2 ------------------------
4 - Added an OpenFlow extension which allows the "output" action to accept
6 - Added an OpenFlow extension for flexible learning.
7 - Bumped number of NXM registers from four to five.
9 - New "version" command to determine version of running daemon.
10 - If no argument is provided for "cfm/show", displays detailed
11 information about all interfaces with CFM enabled.
12 - If no argument is provided for "lacp/show", displays detailed
13 information about all ports with LACP enabled.
15 - New "set-if" command to modify a datapath port's configuration.
17 - The software switch now supports 255 OpenFlow tables, instead
18 of just one. By default, only table 0 is consulted, but the
19 new NXAST_RESUBMIT_TABLE action can look up in additional
20 tables. Tables 128 and above are reserved for use by the
21 switch itself; please use only tables 0 through 127.
22 - Add support for 802.1D spanning tree (STP).
23 - Fragment handling extensions:
24 - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
25 fields are made available for matching in fragments with
27 - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
28 via "ip_frag" in ovs-ofctl).
29 - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
30 fragment handling policy.
31 - CAPWAP tunneling now supports an extension to transport a 64-key. By
32 default it remains compatible with the old version and other
33 standards-based implementations.
34 - Flow setups are now processed in a round-robin manner across ports
35 to prevent any single client from monopolizing the CPU and conducting
36 a denial of service attack.
37 - Added support for native VLAN tagging. A new "vlan_mode"
38 parameter can be set for "port". Possible values: "access",
39 "trunk", "native-tagged" and "native-untagged".
40 - test-openflowd has been removed. Please use ovs-vswitchd instead.
43 ------------------------
44 - New "ofproto" abstraction layer to ease porting to hardware
46 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
47 - Datapath support for Linux kernels up to 3.0.
49 - New "bundle" and "bundle_load" action extensions.
51 - Implement table unique constraints.
52 - Support cooperative locking between callers.
54 - New "-s" option for "show" command prints packet and byte
55 counters for each port.
57 - New "--readd" option for "replace-flows".
59 - New "show" command to print an overview of configuration.
60 - New "comment" command to add remark that explains intentions.
61 - ovs-brcompatd has been rewritten to fix long-standing bugs.
62 - ovs-openflowd has been renamed test-openflowd and moved into the
63 tests directory. Its presence confused too many users. Please
64 use ovs-vswitchd instead.
65 - New ovs-benchmark utility to test flow setup performance.
66 - A new log level "off" has been added. Configuring a log facility
67 "off" prevents any messages from being logged to it. Previously,
68 "emer" was effectively "off" because no messages were ever logged at
69 level "emer". Now, errors that cause a process to exit are logged
71 - "configure" option --with-l26 has been renamed --with-linux, and
72 --with-l26-source has been renamed --with-linux-source. The old
73 names will be removed after the next release, so please update
75 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
76 datapath/linux-2.6/compat-2.6 directories.
78 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
79 Please use the extensible match extensions instead.
80 - Removed the Maintenance_Point and Monitor tables in an effort
81 to simplify 802.1ag configuration.

101 - New L4 hashing support when LACP is enabled.
102 - Source MAC hash now includes VLAN field also.
104 - Greatly improved handling of large flow tables
106 - "show" command now prints full vport configuration.
107 - "dump-groups" command removed since kernel support for
108 port groups was dropped.
110 - New commands for working with the new Managers table.
111 - "list" command enhanced with new formatting options and --columns
113 - "get" command now accepts new --id option.
114 - New "find" command.
116 - New "queue-stats" command for printing queue stats.

122 - ovs-controller enhancements for testing various features.
123 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
124 bugs. New ovs-vlan-bug-workaround command for enabling and
125 disabling a workaround for these driver bugs.
127 - "Resubmit" actions now update flow statistics.
128 - New "register" extension for use in matching and actions, via NXM.
129 - New "multipath" experimental action extension.

131 - New extension for OpenFlow vendor error codes.
132 - New extension to set the QoS output queue without actually
133 sending to an output port.
134 - Open vSwitch now reports a single flow table, instead of
135 separate hash and wildcard tables. This better models the
136 current implementation.
137 - New experimental "note" action.
138 - New "ofproto/trace" ovs-appctl command and associated utilities
139 to ease debugging complex flow tables.
141 - Schema documentation now includes an entity-relationship diagram.
142 - The database is now garbage collected. In most tables,
143 unreferenced rows will be deleted automatically.
144 - Many tables now include statistics updated periodically by
145 ovs-vswitchd or ovsdb-server.
146 - Every table now has an "external-ids" column for use by OVS
148 - There is no default controller anymore. Each bridge must have its
149 controller individually specified.

151 - New versioning and checksum features.

161 Statistics reporting in the database is a rough equivalent.
162 - Dropped the "corekeeper" package (now separate, at
163 http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
