Post-v2.2.0
---------------------
-
+ - OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in
+ ovs-vswitchd.
+ - Linux kernel datapath now has an exact match cache optimizing the
+ flow matching process.
+ - Datapath flows now have partially wildcarded tranport port field
+ matches. This reduces userspace upcalls, but increases the
+ number of different masks in the datapath. The kernel datapath
+ exact match cache removes the overhead of matching the incoming
+ packets with the larger number of masks, but when paired with an
+ older kernel module, some workloads may perform worse with the
+ new userspace.
