 Q: What versions of OpenFlow does Open vSwitch support?
 
-A: Open vSwitch supports OpenFlow 1.0.  It also includes a number of
-   extensions that bring many of the features from later versions of
-   OpenFlow.  Work is underway to provide support for later versions and
-   can be tracked here:
+A: Open vSwitch 1.9 and earlier support only OpenFlow 1.0 (plus
+   extensions that bring in many of the features from later versions
+   of OpenFlow).
 
-       http://openvswitch.org/development/openflow-1-x-plan/
+   Open vSwitch versions 1.10 and later will have experimental support
+   for OpenFlow 1.2 and 1.3.  On these versions of Open vSwitch, the
+   following command enables OpenFlow 1.0, 1.2, and 1.3 on bridge br0:
+
+       ovs-vsctl set bridge br0 protocols=openflow10,openflow12,openflow13
+
+   Support for OpenFlow 1.1 is incomplete enough that it cannot yet be
+   enabled, even experimentally.
+
+   Support for OpenFlow 1.2 and 1.3 is still incomplete.  Work to be
+   done is tracked in OPENFLOW-1.1+ in the Open vSwitch source tree
+   (also via http://openvswitch.org/development/openflow-1-x-plan/).
+   When support for a given OpenFlow version is solidly implemented,
+   Open vSwitch will enable that version by default.
