OpenFlow 1.6 support in Open vSwitch 2.9

Hello mates,
Just a quick question. Does Open vSwitch 2.9 has full support of Openflow 1.6, or it is still missing some features. I have searched the documents, but I have found information on until OVS 2.8 in Open vSwitch official page.

Thank you in advance :hugs:
