[OpenFlow] What's new with OpenFlow v1.3

Big Switch Netwoks give a brief introduction about the new with OpenFlow v1.2 as the following URL:
What is new with OpenFlow v1.2?

I also paste the summary from that and aslo add a few comments by my point of view.

OpenFlow 1.0:  Dec 2010

• First “official” release
• Basic QoS – minimum bandwidth guarantees
• Flow Cookies – store metadata in flow table
• Broadly implemented

OpenFlow 1.1:  Feb 2011

• Multiple tables
• Group table – ECMP, fast failover, Multicast
• MPLS/QinQ support
• Few implementaKon, less deployment

Openflow 1.2:   Dec 2011

• More flexible packet matching
• Makes specification easier to extend
• Allows third-parties to define their own match types
• Basic IPv6 support
•  Match on src/dst IPv6 address + flow label
•  No support for matching IPv6 extensions
• Improved controller failover mechanism
• Enables “active-­active” fast-failover
• It needs switch to co-operate with controller.
• v1.2 is inherent from most of the features from v1.1 
• v1.1 and v1.2 are not compatible with v1.0
• The flow table is different from v1.0. In v1.2, it has "Match Fields", "Counters", and "Instructions" instead of "Actions"

Openflow 1.3 Apr 2012:

• introduces per flow meters, IPv6 extension header 
• handling, flexible table miss support, enhanced/refactored 
• capability negotiation, multipart requests, MPLS BoS matching,
