7 - ovs-brcompatd has been rewritten to fix long-standing bugs.

9 tests directory. Its presence confused too many users. Please
10 use ovs-vswitchd instead.
11 - "configure" option --with-l26 has been renamed --with-linux, and
12 --with-l26-source has been renamed --with-linux-source. The old
13 names will be removed after the next release, so please update

16 datapath/linux-2.6/compat-2.6 directories.
18 - Dropped support for "tun_id_from_cookie" OpenFlow extension.
19 (Use the extensible match extensions instead.)
20 - Removed the Maintenance_Point and Monitor tables in an effort
21 to simplify 802.1ag configuration.

25 - Ability to define policies over IPv6
28 - Support for extensible match extensions to OpenFlow
30 - Support for HFSC qdisc.

58 - New --more option to increase OpenFlow message verbosity.
59 - Removed "tun-cookie" command, which is no longer useful.
60 - ovs-controller enhancements for testing various features.
61 - New ovs-vlan-test command for testing for Linux kernel driver VLAN
62 bugs. New ovs-vlan-bug-workaround command for enabling and
63 disabling a workaround for these driver bugs.

70 - New extension to set the QoS output queue without actually
71 sending to an output port.

73 separate hash and wildcard tables. This better models the
74 current implementation.

76 - New "ofproto/trace" ovs-appctl command and associated utilities
77 to ease debugging complex flow tables.
79 - Schema documentation now includes an entity-relationship diagram.
80 - The database is now garbage collected. In most tables,
81 unreferenced rows will be deleted automatically.
82 - Many tables now include statistics updated periodically by
83 ovs-vswitchd or ovsdb-server.
84 - Every table now has an "external-ids" column for use by OVS

87 controller individually specified.
88 - The "fail-mode" is now a property of a Bridge instead of a Controller.
89 - New versioning and checksum features.
