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.
23 ------------------------
24 - New "ofproto" abstraction layer to ease porting to hardware
26 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
27 - Datapath support for Linux kernels up to 3.0.
29 - New "bundle" and "bundle_load" action extensions.
31 - Implement table unique constraints.
32 - Support cooperative locking between callers.
34 - New "-s" option for "show" command prints packet and byte
35 counters for each port.
37 - New "--readd" option for "replace-flows".
39 - New "show" command to print an overview of configuration.
40 - New "comment" command to add remark that explains intentions.
41 - ovs-brcompatd has been rewritten to fix long-standing bugs.
42 - ovs-openflowd has been renamed test-openflowd and moved into the
43 tests directory. Its presence confused too many users. Please
44 use ovs-vswitchd instead.
45 - New ovs-benchmark utility to test flow setup performance.
46 - A new log level "off" has been added. Configuring a log facility
47 "off" prevents any messages from being logged to it. Previously,
48 "emer" was effectively "off" because no messages were ever logged at
49 level "emer". Now, errors that cause a process to exit are logged
51 - "configure" option --with-l26 has been renamed --with-linux, and
52 --with-l26-source has been renamed --with-linux-source. The old
53 names will be removed after the next release, so please update
55 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
56 datapath/linux-2.6/compat-2.6 directories.
58 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
59 Please use the extensible match extensions instead.
60 - Removed the Maintenance_Point and Monitor tables in an effort
61 to simplify 802.1ag configuration.
62 - Performance and scalability improvements
66 ------------------------
67 - Ability to define policies over IPv6
70 - Support for extensible match extensions to OpenFlow
72 - Support for HFSC qdisc.
73 - Queue used by in-band control can now be configured.
75 - Kernel<->userspace interface has been reworked and should be
76 close to a stable ABI now.
77 - "Port group" concept has been dropped.
78 - GRE over IPSEC tunnels
80 - New active backup bonding mode.
81 - New L4 hashing support when LACP is enabled.
82 - Source MAC hash now includes VLAN field also.
84 - Greatly improved handling of large flow tables
86 - "show" command now prints full vport configuration.
87 - "dump-groups" command removed since kernel support for
88 port groups was dropped.
90 - New commands for working with the new Managers table.
91 - "list" command enhanced with new formatting options and --columns
93 - "get" command now accepts new --id option.
96 - New "queue-stats" command for printing queue stats.
97 - New commands "replace-flows" and "diff-flows".
98 - Commands to add and remove flows can now read from files.
99 - New --flow-format option to enable or disable NXM.
100 - New --more option to increase OpenFlow message verbosity.
101 - Removed "tun-cookie" command, which is no longer useful.
102 - ovs-controller enhancements for testing various features.
103 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
104 bugs. New ovs-vlan-bug-workaround command for enabling and
105 disabling a workaround for these driver bugs.
107 - "Resubmit" actions now update flow statistics.
108 - New "register" extension for use in matching and actions, via NXM.
109 - New "multipath" experimental action extension.

111 - New extension for OpenFlow vendor error codes.
112 - New extension to set the QoS output queue without actually
113 sending to an output port.
114 - Open vSwitch now reports a single flow table, instead of
115 separate hash and wildcard tables. This better models the
116 current implementation.
117 - New experimental "note" action.
118 - New "ofproto/trace" ovs-appctl command and associated utilities
119 to ease debugging complex flow tables.
121 - Schema documentation now includes an entity-relationship diagram.
122 - The database is now garbage collected. In most tables,
123 unreferenced rows will be deleted automatically.
124 - Many tables now include statistics updated periodically by
125 ovs-vswitchd or ovsdb-server.
126 - Every table now has an "external-ids" column for use by OVS
128 - There is no default controller anymore. Each bridge must have its
129 controller individually specified.
130 - The "fail-mode" is now a property of a Bridge instead of a Controller.
131 - New versioning and checksum features.
132 - New Managers table and manager_options column in Open_vSwitch table
133 for specifying managers. The old "managers" column in the
134 Open_vSwitch table has been removed.

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