+ - Tunnel Path MTU Discovery default value was set to 'disabled'. This
+ feature is deprecated and will be removed soon.
+ - ovsdb-server now enforces the immutability of immutable columns. This
+ was not enforced in earlier versions due to an oversight.
+ - New support for a nonstandard form of GRE that supports a 64-bit key.
+ - The ofproto library is now responsible for assigning OpenFlow port
+ numbers. An ofproto implementation should assign them when
+ port_construct() is called.
+ - All dpif-based bridges of a particular type share a common
+ datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl
+ commands will now return information on that shared datapath. To
+ get the equivalent bridge-specific information, use the new
+ "ovs-appctl dpif/*" commands.
+ - Tunnel header caching removed.
+ - The following features are now deprecated. They will be removed no
+ earlier than February 2013. Please email dev@openvswitch.org with
+ concerns.
+ - Stable bond mode.
+ - The autopath action.
+ - Interface type "null".
+ - Numeric values for reserved ports (see "ovs-ofctl" note above).
+ - Tunnel Path MTU Discovery.
+ - CAPWAP tunnel support.
+ - The data in the RARP packets can now be matched in the same way as the
+ data in ARP packets.
