-Post-v2.3.0
+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
+ have Python 2.4) requires first installing Python 2.7.
+ - OpenFlow:
+ * Group chaining (where one OpenFlow group triggers another) is
+ 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.
+ * 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.
+ - 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
+ - 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
+ - SELinux:
+ * Introduced SELinux policy package.
+
+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
openvswitch.ko but built and loaded automatically as individual kernel
modules (vport-*.ko).
- Support for STT tunneling.
+ - ovs-sim: New developer tool for simulating multiple OVS instances.
+ See ovs-sim(1) for more information.
+ - Support to configure method (--syslog-method argument) that determines
+ how daemons will talk with syslog.
+ - Support for "ovs-appctl vlog/list-pattern" command that lets to query
+ logging message format for each destination.
