systemd System and Service Manager
+CHANGES WITH 204:
+
+ * The Python bindings gained some minimal support for the APIs
+ exposed by libsystemd-logind.
+
+ * ConditionSecurity= gained support for detecting SMACK. Since
+ this condition already supports SELinux and AppArmor we only
+ miss IMA for this. Patches welcome!

+
+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 are 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.

+
+CHANGES WITH 202:
+
+ * The output of 'systemctl list-jobs' got some polishing. The
+ '--type=' argument may now be passed more than once. A new
+ command 'systemctl list-sockets' has been added which shows
+ a list of kernel sockets systemd is listening on with the
+ socket units they belong to, plus the units these socket
+ units activate.
+
+ * The experimental libsystemd-bus library got substantial
+ updates to work in conjunction with the (also experimental)
+ kdbus kernel project. It works well enough to exchange
+ messages with some sophistication. Note that kdbus is not
+ ready yet, and the library is mostly an elaborate test case
+ for now, and not installable.
+
+ * systemd gained a new unit 'systemd-static-nodes.service'
+ that generates static device nodes earlier during boot, and
+ can run in conjunction with udev.
+
+ * libsystemd-login gained a new call sd_pid_get_user_unit()
+ to retrieve the user systemd unit a process is running
+ in. This is useful for systems where systemd is used as
+ session manager.
+
+ * systemd-nspawn now places all containers in the new /machine
+ top-level cgroup directory in the name=systemd
+ hierarchy. libvirt will soon do the same, so that we get a
+ uniform separation of /system, /user and /machine for system
+ services, user processes and containers/virtual
+ machines. This new cgroup hierarchy is also useful to stick
+ stable names to specific container instances, which can be
+ recognized later this way (this name may be controlled
+ via systemd-nspawn's new -M switch). libsystemd-login also
+ gained a new call sd_pid_get_machine_name() to retrieve the
+ name of the container/VM a specific process belongs to.
+
+ * bootchart can now store its data in the journal.
+
+ * libsystemd-journal gained a new call
+ sd_journal_add_conjunction() for AND expressions to the
+ matching logic. This can be used to express more complex
+ logical expressions.
+
+ * journactl can now take multiple --unit= and --user-unit=
+ switches.
+
+ * The cryptsetup logic now understands the "luks.key=" kernel
+ command line switch for specifying a file to read the
+ decryption key from. Also, if a configured key file is not
+ found the tool will now automatically fall back to prompting
+ the user.
+
+ * Python systemd.journal module was updated to wrap recently
+ added functions from libsystemd-journal. The interface was
+ changed to bring the low level interface in s.j._Reader
+ closer to the C API, and the high level interface in
+ s.j.Reader was updated to wrap and convert all data about
+ an entry.

+
+CHANGES WITH 201:
+
+ * journalctl --update-catalog now understands a new --root=
+ option to operate on catalogs found in a different root
+ directory.
+
+ * During shutdown after systemd has terminated all running
+ services a final killing loop kills all remaining left-over
+ processes. We will now print the name of these processes
+ when we send SIGKILL to them, since this usually indicates a
+ problem.
+
+ * If /etc/crypttab refers to password files stored on
+ configured mount points automatic dependencies will now be
+ generated to ensure the specific mount is established first
+ before the key file is attempted to be read.
+
+ * 'systemctl status' will now show information about the
+ network sockets a socket unit is listening on.
+
+ * 'systemctl status' will also shown information about any
+ drop-in configuration file for units. (Drop-In configuration
+ files in this context are files such as
+ /etc/systemd/systemd/foobar.service.d/*.conf)
+
+ * systemd-cgtop now optionally shows summed up CPU times of
+ cgroups. Press '%' while running cgtop to switch between
+ percentage and absolute mode. This is useful to determine
+ which cgroups use up the most CPU time over the entire
+ runtime of the system. systemd-cgtop has also been updated
+ to be 'pipeable' for processing with further shell tools.
+
+ * 'hostnamectl set-hostname' will now allow setting of FQDN
+ hostnames.
+
+ * The formatting and parsing of time span values has been
+ changed. The parser now understands fractional expressions
+ such as "5.5h". The formatter will now output fractional
+ expressions for all time spans under 1min, i.e. "5.123456s"
+ rather than "5s 123ms 456us". For time spans under 1s
+ millisecond values are shown, for those under 1ms
+ microsecond values are shown. This should greatly improve
+ all time-related output of systemd.
+
+ * libsystemd-login and libsystemd-journal gained new
+ functions for querying the poll() events mask and poll()
+ timeout value for integration into arbitrary event
+ loops.
+
+ * localectl gained the ability to list available X11 keymaps
+ (models, layouts, variants, options).
+
+ * 'systemd-analyze dot' gained the ability to filter for
+ specific units via shell-style globs, to create smaller,
+ more useful graphs. I.e. it's now possible to create simple
+ graphs of all the dependencies between only target units, or
+ of all units that Avahi has dependencies with.
