Security issues fixed:
CVE-2018-15688: A buffer overflow vulnerability in the dhcp6 client of
 systemd allowed a malicious dhcp6 server to overwrite heap memory in
 systemd-networkd. (bsc#1113632)

CVE-2018-15686: A vulnerability in unit_deserialize of systemd allows an
 attacker to supply arbitrary state across systemd re-execution via
 NotifyAccess. This can be used to improperly influence systemd execution
 and possibly lead to root privilege escalation. (bsc#1113665)

Non security issues fixed:
dhcp6: split assert_return() to be more debuggable when hit

core: skip unit deserialization and move to the next one when
 unit_deserialize() fails

core: properly handle deserialization of unknown unit types (#6476)

core: don't create Requires for workdir if 'missing ok' (bsc#1113083)

logind: use manager_get_user_by_pid() where appropriate

logind: rework manager_get_{user<pipe>session}_by_pid() a bit

login: fix [email protected] case, so we don't allow nested sessions (#8051)
 (bsc#1112024)

core: be more defensive if we can't determine per-connection socket peer
 (#7329)

core: introduce systemd.early_core_pattern= kernel cmdline option

core: add missing 'continue' statement

core/mount: fstype may be NULL

journald: don't ship systemd-journald-audit.socket (bsc#1109252)

core: make 'tmpfs' dependencies on swapfs a 'default' dep, not an
 'implicit' (bsc#1110445)

mount: make sure we unmount tmpfs mounts before we deactivate swaps
 (#7076)

detect-virt: do not try to read all of /proc/cpuinfo (bsc#1109197)

emergency: make sure console password agents don't interfere with the
 emergency shell

man: document that 'nofail' also has an effect on ordering

journald: take leading spaces into account in syslog_parse_identifier

journal: do not remove multiple spaces after identifier in syslog message

syslog: fix segfault in syslog_parse_priority()

journal: fix syslog_parse_identifier()

install: drop left-over debug message (#6913)

Ship systemd-sysv-install helper via the main package This script was
 part of systemd-sysvinit sub-package but it was wrong since
 systemd-sysv-install is a script used to redirect enable/disable
 operations to chkconfig when the unit targets are sysv init scripts.
 Therefore it's never been a SySV init tool.

Add udev.no-partlabel-links kernel command-line option. This option can
 be used to disable the generation of the by-partlabel symlinks
 regardless of the name used. (bsc#1089761)

man: SystemMaxUse= clarification in journald.conf(5). (bsc#1101040)

systemctl: load unit if needed in 'systemctl is-active' (bsc#1102908)

core: don't freeze OnCalendar= timer units when the clock goes back a
 lot (bsc#1090944)

Enable or disable machines.target according to the presets (bsc#1107941)

cryptsetup: add support for sector-size= option (fate#325697)

nspawn: always use permission mode 555 for /sys ... [Please see the references for more information on the vulnerabilities]");
