+
+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.
+ - 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.
+ - 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.
+
+v1.8.0 - xx xxx xxxx
------------------------
+ - New FAQ. Please send updates and additions!
+ - Authors of controllers, please read the new section titled "Action
+ Reproduction" in DESIGN, which describes an Open vSwitch change in
+ behavior in corner cases that may affect some controllers.
+ - ovs-l3ping:
+ - A new test utility that can create L3 tunnel between two Open
+ vSwitches and detect connectivity issues.
- ovs-ofctl:
+ - New --sort and --rsort options for "dump-flows" command.
- "mod-port" command can now control all OpenFlow config flags.
- - Added support for arbitrary ethernet masks
+ - OpenFlow:
+ - Allow general bitwise masking for IPv4 and IPv6 addresses in
+ IPv4, IPv6, and ARP packets. (Previously, only CIDR masks
+ were allowed.)
+ - Allow support for arbitrary Ethernet masks. (Previously, only
+ the multicast bit in the destination address could be individually
+ masked.)
+ - New field OXM_OF_METADATA, to align with OpenFlow 1.1.
+ - The OFPST_QUEUE request now reports an error if a specified port or
+ queue does not exist, or for requests for a specific queue on all
+ ports, if the specified queue does not exist on any port. (Previous
+ versions generally reported an empty set of results.)
+ - New "flow monitor" feature to allow controllers to be notified of
+ flow table changes as they happen.
+ - Additional protocols are not mirrored and dropped when forward-bpdu is
+ false. For a full list, see the ovs-vswitchd.conf.db man page.
+ - Open vSwitch now sends RARP packets in situations where it previously
+ sent a custom protocol, making it consistent with behavior of QEMU and
+ VMware.
+ - All Open vSwitch programs and log files now show timestamps in UTC,
+ instead the local timezone, by default.
-v1.7.0 - xx xxx xxxx
+v1.7.0 - 30 Jul 2012
------------------------
- kernel modules are renamed. openvswitch_mod.ko is now
openvswitch.ko and brcompat_mod.ko is now brcompat.ko.
- Increased the number of NXM registers to 8.
- - Added ability to configure dscp setting for manager and controller
+ - Added ability to configure DSCP setting for manager and controller
connections. By default, these connections have a DSCP value of
Internetwork Control (0xc0).
- Added the granular link health statistics, 'cfm_health', to an
- Added support for spawning ovs-test server from the client.
- Now ovs-test is able to automatically create test bridges and ports.
- "ovs-dpctl dump-flows" now prints observed TCP flags in TCP flows.
+ - Tripled flow setup performance.
- The "coverage/log" command previously available through ovs-appctl
has been replaced by "coverage/show". The new command replies with
coverage counter values, instead of logging them.
-v1.6.0 - xx xxx xxxx
+v1.6.1 - 25 Jun 2012
+------------------------
+ - Allow OFPP_CONTROLLER as the in_port for packet-out messages.
+
+
+v1.6.0 - 24 Feb 2012
------------------------
+ *** Internal only release ***
- bonding
- LACP bonds no longer fall back to balance-slb when negotiations fail.
Instead they drop traffic.
- Added "fin_timeout" support to "learn" action.
- New Nicira action NXAST_CONTROLLER that offers additional features
over output to OFPP_CONTROLLER.
- - The default MAC learning timeout has been increased from 60 seconds
- to 300 seconds. The MAC learning timeout is now configurable.
- When QoS settings for an interface do not configure a default queue
(queue 0), Open vSwitch now uses a default configuration for that
queue, instead of dropping all packets as in previous versions.
- CFM module CCM broadcasts can now be tagged with an 802.1p priority.
-v1.5.0 - xx xxx xxxx
+v1.5.0 - 01 Jun 2012
------------------------
- OpenFlow:
- Added support for querying, modifying, and deleting flows
{=}, {!=}, {<}, {>}, {<=}, and {>=}.
- ovsdb-tool now uses the typical database and schema installation
directories as defaults.
+ - The default MAC learning timeout has been increased from 60 seconds
+ to 300 seconds. The MAC learning timeout is now configurable.
