NEWS: add a bunch of stuff for the 232 release (#4132)
This does not include the description of the mixed v1/v2 mode, but everything important apart from that should be covered.

CHANGES WITH 232 in spe
+ * The new RemoveIPC= option can be used to remove IPC objects owned by
+ the user or group of a service when that service exits.
+
+ * Support for dynamically creating users for the lifetime of a service
+ has been added. If DynamicUser=yes is specified, user and group IDs
+ will be allocated from the range 61184..65519 for the lifetime of the
+ service. They can be resolved using the new nss-systemd.so NSS
+ module. The module must be enabled in /etc/nsswitch.conf. Services
+ started in this way have PrivateTmp= and RemoveIPC= enabled, so that
+ any resources allocated by the service will be cleaned up when the
+ service exits.
+
+ The nss-systemd module also always resolves root and nobody, making
+ it possible to have no /etc/passwd or /etc/group files in minimal
+ container systems.
+
+ * Services may be started with their own user namespace using the new
+ PrivateUsers= option. Only root, nobody, and the uid/gid under which
+ the service is running are mapped. All other users are mapped to
+ nobody.
+
+ * Support for the cgroup namespace has been added to systemd-nspawn. If
+ supported by kernel, the container system started by systemd-nspawn
+ will have its own view of the cgroup hierarchy. This new behaviour
+ can be disabled using $SYSTEMD_NSPAWN_USE_CGNS environment variable.
+
+ * The new MemorySwapMax= option can be used to limit the maximum swap
+ usage under the unified cgroup hierarchy.
+
+ * Support for the CPU controller in the unified cgroup hierarchy has
+ been added, via the CPUWeight=, CPUStartupWeight=, CPUAccounting=
+ options. This controller requires out-of-tree patches for the kernel
+ and the support is provisional.
+
+ * .automount units may now be transient.
+
+ * systemd-mount is a new tool which wraps mount(8) to pull in
+ additional dependencies through transient .mount and .automount
+ units. For example, this automatically runs fsck on the block device
+ before mounting, and allows the automount logic to be used.
+
+ * LazyUnmount=yes option for mount units has been added to expose the
+ umount --lazy option. Similarly, ForceUnmount=yes exposes the --force
+ option.
+
+ * /efi will be used as the mount point of the EFI boot partition, if
+ the directory is present, and the mount point was not configured
+ through other means (e.g. fstab). If /efi directory does not exist,
+ /boot will be used as before. This makes it easier to automatically
+ mount the EFI partition on systems where /boot is used for something
+ else.
+
+ * disk/by-id symlinks are now created for NVMe drives.
+
+ * Two new user session targets have been added to support running
+ graphical sessions under the systemd --user instance:
+ graphical-session.target and graphical-session-pre.target. See
+ systemd.special(7) for a description of how those targets should be
+ used.
+
+ * The vconsole initialization code has been significantly reworked to
+ use KD_FONT_OP_GET/SET ioctls insteads of KD_FONT_OP_COPY and better
+ support unicode keymaps. Font and keymap configuration will now be
+ copied to all allocated virtual consoles.
+
+ * FreeBSD's bhyve virtiualization is now detected.
+
+ * Information recored in the journal for core dumps now includes the
+ contents of /proc/mountinfo and the command line of the process at
+ the top of the process hierarchy (which is usually the init process
+ of the container).
+
+ * systemd-journal-gatewayd learned the --directory option to serve
+ files from the specified location.
+
+ * journalctl --root=… can be used to peruse the journal in the
+ /var/log/ directories inside of a container tree. This is similar to
+ the existing --machine= option, but does not require the container to
+ be active.
+
+ * The hardware database has been extended to support
+ ID_INPUT_TRACKBALL, used in addition to ID_INPUT_MOUSE to identify
+ trackball devices.
+
+ MOUSE_WHEEL_CLICK_ANGLE_HORIZONTAL hwdb property has been added to
+ specify the click rate for mice which include a horizontal wheel with
+ a click rate that is different than the one for the vertical wheel.
+
+ * systemd-run gained a new --wait option that makes service execution
+ synchronous.
+
+ * A new journal output mode "short-full" has been added which uses
+ timestamps with abbreviated English day names and adds a timezone
+ suffix. Those timestamps include more information and can be parsed
+ by journalctl.
+
+ * /etc/resolv.conf will be bind-mounted into containers started by
+ systemd-nspawn, if possible, so any changes to resolv.conf contents
+ are automatically propagated to the container.
+
+ * The number of instances for socket-activated services originating
+ from a single IP can be limited with MaxConnectionsPerSource=,
+ extending the existing setting of MaxConnections.
+
+ * UDP Segmentation Offload, TCP Segmentation Offload, Generic
+ Segmentation Offload, Generic Receive Offload, Large Receive Offload
+ can be enabled and disabled using the new UDPSegmentationOffload=,
+ TCPSegmentationOffload=, GenericSegmentationOffload=,
+ GenericReceiveOffload=, LargeReceiveOffload= options in the
+ [Link] section of .link files.
+
+ Spanning Tree Protocol enablement, Priority, Aging Time, and the
+ Default Port VLAN ID can be configured for bridge devices using the
+ new STP=, Priority=, AgeingTimeSec=, and DefaultPVID= settings in the
+ [Bridge] section of .netdev files.
+
+ Address Resolution Protocol can be disabled on links managed by
+ systemd-networkd using the ARP=no setting in the [Link] section of
+ .network files.
+
+ * $SERVICE_RESULT, $EXIT_CODE, $EXIT_STATUS are set for ExecStop= and
+ ExecStopPost= commands.
+
* Journald's SplitMode=login setting has been deprecated. It has been
removed from documentation, and it's use is discouraged. In a future
release it will be completely removed, and made equivalent to current
default of SplitMode=uid.
+ * The --share-system systemd-nspawn option has been replaced with an
+ (undocumented) variable $SYSTEMD_NSPAWN_SHARE_SYSTEM, but the use of
+ this functionality is discouraged. In addition the variables
+ $SYSTEMD_NSPAWN_SHARE_NS_IPC, $SYSTEMD_NSPAWN_SHARE_NS_PID,
+ $SYSTEMD_NSPAWN_SHARE_NS_UTS may be used to control the unsharing of
+ individual namespaces.
