2 ------------------------
4 - Added support for querying, modifying, and deleting flows
5 based on flow cookie when using NXM.
6 - Added new NXM_PACKET_IN format.
8 - Added daemonization support to the monitor and snoop commands.
10 - The "find" command supports new set relational operators
11 {=}, {!=}, {<}, {>}, {<=}, and {>=}.
12 - ovsdb-tool now uses the typical database and schema installation
13 directories as defaults.
17 ------------------------
18 - New "VLAN splinters" feature to work around buggy device drivers
19 in old Linux versions. (This feature is deprecated. When
20 broken device drivers are no longer in widespread use, we will
21 delete this feature.) See ovs-vswitchd.conf.db(5) for more
24 - Added ability to match on IPv6 flow label through NXM.
25 - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
26 - Added ability to match on TTL in IPv4 and IPv6 through NXM.
27 - Added ability to modify ECN bits in IPv4.
28 - Added ability to modify TTL in IPv4.
30 - Don't require the "normal" action to use mirrors. Traffic will
31 now be properly mirrored for any flows, regardless of their
33 - Track packet and byte statistics sent on mirrors.
34 - The sFlow implementation can now usually infer the correct agent
35 device instead of having to be told explicitly.
37 - New "fdb/flush" command to flush bridge's MAC learning table.
39 - A new distributed testing tool that allows one to diagnose performance
40 and connectivity issues. This tool currently is not included in RH or
42 - RHEL packaging now supports integration with Red Hat network scripts.
44 - Post 1.4.*, OVS will be changing the default bond mode from balance-slb
45 to active-backup. SLB bonds carry significant risks with them
46 (documented vswitchd/INTERNALS) which we want to prevent unsuspecting
47 users from running into. Users are advised to update any scripts or
48 configuration which may be negatively impacted by explicitly setting
49 the bond mode which they want to use.
53 ------------------------
55 - Added an OpenFlow extension which allows the "output" action to accept
57 - Added an OpenFlow extension for flexible learning.
58 - Bumped number of NXM registers from four to five.
60 - New "version" command to determine version of running daemon.
61 - If no argument is provided for "cfm/show", displays detailed
62 information about all interfaces with CFM enabled.
63 - If no argument is provided for "lacp/show", displays detailed
64 information about all ports with LACP enabled.
66 - New "set-if" command to modify a datapath port's configuration.
68 - The software switch now supports 255 OpenFlow tables, instead
69 of just one. By default, only table 0 is consulted, but the
70 new NXAST_RESUBMIT_TABLE action can look up in additional
71 tables. Tables 128 and above are reserved for use by the
72 switch itself; please use only tables 0 through 127.
73 - Add support for 802.1D spanning tree (STP).
74 - Fragment handling extensions:
75 - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
76 fields are made available for matching in fragments with
78 - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
79 via "ip_frag" in ovs-ofctl).
80 - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
81 fragment handling policy.
82 - CAPWAP tunneling now supports an extension to transport a 64-bit key.
83 By default it remains compatible with the old version and other
84 standards-based implementations.
85 - Flow setups are now processed in a round-robin manner across ports
86 to prevent any single client from monopolizing the CPU and conducting
87 a denial of service attack.
88 - Added support for native VLAN tagging. A new "vlan_mode"
89 parameter can be set for "port". Possible values: "access",
90 "trunk", "native-tagged" and "native-untagged".
91 - test-openflowd has been removed. Please use ovs-vswitchd instead.
94 ------------------------
95 - New "ofproto" abstraction layer to ease porting to hardware
97 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
98 - Datapath support for Linux kernels up to 3.0.

102 - Implement table unique constraints.
103 - Support cooperative locking between callers.
105 - New "-s" option for "show" command prints packet and byte
106 counters for each port.
108 - New "--readd" option for "replace-flows".
110 - New "show" command to print an overview of configuration.
111 - New "comment" command to add remark that explains intentions.
112 - ovs-brcompatd has been rewritten to fix long-standing bugs.
113 - ovs-openflowd has been renamed test-openflowd and moved into the
114 tests directory. Its presence confused too many users. Please
115 use ovs-vswitchd instead.
116 - New ovs-benchmark utility to test flow setup performance.
117 - A new log level "off" has been added. Configuring a log facility
118 "off" prevents any messages from being logged to it. Previously,
119 "emer" was effectively "off" because no messages were ever logged at
120 level "emer". Now, errors that cause a process to exit are logged
122 - "configure" option --with-l26 has been renamed --with-linux, and
123 --with-l26-source has been renamed --with-linux-source. The old
124 names will be removed after the next release, so please update
126 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
127 datapath/linux-2.6/compat-2.6 directories.
129 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
130 Please use the extensible match extensions instead.
131 - Removed the Maintenance_Point and Monitor tables in an effort
132 to simplify 802.1ag configuration.

179 - New "register" extension for use in matching and actions, via NXM.
180 - New "multipath" experimental action extension.

182 - New extension for OpenFlow vendor error codes.
183 - New extension to set the QoS output queue without actually
184 sending to an output port.
185 - Open vSwitch now reports a single flow table, instead of
186 separate hash and wildcard tables. This better models the
187 current implementation.
188 - New experimental "note" action.
189 - New "ofproto/trace" ovs-appctl command and associated utilities
190 to ease debugging complex flow tables.
192 - Schema documentation now includes an entity-relationship diagram.
193 - The database is now garbage collected. In most tables,
194 unreferenced rows will be deleted automatically.
195 - Many tables now include statistics updated periodically by
196 ovs-vswitchd or ovsdb-server.
197 - Every table now has an "external-ids" column for use by OVS
199 - There is no default controller anymore. Each bridge must have its

201 - The "fail-mode" is now a property of a Bridge instead of a Controller.
202 - New versioning and checksum features.

211 - Dropped "ovs-ofctl status" and the OpenFlow extension that it used.
212 Statistics reporting in the database is a rough equivalent.
213 - Dropped the "corekeeper" package (now separate, at
214 http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
