Announcements of Future Feature Removals and Incompatible Changes:

end of 2023. If you run services that make explicit use of cgroup v1
features (i.e. the "legacy hierarchy" with separate hierarchies for
each controller), please implement compatibility with cgroup v2 (i.e.
* The service manager gained support for enqueuing POSIX signals to
services that carry an additional integer value, exposing the
- sigqueue() systemd call. This is accessible via new D-Bus calls

QueueSignalUnit() (and related), as well as in systemctl via the new
--kill-value= parameter.
it affects userspace only: the service manager shuts down the running
services and other units, then optionally switches into a new root
file system (mounted to /run/nextroot/), and then passes control to a
- systemd instace in the new file system which then starts the system

up again. The kernel is not rebooted and neither is hardware,
firmware or boot loader. It is a fast, lightweight mechanism to
quickly reset or update userspace, without the latency that a full

* The kernel-install script has been rewritten in C, and reuses much of
- the infrastructure of existing tools such as bootctl. Moreover it
- gained support for --root= and --image= switches, to operate relative
- to some root file system or DDI. It also gained --esp-path= and
- --boot-path= options to override the path to the ESP, and the $BOOT
- partition. Options --make-entry-directory= and --entry-token= have

* A new kernel-install plugin 60-ukify has been added which will
combine kernel/initrd locally into an UKI and sign them with a local
MemoryPressureThresholdSec= for configuring the PSI memory pressure
logic individually. If these options are used the

* systemd-analyze gained a new "malloc" verb that shows the output
generated by glibc's malloc_info() on services that support it. Right
gained a new call sd_session_get_start_time() for retrieving the time
the login session started. A new call sd_session_get_leader() has
been added to return the PID of the "leader" process of a session. A

- the time since when they most recently were logged in continously
- with at least one session.

* JSON user records gained a new set of fields capabilityAmbientSet and
capabilityBoundingSet which contain a list of POSIX capabilities to
CAP_WAKE_ALARM, thus allowing regular users who may log in locally to
resume from a system suspend via a timer. (see above)
- * The Session D-Bus objects systemd-logind provides gained a new
- SetTTY() method call for updating the TTY of a session after it has
- been allocated already. This is useful for SSH sessions which are
- typically allocated first, and for which a TTY is added in later.

* The sd-login API gained a new call sd_pid_notifyf_with_fds() which
combines the various other sd_pid_notify() flavours into one: takes a
status to the host, similar to local processes.
* systemd-run gained a new switch --expand-environment=no to disable
- server-side enviornment variable expansion in specified command
+ server-side environment variable expansion in specified command
lines.
* The systemd-system-update-generator has been update to also look for
used to configure additional mounts or swaps via the kernel command
line, in a format similar to /etc/fstab lines.
- * systemd-sysupdate' sysupdate.d/ drop-ins gained a new setting
+ * systemd-sysupdate's sysupdate.d/ drop-ins gained a new setting
PathRelativeTo=, which can be set to "esp", "xbootldr", "boot", in
which case the Path= setting is taken relative to the ESP or XBOOTLDR
partitions, rather than the system's root directory /. The relevant
