+   - Add bash command-line completion support for ovs-appctl/ovs-dpctl/
+     ovs-ofctl/ovsdb-tool commands.  Please check
+     utilities/ovs-command-compgen.INSTALL.md for how to use.

    - The "learn" action supports a new flag "delete_learned" that causes
      the learned flows to be deleted when the flow with the "learn" action
      is deleted.

+   - sflow now exports information about LACP-based bonds, port names, and
+     OpenFlow port numbers, as well as datapath performance counters.

    - ovs-dpctl functionality is now available for datapaths integrated
      into ovs-vswitchd, via ovs-appctl.  Some existing ovs-appctl
      commands are now redundant and will be removed in a future
      release.  See ovs-vswitchd(8) for details.
    - OpenFlow:
      * OpenFlow 1.5 (draft) extended registers are now supported.

+   - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because
+     MD5 is no longer secure and some operating systems have started to disable
+     it in OpenSSL.
+   - ovsdb-server: New OVSDB protocol extension allows inequality tests on
+     "optional scalar" columns.  See ovsdb-server(1) for details.
+   - ovs-vsctl now permits immutable columns in a new row to be modified in
+     the same transaction that creates the row.
+   - test-controller has been renamed ovs-testcontroller at request of users
+     who find it useful for testing basic OpenFlow setups.  It is still not
+     a necessary or desirable part of most Open vSwitch deployments.
+   - Support for travis-ci.org based continuous integration builds has been
+     added. Build failures are reported to build@openvswitch.org. See INSTALL.md
+     file for additional details.
+   - Support for the Rapid Spanning Tree Protocol (IEEE 802.1D-2004).
+     The implementation has been tested successfully against the Ixia Automated
+     Network Validation Library (ANVL).
+   - Stats are no longer updated on fake bond interface.
+   - Keep active bond slave selection across OVS restart.
+   - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker
+     containers. If and when there is a native integration of Open vSwitch
+     with Docker, the wrapper script will be retired.
+   - Added support for DPDK Tunneling. VXLAN and GRE are supported protocols.
+     This is generic tunneling mechanism for userspace datapath.
+   - Support for multicast snooping (IGMPv1 and IGMPv2)
+   - Support for Linux kernels up to 3.18.x
