systemd System and Service Manager
+CHANGES WITH 203:
+
+ * systemd-nspawn will now create /etc/resolv.conf if
+ necessary, before bind-mounting the host's file onto it.
+
+ * systemd-nspawn will now store meta information about a
+ container on the container's cgroup as extended attribute
+ fields, including the root directory.
+
+ * The cgroup hierarchy has been reworked in many ways. All
+ objects any of the components systemd creates in the cgroup
+ tree is now suffixed. More specifically, user sessions are
+ now placed in cgroups suffixed with ".session", users in
+ cgroups suffixed with ".user", and nspawn containers in
+ cgroups suffixed with ".nspawn". Furthermore, all cgroup
+ names are now escaped in a simple scheme to avoid collision
+ of userspace object names with kernel filenames. This work
+ is preparation for making these objects relocatable in the
+ cgroup tree, in order to allow easy resource partitioning of
+ these objects without causing naming conflicts.
+
+ * systemctl list-dependencies gained the new switches
+ --plain, --reverse, --after and --before.
+
+ * systemd-inhibit now shows the process name of processes that
+ have taken an inhibitor lock.
+
+ * nss-myhostname will now also resolve "localhost"
+ implicitly. This makes /etc/hosts an optional file and
+ nicely handles that on IPv6 ::1 maps to both "localhost" and
+ the local hostname.
+
+ * libsystemd-logind.so gained a new call
+ sd_get_machine_names() to enumerate running containers and
+ VMs (currently only supported by very new libvirt and
+ nspawn). sd_login_monitor can now be used to watch
+ VMs/containers coming and going.
+
+ * .include is not allowed recursively anymore, and only in
+ unit files. Usually it is better to use drop-in snippets in
+ .d/*.conf anyway, as introduced with systemd 198.
+
+ * systemd-analyze gained a new "critical-chain" command that
+ determines the slowest chain of units run during system
+ boot-up. It is very useful for tracking down where
+ optimizing boot time is the most beneficial.
+
+ * systemd will no longer allow manipulating service paths in
+ the name=systemd:/system cgroup tree using ControlGroup= in
+ units. (But is still fine with it in all other dirs.)
+
+ * There's a new systemd-nspawn@.service service file that may
+ be used to easily run nspawn containers as system
+ services. With the container's root directory in
+ /var/lib/container/foobar it is now sufficient to run
+ "systemctl start systemd-nspawn@foobar.service" to boot it.
+
+ * systemd-cgls gained a new parameter "--machine" to list only
+ the processes within a certain container.
+
+ * ConditionSecurity= now can check for "apparmor". We still
+ are lacking checks for SMACK and IMA for this condition
+ check though. Patches welcome!
+
+ * A new configuration file /etc/systemd/sleep.conf has been
+ added that may be used to configure which kernel operation
+ systemd is supposed to execute when "suspend", "hibernate"
+ or "hybrid-sleep" is requested. This makes the new kernel
+ "freeze" state accessible to the user.
+
+ * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape
+ the passed argument if applicable.
