systemd System and Service Manager
+CHANGES WITH 200:
+
+ * The boot-time readahead implementation for rotating media
+ will now read the read-ahead data in multiple passes which
+ consist of all read requests made in equidistant time
+ intervals. This means instead of strictly reading read-ahead
+ data in its physical order on disk we now try to find a
+ middle ground between physical and access time order.
+
+ * /etc/os-release files gained a new BUILD_ID= field for usage
+ on operating systems that provide continuous builds of OS
+ images.

+
+CHANGES WITH 199:
+
+ * systemd-python gained an API exposing libsystemd-daemon.
+
+ * The SMACK setup logic gained support for uploading CIPSO
+ security policy.
+
+ * Behaviour of PrivateTmp=, ReadWriteDirectories=,
+ ReadOnlyDirectories= and InaccessibleDirectories= has
+ changed. The private /tmp and /var/tmp directories are now
+ shared by all processes of a service (which means
+ ExecStartPre= may now leave data in /tmp that ExecStart= of
+ the same service can still access). When a service is
+ stopped its temporary directories are immediately deleted
+ (normal clean-up with tmpfiles is still done in addition to
+ this though).
+
+ * By default, systemd will now set a couple of sysctl
+ variables in the kernel: the safe sysrq options are turned
+ on, IP route verification is turned on, and source routing
+ disabled. The recently added hardlink and softlink
+ protection of the kernel is turned on. These settings should
+ be reasonably safe, and good defaults for all new systems.
+
+ * The predictable network naming logic may now be turned off
+ with a new kernel command line switch: net.ifnames=0.
+
+ * A new libsystemd-bus module has been added that implements a
+ pretty complete D-Bus client library. For details see:
+
+ http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html
+
+ * journald will now explicitly flush the journal files to disk
+ at the latest 5min after each write. The file will then also
+ be marked offline until the next write. This should increase
+ reliability in case of a crash. The synchronization delay
+ can be configured via SyncIntervalSec= in journald.conf.
+
+ * There's a new remote-fs-setup.target unit that can be used
+ to pull in specific services when at least one remote file
+ system is to be mounted.
+
+ * There are new targets timers.target and paths.target as
+ canonical targets to pull user timer and path units in
+ from. This complements sockets.target with a similar
+ purpose for socket units.
+
+ * libudev gained a new call udev_device_set_attribute_value()
+ to set sysfs attributes of a device.
+
+ * The udev daemon now sets the default number of worker
+ processes executed in parallel based on the number of available
+ CPUs instead of the amount of available RAM. This is supposed
+ to provide a more reliable default and limit a too agressive
+ paralellism for setups with 1000s of devices connected.

CHANGES WITH 198:
* Configuration of unit files may now be extended via drop-in
themselves. More specifically, if the administrator wants to
change one value for a service file foobar.service he can
now do so by dropping in a configuration snippet into
- /etc/systemd/systemd/foobar.service.d/*.conf. The unit logic
+ /etc/systemd/system/foobar.service.d/*.conf. The unit logic
will load all these snippets and apply them on top of the
main unit configuration file, possibly extending or
overriding its settings. Using these drop-in snippets is
