2 ------------------------
3 - New "ofproto" abstraction layer to ease porting to hardware
5 - Packaging for Red Hat Enterprise Linux 5.6 and 6.0.
6 - Datapath support for Linux kernels up to 3.0.
8 - New "bundle" and "bundle_load" action extensions.
10 - Implement table unique constraints.
11 - Support cooperative locking between callers.
13 - New "-s" option for "show" command prints packet and byte
14 counters for each port.
16 - New "--readd" option for "replace-flows".
18 - New "show" command to print an overview of configuration.
19 - New "comment" command to add remark that explains intentions.
20 - ovs-brcompatd has been rewritten to fix long-standing bugs.
21 - ovs-openflowd has been renamed test-openflowd and moved into the
22 tests directory. Its presence confused too many users. Please
23 use ovs-vswitchd instead.
24 - New ovs-benchmark utility to test flow setup performance.
25 - A new log level "off" has been added. Configuring a log facility
26 "off" prevents any messages from being logged to it. Previously,
27 "emer" was effectively "off" because no messages were ever logged at
28 level "emer". Now, errors that cause a process to exit are logged
30 - "configure" option --with-l26 has been renamed --with-linux, and
31 --with-l26-source has been renamed --with-linux-source. The old
32 names will be removed after the next release, so please update
34 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
35 datapath/linux-2.6/compat-2.6 directories.
37 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
38 Please use the extensible match extensions instead.
39 - Removed the Maintenance_Point and Monitor tables in an effort
40 to simplify 802.1ag configuration.
41 - Performance and scalability improvements

46 - Ability to define policies over IPv6
49 - Support for extensible match extensions to OpenFlow

55 close to a stable ABI now.
56 - "Port group" concept has been dropped.
57 - GRE over IPSEC tunnels
59 - New active backup bonding mode.

61 - Source MAC hash now includes VLAN field also.
63 - Greatly improved handling of large flow tables
65 - "show" command now prints full vport configuration.
66 - "dump-groups" command removed since kernel support for
67 port groups was dropped.
69 - New commands for working with the new Managers table.
70 - "list" command enhanced with new formatting options and --columns
72 - "get" command now accepts new --id option.
75 - New "queue-stats" command for printing queue stats.
76 - New commands "replace-flows" and "diff-flows".
77 - Commands to add and remove flows can now read from files.
78 - New --flow-format option to enable or disable NXM.
79 - New --more option to increase OpenFlow message verbosity.
80 - Removed "tun-cookie" command, which is no longer useful.
81 - ovs-controller enhancements for testing various features.
82 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
83 bugs. New ovs-vlan-bug-workaround command for enabling and
84 disabling a workaround for these driver bugs.
86 - "Resubmit" actions now update flow statistics.
87 - New "register" extension for use in matching and actions, via NXM.
88 - New "multipath" experimental action extension.

90 - New extension for OpenFlow vendor error codes.
91 - New extension to set the QoS output queue without actually
92 sending to an output port.
93 - Open vSwitch now reports a single flow table, instead of
94 separate hash and wildcard tables. This better models the
95 current implementation.
96 - New experimental "note" action.
97 - New "ofproto/trace" ovs-appctl command and associated utilities
98 to ease debugging complex flow tables.
100 - Schema documentation now includes an entity-relationship diagram.
101 - The database is now garbage collected. In most tables,
102 unreferenced rows will be deleted automatically.
103 - Many tables now include statistics updated periodically by
104 ovs-vswitchd or ovsdb-server.
105 - Every table now has an "external-ids" column for use by OVS
107 - There is no default controller anymore. Each bridge must have its
108 controller individually specified.
109 - The "fail-mode" is now a property of a Bridge instead of a Controller.
110 - New versioning and checksum features.
111 - New Managers table and manager_options column in Open_vSwitch table
