systemd System and Service Manager
+CHANGES WITH 255 in spe:
+
+ Announcements of Future Feature Removals and Incompatible Changes:
+
+ * Support for split-usr (/usr/ mounted separately during late boot,
+ instead of being mounted by the initrd before switching to the rootfs)
+ and unmerged-usr (parallel directories /bin/ and /usr/bin/, /lib/ and
+ /usr/lib/, …) has been removed. For more details, see:
+ https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html
+
+ * We intend to remove cgroup v1 support from a systemd release after
+ the 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 "unified hierarchy") sooner rather than later.
+ Most of Linux userspace has been ported over already.
+
+ * Support for System V service scripts is now 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.
