2 ------------------------
4 - A new log level "off" has been added. Configuring a log facility
5 "off" prevents any messages from being logged to it. Previously,
6 "emer" was effectively "off" because no messages were ever logged at
7 level "emer". Now, errors that cause a process to exit are logged
9 - The new "-s" option for "ovs-dpctl show" prints packet and byte
10 counters for each port.
12 - New "--readd" option for "replace-flows".
14 - New "show" command to print an overview of configuration.
15 - ovs-brcompatd has been rewritten to fix long-standing bugs.
16 - ovs-openflowd has been renamed test-openflowd and moved into the
17 tests directory. Its presence confused too many users. Please
18 use ovs-vswitchd instead.
19 - "configure" option --with-l26 has been renamed --with-linux, and
20 --with-l26-source has been renamed --with-linux-source. The old
21 names will be removed after the next release, so please update
23 - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
24 datapath/linux-2.6/compat-2.6 directories.
26 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
27 (Use the extensible match extensions instead.)
28 - Removed the Maintenance_Point and Monitor tables in an effort
29 to simplify 802.1ag configuration.
32 ------------------------
33 - Ability to define policies over IPv6
36 - Support for extensible match extensions to OpenFlow
38 - Support for HFSC qdisc.
39 - Queue used by in-band control can now be configured.
41 - Kernel<->userspace interface has been reworked and should be
42 close to a stable ABI now.
43 - "Port group" concept has been dropped.
44 - GRE over IPSEC tunnels
46 - New active backup bonding mode.
47 - New L4 hashing support when LACP is enabled.
48 - Source MAC hash now includes VLAN field also.
50 - Greatly improved handling of large flow tables
52 - "show" command now prints full vport configuration.
53 - "dump-groups" command removed since kernel support for
54 port groups was dropped.
56 - New commands for working with the new Managers table.
57 - "list" command enhanced with new formatting options and --columns
59 - "get" command now accepts new --id option.
62 - New "queue-stats" command for printing queue stats.
63 - New commands "replace-flows" and "diff-flows".
64 - Commands to add and remove flows can now read from files.
65 - New --flow-format option to enable or disable NXM.
66 - New --more option to increase OpenFlow message verbosity.
67 - Removed "tun-cookie" command, which is no longer useful.
68 - ovs-controller enhancements for testing various features.
69 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
70 bugs. New ovs-vlan-bug-workaround command for enabling and
71 disabling a workaround for these driver bugs.
73 - "Resubmit" actions now update flow statistics.
74 - New "register" extension for use in matching and actions, via NXM.
75 - New "multipath" experimental action extension.
76 - New support for matching multicast Ethernet frames, via NXM.
77 - New extension for OpenFlow vendor error codes.
78 - New extension to set the QoS output queue without actually
79 sending to an output port.
80 - Open vSwitch now reports a single flow table, instead of
81 separate hash and wildcard tables. This better models the
82 current implementation.
83 - New experimental "note" action.
84 - New "ofproto/trace" ovs-appctl command and associated utilities
85 to ease debugging complex flow tables.
87 - Schema documentation now includes an entity-relationship diagram.
88 - The database is now garbage collected. In most tables,
89 unreferenced rows will be deleted automatically.
90 - Many tables now include statistics updated periodically by
91 ovs-vswitchd or ovsdb-server.
92 - Every table now has an "external-ids" column for use by OVS
94 - There is no default controller anymore. Each bridge must have its
95 controller individually specified.
96 - The "fail-mode" is now a property of a Bridge instead of a Controller.
97 - New versioning and checksum features.
98 - New Managers table and manager_options column in Open_vSwitch table
99 for specifying managers. The old "managers" column in the
100 Open_vSwitch table has been removed.
101 - Many "name" columns are now immutable.
103 - Dropped support for XenServer pre-5.6.100.
104 - Dropped support for Linux pre-2.6.18.
105 - Dropped controller discovery support.
106 - Dropped "ovs-ofctl status" and the OpenFlow extension that it used.
107 Statistics reporting in the database is a rough equivalent.
108 - Dropped the "corekeeper" package (now separate, at
109 http://openvswitch.org/cgi-bin/gitweb.cgi?p=corekeeper).
