systemd System and Service Manager
+CHANGES WITH 211:
+
+ * A new unit file setting RestrictAddressFamilies= has been
+ added to restrict which socket address families unit
+ processes gain access to. This takes address family names
+ like "AF_INET" or "AF_UNIX", and is useful to minimize the
+ attack surface of services via exotic protocol stacks. This
+ is built on seccomp system call filters.
+
+ * Two new unit file settings RuntimeDirectory= and
+ RuntimeDirectoryMode= have been added that may be used to
+ manage a per-daemon runtime directories below /run. This is
+ an alternative for setting up directory permissions with
+ tmpfiles snippets, and has the advantage that the runtime
+ directory's lifetime is bound to the daemon runtime and that
+ the daemon starts up with an empty directory each time. This
+ is particularly useful when writing services that drop
+ priviliges using the User= or Group= setting.
+
+ * The DeviceAllow= unit setting now supports globbing for
+ matching against device group names.
+
+ * The systemd configuration file system.conf gained new
+ settings DefaultCPUAccounting=, DefaultBlockIOAccounting=,
+ DefaultMemoryAccounting= to globally turn on/off accounting
+ for specific resources (cgroups) for all units. These
+ settings may still be overridden individually in each unit
+ though.
+
+ * systemd-gpt-auto-generator is now able to discover /srv and
+ root partitions in addition to /home and swap partitions. It
+ also supports LUKS-encrypted partitions now. With this in
+ place automatic discovery of partitions to mount following
+ the Discoverable Partitions Specification
+ (http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec)
+ is now a lot more complete. This allows booting without
+ /etc/fstab and without root= on the kernel command line on
+ appropriately prepared systems.
+
+ * systemd-nspawn gained a new --image= switch which allows
+ booting up disk images and Linux installations on any block
+ device that follow the Discoverable Partitions Specification
+ (see above). This means that installations made with
+ appropriately updated installers may now be started and
+ deployed using container managers, completely
+ unmodified. (We hope that libvirt-lxc will add support for
+ this feature soon, too.)
+
+ * systemd-nspawn gained a new --network-macvlan= setting to
+ set up a private macvlan interface for the
+ container. Similar, systemd-networkd gained a new
+ Kind=macvlan setting in .netdev files.
+
+ * systemd-networkd now supports configuring local addresses
+ using IPv4LL.
+
+ * A new tool systemd-network-wait-online has been added to
+ synchronously wait for network connectivity using
+ systemd-networkd.
+
+ * The sd-bus.h bus API gained a new sd_bus_track object for
+ tracking the life-cycle of bus peers. Note that sd-bus.h is
+ still not a public API though (unless you specify
+ --enable-kdbus on the configure command line, which however
+ voids your warranty and you get no API stability guarantee).
+
+ * The $XDG_RUNTIME_DIR runtime directories for each user are
+ now individual tmpfs instances, which has the benefit of
+ introducing separate pools for each user, with individual
+ size limits, and thus making sure that unprivileged clients
+ can no longer negatively impact the system or other users by
+ filling up their $XDG_RUNTIME_DIR. A new logind.conf setting
+ RuntimeDirectorySize= has been introduced that allows
+ controlling the default size limit for all users. It
+ defaults to 10% of the available physical memory. This is no
+ replacement for quotas on tmpfs though (which the kernel
+ still does not support), as /dev/shm and /tmp are still
+ shared resources used by both the system and unprivileged
+ users.
+
+ * logind will now automatically turn off automatic suspending
+ on laptop lid close when more than one display is
+ connected. This was previously expected to be implemented
+ individually in desktop environments (such as GNOME),
+ however has been added to logind now, in order to fix a
+ boot-time race where a desktop environment might not have
+ been started yet and thus not been able to take an inhibitor
+ lock at the time where logind already suspends the system
+ due to a closed lid.
+
+ * logind will now wait at least 30s after each system
+ suspend/resume cycle, and 3min after system boot before
+ suspending the system due to a closed laptop lid. This
+ should give USB docking stations and similar enough time to
+ be probed and configured after system resume and boot in
+ order to then act as suspend blocker.
+
+ * systemd-run gained a new --property= setting which allows
+ initialization of resource control properties (and others)
+ for the created scope or service unit. Example: "systemd-run
+ --property=BlockIOWeight=10 updatedb" may be used to run
+ updatedb at a low block IO scheduling weight.
+
+ * systemd-run's --uid=, --gid=, --setenv=, --setenv= switches
+ now also work in --scope mode.
+
+ * When systemd is compiled with kdbus support, basic support
+ for enforced policies is now in place. (Note that enabling
+ kdbus still voids your warranty and no API compatibility
+ promises are made.)

CHANGES WITH 210:
* systemd will now relabel /dev after loading the SMACK policy
according to SMACK rules.
- * A new unit file option AppArmoreProfile= has been added to
+ * A new unit file option AppArmorProfile= has been added to
set the AppArmor profile for the processes of a unit.
* A new condition check ConditionArchitecture= has been added
* logind will now watch SW_DOCK switches and inhibit reaction
to the lid switch if it is pressed. This means that logind
will not suspend the machine anymore if the lid is closed
- and the systemd is docked, if the laptop supports SW_DOCK
+ and the system is docked, if the laptop supports SW_DOCK
notifications via the input layer. Note that ACPI docking
stations do not generate this currently. Also note that this
logic is usually not fully sufficient and Desktop
IFUNC. Please make sure to use --enable-compat-libs only
during a transitional period!
