+ - ovsdb-server:
+ * New "monitor_cond" "monitor_cond_update" and "update2" extensions to
+ RFC 7047.
+ - OpenFlow:

+ * New output option, output(port=N,max_len=M), to allow truncating a
+ packet to size M bytes when outputting to port N.
+ * New command OFPGC_ADD_OR_MOD for OFPT_GROUP_MOD message that adds a
+ new group or modifies an existing groups
+ - Improved OpenFlow version compatibility for actions:
+ * New OpenFlow extension to support the "group" action in OpenFlow 1.0.
+ * OpenFlow 1.0 "enqueue" action now properly translated to OpenFlow 1.1+.
+ * OpenFlow 1.1 "mod_nw_ecn" and OpenFlow 1.1+ "mod_nw_ttl" actions now

+ * New "sampling_port" option for "sample" action to allow sampling
+ ingress and egress tunnel metadata with IPFIX.
+ * New ovs-ofctl commands "dump-ipfix-bridge" and "dump-ipfix-flow" to
+ dump bridge IPFIX statistics and flow based IPFIX statistics.
+ * New setting other-config:virtual_obs_id to add an arbitrary string
+ to IPFIX records.
+ - Linux:
+ * New QoS type "linux-noop" that prevents Open vSwitch from trying to
+ manage QoS for a given port (useful when other software manages QoS).
+ - DPDK:
+ * New option "n_rxq" for PMD interfaces.
+ Old 'other_config:n-dpdk-rxqs' is no longer supported.
+ Not supported by vHost interfaces. For them number of rx and tx queues
+ is applied from connected virtio device.
+ * New appctl command 'dpif-netdev/pmd-rxq-show' to check the port/rxq
+ assignment.
+ * Type of log messages from PMD threads changed from INFO to DBG.
+ * QoS functionality with sample egress-policer implementation.
+ * The mechanism for configuring DPDK has changed to use database
+ * Sensible defaults have been introduced for many of the required
+ configuration options
+ * DB entries have been added for many of the DPDK EAL command line
+ arguments. Additional arguments can be passed via the dpdk-extra
+ entry.
+ * Add ingress policing functionality.
+ * PMD threads servicing vHost User ports can now come from the NUMA
+ node that device memory is located on if CONFIG_RTE_LIBRTE_VHOST_NUMA
+ is enabled in DPDK.
+ - Increase number of registers to 16.
+ - ovs-benchmark: This utility has been removed due to lack of use and
+ bitrot.
+ - ovs-appctl:
+ * New "vlog/close" command.
+ - ovs-ctl:
+ * Added the ability to selectively start the forwarding and database
+ functions (ovs-vswitchd and ovsdb-server, respectively).
+ - ovsdb-server:
+ * Remove max number of sessions limit, to enable connection scaling
+ testing.
+ - python:
+ * Added support for Python 3.4+ in addition to existing support
+ for 2.7+.
+ - SELinux:
+ * Introduced SELinux policy package.
+ - Datapath Linux kernel compatibility.
+ * Dropped support for kernel older than 3.10.
+ * Removed VLAN splinters feature.
+ * Support for truncate action.
+ * Datapath supports kernel upto 4.6.
+ - Tunnels:
+ * Flow based tunnel match and action can be used for IPv6 address using
+ tun_ipv6_src, tun_ipv6_dst fields.
+ * Added support for IPv6 tunnels, for details checkout FAQ.
+ - A wrapper script, 'ovs-tcpdump', to easily port-mirror an OVS port and
+ watch with tcpdump
+ - Introduce --no-self-confinement flag that allows daemons to work with
+ sockets outside their run directory.
+ - ovs-pki: Changed message digest algorithm from SHA-1 to SHA-512 because
+ SHA-1 is no longer secure and some operating systems have started to
+ disable it in OpenSSL.

+v2.5.0 - 26 Feb 2016
---------------------
- Dropped support for Python older than version 2.7. As a consequence,
using Open vSwitch 2.5 or later on XenServer 6.5 or earlier (which
* OpenFlow 1.4+ OFPTC_VACANCY_EVENTS is now implemented.
* OpenFlow 1.4+ OFPMP_TABLE_DESC is now implemented.
* Allow modifying the ICMPv4/ICMPv6 type and code fields.
+ * OpenFlow 1.4+ OFPT_SET_ASYNC_CONFIG and OFPT_GET_ASYNC_CONFIG are
+ now implemented.
- ovs-ofctl:
* New "out_group" keyword for OpenFlow 1.1+ matching on output group.
- - Support for matching/generating options as well as the OAM bit with
- Geneve tunnels.
+ - Tunnels:
+ * Geneve tunnels can now match and set options and the OAM bit.
+ * The nonstandard GRE64 tunnel extension has been dropped.
- Support Multicast Listener Discovery (MLDv1 and MLDv2).
- Add 'symmetric_l3l4' and 'symmetric_l3l4+udp' hash functions.
- sFlow agent now reports tunnel and MPLS structures.
- - Added OpenFlow 1.4+ OFPT_SET_ASYNC_CONFIG and OFPT_GET_ASYNC_CONFIG
- that allows controllers to have more precise control over OpenFlow1.4
- asynchronous messages.
- New 'check-system-userspace', 'check-kmod' and 'check-kernel' Makefile
targets to run a new system testsuite. These tests can be run inside
a Vagrant box. See INSTALL.md for details
- - Dropped support for GRE64 tunnel.
- Mark --syslog-target argument as deprecated. It will be removed in
the next OVS release.
- Added --user option to all daemons
system to support virtual network abstraction. OVN complements the
existing capabilities of OVS to add native support for virtual network
abstractions, such as virtual L2 and L3 overlays and security groups.
-
+ - RHEL packaging:
+ * DPDK ports may now be created via network scripts (see README.RHEL).
+ - DPDK:
+ * Requires DPDK 2.2
+ * Added multiqueue support to vhost-user
+ * Note: QEMU 2.5+ required for multiqueue support
