Announcements of Future Feature Removals and Incompatible Changes:
* To work around limitations of X11's keyboard handling systemd's
keyboard mapping hardware database (hwdb.d/60-keyboard.hwdb) so far
mapped the microphone mute and touchpad on/off/toggle keys to the
function keys F20, F21, F22, F23 instead of their correct key
codes. This key code mangling will be removed in the next systemd
release v258. To maintain compatibility with X11 applications that
rely on the old function key code mappings, this mangling has now
been moved to the relevant X11 keyboard driver modules instead. Thus,
in order to ensure these keys continue to work as before make sure to
update the xf86-input-evdev and xf86-input-libinput packages to the
newest version before updating systemd to v258.
* Support for automatic flushing of the nscd user/group database caches
has been dropped.
* Support for cgroup v1 ('legacy' and 'hybrid' hierarchies) is now
considered obsolete and systemd by default will refuse to boot under
it. To forcibly reenable cgroup v1 support,
SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1 must be set on kernel command
line. The meson option 'default-hierarchy=' is also deprecated, i.e.
only cgroup v2 ('unified' hierarchy) can be selected as build-time
default.
* Support for System V service scripts is deprecated and will be
removed in a future release. Please make sure to update your software
*now* to include a native systemd unit file instead of a legacy
System V script to retain compatibility with future systemd releases.
* Support for the SystemdOptions EFI variable is deprecated.
'bootctl systemd-efi-options' will emit a warning when used. It seems
that this feature is little-used and it is better to use alternative
approaches like credentials and confexts. The plan is to drop support
altogether at a later point, but this might be revisited based on
user feedback.
* systemd-run's switch --expand-environment= which currently is disabled
by default when combined with --scope, will be changed in a future
release to be enabled by default.
* The FileDescriptorName= setting for socket units is now honored by
Accept=yes sockets too, where it was previously silently ignored and
"connection" was used unconditionally.

Announcements of Future Feature Removals:
* D-Bus method org.freedesktop.systemd1.StartAuxiliaryScope() becomes

deprecated because accounting data and such cannot be reasonably
