+CHANGES WITH 257 in spe:
+
+        Announcements of Future Feature Removals and Incompatible Changes:
+
+        * Support for automatic flushing of the nscd user/group database caches
+          will be dropped in a future release.
+
+        * 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.
