systemd System and Service Manager
+CHANGES WITH 228:
+
+ * When creating transient services via the bus API it is now
+ possible to pass in a set of file descriptors to use as
+ STDIN/STDOUT/STDERR for the invoked process.
+
+ * A number of properties previously only settable in unit
+ files are now also available as properties to set when
+ creating transient units programmatically via the bus, as it
+ is exposed with systemd-run's --property=
+ setting. Specifically, these are: SyslogIdentifier=,
+ SyslogLevelPrefix=, TimerSlackNSec=, OOMScoreAdjust=,
+ EnvironmentFile=, ReadWriteDirectories=,
+ ReadOnlyDirectories=, InaccessibleDirectories=,
+ ProtectSystem=, ProtectHome=, RuntimeDirectory=.
+
+ * Any reference to /etc/mtab has been dropped from
+ systemd. The file has been obsolete since a while, but
+ systemd refused to work on systems where it was incorrectly
+ set up (it should be a symlink or non-existant). Please make
+ sure to update to util-linux 2.27.1 or newer in conjunction
+ with this systemd release, which also drops any reference to
+ /etc/mtab. If you maintain a distribution make sure that no
+ software you package still references it, as this is a
+ likely source of bugs. There's also a glibc bug pending,
+ asking for removal of any reference to the file:
+
+ https://sourceware.org/bugzilla/show_bug.cgi?id=19108
+
+ * The compression framing format used by the journal or
+ coredump processing has changed to be in line with what the
+ official LZ4 tools generate. LZ4 compression support in
+ systemd was considered unsupported previously, as the format
+ was not compatible with the normal tools. With this release
+ this has changed now, and it is hence safe for downstream
+ distributions to turn it on. While not compressing as well
+ as the XZ,LZ4 is substantially faster, which makes
+ it a good default choice for the compression logic in the
+ journal and in coredump handling.
+
+ * Wherever systemd expects a calendar timestamp specification
+ (like in journalctl's --since= and --until= switches) UTC
+ timestamps are now supported. Timestamps suffixed with "UTC"
+ are now considered to be in Universal Time Coordinated
+ instead of the local timezone. Also, timestamps may now
+ optionally be specified with a sub-second accuracy. Both of
+ these additions also apply to recurring calendar event
+ specification, such as OnCalendar= in timer units.
+
+ * systemd-tmpfiles learned two new line types "q" and "Q" that
+ operate like "v", but also set up a basic btrfs quota
+ hierarchy when used on a btrfs file system with quota
+ enabled.
+
+ * systemd-detect-virt gained a new --chroot switch to detect
+ whether execution takes place in a chroot() environment.
+
+ * CPUAffinity= now takes CPU index ranges in addition to just
+ individual indexes.
+
+ * systemd will now bump the net.unix.max_dgram_qlen to 512 by
+ default now (kernel default is 16). This is beneficial for
+ avoiding blocking on AF_UNIX/SOCK_DGRAM sockets since it
+ allows substantially larger numbers of queued
+ datagrams. This should increase the capability of systemd to
+ parallelize boot-up, as logging and sd_notify() are unlikely
+ to stall execution anymore. If you need to change the value
+ from the new defaults, use the usual sysctl.d/ snippets.
+
+ * The various memory-related resource limit settings (such as
+ LimitAS=) now understand the usual K, M, G, ... suffixes to
+ the base of 1024 (IEC). Similar, the time-related settings
+ understand the usual min, h, day, ... suffixes now.
+
+ * journalctl gained a new "--sync" switch that asks the
+ journal daemon to write all so far unwritten log messages to
+ disk and sync the files, before returning.
+
+ * Support for the ".snapshot" unit type has been removed. This
+ feature turned out to be little useful and little used, and
+ has now been removed from the core and from systemctl.
+
+ * A new service execution setting PassEnvironment= has been
+ added that allows importing select environment variables
+ from PID1's environment block into the environment block of
+ the service.
+
CHANGES WITH 227:
* systemd now depends on util-linux v2.27. More specifically,
