+ - Add support for 802.1D spanning tree (STP).
+ - Fragment handling extensions:
+ - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
+ fields are made available for matching in fragments with
+ offset 0.
+ - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
+ via "ip_frag" in ovs-ofctl).
+ - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
+ fragment handling policy.
+ - CAPWAP tunneling now supports an extension to transport a 64-key. By
+ default it remains compatible with the old version and other
+ standards-based implementations.
+ - Flow setups are now processed in a round-robin manner across ports
+ to prevent any single client from monopolizing the CPU and conducting
+ a denial of service attack.
+ - Added support for native VLAN tagging. A new "vlan_mode"
+ parameter can be set for "port". Possible values: "access",
+ "trunk", "native-tagged" and "native-untagged".
+ - test-openflowd has been removed. Please use ovs-vswitchd instead.
