possible to pass in a set of file descriptors to use as
STDIN/STDOUT/STDERR for the invoked process.
+ * Slice units may now be created transiently via the bus APIs,
+ similar to the way service and scope units may already be
+ created transiently.
+
* Wherever systemd expects a calendar timestamp specification
(like in journalctl's --since= and --until= switches) UTC
timestamps are now supported. Timestamps suffixed with "UTC"

hierarchy when used on a btrfs file system with quota
enabled.
+ * tmpfiles' "v", "q" and "Q" will now create a plain directory
+ instead of a subvolume (even on a btrfs file system) if the
+ root directory is a plain directory, and not a
+ subvolume. This should simplify things with certain chroot()
+ environments which are not aware of the concept of btrfs
+ subvolumes.
+
* systemd-detect-virt gained a new --chroot switch to detect
whether execution takes place in a chroot() environment.

limit settings understand the usual min, h, day, ...
suffixes now.
+ * There's a new system.conf setting DefaultTasksMax= to
+ control the default TasksMax= setting for services and
+ scopes running on the system. (TasksMax= is the primary
+ setting that exposes the "pids" cgroup controller on systemd
+ and was introduced in the previous systemd release.) The
+ setting now defaults to 512, which means services that are
+ not explicitly configured otherwise will only be able to
+ create 512 processes or threads at maximum, from this
+ version on. Note that this means that thread- or
+ process-heavy services might need to be reconfigured to set
+ TasksMax= to a higher value. It is sufficient to set
+ TasksMax= in these specific unit files to a higher value, or
+ even "infinity". Similar, there's now a logind.conf setting
+ UserTasksMax= that defaults to 4096 and limits the total
+ number of processes or tasks each user may own
+ concurrently. nspawn containers also have the TasksMax=
+ value set by default now, to 8192. Note that all of this
+ only has an effect if the "pids" cgroup controller is
+ enabled in the kernel. The general benefit of these changes
+ should be a more robust and safer system, that provides a
+ certain amount of per-service fork() bomb protection.
+
* systemd-nspawn gained the new --network-veth-extra= switch
to define additional and arbitrarily-named virtual Ethernet
links between the host and the container.
