systemd System and Service Manager
+CHANGES WITH 197:
+
+ * Timer units now support calendar time events in addition to
+ monotonic time events. That means you can now trigger a unit
+ based on a calendar time specification such as "Thu,Fri
+ 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first
+ or fifth day of any month of the year 2013, given that it is
+ a thursday or friday. This brings timer event support
+ considerably closer to cron's capabilities. For details on
+ the supported calendar time specification language see
+ systemd.time(7).
+
+ * udev now supports a number of different naming policies for
+ network interfaces for predictable names, and a combination
+ of these policies is now the default. Please see this wiki
+ document for details:
+
+ http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames
+
+ * Auke Kok's bootchart implementation has been added to the
+ systemd tree. It's an optional component that can graph the
+ boot in quite some detail. It's one of the best bootchart
+ implementations around and minimal in its code and
+ dependencies.
+
+ * nss-myhostname has been integrated into the systemd source
+ tree. nss-myhostname guarantees that the local hostname
+ always stays resolvable via NSS. It has been a weak
+ requirement of systemd-hostnamed since a long time, and
+ since its code is actually trivial we decided to just
+ include it in systemd's source tree. It can be turned off
+ with a configure switch.
+
+ * The read-ahead logic is now capable of properly detecting
+ whether a btrfs file system is on SSD or rotating media, in
+ order to optimize the read-ahead scheme. Previously, it was
+ only capable of detecting this on traditional file systems
+ such as ext4.
+
+ * In udev, additional device properties are now read from the
+ IAB in addition to the OUI database. Also, Bluetooth company
+ identities are attached to the devices as well.
+
+ * In service files %U may be used as specifier that is
+ replaced by the configured user name of the service.
+
+ * nspawn may now be invoked without a controlling TTY. This
+ makes it suitable for invocation as its own service. This
+ may be used to set up a simple containerized server system
+ using only core OS tools.
+
+ * systemd and nspawn can now accept socket file descriptors
+ when they are started for socket activation. This enables
+ implementation of socket activated nspawn
+ containers. i.e. think about autospawning an entire OS image
+ when the first SSH or HTTP connection is received. We expect
+ that similar functionality will also be added to libvirt-lxc
+ eventually.
+
+ * journalctl will now suppress ANSI color codes when
+ presenting log data.
+
+ * systemctl will no longer show control group information for
+ a unit if a the control group is empty anyway.
+
+ * logind can now automatically suspend/hibernate/shutdown the
+ system on idle.
+
+ * /etc/machine-info and hostnamed now also expose the chassis
+ type of the system. This can be used to determine whether
+ the local system is a laptop, desktop, handset or
+ tablet. This information may either be configured by the
+ user/vendor or is automatically determined from ACPI and DMI
+ information if possible.
+
+ * A number of PolicyKit actions are now bound together with
+ "imply" rules. This should simplify creating UIs because
+ many actions will now authenticate similar ones as well.
+
+ * Unit files learnt a new condition ConditionACPower= which
+ may be used to conditionalize a unit depending on whether an
+ AC power source is connected or not, of whether the system
+ is running on battery power.
+
+ * systemctl gained a new "is-failed" verb that may be used in
+ shell scripts and suchlike to check whether a specific unit
+ is in the "failed" state.
+
+ * The EnvironmentFile= setting in unit files now supports file
+ globbing, and can hence be used to easily read a number of
+ environment files at once.
+
+ * systemd will no longer detect and recognize specific
+ distributions. All distribution-specific #ifdeffery has been
+ removed, systemd is now fully generic and
+ distribution-agnostic. Effectively, not too much is lost as
+ a lot of the code is still accessible via explicit configure
+ switches. However, support for some distribution specific
+ legacy configuration file formats has been dropped. We
+ recommend distributions to simply adopt the configuration
+ files everybody else uses now and convert the old
+ configuration from packaging scripts. Most distributions
+ already did that. If that's not possible or desirable,
+ distributions are welcome to forward port the specific
+ pieces of code locally from the git history.
+
+ * When logging a message about a unit systemd will now always
+ log the unit name in the message meta data.
+
+ * localectl will now also discover system locale data that is
+ not stored in locale archives, but directly unpacked.
+
+ * logind will no longer unconditionally use framebuffer
+ devices as seat masters, i.e. as devices that are required
+ to be existing before a seat is considered preset. Instead,
+ it will now look for all devices that are tagged as
+ "seat-master" in udev. By default framebuffer devices will
+ be marked as such, but depending on local systems other
+ devices might be marked as well. This may be used to
+ integrate graphics cards using closed source drivers (such
+ as NVidia ones) more nicely into logind. Note however, that
+ we recommend using the open source NVidia drivers instead,
+ and no udev rules for the closed-source drivers will be
+ shipped from us upstream.

CHANGES WITH 196:
* udev gained support for loading additional device properties
the longer run this indexed database shall grow into
becoming the one central database for non-essential
userspace device metadata. Previously, data from the PCI/USB
- database was only attached to the select devices, since the
+ database was only attached to select devices, since the
lookup was a relatively expensive operation due to O(n) time
- complexity. Since this is now O(log(n)), we decided to add
- in this data for all devices where this is available, by
+ complexity (with n being the number of entries in the
+ database). Since this is now O(1), we decided to add in this
+ data for all devices where this is available, by
default. Note that the indexed database needs to be rebuilt
when new data files are installed. To achieve this you need
to update your packaging scripts to invoke "udevadm hwdb
