specific one.
+
+ * systemd-networkd's DHCP client and server now support
+ FORCERENEW.
+
+ * systemd will no longer inform the kernel about the current
+ timezone, as this is necessarily incorrect and racy as the
+ kernel has no understanding of DST and similar
+ concepts. This hence means FAT timestamps will be always
+ considered UTC, similar to what Android is already
+ doing. Also, when the RTC is configured to the local time
+ (rather than UTC) systemd will never synchronize back to it,
+ as this might confuse Windows at a later boot.
+
+ * systemd-analyze gained a new command "verify" for offline
+ validation of unit files.
+
+ * systemd-networkd gained support for a couple of additional
+ settings for bonding networking setups. Also, the metric for
+ statically configured routes may now be configured. For
+ network interfaces where this is appropriate the peer IP
+ address may now be configured.
+
+ * A new library systemd-terminal has been added that
+ implements full TTY stream parsing and rendering. This
+ library is supposed to be used later on for implementing a
+ full userspace VT subsystem, replacing the current kernel
+ implementation.
+
+ * A new tool systemd-journal-upload has been added to push
+ journal data to a remote system running
+ systemd-journal-remote.
+
+ * journald will no longer forward all local data to another
+ running syslog daemon. This change has been made because
+ rsyslog (which appears to be the most commonly used syslog
+ implementation these days) no longer makes use of this, and
+ instead pulls the data out of the journal on its own. Since
+ forwarding the messages to a non-existant syslog server is
+ more expensive than we assumed we have now turned this
+ off. If you run a syslog server that is not a recent rsyslog
+ version, you have to turn this option on again
+ (ForwardToSyslog= in journald.conf).
+
+ * journald now optionally supports the LZ4 compressor for
+ larger journal fields. This compressor should perform much
+ better than XZ which was the previous default.
+
+ * machinectl now shows the IP addresses of local containers,
+ if it knows them, plus the interface name of the container.
+
+ * A new tool "systemd-escape" has been added that makes it
+ easy to escape strings to build unit names and similar.
+
+ * sd_notify() messages may now include a new ERRNO= field
+ which is parsed and collected by systemd and shown among the
+ "systemctl status" output for a service.
+
+ * A new component "systemd-firstboot" has been added that
+ queries the most basic systemd information (timezone,
+ hostname, root password) inertactively on first
+ boot. Alternatively it may also be used to provision these
+ things offline on OS images installed into directories.
