-Post-v2.3.0
+Post-v2.5.0
+---------------------
+
+
+v2.5.0 - xx xxx xxxx
+---------------------
+ - 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.
+
+
+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
with Docker, the wrapper script will be retired.
- Added support for DPDK Tunneling. VXLAN, GRE, and Geneve are supported
protocols. This is generic tunneling mechanism for userspace datapath.
- - Support for multicast snooping (IGMPv1 and IGMPv2)
+ - Support for multicast snooping (IGMPv1, IGMPv2 and IGMPv3)
- Support for Linux kernels up to 4.0.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
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.
