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. + - Basic support for the Geneve tunneling protocol. It is not yet + possible to generate or match options. This is planned for a future + 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. + - 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. + * The OpenFlow 1.5 (draft) actset_output field is now supported. + * OpenFlow 1.5 (draft) Copy-Field action is now supported. + * OpenFlow 1.5 (draft) 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. + - 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) + + +v2.3.0 - 14 Aug 2014 +--------------------- + - 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. + - Compatibility with autoconf 2.63 (previously >=2.64) + +v2.2.0 - Internal Release +--------------------- + - Internal ports are no longer brought up by default, because it + should be an administrator task to bring up devices as they are + configured properly. + - ovs-vsctl now reports when ovs-vswitchd fails to create a new port or + bridge. + - Port creation and configuration errors are now stored in a new error + column of the Interface table and included in 'ovs-vsctl show'. + - 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.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' + instead. + - Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses + tunnel API for GRE and VXLAN. + - Added DPDK support. + - Added support for custom vlog patterns in Python + + +v2.1.0 - 19 Mar 2014 --------------------- - - Address prefix tracking support for flow tables.
