2 ------------------------
4 - Added an OpenFlow extension which allows the "output" action to accept
6 - Added an OpenFlow extension for flexible learning.
8 - New "version" command to determine version of running daemon
10 - The software switch now supports 255 OpenFlow tables, instead
11 of just one. By default, only table 0 is consulted, but the
12 new NXAST_RESUBMIT_TABLE action can look up in additional
13 tables. Tables 128 and above are reserved for use by the
14 switch itself; please use only tables 0 through 127.
15 - CAPWAP tunneling now supports an extension to transport a 64-key. By
16 default it remains compatible with the old version and other
17 standards-based implementations.
18 - Flow setups are now processed in a round-robin manner across ports
19 to prevent any single client from monopolizing the CPU and conducting
20 a denial of service attack.
21 - Added support for native VLAN tagging. A new "vlan_mode"
22 parameter can be set for "port". Possible values: "access",
23 "trunk", "native-tagged" and "native-untagged".
26 ------------------------
27 - New "ofproto" abstraction layer to ease porting to hardware
29 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
30 - Datapath support for Linux kernels up to 3.0.
32 - New "bundle" and "bundle_load" action extensions.
34 - Implement table unique constraints.
35 - Support cooperative locking between callers.
37 - New "-s" option for "show" command prints packet and byte
38 counters for each port.
40 - New "--readd" option for "replace-flows".
42 - New "show" command to print an overview of configuration.
43 - New "comment" command to add remark that explains intentions.
44 - ovs-brcompatd has been rewritten to fix long-standing bugs.
45 - ovs-openflowd has been renamed test-openflowd and moved into the
46 tests directory. Its presence confused too many users. Please
47 use ovs-vswitchd instead.
48 - New ovs-benchmark utility to test flow setup performance.
49 - A new log level "off" has been added. Configuring a log facility
50 "off" prevents any messages from being logged to it. Previously,
51 "emer" was effectively "off" because no messages were ever logged at
52 level "emer". Now, errors that cause a process to exit are logged
54 - "configure" option --with-l26 has been renamed --with-linux, and
55 --with-l26-source has been renamed --with-linux-source. The old
56 names will be removed after the next release, so please update
58 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
59 datapath/linux-2.6/compat-2.6 directories.
61 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
62 Please use the extensible match extensions instead.
63 - Removed the Maintenance_Point and Monitor tables in an effort
64 to simplify 802.1ag configuration.
65 - Performance and scalability improvements
69 ------------------------
70 - Ability to define policies over IPv6
73 - Support for extensible match extensions to OpenFlow
75 - Support for HFSC qdisc.
76 - Queue used by in-band control can now be configured.
78 - Kernel<->userspace interface has been reworked and should be
79 close to a stable ABI now.
80 - "Port group" concept has been dropped.
81 - GRE over IPSEC tunnels
83 - New active backup bonding mode.
84 - New L4 hashing support when LACP is enabled.
85 - Source MAC hash now includes VLAN field also.
87 - Greatly improved handling of large flow tables
89 - "show" command now prints full vport configuration.
90 - "dump-groups" command removed since kernel support for
91 port groups was dropped.
93 - New commands for working with the new Managers table.
94 - "list" command enhanced with new formatting options and --columns
96 - "get" command now accepts new --id option.
99 - New "queue-stats" command for printing queue stats.
100 - New commands "replace-flows" and "diff-flows".
101 - Commands to add and remove flows can now read from files.
102 - New --flow-format option to enable or disable NXM.
103 - New --more option to increase OpenFlow message verbosity.
104 - Removed "tun-cookie" command, which is no longer useful.
105 - ovs-controller enhancements for testing various features.
106 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
107 bugs. New ovs-vlan-bug-workaround command for enabling and
108 disabling a workaround for these driver bugs.
110 - "Resubmit" actions now update flow statistics.
111 - New "register" extension for use in matching and actions, via NXM.
112 - New "multipath" experimental action extension.
113 - New support for matching multicast Ethernet frames, via NXM.
114 - New extension for OpenFlow vendor error codes.
115 - New extension to set the QoS output queue without actually
116 sending to an output port.
117 - Open vSwitch now reports a single flow table, instead of
118 separate hash and wildcard tables. This better models the
119 current implementation.
120 - New experimental "note" action.
121 - New "ofproto/trace" ovs-appctl command and associated utilities
122 to ease debugging complex flow tables.
124 - Schema documentation now includes an entity-relationship diagram.
125 - The database is now garbage collected. In most tables,
126 unreferenced rows will be deleted automatically.
127 - Many tables now include statistics updated periodically by
128 ovs-vswitchd or ovsdb-server.
129 - Every table now has an "external-ids" column for use by OVS
131 - There is no default controller anymore. Each bridge must have its
132 controller individually specified.
133 - The "fail-mode" is now a property of a Bridge instead of a Controller.
134 - New versioning and checksum features.
135 - New Managers table and manager_options column in Open_vSwitch table
136 for specifying managers. The old "managers" column in the
137 Open_vSwitch table has been removed.

140 - Dropped support for XenServer pre-5.6.100.
141 - Dropped support for Linux pre-2.6.18.
142 - Dropped controller discovery support.
143 - Dropped "ovs-ofctl status" and the OpenFlow extension that it used.
144 Statistics reporting in the database is a rough equivalent.
145 - Dropped the "corekeeper" package (now separate, at
146 http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
