Post-v2.3.0
---------------------
+ - Added support for SFQ, FQ_CoDel and CoDel qdiscs.
+ - Add bash command-line completion support for ovs-vsctl Please check
+ utilities/ovs-command-compgen.INSTALL.md for how to use.
+ - 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 "learn" action supports a new flag "delete_learned" that causes
the learned flows to be deleted when the flow with the "learn" action
is deleted.
release. The protocol is documented at
http://tools.ietf.org/html/draft-gross-geneve-00
- The OVS database now reports controller rate limiting statistics.
+ - sflow now exports information about LACP-based bonds, port names, and
+ 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:
- * OpenFlow 1.5 (draft) extended registers are now supported.
-
-
-v2.3.0 - xx xxx xxxx
+ * IPv6 flow label and neighbor discovery fields are now modifiable.
+ * OpenFlow 1.5 extended registers are now supported.
+ * The OpenFlow 1.5 actset_output field is now supported.
+ * OpenFlow 1.5 Copy-Field action is now supported.
+ * OpenFlow 1.5 masked Set-Field action is now supported.
+ * OpenFlow 1.3+ table features requests are now supported (read-only).
+ * Nicira extension "move" actions may now be included in action sets.
+ * "resubmit" actions may now be included in action sets. The resubmit
+ is executed last, and only if the action set has no "output" or "group"
+ action.
+ * OpenFlow 1.4+ flow "importance" is now maintained in the flow table.
+ * A new Netronome extension to OpenFlow 1.5+ allows control over the
+ fields hashed for OpenFlow select groups. See "selection_method" and
+ related options in ovs-ofctl(8) for details.
+ - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because
+ MD5 is no longer secure and some operating systems have started to disable
+ it in OpenSSL.
+ - ovsdb-server: New OVSDB protocol extension allows inequality tests on
+ "optional scalar" columns. See ovsdb-server(1) for details.
+ - ovs-vsctl now permits immutable columns in a new row to be modified in
+ the same transaction that creates the row.
+ - test-controller has been renamed ovs-testcontroller at request of users
+ who find it useful for testing basic OpenFlow setups. It is still not
+ a necessary or desirable part of most Open vSwitch deployments.
+ - Support for travis-ci.org based continuous integration builds has been
+ added. Build failures are reported to build@openvswitch.org. See INSTALL.md
+ file for additional details.
+ - Support for the Rapid Spanning Tree Protocol (IEEE 802.1D-2004).
+ The implementation has been tested successfully against the Ixia Automated
+ Network Validation Library (ANVL).
+ - Stats are no longer updated on fake bond interface.
+ - Keep active bond slave selection across OVS restart.
+ - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker
+ containers. If and when there is a native integration of Open vSwitch
+ with Docker, the wrapper script will be retired.
+ - Added support for DPDK Tunneling. VXLAN and GRE are supported protocols.
+ This is generic tunneling mechanism for userspace datapath.
+ - Support for multicast snooping (IGMPv1 and IGMPv2)
+ - Support for Linux kernels up to 3.19.x
+ - The documentation now use the term 'destination' to mean one of syslog,
+ console or file for vlog logging instead of the previously used term
+ 'facility'.
+ - Support for VXLAN Group Policy extension
+ - Initial support for the IETF Auto-Attach SPBM draft standard. This
+ contains rudimentary support for the LLDP protocol as needed for
+ Auto-Attach.
+ - The default OpenFlow and OVSDB ports are now the IANA-assigned
+ numbers. OpenFlow is 6653 and OVSDB is 6640.
+ - Support for DPDK vHost.
+ - Support for outer UDP checksums in Geneve and VXLAN.

+v2.3.0 - 14 Aug 2014
---------------------
- OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in
ovs-vswitchd.
packets with the larger number of masks, but when paired with an
older kernel module, some workloads may perform worse with the
new userspace.
- - Support for multicast snooping (IGMPv1 and IGMPv2)
- Compatibility with autoconf 2.63 (previously >=2.64)
v2.2.0 - Internal Release
- The "ovsdbmonitor" graphical tool has been removed, because it was
poorly maintained and not widely used.
- New "check-ryu" Makefile target for running Ryu tests for OpenFlow
- controllers against Open vSwitch. See INSTALL for details.
+ controllers against Open vSwitch. See INSTALL.md for details.
- Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows.
- Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its
log file (it will terminate instead). Please use 'ovs-appctl vlog/reopen'
* 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
