+Features
+========
+
+ * Arch Linux package format support got added.
+
+ * Build Job Constraints handling. It can be used to define build
+   instance requirements for certain build jobs. Either for defined
+   package sources or for all repositories.
+
+   Documentation about this can be found here:
+
+    http://openbuildservice.org/help/manuals/obs-reference-guide/cha.obs.build_job_constraints.html
+
+ * Support of preinstall images, which can be used to speed up build
+   jobs. They need to be build manually, but get automatically used for
+   creating a build instance base in a faster way than just with installing
+   packages.
+
+ * Static links (without version and release numbers) for binary results 
+   in the published repositories can be configured now. This can be done via
+   the "staticlinks" keyword in Repotype: definition.
+
+ * Data about used resources of build jobs get collected. However it
+   gets not yet used for build job assignment
+
+ * Requests can be listed also for given groups now.
+
+ * Checkout of delete packages does not require a srcmd5 sum anymore.
+
+ * Delete Requests can be used to request deletion of repositories from 
+   a project.
+
+ * Support of creation of application data xml which can be used for app 
+   stores for application centric browsing versus package browsing.
+
+ * Support hugetable memory usage for kvm workers.
+
+ * Support building cross build formats, eg. building an rpm with a kiwi 
+   build description or an deb package via a .spec file.
+
+ * Efficient transport of product build results from worker to backend.
