systemd (253~rc2-1) experimental; urgency=medium

  TuxOnIce is no longer supported directly (via an out-of-tree patch)
  for hibernation. TuxOnIce users should instead use the environment
  variable $SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1 (i.e.: set it on
  the kernel command line).

  The Debian-specific /etc/default/locale will now be made into a
  symlink to the distribution-agnostic /etc/locale.conf. The content
  format is compatible, so at upgrade time if /etc/default/locale
  exists it will be copied to /etc/locale.conf, if the latter does not
  exist.
  The Debian-specific /etc/timezone will no longer be supported by
  systemd-timedated, as it is no longer useful and its functionality
  has been subsumed into /etc/localtime, and tzdata will no longer
  create it.

  The journal 'audit' feature is no longer patched to be disabled by
  default, and instead we rely on the fact that the unit
  'systemd-journald-audit.socket' is disabled by default. If you enabled
  this in the past by setting 'Audit=yes' in a configuration file, you
  will also need to enable the socket unit.

systemd (251.3-2) unstable; urgency=medium

  systemd-resolved has been split into a separate package.
  This new systemd-resolved package will not be installed automatically on
  upgrades. If you are using systemd-resolved, please install this new
  package manually.

systemd (251.2-3) unstable; urgency=medium

  systemd-boot has been split into a separate package.
  This new systemd-boot package will not be installed automatically on
  upgrades. If you are using systemd-boot, please install this new
  package manually.

  The default boot loader in Debian is grub2. If you have not set up
  systemd-boot manually, no action is required on your side.

systemd (251.1-1) unstable; urgency=medium

  systemd-journal-gatewayd and systemd-journal-remote are now built
  without the --trust option, in order to be able to switch away from
  gnutls to openssl.

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.
