-CHANGES WITH 237 in spe:
+CHANGES WITH 239 in spe:
+
+ * NETWORK INTERFACE DEVICE NAMING CHANGES: systemd-udevd's "net_id"
+ builtin will name network interfaces differently than in previous
+ versions for virtual network interfaces created with SR-IOV and NPAR
+ and for devices where the PCI network controller device does not have
+ a slot number associated.
+
+ SR-IOV virtual devices are now named based on the name of the parent
+ interface, with a suffix of "v<N>", where <N> is the virtual device
+ number. Previously those virtual devices were named as if completely
+ independent.
+
+ The ninth and later NPAR virtual devices will be named following the
+ scheme used for the first eight NPAR partitions. Previously those
+ devices were not renamed and the kernel default (eth<n>) was used.
+
+ "net_id" will also generate names for PCI devices where the PCI
+ network controller device does not have an associated slot number
+ itself, but one of its parents does. Previously those devices were
+ not renamed and the kernel default (eth<n>) was used.
+
+ * AF_INET and AF_INET6 are dropped from RestrictAddressFamilies= in
+ systemd-logind.service. Since v235, IPAddressDeny=any has been set to
+ the unit. So, it is expected that the default behavior of
+ systemd-logind is not changed. However, if distribution packagers or
+ administrators disabled or modified IPAddressDeny= setting by a
+ drop-in config file, then it may be necessary to update the file to
+ re-enable AF_INET and AF_INET6 to support network user name services,
+ e.g. NIS.
+
+ * When the RestrictNamespaces= unit property is specified multiple
+ times, then the specified types are merged now. Previously, only the
+ last assignment was used. So, if distribution packagers or
+ administrators modified the setting by a drop-in config file, then it
+ may be necessary to update the file.
+
+ * When OnFailure= is used in combination with Restart= on a service
+ unit, then the specified units will no longer be triggered on
+ failures that result in restarting. Previously, the specified units
+ would be activated each time the unit failed, even when the unit was
+ going to be restarted automatically. This behaviour contradicted the
+ documentation. With this release the code is adjusted to match the
+ documentation.
+
+ * systemd-tmpfiles will now print a notice whenever it encounters
+ tmpfiles.d/ lines referencing the /var/run/ directory. It will
+ recommend reworking them to use the /run/ directory instead (for
+ which /var/run/ is simply a symlinked compatibility alias). This way
+ systemd-tmpfiles can properly detect line conflicts and merge lines
+ referencing the same file by two paths, without having to access
+ them.
+
+ * systemctl disable/unmask/preset/preset-all cannot be used with
+ --runtime. Previously this was allowed, but resulted in unintuitive
+ behaviour that wasn't useful. systemctl disable/unmask will now undo
+ both runtime and persistent enablement/masking, i.e. it will remove
+ any relevant symlinks both in /run and /etc.
+
+ * Note that all long-running system services shipped with systemd will
+ now default to a system call whitelist (rather than a blacklist, as
+ before). In particular, systemd-udevd will now enforce one too. For
+ most cases this should be safe, however downstream distributions
+ which disabled sandboxing of systemd-udevd (specifically the
+ MountFlags= setting), might want to disable this security feature
+ too, as the default whitelisting will prohibit all mount, swap,
+ reboot and clock changing operations from udev rules.
+
+ * sd-boot acquired new loader configuration settings to optionally turn
+ off Windows and MacOS boot partition discovery as well as
+ reboot-into-firmware menu items. It is also able to pick a better
+ screen resolution for HiDPI systems, and now provides loader
+ configuration settings to change the resolution explicitly.
+
+ * systemd-resolved now supports DNS-over-TLS. It's still
+ turned off by default, use DNSOverTLS=opportunistic to turn it on in
+ resolved.conf. We intend to make this the default as soon as couple
+ of additional techniques for optimizing the initial latency caused by
+ establishing a TLS/TCP connection are implemented.
+
+ * systemd-resolved.service and systemd-networkd.service now set
+ DynamicUser=yes. The users systemd-resolve and systemd-network are
+ not created by systemd-sysusers.
+
+ * The systemd-resolve tool has been renamed to resolvectl (it also
+ remains available under the old name, for compatibility), and its
+ interface is now verb-based, similar in style to the other <xyz>ctl
+ tools, such as systemctl or loginctl.
+
+ * The resolvectl/systemd-resolve tool also provides 'resolvconf'
+ compatibility. It may be symlinked under the 'resolvconf' name, in
+ which case it will take arguments and input compatible with the
+ Debian and FreeBSD resolvconf tool.
+
+ * Support for suspend-then-hibernate has been added, i.e. a sleep mode
+ where the system initially suspends, and after a time-out resumes and
+ hibernates again.
+
+ * networkd's ClientIdentifier= now accepts a new option "duid-only". If
+ set the client will only send a DUID as client identifier.
+
+ * The nss-systemd glibc NSS module will now enumerate dynamic users and
+ groups in effect. Previously, it could resolve UIDs/GIDs to user
+ names/groups and vice versa, but did not support enumeration.
+
+ * journald's Compress= configuration setting now optionally accepts a
+ byte threshold value. All journal objects larger than this threshold
+ will be compressed, smaller ones will not. Previously this threshold
+ was not configurable and set to 512.
+
+ * A new system.conf setting NoNewPrivileges= is now available which may
+ be used to turn off acquisition of new privileges system-wide
+ (i.e. set Linux' PR_SET_NO_NEW_PRIVS for PID 1 itself, and thus also
+ for all its children). Note that turning this option on means setuid
+ binaries and file system capabilities lose their special powers.
+ While turning on this option is a big step towards a more secure
+ system, doing so is likely to break numerous pre-existing UNIX tools,
+ in particular su and sudo.
+
+ * A new service systemd-time-sync-wait.service has been added. If
+ enabled it will delay the time-sync.target unit at boot until time
+ synchronization has been received from the network. This
+ functionality is useful on systems lacking a local RTC or where it is
+ acceptable that the boot process shall be delayed by external network
+ services.
+
+ * When hibernating, systemd will now inform the kernel of the image
+ write offset, on kernels new enough to support this. This means swap
+ files should work for hibernation now.
+
+ * When loading unit files, systemd will now look for drop-in unit files
+ extensions in additional places. Previously, for a unit file name
+ "foo-bar-baz.service" it would look for dropin files in
+ "foo-bar-baz.service.d/*.conf". Now, it will also look in
+ "foo-bar-.service.d/*.conf" and "foo-.service.d/", i.e. at the
+ service name truncated after all inner dashes. This scheme allows
+ writing drop-ins easily that apply to a whole set of unit files at
+ once. It's particularly useful for mount and slice units (as their
+ naming is prefix based), but is also useful for service and other
+ units, for packages that install multiple unit files at once,
+ following a strict naming regime of beginning the unit file name with
+ the package's name. Two new specifiers are now supported in unit
+ files to match this: %j and %J are replaced by the part of the unit
+ name following the last dash.
+
+ * Unit files and other configuration files that support specifier
+ expansion now understand another two new specifiers: %T and %V will
+ resolve to /tmp and /var/tmp respectively, or whatever temporary
+ directory has been set for the calling user.
+
+ * The ExecStart= lines of unit files are no longer required to
+ reference absolute paths. If non-absolute paths are specified the
+ specified binary name is searched within the service manager's
+ built-in $PATH, which may be queried with 'systemd-path
+ search-binaries-default'. It's generally recommended to continue to
+ use absolute paths for all binaries specified in unit files.
+
+ * Units gained a new load state "bad-setting", which is used when a
+ unit file was loaded, but contained fatal errors which prevent it
+ from being started (for example, a service unit has been defined
+ lacking both ExecStart= and ExecStop= lines).
+
+ * coredumpctl's "gdb" verb has been renamed to "debug", in order to
+ support alternative debuggers, for example lldb. The old name
+ continues to be available however, for compatibility reasons. Use the
+ new --debugger= switch or the $SYSTEMD_DEBUGGER environment variable
+ to pick an alternative debugger instead of the default gdb.
+
+ * systemctl and the other tools will now output escape sequences that
+ generate proper clickable hyperlinks in various terminal emulators
+ where useful (for example, in the "systemctl status" output you can
+ now click on the unit file name to quickly open it in the
+ editor/viewer of your choice). Note that not all terminal emulators
+ support this functionality yet, but many do. Unfortunately, the
+ "less" pager doesn't support this yet, hence this functionality is
+ currently automatically turned off when a pager is started (which
+ happens quite often due to auto-paging). We hope to remove this
+ limitation as soon as "less" learns these escape sequences. This new
+ behaviour may also be turned off explicitly with the $SYSTEMD_URLIFY
+ environment variable. For details on these escape sequences see:
+ https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda
+
+ * networkd's .network files now support a new IPv6MTUBytes= option for
+ setting the MTU used by IPv6 explicitly as well as a new MTUBytes=
+ option in the [Route] section to configure the MTU to use for
+ specific routes. It also gained support for configuration of the DHCP
+ "UserClass" option through the new UserClass= setting. It gained
+ three new options in the new [CAN] section for configuring CAN
+ networks. The MULTICAST and ALLMULTI interface flags may now be
+ controlled explicitly with the new Multicast= and AllMulticast=
+ settings.
+
+ * networkd will now automatically make use of the kernel's route
+ expiration feature, if it is available.
+
+ * udevd's .link files now support setting the number of receive and
+ transmit channels, using the RxChannels=, TxChannels=,
+ OtherChannels=, CombinedChannels= settings.
+
+ * Support for UDPSegmentationOffload= has been removed, given its
+ limited support in hardware, and waning software support.
+
+ * networkd's .netdev files now support creating "netdevsim" interfaces.
+
+ * PID 1 learnt a new bus call GetUnitByControlGroup() which may be used
+ to query the unit belonging to a specific kernel control group.
+
+ * systemd-analyze gained a new verb "cat-config", which may be used to
+ dump the contents of any configuration file, with all its matching
+ drop-in files added in, and honouring the usual search and masking
+ logic applied to systemd configuration files. For example use
+ "systemd-analyze cat-config systemd/system.conf" to get the complete
+ system configuration file of systemd how it would be loaded by PID 1
+ itself. Similar to this, various tools such as systemd-tmpfiles or
+ systemd-sysusers, gained a new option "--cat-config", which does the
+ corresponding operation for their own configuration settings. For
+ example, "systemd-tmpfiles --cat-config" will now output the full
+ list of tmpfiles.d/ lines in place.
+
+ * timedatectl gained two new verbs "timesync-status" (to show the
+ current NTP synchronization state of systemd-timesyncd) and
+ "show-timesync" (to show bus properties of systemd-timesyncd).
+
+ * systemd-timesyncd gained a bus interface on which it exposes details
+ about its state.
+
+ * A new environment variable $SYSTEMD_TIMEDATED_NTP_SERVICES is now
+ understood by systemd-timedated. It takes a colon-separated list of
+ unit names of NTP client services. The list is used by
+ "timedatectl set-ntp".
+
+ * systemd-nspawn gained a new --rlimit= switch for setting initial
+ resource limits for the container payload. There's a new switch
+ --hostname= to explicitly override the container's hostname. A new
+ --no-new-privileges= switch may be used to control the
+ PR_SET_NO_NEW_PRIVS flag for the container payload. A new
+ --oom-score-adjust= switch controls the OOM scoring adjustment value
+ for the payload. The new --cpu-affinity= switch controls the CPU
+ affinity of the container payload. The new --resolv-conf= switch
+ allows more detailed control of /etc/resolv.conf handling of the
+ container. Similarly, the new --timezone= switch allows more detailed
+ control of /etc/localtime handling of the container.
+
+ * systemd-detect-virt gained a new --list switch, which will print a
+ list of all currently known VM and container environments.
+
+ * Support for "Portable Services" has been added, see
+ doc/PORTABLE_SERVICES.md for details. Currently, the support is still
+ experimental, but this is expected to change soon. Reflecting this
+ experimental state, the "portablectl" binary is not installed into
+ /usr/bin yet. The binary has to be called with the full path
+ /usr/lib/systemd/portablectl instead.
+
+ * journalctl's and systemctl's -o switch now knows a new log output
+ mode "with-unit". The output it generates is very similar to the
+ regular "short" mode, but displays the unit name instead of the
+ syslog tag for each log line. Also, the date is shown with timezone
+ information. This mode is probably more useful than the classic
+ "short" output mode for most purposes, except where pixel-perfect
+ compatibility with classic /var/log/messages formatting is required.
+
+ * A new --dump-bus-properties switch has been added to the systemd
+ binary, which may be used to dump all supported D-Bus properties.
+ (Options which are still supported, but are deprecated, are *not*
+ shown.)
+
+ * sd-bus gained a set of new calls:
+ sd_bus_slot_set_floating()/sd_bus_slot_get_floating() may be used to
+ enable/disable the "floating" state of a bus slot object,
+ i.e. whether the slot object pins the bus it is allocated for into
+ memory or if the bus slot object gets disconnected when the bus goes
+ away. sd_bus_open_with_description(),
+ sd_bus_open_user_with_description(),
+ sd_bus_open_system_with_description() may be used to allocate bus
+ objects and set their description string already during allocation.
+
+ * sd-event gained support for watching inotify events from the event
+ loop, in an efficient way, sharing inotify handles between multiple
+ users. For this a new function sd_event_add_inotify() has been added.
+
+ * sd-event and sd-bus gained support for calling special user-supplied
+ destructor functions for userdata pointers associated with
+ sd_event_source, sd_bus_slot, and sd_bus_track objects. For this new
+ functions sd_bus_slot_set_destroy_callback,
+ sd_bus_slot_get_destroy_callback, sd_bus_track_set_destroy_callback,
+ sd_bus_track_get_destroy_callback,
+ sd_event_source_set_destroy_callback,
+ sd_event_source_get_destroy_callback have been added.
+
+ * The "net.ipv4.tcp_ecn" sysctl will now be turned on by default.
+
+ * PID 1 will now automatically reschedule .timer units whenever the
+ local timezone changes. (They previously got rescheduled
+ automatically when the system clock changed.)
+
+ * New documentation has been added to document cgroups delegation,
+ portable services and the various code quality tools we have set up:
+
+ https://github.com/systemd/systemd/blob/master/doc/CGROUP_DELEGATION.md
+ https://github.com/systemd/systemd/blob/master/doc/PORTABLE_SERVICES.md
+ https://github.com/systemd/systemd/blob/master/doc/CODE_QUALITY.md
+
+ * pam_systemd will now look for PAM userdata fields systemd.memory_max,
+ systemd.tasks_max, systemd.cpu_weight, systemd.io_weight set by
+ earlier PAM modules. The data in these fields is used to initialize
+ the session scope's resource properties. Thus external PAM modules
+ may now configure per-session limits, for example sourced from
+ external user databases.
+
+ * socket units with Accept=yes will now maintain a "refused" counter in
+ addition to the existing "accepted" counter, counting connections
+ refused due to the enforced limits.
+
+ * The "systemd-path search-binaries-default" command may now be use to
+ query the default, built-in $PATH PID 1 will pass to the services it
+ manages.
+
+ * A new unit file setting PrivateMounts= has been added. It's a boolean
+ option. If enabled the unit's processes are invoked in their own file
+ system namespace. Note that this behaviour is also implied if any
+ other file system namespacing options (such as PrivateTmp=,
+ PrivateDevices=, ProtectSystem=, …) are used. This option is hence
+ primarily useful for services that do not use any of the other file
+ system namespacing options. One such service is systemd-udevd.service
+ wher this is now used by default.

+
+CHANGES WITH 238:
+
+ * The MemoryAccounting= unit property now defaults to on. After
+ discussions with the upstream control group maintainers we learnt
+ that the negative impact of cgroup memory accounting on current
+ kernels is finally relatively minimal, so that it should be safe to
+ enable this by default without affecting system performance. Besides
+ memory accounting only task accounting is turned on by default, all
+ other forms of resource accounting (CPU, IO, IP) remain off for now,
+ because it's not clear yet that their impact is small enough to move
+ from opt-in to opt-out. We recommend downstreams to leave memory
+ accounting on by default if kernel 4.14 or higher is primarily
+ used. On very resource constrained systems or when support for old
+ kernels is a necessity, -Dmemory-accounting-default=false can be used
+ to revert this change.
+
+ * rpm scriptlets to update the udev hwdb and rules (%udev_hwdb_update,
+ %udev_rules_update) and the journal catalog (%journal_catalog_update)
+ from the upgrade scriptlets of individual packages now do nothing.
+ Transfiletriggers have been added which will perform those updates
+ once at the end of the transaction.
+
+ Similar transfiletriggers have been added to execute any sysctl.d
+ and binfmt.d rules. Thus, it should be unnecessary to provide any
+ scriptlets to execute this configuration from package installation
+ scripts.
+
+ * systemd-sysusers gained a mode where the configuration to execute is
+ specified on the command line, but this configuration is not executed
+ directly, but instead it is merged with the configuration on disk,
+ and the result is executed. This is useful for package installation
+ scripts which want to create the user before installing any files on
+ disk (in case some of those files are owned by that user), while
+ still allowing local admin overrides.
+
+ This functionality is exposed to rpm scriptlets through a new
+ %sysusers_create_package macro. Old %sysusers_create and
+ %sysusers_create_inline macros are deprecated.
+
+ A transfiletrigger for sysusers.d configuration is now installed,
+ which means that it should be unnecessary to call systemd-sysusers from
+ package installation scripts, unless the package installs any files
+ owned by those newly-created users, in which case
+ %sysusers_create_package should be used.
+
+ * Analogous change has been done for systemd-tmpfiles: it gained a mode
+ where the command-line configuration is merged with the configuration
+ on disk. This is exposed as the new %tmpfiles_create_package macro,
+ and %tmpfiles_create is deprecated. A transfiletrigger is installed
+ for tmpfiles.d, hence it should be unnecessary to call systemd-tmpfiles
+ from package installation scripts.
+
+ * sysusers.d configuration for a user may now also specify the group
+ number, in addition to the user number ("u username 123:456"), or
+ without the user number ("u username -:456").
+
+ * Configution items for systemd-sysusers can now be specified as
+ positional arguments when the new --inline switch is used.
+
+ * The login shell of users created through sysusers.d may now be
+ specified (previously, it was always /bin/sh for root and
+ /sbin/nologin for other users).
+
+ * systemd-analyze gained a new --global switch to look at global user
+ configuration. It also gained a unit-paths verb to list the unit load
+ paths that are compiled into systemd (which can be used with
+ --systemd, --user, or --global).
+
+ * udevadm trigger gained a new --settle/-w option to wait for any
+ triggered events to finish (but just those, and not any other events
+ which are triggered meanwhile).
+
+ * The action that systemd-logind takes when the lid is closed and the
+ machine is connected to external power can now be configured using
+ HandleLidSwitchExternalPower= in logind.conf. Previously, this action
+ was determined by HandleLidSwitch=, and, for backwards compatibility,
+ is still is, if HandleLidSwitchExternalPower= is not explicitly set.
+
+ * journalctl will periodically call sd_journal_process() to make it
+ resilient against inotify queue overruns when journal files are
+ rotated very quickly.
+
+ * Two new functions in libsystemd — sd_bus_get_n_queued_read and
+ sd_bus_get_n_queued_write — may be used to check the number of
+ pending bus messages.
+
+ * systemd gained a new
+ org.freedesktop.systemd1.Manager.AttachProcessesToUnit dbus call
+ which can be used to migrate foreign processes to scope and service
+ units. The primary user for this new API is systemd itself: the
+ systemd --user instance uses this call of the systemd --system
+ instance to migrate processes if it itself gets the request to
+ migrate processes and the kernel refuses this due to access
+ restrictions. Thanks to this "systemd-run --scope --user …" works
+ again in pure cgroups v2 environments when invoked from the user
+ session scope.
+
+ * A new TemporaryFileSystem= setting can be used to mask out part of
+ the real file system tree with tmpfs mounts. This may be combined
+ with BindPaths= and BindReadOnlyPaths= to hide files or directories
+ not relevant to the unit, while still allowing some paths lower in
+ the tree to be accessed.
+
+ ProtectHome=tmpfs may now be used to hide user home and runtime
+ directories from units, in a way that is mostly equivalent to
+ "TemporaryFileSystem=/home /run/user /root".
+
+ * Non-service units are now started with KeyringMode=shared by default.
+ This means that mount and swapon and other mount tools have access
+ to keys in the main keyring.
+
+ * /sys/fs/bpf is now mounted automatically.
+
+ * QNX virtualization is now detected by systemd-detect-virt and may
+ be used in ConditionVirtualization=.
+
+ * IPAccounting= may now be enabled also for slice units.
+
+ * A new -Dsplit-bin= build configuration switch may be used to specify
+ whether bin and sbin directories are merged, or if they should be
+ included separately in $PATH and various listings of executable
+ directories. The build configuration scripts will try to autodetect
+ the proper values of -Dsplit-usr= and -Dsplit-bin= based on build
+ system, but distributions are encouraged to configure this
+ explicitly.
+
+ * A new -Dok-color= build configuration switch may be used to change
+ the colour of "OK" status messages.
+
+ * UPGRADE ISSUE: serialization of units using JoinsNamespaceOf= with
+ PrivateNetwork=yes was buggy in previous versions of systemd. This
+ means that after the upgrade and daemon-reexec, any such units must
+ be restarted.
+
+ * INCOMPATIBILITY: as announced in the NEWS for 237, systemd-tmpfiles
+ will not exclude read-only files owned by root from cleanup.

+
+CHANGES WITH 237:
* Some keyboards come with a zoom see-saw or rocker which until now got
mapped to the Linux "zoomin/out" keys in hwdb. However, these
don't exist yet, and only then the argument string is written to the
file.
+ * FUTURE INCOMPATIBILITY: In systemd v238 we intend to slightly change
+ systemd-tmpfiles behaviour: previously, read-only files owned by root
+ were always excluded from the file "aging" algorithm (i.e. the
+ automatic clean-up of directories like /tmp based on
+ atime/mtime/ctime). We intend to drop this restriction, and age files
+ by default even when owned by root and read-only. This behaviour was
+ inherited from older tools, but there have been requests to remove
+ it, and it's not obvious why this restriction was made in the first
+ place. Please speak up now, if you are aware of software that reqires
+ this behaviour, otherwise we'll remove the restriction in v238.
+
* A new environment variable $SYSTEMD_OFFLINE is now understood by
systemctl. It takes a boolean argument. If on, systemctl assumes it
operates on an "offline" OS tree, and will not attempt to talk to the
chroot() environment was detected, and this new environment variable
now provides explicit control.
- * .path and .socket units may now be created transiently,
- too. Previously only service, mount, automount and timer units were
+ * .path and .socket units may now be created transiently, too.
+ Previously only service, mount, automount and timer units were
supported as transient units. The systemd-run tool has been updated
to expose this new functionality, you may hence use it now to bind
arbitrary commands to path or socket activation on-the-fly from the
- command line. Moreover, for the unit types already supporting
- transient operation most properties are now hooked up.
+ command line. Moreover, almost all properties are now exposed for the
+ unit types that already supported transient operation.
* The systemd-mount command gained support for a new --owner= parameter
which takes a user name, which is then resolved and included in uid=
described above. Synthesizing of this message has to be requested
explicitly through the new API call sd_bus_set_connected_signal(). In
addition a new call sd_bus_is_ready() has been added that checks
- wether a connection is fully set up (i.e. between the "Connected" and
+ whether a connection is fully set up (i.e. between the "Connected" and
"Disconnected" signals).
* sd-bus gained two new calls sd_bus_request_name_async() and
user/UID to use for notification messages sent to the service
manager.
- * There's now a "systemd-analyze service-watchdogs" command for turning
- on or off the per-service watchdogs system-wide (i.e. the concept you
- configure in WatchdogSec=), for debugging purposes. There's also a
- kernel command line option systemd.service_watchdogs= for controlling
- the same.
+ * journalctl gained a new --grep= option to list only entries in which
+ the message matches a certain pattern. By default matching is case
+ insensitive if the pattern is lowercase, and case sensitive
+ otherwise. Option --case-sensitive=yes|no can be used to override
+ this an specify case sensitivity or case insensitivity.
+
+ * There's now a "systemd-analyze service-watchdogs" command for printing
+ the current state of the service runtime watchdog, and optionally
+ enabling or disabling the per-service watchdogs system-wide if given a
+ boolean argument (i.e. the concept you configure in WatchdogSec=), for
+ debugging purposes. There's also a kernel command line option
+ systemd.service_watchdogs= for controlling the same.
+
+ * Two new "log-level" and "log-target" options for systemd-analyze were
+ added that merge the now deprecated get-log-level, set-log-level and
+ get-log-target, set-log-target pairs. The deprecated options are still
+ understood for backwards compatibility. The two new options print the
+ current value when no arguments are given, and set them when a
+ level/target is given as an argument.
+
+ * sysusers.d's "u" lines now optionally accept both a UID and a GID
+ specification, separated by a ":" character, in order to create users
+ where UID and GID do not match.

anyway.
- * A new document UIDS-GIDS.md has been added to the source tree, that
- documents the UID/GID range and assignment assumptions and
+ * A new document doc/UIDS-GIDS.md has been added to the source tree,
+ that documents the UID/GID range and assignment assumptions and
requirements of systemd.
* The watchdog device PID 1 will ping may now be configured through the
(domain search list).
* systemd-networkd gained support for serving IPv6 address ranges using
- the Router Advertisment protocol. The new .network configuration
+ the Router Advertisement protocol. The new .network configuration
section [IPv6Prefix] may be used to configure the ranges to
serve. This is implemented based on a new, minimal, native server
implementation of RA.
* Documentation has been added that lists all of systemd's low-level
environment variables:

* sd-daemon gained a new API sd_is_socket_sockaddr() for determining
whether a specific socket file descriptor matches a specified socket
counted multiple times, if it takes multiple references.
* sd-bus gained new API calls sd_bus_set_exit_on_disconnect() and
