+v2.0.0 - 15 Oct 2013

 ---------------------
 ---------------------

+    - The ovs-vswitchd process is no longer single-threaded.  Multiple
+      threads are now used to handle flow set up and asynchronous
+      logging.
+    - OpenFlow:
+      * Experimental support for OpenFlow 1.1 (in addition to 1.2 and
+        1.3, which had experimental support in 1.10).
+      * New support for matching outer source and destination IP address
+        of tunneled packets, for tunnel ports configured with the newly
+        added "remote_ip=flow" and "local_ip=flow" options.
+      * Support for matching on metadata 'pkt_mark' for interacting with
+        other system components. On Linux this corresponds to the skb
+        mark.
+      * Support matching, rewriting SCTP ports
+    - The Interface table in the database has a new "ifindex" column to
+      report the interface's OS-assigned ifindex.
+    - New "check-oftest" Makefile target for running OFTest against Open
+      vSwitch.  See README-OFTest for details.
+    - The flow eviction threshold has been moved to the Open_vSwitch table.
+    - Database names are now mandatory when specifying ovsdb-server options
+      through database paths (e.g. Private key option with the database name
+      should look like "--private-key=db:Open_vSwitch,SSL,private_key").
+    - Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
+    - Support for Linux kernels up to 3.10
+    - ovs-ofctl:
+      * New "ofp-parse" for printing OpenFlow messages read from a file.
+    - Added configurable flow caching support to IPFIX exporter.
+    - Dropped support for Linux pre-2.6.32.
+    - Log file timestamps and ovsdb commit timestamps are now reported
+      with millisecond resolution.  (Previous versions only reported
+      whole seconds.)
+
+
+v1.11.0 - 28 Aug 2013
+---------------------
+    - Support for megaflows, which allows wildcarding in the kernel (and
+      any dpif implementation that supports wildcards).  Depending on
+      the flow table and switch configuration, flow set up rates are
+      close to the Linux bridge.
+    - The "tutorial" directory contains a new tutorial for some advanced
+      Open vSwitch features.

     - Stable bond mode has been removed.
     - The autopath action has been removed.
     - New support for the data encapsulation format of the LISP tunnel

+      the "enable-protocol" command that can be used as an alternative.
+    - New CFM demand mode which uses data traffic to indicate interface
+      liveness.
