Post-v2.3.0
---------------------
+ - The MAC learning feature now includes per-port fairness to mitigate
+ MAC flooding attacks.
+ - New support for a "conjunctive match" OpenFlow extension, which
+ allows constructing OpenFlow matches of the form "field1 in
+ {a,b,c...} AND field2 in {d,e,f...}" and generalizations. For details,
+ see documentation for the "conjunction" action in ovs-ofctl(8).
- Add bash command-line completion support for ovs-appctl/ovs-dpctl/
ovs-ofctl/ovsdb-tool commands. Please check
utilities/ovs-command-compgen.INSTALL.md for how to use.

- The OVS database now reports controller rate limiting statistics.
- sflow now exports information about LACP-based bonds, port names, and
- OpenFlow port numbers.
+ OpenFlow port numbers, as well as datapath performance counters.
- ovs-dpctl functionality is now available for datapaths integrated
into ovs-vswitchd, via ovs-appctl. Some existing ovs-appctl
commands are now redundant and will be removed in a future
release. See ovs-vswitchd(8) for details.
- OpenFlow:
+ * IPv6 flow label and neighbor discovery fields are now modifiable.
* OpenFlow 1.5 (draft) extended registers are now supported.

* OpenFlow 1.5 (draft) Copy-Field action is now supported.
with Docker, the wrapper script will be retired.

- Compatibility with autoconf 2.63 (previously >=2.64)
v2.2.0 - Internal Release
* ovs-vswitchd now honors changes to the "ofport_request" column
in the Interface table by changing the port's OpenFlow port
number.
+ * The Open vSwitch software switch now supports OpenFlow groups.
- ovs-vswitchd.conf.db.5 man page will contain graphviz/dot
diagram only if graphviz package was installed at the build time.
- Support for Linux kernels up to 3.11
