systemd System and Service Manager
+CHANGES WITH 226:
+
+ * The DHCP implementation of systemd-networkd gained a set of
+ new features:
+
+ - The DHCP server now supports emitting DNS and NTP
+ information. It may be enabled and configured via
+ EmitDNS=, DNS=, EmitNTP=, and NTP=. If transmission of DNS
+ and NTP information is enabled, but no servers are
+ configured, the corresponding uplink information (if there
+ is any) is propagated.
+
+ - Server and client now support transmission and reception
+ of timezone information. It can be configured via the
+ newly introduced network options UseTimezone=,
+ EmitTimezone=, and Timezone=. Transmission of timezone
+ information is enabled between host and containers by
+ default now: the container will change its local timezone
+ to what the host has set.
+
+ - Lease timeouts can now be configured via
+ MaxLeaseTimeSec= and DefaultLeaseTimeSec=.
+
+ - The DHCP server improved on the stability of
+ leases. Clients are more likely to get the same lease
+ information back, even if the server loses state.
+
+ - The DHCP server supports two new configuration options to
+ control the lease address pool metrics, PoolOffset= and
+ PoolSize=.
+
+ * The encapsulation limit of tunnels in systemd-networkd may
+ now be configured via 'EncapsulationLimit='. It allows
+ modifying the maximum additional levels of encapsulation
+ that are permitted to be prepended to a packet.
+
+ * systemd now supports the concept of user buses replacing
+ session buses, if used with dbus-1.10 (and enabled via dbus
+ --enable-user-session). It previously only supported this on
+ kdbus-enabled systems, and this release expands this to
+ 'dbus-daemon' systems.
+
+ * systemd-networkd now supports predictable interface names
+ for virtio devices.
+
+ * systemd now optionally supports the new Linux kernel
+ "unified" control group hierarchy. If enabled via the kernel
+ command-line option 'systemd.unified_cgroup_hierarchy=1',
+ systemd will try to mount the unified cgroup hierarchy
+ directly on /sys/fs/cgroup. If not enabled, or not
+ available, systemd will fall back to the legacy cgroup
+ hierarchy setup, as before. Host system and containers can
+ mix and match legacy and unified hierarchies as they
+ wish. nspawn understands the $UNIFIED_CROUP_HIERARCHY
+ environment variable to individually select the hierarchy to
+ use for executed containers. By default, nspawn will use the
+ unified hierarchy for the containers if the host uses the
+ unified hierarchy, and the legacy hierarchy otherwise.
+ Please note that at this point the unified hierarchy is an
+ experimental kernel feature and is likely to change in one
+ of the next kernel releases. Therefore, it should not be
+ enabled by default in downstream distributions yet. The
+ minimum required kernel version for the unified hierarchy to
+ work is 4.2. Note that when the unified hierarchy is used
+ for the first time delegated access to controllers is
+ safe. Because of this systemd-nspawn containers will get
+ access to controllers now, as will systemd user
+ sessions. This means containers and user sessions may now
+ manage their own resources, partitioning up what the system
+ grants them.
+
+ * A new special scope unit "init.scope" has been introduced
+ that encapsulates PID 1 of the system. It may be used to
+ determine resource usage and enforce resource limits on PID
+ 1 itself. PID 1 hence moved out of the root of the control
+ group tree.
+
+ * The cgtop tool gained support for filtering out kernel
+ threads when counting tasks in a control group. Also, the
+ count of processes is now recursively summed up by
+ default. Two options -k and --recursive= have been added to
+ revert to old behaviour. The tool has also been updated to
+ work correctly in containers now.
+
+ * systemd-nspawn's --bind= and --bind-ro= options have been
+ extended to allow creation of non-recursive bind mounts.
+
+ * libsystemd gained two new calls sd_pid_get_cgroup() and
+ sd_peer_get_cgroup() which return the control group path of
+ a process or peer of a connected AF_UNIX socket. This
+ function call is particularly useful when implementing
+ delegated subtrees support in the control group hierarchy.
+
+ * The "sd-event" event loop API of libsystemd now supports
+ correct dequeuing of real-time signals, without losing
+ signal events.
+
+ * When systemd requests a PolicyKit decision when managing
+ units it will now add additional fields to the request,
+ including unit name and desired operation. This enables more
+ powerful PolicyKit policies, that make decisions depending
+ on these parameters.
+
+ * nspawn learnt support for .nspawn settings files, that may
+ accompany the image files or directories of containers, and
+ may contain additional settings for the container. This is
+ an alternative to configuring container parameters via the
+ nspawn command line.

+
+CHANGES WITH 225:
+
+ * machinectl gained a new verb 'shell' which opens a fresh
+ shell on the target container or the host. It is similar to
+ the existing 'login' command of machinectl, but spawns the
+ shell directly without prompting for username or
+ password. The pseudo machine '.host' now refers to the local
+ host and is used by default. Hence, 'machinectl shell' can
+ be used as replacement for 'su -' which spawns a session as
+ a fresh systemd unit in a way that is fully isolated from
+ the originating session.
+
+ * systemd-networkd learned to cope with private-zone DHCP
+ options and allows other programs to query the values.
+
+ * SELinux access control when enabling/disabling units is no
+ longer enforced with this release. The previous
+ implementation was incorrect, and a new corrected
+ implementation is not yet available. As unit file operations
+ are still protected via PolicyKit and D-Bus policy this is
+ not a security problem. Yet, distributions which care about
+ optimal SELinux support should probably not stabilize on
+ this release.
+
+ * sd-bus gained support for matches of type "arg0has=", that
+ test for membership of strings in string arrays sent in bus
+ messages.
+
+ * systemd-resolved now dumps the contents of its DNS and LLMNR
+ caches to the logs on reception of the SIGUSR1 signal. This
+ is useful to debug DNS behaviour.
+
+ * The coredumpctl tool gained a new --directory= option to
+ operate on journal files in a specific directory.
+
+ * "systemctl reboot" and related commands gained a new
+ "--message=" option which may be used to set a free-text
+ wall message when shutting down or rebooting the
+ system. This message is also logged, which is useful for
+ figuring out the reason for a reboot or shutdown a
+ posteriori.
+
+ * The "systemd-resolve-host" tool's -i switch now takes
+ network interface numbers as alternative to interface names.
+
+ * A new unit file setting for services has been introduced:
+ UtmpMode= allows configuration of how precisely systemd
+ handles utmp and wtmp entries for the service if this is
+ enabled. This allows writing services that appear similar to
+ user sessions in the output of the "w", "who", "last" and
+ "lastlog" tools.
+
+ * systemd-resolved will now locally synthesize DNS resource
+ records for the "localhost" and "gateway" domains as well as
+ the local hostname. This should ensure that clients querying
+ RRs via resolved will get similar results as those going via
+ NSS, if nss-myhostname is enabled.

+
+CHANGES WITH 224:
+
+ * The systemd-efi-boot-generator functionality was merged into
+ systemd-gpt-auto-generator.
+
+ * systemd-networkd now supports Group Policy for vxlan
+ devices. It can be enabled via the new boolean configuration
+ option called 'GroupPolicyExtension='.

+
+CHANGES WITH 223:
+
+ * The python-systemd code has been removed from the systemd repository.
+ A new repository has been created which accommodates the code from
+ now on, and we kindly ask distributions to create a separate package
+ for this: https://github.com/systemd/python-systemd
+
+ * The systemd daemon will now reload its main configuration
+ (/etc/systemd/system.conf) on daemon-reload.
+
+ * sd-dhcp now exposes vendor specific extensions via
+ sd_dhcp_lease_get_vendor_specific().
+
+ * systemd-networkd gained a number of new configuration options.
+
+ - A new boolean configuration option for TAP devices called
+ 'VNetHeader='. If set, the IFF_VNET_HDR flag is set for the
+ device, thus allowing to send and receive GSO packets.
+
+ - A new tunnel configuration option called 'CopyDSCP='.
+ If enabled, the DSCP field of ip6 tunnels is copied into the
+ decapsulated packet.
+
+ - A set of boolean bridge configuration options were added.
+ 'UseBPDU=', 'HairPin=', 'FastLeave=', 'AllowPortToBeRoot=',
+ and 'UnicastFlood=' are now parsed by networkd and applied to the
+ respective bridge link device via the respective IFLA_BRPORT_*
+ netlink attribute.
+
+ - A new string configuration option to override the hostname sent
+ to a DHCP server, called 'Hostname='. If set and 'SendHostname='
+ is true, networkd will use the configured hostname instead of the
+ system hostname when sending DHCP requests.
+
+ - A new tunnel configuration option called 'IPv6FlowLabel='. If set,
+ networkd will configure the IPv6 flow-label of the tunnel device
+ according to RFC2460.
+
+ - The 'macvtap' virtual network devices are now supported, similar to
+ the already supported 'macvlan' devices.
+
+ * systemd-resolved now implements RFC5452 to improve resilience against
+ cache poisoning. Additionally, source port randomization is enabled
+ by default to further protect against DNS spoofing attacks.
+
+ * nss-mymachines now supports translating UIDs and GIDs of running
+ containers with user-namespaces enabled. If a container 'foo'
+ translates a host uid 'UID' to the container uid 'TUID', then
+ nss-mymachines will also map uid 'UID' to/from username 'vu-foo-TUID'
+ (with 'foo' and 'TUID' replaced accordingly). Similarly, groups are
+ mapped as 'vg-foo-TGID'.

+
+CHANGES WITH 222:
+
+ * udev does not longer support the WAIT_FOR_SYSFS= key in udev rules.
+ There are no known issues with current sysfs, and udev does not need
+ or should be used to work around such bugs.
+
+ * udev does no longer enable USB HID power management. Several reports
+ indicate, that some devices cannot handle that setting.
+
+ * The udev accelerometer helper was removed. The functionality
+ is now fully included in iio-sensor-proxy. But this means,
+ older iio-sensor-proxy versions will no longer provide
+ accelerometer/orientation data with this systemd version.
+ Please upgrade iio-sensor-proxy to version 1.0.
+
+ * networkd gained a new configuration option IPv6PrivacyExtensions=
+ which enables IPv6 privacy extensions (RFC 4941, "Privacy Extensions
+ for Stateless Address") on selected networks.
+
+ * For the sake of fewer build-time dependencies and less code in the
+ main repository, the python bindings are about to be removed in the
+ next release. A new repository has been created which accommodates
+ the code from now on, and we kindly ask distributions to create a
+ separate package for this. The removal will take place in v223.

+
+ -- Berlin, 2015-07-07
+
+CHANGES WITH 221:
+
+ * The sd-bus.h and sd-event.h APIs have now been declared
+ stable and have been added to the official interface of
+ libsystemd.so. sd-bus implements an alternative D-Bus client
+ library, that is relatively easy to use, very efficient and
+ supports both classic D-Bus as well as kdbus as transport
+ backend. sd-event is a generic event loop abstraction that
+ is built around Linux epoll, but adds features such as event
+ prioritization or efficient timer handling. Both APIs are good
+ choices for C programs looking for a bus and/or event loop
+ implementation that is minimal and does not have to be
+ portable to other kernels.
+
+ * kdbus support is no longer compile-time optional. It is now
+ always built-in. However, it can still be disabled at
+ runtime using the kdbus=0 kernel command line setting, and
+ that setting may be changed to default to off, by specifying
+ --disable-kdbus at build-time. Note though that the kernel
+ command line setting has no effect if the kdbus.ko kernel
+ module is not installed, in which case kdbus is (obviously)
+ also disabled. We encourage all downstream distributions to
+ begin testing kdbus by adding it to the kernel images in the
+ development distributions, and leaving kdbus support in
+ systemd enabled.
+
+ * The minimal required util-linux version has been bumped to
+ 2.26.
+
+ * Support for chkconfig (--enable-chkconfig) was removed in
+ favor of calling an abstraction tool
+ /lib/systemd/systemd-sysv-install. This needs to be
+ implemented for your distribution. See "SYSV INIT.D SCRIPTS"
+ in README for details.
+
+ * If there's a systemd unit and a SysV init script for the
+ same service name, and the user executes "systemctl enable"
+ for it (or a related call), then this will now enable both
+ (or execute the related operation on both), not just the
+ unit.
+
+ * The libudev API documentation has been converted from gtkdoc
+ into man pages.
+
+ * gudev has been removed from the systemd tree, it is now an
+ external project.
+
+ * The systemd-cgtop tool learnt a new --raw switch to generate
+ "raw" (machine parsable) output.
+
+ * networkd's IPForwarding= .network file setting learnt the
+ new setting "kernel", which ensures that networkd does not
+ change the IP forwarding sysctl from the default kernel
+ state.
+
+ * The systemd-logind bus API now exposes a new boolean
+ property "Docked" that reports whether logind considers the
+ system "docked", i.e. connected to a docking station or not.

+
+CHANGES WITH 220:
+
+ * The gudev library has been extracted into a separate repository
+ available at: https://git.gnome.org/browse/libgudev/
+ It is now managed as part of the Gnome project. Distributions
+ are recommended to pass --disable-gudev to systemd and use
+ gudev from the Gnome project instead. gudev is still included
+ in systemd, for now. It will be removed soon, though. Please
+ also see the announcement-thread on systemd-devel:
+ http://lists.freedesktop.org/archives/systemd-devel/2015-May/032070.html
+
+ * systemd now exposes a CPUUsageNSec= property for each
+ service unit on the bus, that contains the overall consumed
+ CPU time of a service (the sum of what each process of the
+ service consumed). This value is only available if
+ CPUAccounting= is turned on for a service, and is then shown
+ in the "systemctl status" output.
+
+ * Support for configuring alternative mappings of the old SysV
+ runlevels to systemd targets has been removed. They are now
+ hardcoded in a way that runlevels 2, 3, 4 all map to
+ multi-user.target and 5 to graphical.target (which
+ previously was already the default behaviour).
+
+ * The auto-mounter logic gained support for mount point
+ expiry, using a new TimeoutIdleSec= setting in .automount
+ units. (Also available as x-systemd.idle-timeout= in /etc/fstab).
+
+ * The EFI System Partition (ESP) as mounted to /boot by
+ systemd-efi-boot-generator will now be unmounted
+ automatically after 2 minutes of not being used. This should
+ minimize the risk of ESP corruptions.
+
+ * New /etc/fstab options x-systemd.requires= and
+ x-systemd.requires-mounts-for= are now supported to express
+ additional dependencies for mounts. This is useful for
+ journalling file systems that support external journal
+ devices or overlay file systems that require underlying file
+ systems to be mounted.
+
+ * systemd does not support direct live-upgrades (via systemctl
+ daemon-reexec) from versions older than v44 anymore. As no
+ distribution we are aware of shipped such old versions in a
+ stable release this should not be problematic.
+
+ * When systemd forks off a new per-connection service instance
+ it will now set the $REMOTE_ADDR environment variable to the
+ remote IP address, and $REMOTE_PORT environment variable to
+ the remote IP port. This behaviour is similar to the
+ corresponding environment variables defined by CGI.
+
+ * systemd-networkd gained support for uplink failure
+ detection. The BindCarrier= option allows binding interface
+ configuration dynamically to the link sense of other
+ interfaces. This is useful to achieve behaviour like in
+ network switches.
+
+ * systemd-networkd gained support for configuring the DHCP
+ client identifier to use when requesting leases.
+
+ * systemd-networkd now has a per-network UseNTP= option to
+ configure whether NTP server information acquired via DHCP
+ is passed on to services like systemd-timesyncd.
+
+ * systemd-networkd gained support for vti6 tunnels.
+
+ * Note that systemd-networkd manages the sysctl variable
+ /proc/sys/net/ipv[46]/conf/*/forwarding for each interface
+ it is configured for since v219. The variable controls IP
+ forwarding, and is a per-interface alternative to the global
+ /proc/sys/net/ipv[46]/ip_forward. This setting is
+ configurable in the IPForward= option, which defaults to
+ "no". This means if networkd is used for an interface it is
+ no longer sufficient to set the global sysctl option to turn
+ on IP forwarding! Instead, the .network file option
+ IPForward= needs to be turned on! Note that the
+ implementation of this behaviour was broken in v219 and has
+ been fixed in v220.
+
+ * Many bonding and vxlan options are now configurable in
+ systemd-networkd.
+
+ * systemd-nspawn gained a new --property= setting to set unit
+ properties for the container scope. This is useful for
+ setting resource parameters (e.g "CPUShares=500") on
+ containers started from the command line.
+
+ * systemd-nspawn gained a new --private-users= switch to make
+ use of user namespacing available on recent Linux kernels.
+
+ * systemd-nspawn may now be called as part of a shell pipeline
+ in which case the pipes used for stdin and stdout are passed
+ directly to the process invoked in the container, without
+ indirection via a pseudo tty.
+
+ * systemd-nspawn gained a new switch to control the UNIX
+ signal to use when killing the init process of the container
+ when shutting down.
+
+ * systemd-nspawn gained a new --overlay= switch for mounting
+ overlay file systems into the container using the new kernel
+ overlayfs support.
+
+ * When a container image is imported via systemd-importd and
+ the host file system is not btrfs, a loopback block device
+ file is created in /var/lib/machines.raw with a btrfs file
+ system inside. It is then mounted to /var/lib/machines to
+ enable btrfs features for container management. The loopback
+ file and btrfs file system is grown as needed when container
+ images are imported via systemd-importd.
+
+ * systemd-machined/systemd-importd gained support for btrfs
+ quota, to enforce container disk space limits on disk. This
+ is exposed in "machinectl set-limit".
+
+ * systemd-importd now can import containers from local .tar,
+ .raw and .qcow2 images, and export them to .tar and .raw. It
+ can also import dkr v2 images now from the network (on top
+ of v1 as before).
+
+ * systemd-importd gained support for verifying downloaded
+ images with gpg2 (previously only gpg1 was supported).
+
+ * systemd-machined, systemd-logind, systemd: most bus calls
+ are now accessible to unprivileged processes via
+ PolicyKit. Also, systemd-logind will now allow users to kill
+ their own sessions without further privileges or
+ authorization.
+
+ * systemd-shutdownd has been removed. This service was
+ previously responsible for implementing scheduled shutdowns
+ as exposed in /usr/bin/shutdown's time parameter. This
+ functionality has now been moved into systemd-logind and is
+ accessible via a bus interface.
+
+ * "systemctl reboot" gained a new switch --firmware-setup that
+ can be used to reboot into the EFI firmware setup, if that
+ is available. systemd-logind now exposes an API on the bus
+ to trigger such reboots, in case graphical desktop UIs want
+ to cover this functionality.
+
+ * "systemctl enable", "systemctl disable" and "systemctl mask"
+ now support a new "--now" switch. If specified the units
+ that are enabled will also be started, and the ones
+ disabled/masked also stopped.
+
+ * The Gummiboot EFI boot loader tool has been merged into
+ systemd, and renamed to "systemd-boot". The bootctl tool has been
+ updated to support systemd-boot.
+
+ * An EFI kernel stub has been added that may be used to create
+ kernel EFI binaries that contain not only the actual kernel,
+ but also an initrd, boot splash, command line and OS release
+ information. This combined binary can then be signed as a
+ single image, so that the firmware can verify it all in one
+ step. systemd-boot has special support for EFI binaries created
+ like this and can extract OS release information from them
+ and show them in the boot menu. This functionality is useful
+ to implement cryptographically verified boot schemes.
+
+ * Optional support has been added to systemd-fsck to pass
+ fsck's progress report to an AF_UNIX socket in the file
+ system.
+
+ * udev will no longer create device symlinks for all block
+ devices by default. A blacklist for excluding special block
+ devices from this logic has been turned into a whitelist
+ that requires picking block devices explicitly that require
+ device symlinks.
+
+ * A new (currently still internal) API sd-device.h has been
+ added to libsystemd. This modernized API is supposed to
+ replace libudev eventually. In fact, already much of libudev
+ is now just a wrapper around sd-device.h.
+
+ * A new hwdb database for storing metadata about pointing
+ stick devices has been added.
+
+ * systemd-tmpfiles gained support for setting file attributes
+ similar to the "chattr" tool with new 'h' and 'H' lines.
+
+ * systemd-journald will no longer unconditionally set the
+ btrfs NOCOW flag on new journal files. This is instead done
+ with tmpfiles snippet using the new 'h' line type. This
+ allows easy disabling of this logic, by masking the
+ journal-nocow.conf tmpfiles file.
+
+ * systemd-journald will now translate audit message types to
+ human readable identifiers when writing them to the
+ journal. This should improve readability of audit messages.
+
+ * The LUKS logic gained support for the offset= and skip=
+ options in /etc/crypttab, as previously implemented by
+ Debian.
+
+ * /usr/lib/os-release gained a new optional field VARIANT= for
+ distributions that support multiple variants (such as a
+ desktop edition, a server edition, ...)

+CHANGES WITH 219:
+
+ * Introduce a new API "sd-hwdb.h" for querying the hardware
+ metadata database. With this minimal interface one can query
+ and enumerate the udev hwdb, decoupled from the old libudev
+ library. libudev's interface for this is now only a wrapper
+ around sd-hwdb. A new tool systemd-hwdb has been added to
+ interface with and update the database.
+
+ * When any of systemd's tools copies files (for example due to
+ tmpfiles' C lines) a btrfs reflink will attempted first,
+ before bytewise copying is done.
+
+ * systemd-nspawn gained a new --ephemeral switch. When
+ specified a btrfs snapshot is taken of the container's root
+ directory, and immediately removed when the container
+ terminates again. Thus, a container can be started whose
+ changes never alter the container's root directory, and are
+ lost on container termination. This switch can also be used
+ for starting a container off the root file system of the
+ host without affecting the host OS. This switch is only
+ available on btrfs file systems.
+
+ * systemd-nspawn gained a new --template= switch. It takes the
+ path to a container tree to use as template for the tree
+ specified via --directory=, should that directory be
+ missing. This allows instantiating containers dynamically,
+ on first run. This switch is only available on btrfs file
+ systems.
+
+ * When a .mount unit refers to a mount point on which multiple
+ mounts are stacked, and the .mount unit is stopped all of
+ the stacked mount points will now be unmounted until no
+ mount point remains.
+
+ * systemd now has an explicit notion of supported and
+ unsupported unit types. Jobs enqueued for unsupported unit
+ types will now fail with an "unsupported" error code. More
+ specifically .swap, .automount and .device units are not
+ supported in containers, .busname units are not supported on
+ non-kdbus systems. .swap and .automount are also not
+ supported if their respective kernel compile time options
+ are disabled.
+
+ * machinectl gained support for two new "copy-from" and
+ "copy-to" commands for copying files from a running
+ container to the host or vice versa.
+
+ * machinectl gained support for a new "bind" command to bind
+ mount host directories into local containers. This is
+ currently only supported for nspawn containers.
+
+ * networkd gained support for configuring bridge forwarding
+ database entries (fdb) from .network files.
+
+ * A new tiny daemon "systemd-importd" has been added that can
+ download container images in tar, raw, qcow2 or dkr formats,
+ and make them available locally in /var/lib/machines, so
+ that they can run as nspawn containers. The daemon can GPG
+ verify the downloads (not supported for dkr, since it has no
+ provisions for verifying downloads). It will transparently
+ decompress bz2, xz, gzip compressed downloads if necessary,
+ and restore sparse files on disk. The daemon uses privilege
+ separation to ensure the actual download logic runs with
+ fewer privileges than the daemon itself. machinectl has
+ gained new commands "pull-tar", "pull-raw" and "pull-dkr" to
+ make the functionality of importd available to the
+ user. With this in place the Fedora and Ubuntu "Cloud"
+ images can be downloaded and booted as containers unmodified
+ (the Fedora images lack the appropriate GPG signature files
+ currently, so they cannot be verified, but this will change
+ soon, hopefully). Note that downloading images is currently
+ only fully supported on btrfs.
+
+ * machinectl is now able to list container images found in
+ /var/lib/machines, along with some metadata about sizes of
+ disk and similar. If the directory is located on btrfs and
+ quota is enabled, this includes quota display. A new command
+ "image-status" has been added that shows additional
+ information about images.
+
+ * machinectl is now able to clone container images
+ efficiently, if the underlying file system (btrfs) supports
+ it, with the new "machinectl list-images" command. It also
+ gained commands for renaming and removing images, as well as
+ marking them read-only or read-write (supported also on
+ legacy file systems).
+
+ * networkd gained support for collecting LLDP network
+ announcements, from hardware that supports this. This is
+ shown in networkctl output.
+
+ * systemd-run gained support for a new -t (--pty) switch for
+ invoking a binary on a pty whose input and output is
+ connected to the invoking terminal. This allows executing
+ processes as system services while interactively
+ communicating with them via the terminal. Most interestingly
+ this is supported across container boundaries. Invoking
+ "systemd-run -t /bin/bash" is an alternative to running a
+ full login session, the difference being that the former
+ will not register a session, nor go through the PAM session
+ setup.
+
+ * tmpfiles gained support for a new "v" line type for creating
+ btrfs subvolumes. If the underlying file system is a legacy
+ file system, this automatically degrades to creating a
+ normal directory. Among others /var/lib/machines is now
+ created like this at boot, should it be missing.
+
+ * The directory /var/lib/containers/ has been deprecated and
+ been replaced by /var/lib/machines. The term "machines" has
+ been used in the systemd context as generic term for both
+ VMs and containers, and hence appears more appropriate for
+ this, as the directory can also contain raw images bootable
+ via qemu/kvm.
+
+ * systemd-nspawn when invoked with -M but without --directory=
+ or --image= is now capable of searching for the container
+ root directory, subvolume or disk image automatically, in
+ /var/lib/machines. systemd-nspawn@.service has been updated
+ to make use of this, thus allowing it to be used for raw
+ disk images, too.
+
+ * A new machines.target unit has been introduced that is
+ supposed to group all containers/VMs invoked as services on
+ the system. systemd-nspawn@.service has been updated to
+ integrate with that.
+
+ * machinectl gained a new "start" command, for invoking a
+ container as a service. "machinectl start foo" is mostly
+ equivalent to "systemctl start systemd-nspawn@foo.service",
+ but handles escaping in a nicer way.
+
+ * systemd-nspawn will now mount most of the cgroupfs tree
+ read-only into each container, with the exception of the
+ container's own subtree in the name=systemd hierarchy.
+
+ * journald now sets the special FS_NOCOW file flag for its
+ journal files. This should improve performance on btrfs, by
+ avoiding heavy fragmentation when journald's write-pattern
+ is used on COW file systems. It degrades btrfs' data
+ integrity guarantees for the files to the same levels as for
+ ext3/ext4 however. This should be OK though as journald does
+ its own data integrity checks and all its objects are
+ checksummed on disk. Also, journald should handle btrfs disk
+ full events a lot more gracefully now, by processing SIGBUS
+ errors, and not relying on fallocate() anymore.
+
+ * When journald detects that journal files it is writing to
+ have been deleted it will immediately start new journal
+ files.
+
+ * systemd now provides a way to store file descriptors
+ per-service in PID 1.This is useful for daemons to ensure
+ that fds they require are not lost during a daemon
+ restart. The fds are passed to the daemon on the next
+ invocation in the same way socket activation fds are
+ passed. This is now used by journald to ensure that the
+ various sockets connected to all the system's stdout/stderr
+ are not lost when journald is restarted. File descriptors
+ may be stored in PID 1 via the sd_pid_notify_with_fds() API,
+ an extension to sd_notify(). Note that a limit is enforced
+ on the number of fds a service can store in PID 1, and it
+ defaults to 0, so that no fds may be stored, unless this is
+ explicitly turned on.
+
+ * The default TERM variable to use for units connected to a
+ terminal, when no other value is explicitly is set is now
+ vt220 rather than vt102. This should be fairly safe still,
+ but allows PgUp/PgDn work.
+
+ * The /etc/crypttab option header= as known from Debian is now
+ supported.
+
+ * "loginctl user-status" and "loginctl session-status" will
+ now show the last 10 lines of log messages of the
+ user/session following the status output. Similar,
+ "machinectl status" will show the last 10 log lines
+ associated with a virtual machine or container
+ service. (Note that this is usually not the log messages
+ done in the VM/container itself, but simply what the
+ container manager logs. For nspawn this includes all console
+ output however.)
+
+ * "loginctl session-status" without further argument will now
+ show the status of the session of the caller. Similar,
+ "lock-session", "unlock-session", "activate",
+ "enable-linger", "disable-linger" may now be called without
+ session/user parameter in which case they apply to the
+ caller's session/user.
+
+ * An X11 session scriptlet is now shipped that uploads
+ $DISPLAY and $XAUTHORITY into the environment of the systemd
+ --user daemon if a session begins. This should improve
+ compatibility with X11 enabled applications run as systemd
+ user services.
+
+ * Generators are now subject to masking via /etc and /run, the
+ same way as unit files.
+
+ * networkd .network files gained support for configuring
+ per-link IPv4/IPv6 packet forwarding as well as IPv4
+ masquerading. This is by default turned on for veth links to
+ containers, as registered by systemd-nspawn. This means that
+ nspawn containers run with --network-veth will now get
+ automatic routed access to the host's networks without any
+ further configuration or setup, as long as networkd runs on
+ the host.
+
+ * systemd-nspawn gained the --port= (-p) switch to expose TCP
+ or UDP posts of a container on the host. With this in place
+ it is possible to run containers with private veth links
+ (--network-veth), and have their functionality exposed on
+ the host as if their services were running directly on the
+ host.
+
+ * systemd-nspawn's --network-veth switch now gained a short
+ version "-n", since with the changes above it is now truly
+ useful out-of-the-box. The systemd-nspawn@.service has been
+ updated to make use of it too by default.
+
+ * systemd-nspawn will now maintain a per-image R/W lock, to
+ ensure that the same image is not started more than once
+ writable. (It's OK to run an image multiple times
+ simultaneously in read-only mode.)
+
+ * systemd-nspawn's --image= option is now capable of
+ dissecting and booting MBR and GPT disk images that contain
+ only a single active Linux partition. Previously it
+ supported only GPT disk images with proper GPT type
+ IDs. This allows running cloud images from major
+ distributions directly with systemd-nspawn, without
+ modification.
+
+ * In addition to collecting mouse dpi data in the udev
+ hardware database, there's now support for collecting angle
+ information for mouse scroll wheels. The database is
+ supposed to guarantee similar scrolling behavior on mice
+ that it knows about. There's also support for collecting
+ information about Touchpad types.
+
+ * udev's input_id built-in will now also collect touch screen
+ dimension data and attach it to probed devices.
+
+ * /etc/os-release gained support for a Distribution Privacy
+ Policy link field.
+
+ * networkd gained support for creating "ipvlan", "gretap",
+ "ip6gre", "ip6gretap" and "ip6tnl" network devices.
+
+ * systemd-tmpfiles gained support for "a" lines for setting
+ ACLs on files.
+
+ * systemd-nspawn will now mount /tmp in the container to
+ tmpfs, automatically.
+
+ * systemd now exposes the memory.usage_in_bytes cgroup
+ attribute and shows it for each service in the "systemctl
+ status" output, if available.
+
+ * When the user presses Ctrl-Alt-Del more than 7x within 2s an
+ immediate reboot is triggered. This useful if shutdown is
+ hung and is unable to complete, to expedite the
+ operation. Note that this kind of reboot will still unmount
+ all file systems, and hence should not result in fsck being
+ run on next reboot.
+
+ * A .device unit for an optical block device will now be
+ considered active only when a medium is in the drive. Also,
+ mount units are now bound to their backing devices thus
+ triggering automatic unmounting when devices become
+ unavailable. With this in place systemd will now
+ automatically unmount left-over mounts when a CD-ROM is
+ ejected or an USB stick is yanked from the system.
+
+ * networkd-wait-online now has support for waiting for
+ specific interfaces only (with globbing), and for giving up
+ after a configurable timeout.
+
+ * networkd now exits when idle. It will be automatically
+ restarted as soon as interfaces show up, are removed or
+ change state. networkd will stay around as long as there is
+ at least one DHCP state machine or similar around, that keep
+ it non-idle.
+
+ * networkd may now configure IPv6 link-local addressing in
+ addition to IPv4 link-local addressing.
+
+ * The IPv6 "token" for use in SLAAC may now be configured for
+ each .network interface in networkd.
+
+ * Routes configured with networkd may now be assigned a scope
+ in .network files.
+
+ * networkd's [Match] sections now support globbing and lists
+ of multiple space-separated matches per item.

+
+CHANGES WITH 218:
+
+ * When querying unit file enablement status (for example via
+ "systemctl is-enabled"), a new state "indirect" is now known
+ which indicates that a unit might not be enabled itself, but
+ another unit listed in its Also= setting might be.
+
+ * Similar to the various existing ConditionXYZ= settings for
+ units there are now matching AssertXYZ= settings. While
+ failing conditions cause a unit to be skipped, but its job
+ to succeed, failing assertions declared like this will cause
+ a unit start operation and its job to fail.
+
+ * hostnamed now knows a new chassis type "embedded".
+
+ * systemctl gained a new "edit" command. When used on a unit
+ file this allows extending unit files with .d/ drop-in
+ configuration snippets or editing the full file (after
+ copying it from /usr/lib to /etc). This will invoke the
+ user's editor (as configured with $EDITOR), and reload the
+ modified configuration after editing.
+
+ * "systemctl status" now shows the suggested enablement state
+ for a unit, as declared in the (usually vendor-supplied)
+ system preset files.
+
+ * nss-myhostname will now resolve the single-label host name
+ "gateway" to the locally configured default IP routing
+ gateways, ordered by their metrics. This assigns a stable
+ name to the used gateways, regardless which ones are
+ currently configured. Note that the name will only be
+ resolved after all other name sources (if nss-myhostname is
+ configured properly) and should hence not negatively impact
+ systems that use the single-label host name "gateway" in
+ other contexts.
+
+ * systemd-inhibit now allows filtering by mode when listing
+ inhibitors.
+
+ * Scope and service units gained a new "Delegate" boolean
+ property, which when set allows processes running inside the
+ unit to further partition resources. This is primarily
+ useful for systemd user instances as well as container
+ managers.
+
+ * journald will now pick up audit messages directly from
+ the kernel, and log them like any other log message. The
+ audit fields are split up and fully indexed. This means that
+ journalctl in many ways is now a (nicer!) alternative to
+ ausearch, the traditional audit client. Note that this
+ implements only a minimal audit client, if you want the
+ special audit modes like reboot-on-log-overflow, please use
+ the traditional auditd instead, which can be used in
+ parallel to journald.
+
+ * The ConditionSecurity= unit file option now understands the
+ special string "audit" to check whether auditing is
+ available.
+
+ * journalctl gained two new commands --vacuum-size= and
+ --vacuum-time= to delete old journal files until the
+ remaining ones take up no more the specified size on disk,
+ or are not older than the specified time.
+
+ * A new, native PPPoE library has been added to sd-network,
+ systemd's library of light-weight networking protocols. This
+ library will be used in a future version of networkd to
+ enable PPPoE communication without an external pppd daemon.
+
+ * The busctl tool now understands a new "capture" verb that
+ works similar to "monitor", but writes a packet capture
+ trace to STDOUT that can be redirected to a file which is
+ compatible with libcap's capture file format. This can then
+ be loaded in Wireshark and similar tools to inspect bus
+ communication.
+
+ * The busctl tool now understands a new "tree" verb that shows
+ the object trees of a specific service on the bus, or of all
+ services.
+
+ * The busctl tool now understands a new "introspect" verb that
+ shows all interfaces and members of objects on the bus,
+ including their signature and values. This is particularly
+ useful to get more information about bus objects shown by
+ the new "busctl tree" command.
+
+ * The busctl tool now understands new verbs "call",
+ "set-property" and "get-property" for invoking bus method
+ calls, setting and getting bus object properties in a
+ friendly way.
+
+ * busctl gained a new --augment-creds= argument that controls
+ whether the tool shall augment credential information it
+ gets from the bus with data from /proc, in a possibly
+ race-ful way.
+
+ * nspawn's --link-journal= switch gained two new values
+ "try-guest" and "try-host" that work like "guest" and
+ "host", but do not fail if the host has no persistent
+ journalling enabled. -j is now equivalent to
+ --link-journal=try-guest.
+
+ * macvlan network devices created by nspawn will now have
+ stable MAC addresses.
+
+ * A new SmackProcessLabel= unit setting has been added, which
+ controls the SMACK security label processes forked off by
+ the respective unit shall use.
+
+ * If compiled with --enable-xkbcommon, systemd-localed will
+ verify x11 keymap settings by compiling the given keymap. It
+ will spew out warnings if the compilation fails. This
+ requires libxkbcommon to be installed.
+
+ * When a coredump is collected a larger number of metadata
+ fields is now collected and included in the journal records
+ created for it. More specifically control group membership,
+ environment variables, memory maps, working directory,
+ chroot directory, /proc/$PID/status, and a list of open file
+ descriptors is now stored in the log entry.
+
+ * The udev hwdb now contains DPI information for mice. For
+ details see:
+
+ http://who-t.blogspot.de/2014/12/building-a-dpi-database-for-mice.html
+
+ * All systemd programs that read standalone configuration
+ files in /etc now also support a corresponding series of
+ .conf.d configuration directories in /etc/, /run/,
+ /usr/local/lib/, /usr/lib/, and (if configured with
+ --enable-split-usr) /lib/. In particular, the following
+ configuration files now have corresponding configuration
+ directories: system.conf user.conf, logind.conf,
+ journald.conf, sleep.conf, bootchart.conf, coredump.conf,
+ resolved.conf, timesyncd.conf, journal-remote.conf, and
+ journal-upload.conf. Note that distributions should use the
+ configuration directories in /usr/lib/; the directories in
+ /etc/ are reserved for the system administrator.
+
+ * systemd-rfkill will no longer take the rfkill device name
+ into account when storing rfkill state on disk, as the name
+ might be dynamically assigned and not stable. Instead, the
+ ID_PATH udev variable combined with the rfkill type (wlan,
+ bluetooth, ...) is used.
+
+ * A new service systemd-machine-id-commit.service has been
+ added. When used on systems where /etc is read-only during
+ boot, and /etc/machine-id is not initialized (but an empty
+ file), this service will copy the temporary machine ID
+ created as replacement into /etc after the system is fully
+ booted up. This is useful for systems that are freshly
+ installed with a non-initialized machine ID, but should get
+ a fixed machine ID for subsequent boots.
+
+ * networkd's .netdev files now provide a large set of
+ configuration parameters for VXLAN devices. Similar, the
+ bridge port cost parameter is now configurable in .network
+ files. There's also new support for configuring IP source
+ routing. networkd .link files gained support for a new
+ OriginalName= match that is useful to match against the
+ original interface name the kernel assigned. .network files
+ may include MTU= and MACAddress= fields for altering the MTU
+ and MAC address while being connected to a specific network
+ interface.
+
+ * The LUKS logic gained supported for configuring
+ UUID-specific key files. There's also new support for naming
+ LUKS device from the kernel command line, using the new
+ luks.name= argument.
+
+ * Timer units may now be transiently created via the bus API
+ (this was previously already available for scope and service
+ units). In addition it is now possible to create multiple
+ transient units at the same time with a single bus call. The
+ "systemd-run" tool has been updated to make use of this for
+ running commands on a specified time, in at(1)-style.
+
+ * tmpfiles gained support for "t" lines, for assigning
+ extended attributes to files. Among other uses this may be
+ used to assign SMACK labels to files.
