systemd System and Service Manager
-CHANGES WITH 219:
+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.
- (This changes list is very incomplete, and the release is
- weeks out still.)
+ * 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, ...)
