systemd System and Service Manager
+CHANGES WITH 195:
+
+ * journalctl gained new --since= and --until= switches to
+ filter by time. It also now supports nice filtering for
+ units via --unit=/-u.
+
+ * Type=oneshot services may use ExecReload= and do the
+ right thing.
+
+ * The journal daemon now supports time-based rotation and
+ vacuuming, in addition to the usual disk-space based
+ rotation.
+
+ * The journal will now index the available field values for
+ each field name. This enables clients to show pretty drop
+ downs of available match values when filtering. The bash
+ completion of journalctl has been updated
+ accordingly. journalctl gained a new switch -F to list all
+ values a certain field takes in the journal database.
+
+ * More service events are now written as structured messages
+ to the journal, and made recognizable via message IDs.
+
+ * The timedated, localed and hostnamed mini-services which
+ previously only provided support for changing time, locale
+ and hostname settings from graphical DEs such as GNOME now
+ also have a minimal (but very useful) text-based client
+ utility each. This is probably the nicest way to changing
+ these settings from the command line now, especially since
+ it lists available options and is fully integrated with bash
+ completion.
+
+ * There's now a new tool "systemd-coredumpctl" to list and
+ extract coredumps from the journal.
+
+ * We now install a README each in /var/log/ and
+ /etc/rc.d/init.d explaining where the system logs and init
+ scripts went. This hopefully should help folks who go to
+ that dirs and look into the otherwise now empty void and
+ scratch their heads.
+
+ * When user-services are invoked (by systemd --user) the
+ $MANAGERPID env var is set to the PID of systemd.
+
+ * SIGRTMIN+24 when sent to a --user instance will now result
+ in immediate termination of systemd.
+
+ * gatewayd received numerous feature additions such as a
+ "follow" mode, for live syncing and filtering.
+
+ * browse.html now allows filtering and showing detailed
+ information on specific entries. Keyboard navigation and
+ mouse screen support has been added.
+
+ * gatewayd/journalctl now supports HTML5/JSON
+ Server-Sent-Events as output.
+
+ * The SysV init script compatibility logic will now
+ heuristically determine whether a script supports the
+ "reload" verb, and only then make this available as
+ "systemctl reload".
+
+ * "systemctl status --follow" has been removed, use "journalctl
+ -u" instead.
+
+ * journald.conf's RuntimeMinSize=, PersistentMinSize= settings
+ have been removed since they are hardly useful to be
+ configured.
+
+ * And I'd like to take the opportunity to specifically mention
+ Zbigniew for his great contributions. Zbigniew, you rock!

+
+CHANGES WITH 194:
+
+ * If /etc/vconsole.conf is non-existent or empty we will no
+ longer load any console font or key map at boot by
+ default. Instead the kernel defaults will be left
+ intact. This is definitely the right thing to do, as no
+ configuration should mean no configuration, and hard-coding
+ font names that are different on all archs is probably a bad
+ idea. Also, the kernel default key map and font should be
+ good enough for most cases anyway, and mostly identical to
+ the userspace fonts/key maps we previously overloaded them
+ with. If distributions want to continue to default to a
+ non-kernel font or key map they should ship a default
+ /etc/vconsole.conf with the appropriate contents.

+
+CHANGES WITH 193:
+
+ * journalctl gained a new --cursor= switch to show entries
+ starting from the specified location in the journal.
+
+ * We now enforce a size limit on journal entry fields exported
+ with "-o json" in journalctl. Fields larger than 4K will be
+ assigned null. This can be turned off with --all.
+
+ * An (optional) journal gateway daemon is now available as
+ "systemd-journal-gatewayd.service". This service provides
+ access to the journal via HTTP and JSON. This functionality
+ will be used to implement live log synchronization in both
+ pull and push modes, but has various other users too, such
+ as easy log access for debugging of embedded devices. Right
+ now it is already useful to retrieve the journal via HTTP:
+
+ # systemctl start systemd-journal-gatewayd.service
+ # wget http://localhost:19531/entries
+
+ This will download the journal contents in a
+ /var/log/messages compatible format. The same as JSON:
+
+ # curl -H"Accept: application/json" http://localhost:19531/entries
+
+ This service is also accessible via a web browser where a
+ single static HTML5 app is served that uses the JSON logic
+ to enable the user to do some basic browsing of the
+ journal. This will be extended later on. Here's an example
+ screenshot of this app in its current state:

+
+CHANGES WITH 192:
+
+ * The bash completion logic is now available for journalctl
+ too.
+
+ * We don't mount the "cpuset" controller anymore together with
+ "cpu" and "cpuacct", as "cpuset" groups generally cannot be
+ started if no parameters are assigned to it. "cpuset" hence
+ broke code that assumed it it could create "cpu" groups and
+ just start them.
+
+ * journalctl -f will now subscribe to terminal size changes,
+ and line break accordingly.
+
+ Contributions from: Dave Reisner, Kay Sievers, Lennart
+ Poettering, Lukas Nykrynm, Mirco Tischler, Václav Pavlín
+
+CHANGES WITH 191:
+
+ * nspawn will now create a symlink /etc/localtime in the
+ container environment, copying the host's timezone
+ setting. Previously this has been done via a bind mount, but
+ since symlinks cannot be bind mounted this has now been
+ changed to create/update the appropriate symlink.
+
+ * journalctl -n's line number argument is now optional, and
+ will default to 10 if omitted.
+
+ * journald will now log the maximum size the journal files may
+ take up on disk. This is particularly useful if the default
+ built-in logic of determining this parameter from the file
+ system size is used. Use "systemctl status
+ systemd-journald.service" to see this information.
+
+ * The multi-seat X wrapper tool has been stripped down. As X
+ is now capable of enumerating graphics devices via udev in a
+ seat-aware way the wrapper is not strictly necessary
+ anymore. A stripped down temporary stop-gap is still shipped
+ until the upstream display managers have been updated to
+ fully support the new X logic. Expect this wrapper to be
+ removed entirely in one of the next releases.
+
+ * HandleSleepKey= in logind.conf has been split up into
+ HandleSuspendKey= and HandleHibernateKey=. The old setting
+ is not available anymore. X11 and the kernel are
+ distuingishing between these keys and we should too. This
+ also means the inhibition lock for these keys has been split
+ into two.

+
+CHANGES WITH 190:
+
+ * Whenever a unit changes state we'll now log this to the
+ journal and show along the unit's own log output in
+ "systemctl status".
+
+ * ConditionPathIsMountPoint= can now properly detect bind
+ mount points too. (Previously, a bind mount of one file
+ system to another place in the same file system could not be
+ detected as mount, since they shared struct stat's st_dev
+ field.)
+
+ * We will now mount the cgroup controllers cpu, cpuacct,
+ cpuset and the controllers net_cls, net_prio together by
+ default.
+
+ * nspawn containers will now have a virtualized boot
+ ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted
+ over with a randomized ID at container initialization). This
+ has the effect of making "journalctl -b" do the right thing
+ in a container.
+
+ * The JSON output journal serialization has been updated not
+ to generate "endless" list objects anymore, but rather one
+ JSON object per line. This is more in line how most JSON
+ parsers expect JSON objects. The new output mode
+ "json-pretty" has been added to provide similar output, but
+ neatly aligned for readability by humans.
+
+ * We dropped all explicit sync() invocations in the shutdown
+ code. The kernel does this implicitly anyway in the kernel
+ reboot() syscall. halt(8)'s -n option is now a compatibility
+ no-op.
+
+ * We now support virtualized reboot() in containers, as
+ supported by newer kernels. We will fall back to exit() if
+ CAP_SYS_REBOOT is not available to the container. Also,
+ nspawn makes use of this now and will actually reboot the
+ container if the containerized OS asks for that.
+
+ * journalctl will only show local log output by default
+ now. Use --merge (-m) to show remote log output, too.
+
+ * libsystemd-journal gained the new sd_journal_get_usage()
+ call to determine the current disk usage of all journal
+ files. This is exposed in the new "journalctl --disk-usage"
+ command.
+
+ * journald gained a new configuration setting SplitMode= in
+ journald.conf which may be used to control how user journals
+ are split off. See journald.conf(5) for details.
+
+ * A new condition type ConditionFileNotEmpty= has been added.
+
+ * tmpfiles' "w" lines now support file globbing, to write
+ multiple files at once.
+
+ * We added Python bindings for the journal submission
+ APIs. More Python APIs for a number of selected APIs will
+ likely follow. Note that we intend to add native bindings
+ only for the Python language, as we consider it common
+ enough to deserve bindings shipped within systemd. There are
+ various projects outside of systemd that provide bindings
+ for languages such as PHP or Lua.
+
+ * Many conditions will now resolve specifiers such as %i. In
+ addition, PathChanged= and related directives of .path units
+ now support specifiers as well.
+
+ * There's now a new RPM macro definition for the system preset
+ dir: %_presetdir.
+
+ * journald will now warn if it can't foward a message to the
+ syslog daemon because it's socket is full.
+
+ * timedated will no longer write or process /etc/timezone,
+ except on Debian. As we do not support late mounted /usr
+ anymore /etc/localtime always being a symlink is now safe,
+ and hence the information in /etc/timezone is not necessary
+ anymore.
+
+ * logind will now always reserve one VT for a text getty (VT6
+ by default). Previously if more than 6 X sessions where
+ started they took up all the VTs with auto-spawned gettys,
+ so that no text gettys were available anymore.
+
+ * udev will now automatically inform the btrfs kernel logic
+ about btrfs RAID components showing up. This should make
+ simple hotplug based btrfs RAID assembly work.
+
+ * PID 1 will now increase its RLIMIT_NOFILE to 64K by default
+ (but not for its children which will stay at the kernel
+ default). This should allow setups with a lot more listening
+ sockets.
+
+ * systemd will now always pass the configured timezone to the
+ kernel at boot. timedated will do the same when the timezone
+ is changed.
+
+ * logind's inhibition logic has been updated. By default,
+ logind will now handle the lid switch, the power and sleep
+ keys all the time, even in graphical sessions. If DEs want
+ to handle these events on their own they should take the new
+ handle-power-key, handle-sleep-key and handle-lid-switch
+ inhibitors during their runtime. A simple way to achiveve
+ that is to invoke the DE wrapped in an invocation of:
+
+ systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ...
+
+ * Access to unit operations is now checked via SELinux taking
+ the unit file label and client process label into account.
+
+ * systemd will now notify the administrator in the journal
+ when he over-mounts a non-empty directory.
+
+ * There are new specifiers that are resolved in unit files,
+ for the host name (%H), the machine ID (%m) and the boot ID
+ (%b).

+
+CHANGES WITH 189:
+
+ * Support for reading structured kernel messages from
+ /dev/kmsg has now been added and is enabled by default.
+
+ * Support for reading kernel messages from /proc/kmsg has now
+ been removed. If you want kernel messages in the journal
+ make sure to run a recent kernel (>= 3.5) that supports
+ reading structured messages from /dev/kmsg (see
+ above). /proc/kmsg is now exclusive property of classic
+ syslog daemons again.
+
+ * The libudev API gained the new
+ udev_device_new_from_device_id() call.
+
+ * The logic for file system namespace (ReadOnlyDirectory=,
+ ReadWriteDirectoy=, PrivateTmp=) has been reworked not to
+ require pivot_root() anymore. This means fewer temporary
+ directories are created below /tmp for this feature.
+
+ * nspawn containers will now see and receive all submounts
+ made on the host OS below the root file system of the
+ container.
+
+ * Forward Secure Sealing is now supported for Journal files,
+ which provide cryptographical sealing of journal files so
+ that attackers cannot alter log history anymore without this
+ being detectable. Lennart will soon post a blog story about
+ this explaining it in more detail.
+
+ * There are two new service settings RestartPreventExitStatus=
+ and SuccessExitStatus= which allow configuration of exit
+ status (exit code or signal) which will be excepted from the
+ restart logic, resp. consider successful.
+
+ * journalctl gained the new --verify switch that can be used
+ to check the integrity of the structure of journal files and
+ (if Forward Secure Sealing is enabled) the contents of
+ journal files.
+
+ * nspawn containers will now be run with /dev/stdin, /dev/fd/
+ and similar symlinks pre-created. This makes running shells
+ as container init process a lot more fun.
+
+ * The fstab support can now handle PARTUUID= and PARTLABEL=
+ entries.
+
+ * A new ConditionHost= condition has been added to match
+ against the hostname (with globs) and machine ID. This is
+ useful for clusters where a single OS image is used to
+ provision a large number of hosts which shall run slightly
+ different sets of services.
+
+ * Services which hit the restart limit will now be placed in a
+ failure state.

+
+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.
