+post-v1.9.0
+--------------------
+ - Bridge compatibility support has been removed. Any uses that
+ rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x
+ or adapt to native Open vSwitch support (e.g. use ovs-vsctl instead
+ of brctl).
+ - The maximum size of the MAC learning table is now configurable.
+ - New support for the VXLAN tunnel protocol (see the IETF draft here:
+ http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02).
+ - With the Linux datapath, packets for new flows are now queued
+ separately on a per-port basis, so it should no longer be
+ possible for a large number of new flows arriving on one port to
+ prevent new flows from being processed on other ports.
+ - Many "ovs-vsctl" database commands now accept an --if-exists option.
+ Please refer to the ovs-vsctl manpage for details.
+ - New "vlog/disable-rate-limit" and "vlog/enable-rate-limit" commands
+ available through ovs-appctl allow control over logging rate limits.
+ - The OpenFlow "dp_desc" may now be configured by setting the value of
+ other-config:dp-desc in the Bridge table.
+ - Path MTU discovery is no longer supported.
+ - Backward-incompatible changes:
+ - Earlier Open vSwitch versions treated ANY as a wildcard in flow
+ syntax. OpenFlow 1.1 adds a port named ANY, which introduces a
+ conflict. ANY was rarely used in flow syntax, so we chose to
+ retire that meaning of ANY in favor of the OpenFlow 1.1 meaning.
+ - Inheritance of the Don't Fragment bit in IP tunnels (df_inherit) is
+ no longer supported.
+ - Patch ports are implemented in userspace.
+ - Tunneling requires the version of the kernel module paired with Open
+ vSwitch 1.9.0 or later.
+
+
+v1.9.0 - xx xxx xxxx
+--------------------
+ - The tunneling code no longer assumes input and output keys are symmetric.
+ If they are not, PMTUD needs to be disabled for tunneling to work. Note
+ this only applies to flow-based keys.
+ - Datapath:
+ - Support for ipv6 set action.
+ - SKB mark matching and setting.
+ - support for Linux kernels up to 3.8
+ - FreeBSD is now a supported platform, thanks to code contributions from
+ Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.
+ - ovs-bugtool: New --ovs option to report only OVS related information.
+ - New %t and %T log escapes to identify the subprogram within a
+ cooperating group of processes or threads that emitted a log message.
+ The default log patterns now include this information.
+ - OpenFlow:
+ - Allow bitwise masking for SHA and THA fields in ARP, SLL and TLL
+ fields in IPv6 neighbor discovery messages, and IPv6 flow label.
+ - Adds support for writing to the metadata field for a flow.
+ - It is possible to request the OpenFlow port number with the
+ "ofport_request" column in the Interface table.
+ - ovs-ofctl:
+ - Commands and actions that accept port numbers now also accept keywords
+ that represent those ports (such as LOCAL, NONE, and ALL). This is
+ also the recommended way to specify these ports, for compatibility
+ with OpenFlow 1.1 and later (which use the OpenFlow 1.0 numbers
+ for these ports for different purposes).
+ - ovs-dpctl:
+ - Support requesting the port number with the "port_no" option in
+ the "add-if" command.
+ - The "dump-flows" and "del-flows" no longer require an argument
+ if only one datapath exists.
+ - ovs-appctl:
+ - New "dpif/dump-dps", "dpif/show", and "dpif/dump-flows" command
+ that mimic the equivalent ovs-dpctl commands.
+ - ovs-pki: The "online PKI" features have been removed, along with
+ the ovs-pki-cgi program that facilitated it, because of some
+ alarmist insecurity claims. We do not believe that these claims
+ are true, but because we do not know of any users for this
+ feature it seems better on balance to remove it. (The ovs-pki-cgi
+ program was not included in distribution packaging.)
+ - Tunnel Path MTU Discovery default value was set to 'disabled'. This
+ feature is deprecated and will be removed soon.
+ - ovsdb-server now enforces the immutability of immutable columns. This
+ was not enforced in earlier versions due to an oversight.
+ - New support for a nonstandard form of GRE that supports a 64-bit key.
+ - The ofproto library is now responsible for assigning OpenFlow port
+ numbers. An ofproto implementation should assign them when
+ port_construct() is called.
+ - All dpif-based bridges of a particular type share a common
+ datapath called "ovs-<type>", e.g. "ovs-system". The ovs-dpctl
+ commands will now return information on that shared datapath. To
+ get the equivalent bridge-specific information, use the new
+ "ovs-appctl dpif/*" commands.
+ - Tunnel header caching removed.
+ - The following features are now deprecated. They will be removed no
+ earlier than February 2013. Please email dev@openvswitch.org with
+ concerns.
+ - Bridge compatibility.
+ - Stable bond mode.
+ - The autopath action.
+ - Interface type "null".
+ - Numeric values for reserved ports (see "ovs-ofctl" note above).
+ - Tunnel Path MTU Discovery.
+ - CAPWAP tunnel support.
+ - The data in the RARP packets can now be matched in the same way as the
+ data in ARP packets.
