+systemd (247.2-2) unstable; urgency=medium
+
+ systemd now defaults to the "unified" cgroup hierarchy (i.e. cgroupv2).
+ This change reflects the fact that cgroupsv2 support has matured
+ substantially in both systemd and in the kernel.
+ All major container tools nowadays should support cgroupv2.
+ If you run into problems with cgroupv2, you can switch back to the previous,
+ hybrid setup by adding "systemd.unified_cgroup_hierarchy=false" to the
+ kernel command line.
+ You can read more about the benefits of cgroupv2 at
+ https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html

+systemd (247.2-1) unstable; urgency=medium
+
+ KERNEL API INCOMPATIBILITY: Linux 4.14 introduced two new uevents
+ "bind" and "unbind" to the Linux device model. When this kernel
+ change was made, systemd-udevd was only minimally updated to handle
+ and propagate these new event types. The introduction of these new
+ uevents (which are typically generated for USB devices and devices
+ needing a firmware upload before being functional) resulted in a
+ number of issues which we so far didn't address. We hoped the kernel
+ maintainers would themselves address these issues in some form, but
+ that did not happen. To handle them properly, many (if not most) udev
+ rules files shipped in various packages need updating, and so do many
+ programs that monitor or enumerate devices with libudev or sd-device,
+ or otherwise process uevents. Please note that this incompatibility
+ is not fault of systemd or udev, but caused by an incompatible kernel
+ change that happened back in Linux 4.14, but is becoming more and
+ more visible as the new uevents are generated by more kernel drivers.
+
+ To learn more about the required udev rules changes please check the
+ "CHANGES WITH 247" section of /usr/share/doc/systemd/NEWS.gz.

+systemd (236-1) unstable; urgency=medium
+
+ DynamicUser=yes has been enabled for systemd-journal-upload.service and
+ systemd-journal-gatewayd.service.
+ This means we no longer need to statically allocate a systemd-journal-upload
+ and systemd-journal-gateway user and you can now safely remove those system
+ users along with their associated groups.

+
+systemd (231-1) unstable; urgency=low
+
+ This version drops support for running /etc/rcS.d SysV init scripts.
+ These are prone to cause dependency loops, and almost all Debian packages
+ with rcS scripts now ship a native systemd service. If you have custom or
+ third-party rcS scripts you need to convert them or change them to run
+ in rc2.d/ - rc5.d/; see this page for details:
+ <https://wiki.debian.org/Teams/pkg-systemd/rcSMigration>.

+systemd (224-2) unstable; urgency=medium
+
+ This version splits out systemd-nspawn, systemd-machined, and machinectl
+ into the new "systemd-container" package. That now also enables
+ systemd-importd.
