+ * New option "--color" to produce colorized output for some commands.
+ * New commands "dump-ipfix-bridge" and "dump-ipfix-flow" to dump bridge
+ IPFIX statistics and flow based IPFIX statistics.

+ * The mechanism for configuring DPDK has changed to use database
+ * Sensible defaults have been introduced for many of the required

+ * 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.
+ - 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.

+ tun_ipv6_src, tun_ipv6_dst fields.
+ * Added support for IPv6 tunnels to native tunneling.
+
+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
now supported.
* OpenFlow 1.4+ "importance" is now considered for flow eviction.
* OpenFlow 1.4+ OFPTC_EVICTION is now implemented.
+ * OpenFlow 1.4+ OFPTC_VACANCY_EVENTS is now implemented.
* OpenFlow 1.4+ OFPMP_TABLE_DESC is now implemented.
- - Support for matching/generating options as well as the OAM bit with
- Geneve tunnels.
+ * 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.
+ - 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.
-
-
-v2.4.0 - xx xxx xxxx
+ - Mark --syslog-target argument as deprecated. It will be removed in
+ the next OVS release.
+ - Added --user option to all daemons
+ - Add support for connection tracking through the new "ct" action
+ and "ct_state"/"ct_zone"/"ct_mark"/"ct_label" match fields. Only
+ available on Linux kernels with the connection tracking module loaded.
+ - Add experimental version of OVN. OVN, the Open Virtual Network, is a
+ 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
+
+v2.4.0 - 20 Aug 2015
---------------------
- Flow table modifications are now atomic, meaning that each packet
now sees a coherent version of the OpenFlow pipeline. For
