2 ------------------------
4 - Added ability to match on IPv6 flow label through NXM.
5 - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
6 - Added ability to modify ECN bits in IPv4.
8 - New "fdb/flush" command to flush bridge's MAC learning table.
11 ------------------------
13 - Added an OpenFlow extension which allows the "output" action to accept
15 - Added an OpenFlow extension for flexible learning.
16 - Bumped number of NXM registers from four to five.
18 - New "version" command to determine version of running daemon.
19 - If no argument is provided for "cfm/show", displays detailed
20 information about all interfaces with CFM enabled.
21 - If no argument is provided for "lacp/show", displays detailed
22 information about all ports with LACP enabled.
24 - New "set-if" command to modify a datapath port's configuration.
26 - The software switch now supports 255 OpenFlow tables, instead
27 of just one. By default, only table 0 is consulted, but the
28 new NXAST_RESUBMIT_TABLE action can look up in additional
29 tables. Tables 128 and above are reserved for use by the
30 switch itself; please use only tables 0 through 127.
31 - Add support for 802.1D spanning tree (STP).
32 - Fragment handling extensions:
33 - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
34 fields are made available for matching in fragments with
36 - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
37 via "ip_frag" in ovs-ofctl).
38 - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
39 fragment handling policy.
40 - CAPWAP tunneling now supports an extension to transport a 64-key. By
41 default it remains compatible with the old version and other
42 standards-based implementations.
43 - Flow setups are now processed in a round-robin manner across ports
44 to prevent any single client from monopolizing the CPU and conducting
45 a denial of service attack.
46 - Added support for native VLAN tagging. A new "vlan_mode"
47 parameter can be set for "port". Possible values: "access",
48 "trunk", "native-tagged" and "native-untagged".
49 - test-openflowd has been removed. Please use ovs-vswitchd instead.
52 ------------------------
53 - New "ofproto" abstraction layer to ease porting to hardware
55 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.

61 - Support cooperative locking between callers.
63 - New "-s" option for "show" command prints packet and byte
64 counters for each port.
66 - New "--readd" option for "replace-flows".
68 - New "show" command to print an overview of configuration.
69 - New "comment" command to add remark that explains intentions.
70 - ovs-brcompatd has been rewritten to fix long-standing bugs.
71 - ovs-openflowd has been renamed test-openflowd and moved into the
72 tests directory. Its presence confused too many users. Please
73 use ovs-vswitchd instead.
74 - New ovs-benchmark utility to test flow setup performance.
75 - A new log level "off" has been added. Configuring a log facility
76 "off" prevents any messages from being logged to it. Previously,
77 "emer" was effectively "off" because no messages were ever logged at
78 level "emer". Now, errors that cause a process to exit are logged
80 - "configure" option --with-l26 has been renamed --with-linux, and
81 --with-l26-source has been renamed --with-linux-source. The old
82 names will be removed after the next release, so please update
84 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
85 datapath/linux-2.6/compat-2.6 directories.
87 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
88 Please use the extensible match extensions instead.
89 - Removed the Maintenance_Point and Monitor tables in an effort
90 to simplify 802.1ag configuration.

141 - New extension to set the QoS output queue without actually
142 sending to an output port.
143 - Open vSwitch now reports a single flow table, instead of
144 separate hash and wildcard tables. This better models the
145 current implementation.
146 - New experimental "note" action.
147 - New "ofproto/trace" ovs-appctl command and associated utilities
148 to ease debugging complex flow tables.
150 - Schema documentation now includes an entity-relationship diagram.
151 - The database is now garbage collected. In most tables,
152 unreferenced rows will be deleted automatically.
153 - Many tables now include statistics updated periodically by
154 ovs-vswitchd or ovsdb-server.
155 - Every table now has an "external-ids" column for use by OVS
