+v1.4.0 - 30 Jan 2012
+------------------------
+ - Compatible with Open vSwitch kernel module included in Linux 3.3.
+ - New "VLAN splinters" feature to work around buggy device drivers
+ in old Linux versions. (This feature is deprecated. When
+ broken device drivers are no longer in widespread use, we will
+ delete this feature.) See ovs-vswitchd.conf.db(5) for more
+ information.
+ - OpenFlow:
+ - Added ability to match on IPv6 flow label through NXM.
+ - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
+ - Added ability to match on TTL in IPv4 and IPv6 through NXM.
+ - Added ability to modify ECN bits in IPv4.
+ - Added ability to modify TTL in IPv4.
+ - ovs-vswitchd:
+ - Don't require the "normal" action to use mirrors. Traffic will
+ now be properly mirrored for any flows, regardless of their
+ actions.
+ - Track packet and byte statistics sent on mirrors.
+ - The sFlow implementation can now usually infer the correct agent
+ device instead of having to be told explicitly.
