systemd System and Service Manager
+CHANGES WITH 188:
+
+ * When running in --user mode systemd will now become a
+ subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps
+ tree a lot more organized.
+
+ * A new PartOf= unit dependency type has been introduced that
+ may be used to group services in a natural way.
+
+ * "systemctl enable" may now be used to enable instances of
+ services.
+
+ * journalctl now prints error log levels in red, and
+ warning/notice log levels in bright white. It also supports
+ filtering by log level now.
+
+ * cgtop gained a new -n switch (similar to top), to configure
+ the maximum number of iterations to run for. It also gained
+ -b, to run in batch mode (accepting no input).
+
+ * The suffix ".service" may now be ommited on most systemctl
+ command lines involving service unit names.
+
+ * There's a new bus call in logind to lock all sessions, as
+ well as a loginctl verb for it "lock-sessions".
+
+ * libsystemd-logind.so gained a new call sd_journal_perror()
+ that works similar to libc perror() but logs to the journal
+ and encodes structured information about the error number.
+
+ * /etc/crypttab entries now understand the new keyfile-size=
+ option.
+
+ * shutdown(8) now can send a (configurable) wall message when
+ a shutdown is cancelled.
+
+ * The mount propagation mode for the root file system will now
+ default to "shared", which is useful to make containers work
+ nicely out-of-the-box so that they receive new mounts from
+ the host. This can be undone locally by running "mount
+ --make-rprivate /" if needed.
+
+ * The prefdm.service file has been removed. Distributions
+ should maintain this unit downstream if they intend to keep
+ it around. However, we recommend writing normal unit files
+ for display managers instead.
+
+ * Since systemd is a crucial part of the OS we will now
+ default to a number of compiler switches that improve
+ security (hardening) such as read-only relocations, stack
+ protection, and suchlike.
+
+ * The TimeoutSec= setting for services is now split into
+ TimeoutStartSec= and TimeoutStopSec= to allow configuration
+ of individual time outs for the start and the stop phase of
+ the service.

+
+CHANGES WITH 187:
+
+ * The journal and id128 C APIs are now fully documented as man
+ pages.
+
+ * Extra safety checks have been added when transitioning from
+ the initial RAM disk to the main system to avoid accidental
+ data loss.
+
+ * /etc/crypttab entries now understand the new keyfile-offset=
+ option.
+
+ * systemctl -t can now be used to filter by unit load state.
+
+ * The journal C API gained the new sd_journal_wait() call to
+ make writing synchronous journal clients easier.
+
+ * journalctl gained the new -D switch to show journals from a
+ specific directory.
+
+ * journalctl now displays a special marker between log
+ messages of two different boots.
+
+ * The journal is now explicitly flushed to /var via a service
+ systemd-journal-flush.service, rather than implicitly simply
+ by seeing /var/log/journal to be writable.
+
+ * journalctl (and the journal C APIs) can now match for much
+ more complex expressions, with alternatives and
+ disjunctions.
+
+ * When transitioning from the initial RAM disk to the main
+ system we will now kill all processes in a killing spree to
+ ensure no processes stay around by accident.
+
+ * Three new specifiers may be used in unit files: %u, %h, %s
+ resolve to the user name, user home directory resp. user
+ shell. This is useful for running systemd user instances.
+
+ * We now automatically rotate journal files if their data
+ object hash table gets a fill level > 75%. We also size the
+ hash table based on the configured maximum file size. This
+ together should lower hash collisions drastically and thus
+ speed things up a bit.
+
+ * journalctl gained the new "--header" switch to introspect
+ header data of journal files.
+
+ * A new setting SystemCallFilters= has been added to services
+ which may be used to apply blacklists or whitelists to
+ system calls. This is based on SECCOMP Mode 2 of Linux 3.5.
+
+ * nspawn gained a new --link-journal= switch (and quicker: -j)
+ to link the container journal with the host. This makes it
+ very easy to centralize log viewing on the host for all
+ guests while still keeping the journal files separated.
+
+ * Many bugfixes and optimizations

+
+CHANGES WITH 186:
+
+ * Several tools now understand kernel command line arguments,
+ which are only read when run in an initial RAM disk. They
+ usually follow closely their normal counterparts, but are
+ prefixed with rd.
+
+ * There's a new tool to analyze the readahead files that are
+ automatically generated at boot. Use:
+
+ /usr/lib/systemd/systemd-readahead analyze /.readahead
+
+ * We now provide an early debug shell on tty9 if this enabled. Use:
+
+ systemctl enable debug-shell.service
+
+ * All plymouth related units have been moved into the Plymouth
+ package. Please make sure to upgrade your Plymouth version
+ as well.
+
+ * systemd-tmpfiles now supports getting passed the basename of
+ a configuration file only, in which case it will look for it
+ in all appropriate directories automatically.
+
+ * udevadm info now takes a /dev or /sys path as argument, and
+ does the right thing. Example:
+
+ udevadm info /dev/sda
+ udevadm info /sys/class/block/sda
+
+ * systemctl now prints a warning if a unit is stopped but a
+ unit that might trigger it continues to run. Example: a
+ service is stopped but the socket that activates it is left
+ running.
+
+ * "systemctl status" will now mention if the log output was
+ shortened due to rotation since a service has been started.
+
+ * The journal API now exposes functions to determine the
+ "cutoff" times due to rotation.
+
+ * journald now understands SIGUSR1 and SIGUSR2 for triggering
+ immediately flushing of runtime logs to /var if possible,
+ resp. for triggering immediate rotation of the journal
+ files.
+
+ * It is now considered an error if a service is attempted to
+ be stopped that is not loaded.
+
+ * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames.
+
+ * systemd-analyze now supports Python 3
+
+ * tmpfiles now supports cleaning up directories via aging
+ where the first level dirs are always kept around but
+ directories beneath it automatically aged. This is enabled
+ by prefixing the age field with '~'.
+
+ * Seat objects now expose CanGraphical, CanTTY properties
+ which is required to deal with very fast bootups where the
+ display manager might be running before the graphics drivers
+ completed initialization.
+
+ * Seat objects now expose a State property.
+
+ * We now include RPM macros for service enabling/disabling
+ based on the preset logic. We recommend RPM based
+ distributions to make use of these macros if possible. This
+ makes it simpler to reuse RPM spec files across
+ distributions.
+
+ * We now make sure that the collected systemd unit name is
+ always valid when services log to the journal via
+ STDOUT/STDERR.
+
+ * There's a new man page kernel-command-line(7) detailing all
+ command line options we understand.
+
+ * The fstab generator may now be disabled at boot by passing
+ fstab=0 on the kernel command line.
+
+ * A new kernel command line option modules-load= is now understood
+ to load a specific kernel module statically, early at boot.
+
+ * Unit names specified on the systemctl command line are now
+ automatically escaped as needed. Also, if file system or
+ device paths are specified they are automatically turned
+ into the appropriate mount or device unit names. Example:
+
+ systemctl status /home
+ systemctl status /dev/sda
+
+ * The SysVConsole= configuration option has been removed from
+ system.conf parsing.
+
+ * The SysV search path is no longer exported on the D-Bus
+ Manager object.
+
+ * The Names= option is been removed from unit file parsing.
+
+ * There's a new man page bootup(7) detailing the boot process.
+
+ * Every unit and every generator we ship with systemd now
+ comes with full documentation. The self-explanatory boot is
+ complete.
+
+ * A couple of services gained "systemd-" prefixes in their
+ name if they wrap systemd code, rather than only external
+ code. Among them fsck@.service which is now
+ systemd-fsck@.service.
+
+ * The HaveWatchdog property has been removed from the D-Bus
+ Manager object.
+
+ * systemd.confirm_spawn= on the kernel command line should now
+ work sensibly.
+
+ * There's a new man page crypttab(5) which details all options
+ we actually understand.
+
+ * systemd-nspawn gained a new --capability= switch to pass
+ additional capabilities to the container.
+
+ * timedated will now read known NTP implementation unit names
+ from /usr/lib/systemd/ntp-units.d/*.list,
+ systemd-timedated-ntp.target has been removed.
+
+ * journalctl gained a new switch "-b" that lists log data of
+ the current boot only.
+
+ * The notify socket is in the abstract namespace again, in
+ order to support daemons which chroot() at start-up.
+
+ * There is a new Storage= configuration option for journald
+ which allows configuration of where log data should go. This
+ also provides a way to disable journal logging entirely, so
+ that data collected is only forwarded to the console, the
+ kernel log buffer or another syslog implementation.
+
+ * Many bugfixes and optimizations

+
+CHANGES WITH 185:
+ * "systemctl help <unit>" now shows the man page if one is
+ available.
+
+ * Several new man pages have been added.
+
+ * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=,
+ MaxLevelConsole= can now be specified in
+ journald.conf. These options allow reducing the amount of
+ data stored on disk or forwarded by the log level.
+
+ * TimerSlackNSec= can now be specified in system.conf for
+ PID1. This allows system-wide power savings.

+
+CHANGES WITH 184:
+ * logind is now capable of (optionally) handling power and
+ sleep keys as well as the lid switch.
+
+ * journalctl now understands the syntax "journalctl
+ /usr/bin/avahi-daemon" to get all log output of a specific
+ daemon.
+
+ * CapabilityBoundingSet= in system.conf now also influences
+ the capability bound set of usermode helpers of the kernel.

CHANGES WITH 183:
* Note that we skipped 139 releases here in order to set the
new version to something that is greater than both udev's
to be used as drop-in files.
* systemd and logind now handle system sleep states, in
- particulary suspending and hibernating.
+ particular suspending and hibernating.
* logind now implements a sleep/shutdown/idle inhibiting logic
suitable for a variety of uses. Soonishly Lennart will blog
* The GTK tools have been split off into a systemd-ui.
