This allows the manager to show the + internal state of daemons and closes a race condition + when the process is still running but has closed its + d-bus connection. + + * Services with Type=oneshot do not have to have any + ExecStart commands. + + * User units are now loaded also from + $XDG_RUNTIME_DIR/systemd/user/. This is similar to the + /run/systemd/user directory that was already previously + supported, but is under the control of the user. + + * A timeout for the start of the system can be configured. The + system can be configured to reboot or poweroff if the basic + system default target is not reached before the timeout (new + StartTimeoutSec=, StartTimeoutAction=, + StartTimeoutRebootArgument= options). + + * systemd-logind can be configured to also handle lid switch + events even when the machine is docked or multiple displays + are attached (HandleLidSwitchDocked= option). + + * A helper binary and a service have been added which can be + used to resume from hibernation in the initramfs. A + generator will parse the resume= option on the kernel + command-line to trigger resume. + + * A user console daemon systemd-consoled has been added. It is + a preview, and will so far open a single terminal on each + session of the user marked as Desktop=SYSTEMD-CONSOLE. + + * Route metrics can be specified for DHCP routes added by + systemd-networkd. + + * SELinux context of socket-actived services can be set from + the information provided by the remote peer + (SELinuxContextFromNet= option). + + * Userspace firmware loading support has been removed and + the minimum supported kernel version is thus bumped to 3.7. + + * Timeout for udev workers has been increased from 1 to 3 + minutes, but a warning will be printed after 1 minute to + help diagnose kernel modules that take a long time to load. + + * Udev rules can now remove tags with TAG-="foobar". + + * Readhead implementation has been removed. In many + circumstatances it didn't give expected benefits even for + rotational disk drives and was becoming less relevant in the + age of SSDs. + + * Swap units can use Discard= to specify discard options. + Discard options specified for swaps in /etc/fstab are now + respected. + + * Docker containers are now detected as a separate type of + virtualization. + + * The Password Agent protocol gained support for queries where + the user input is shown, useful e.g. for usernames. + systemd-ask-password gained a new --echo option to turn + that on. + + * The default sysctl.d/ snippets will now set: + + net.core.default_qdisc = fq_codel + + This selects Fair Queueing Controlled Delay as the default + queueing discipline for network interfaces. fq_codel helps + fight the network bufferbloat problem. It is believed to be + a good default with no tuning required for most workloads. + Downstream distributions may override this choice. On 10Gbit + servers that do not do forwarding, "fq" may perform better. + Systems without a good clocksource should use "pfifo_fast". + CHANGES WITH 216: - * timedated does no longer read NTP unit names from + + * timedated no longer reads NTP implementation unit names from /usr/lib/systemd/ntp-units.d/*.list.

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 unprivileged + 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 can be used + instead 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 simultaneously 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-networkd 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 friendly + 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 learned 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. There are also new configuration options to + configure the vendor client identifier and broadcast mode + for DHCP. + + * 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. + + * systemd-networkd's DHCP client will no longer request + broadcasting by default, as this tripped up some networks. + For hardware where broadcast is required the feature should + be switched back on using RequestBroadcast=yes. + + * systemd-networkd will now set up IPv4LL addresses (when + enabled) even if DHCP is configured successfully. + + * udev will now default to respect network device names given + by the kernel when the kernel indicates that these are + predictable. This behavior can be tweaked by changing + NamePolicy= in the relevant .link file. + + * 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-existent 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) interactively on first + boot. Alternatively it may also be used to provision these + things offline on OS images installed into directories. + + * The default sysctl.d/ snippets will now set + + net.ipv4.conf.default.promote_secondaries=1 + + This has the benefit of no flushing secondary IP addresses + when primary addresses are removed. + + Contributions from: Ansgar Burchardt, Bastien Nocera, Colin + Walters, Dan Dedrick, Daniel Buch, Daniel Korostil, Daniel + Mack, Dan Williams, Dave Reisner, David Herrmann, Denis + Kenzior, Eelco Dolstra, Eric Cook, Hannes Reinecke, Harald + Hoyer, Hong Shick Pak, Hui Wang, Jean-André Santoni, Jóhann + B.
