---------------------
+
+
+v1.12.0 - xx xxx xxxx
+---------------------
+ - OpenFlow:
+ * Experimental support for OpenFlow 1.1 (in addition to 1.2 and
+ 1.3, which had experimental support in 1.10).
+ * New support for matching outer source and destination IP address
+ of tunneled packets, for tunnel ports configured with the newly
+ added "remote_ip=flow" and "local_ip=flow" options.
+ * Support for matching on metadata 'pkt_mark' for interacting with
+ other system components. On Linux this corresponds to the skb
+ mark.
+ - The Interface table in the database has a new "ifindex" column to
+ report the interface's OS-assigned ifindex.
+ - New "check-oftest" Makefile target for running OFTest against Open
+ vSwitch. See README-OFTest for details.
+ - The flow eviction threshold has been moved to the Open_vSwitch table.
+ - Database names are now mandatory when specifying ovsdb-server options
+ through database paths (e.g. Private key option with the database name
+ should look like "--private-key=db:Open_vSwitch,SSL,private_key").
+ - Added ovs-dev.py, a utility script helpful for Open vSwitch developers.
+ - Support for Linux kernels up to 3.10
+ - ovs-ofctl:
+ * New "ofp-parse" for printing OpenFlow messages read from a file.
+
+
+v1.11.0 - xx xxx xxxx
+---------------------
+ - Support for megaflows, which allows wildcarding in the kernel (and
+ any dpif implementation that supports wildcards). Depending on
+ the flow table and switch configuration, flow set up rates are
+ close to the Linux bridge.
+ - The "tutorial" directory contains a new tutorial for some advanced
+ Open vSwitch features.
- Stable bond mode has been removed.
- The autopath action has been removed.
- New support for the data encapsulation format of the LISP tunnel
1.1 and later are now implemented.
* New "stack" extension for use in actions, to push and pop from
NXM fields.
+ * The "load" and "set_field" actions can now modify the "in_port". (This
+ allows one to enable output to a flow's input port by setting the
+ in_port to some unused value, such as OFPP_NONE.)
+ - ovs-dpctl:
+ * New debugging commands "add-flow", "mod-flow", "del-flow".
+ * "dump-flows" now has a -m option to increase output verbosity.
+ - In dpif-based bridges, cache action translations, which can improve
+ flow set up performance by 80% with a complicated flow table.
+ - New syslog format, prefixed with "ovs|", to be easier to filter.
+ - RHEL: Removes the default firewall rule that allowed GRE traffic to
+ pass through. Any users that relied on this automatic firewall hole
+ will have to manually configure it. The ovs-ctl(8) manpage documents
+ the "enable-protocol" command that can be used as an alternative.
+ - New CFM demand mode which uses data traffic to indicate interface
+ liveness.

-v1.10.0 - xx xxx xxxx
+v1.10.0 - 01 May 2013
---------------------
- Bridge compatibility support has been removed. Any uses that
rely on ovs-brcompatd will have to stick with Open vSwitch 1.9.x
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.
+ - ovs-vsctl:
+ * Previously ovs-vsctl would retry connecting to the database forever,
+ causing it to hang if ovsdb-server was not running. Now, ovs-vsctl
+ only tries once by default (use --retry to try forever). This change
+ means that you may want to remove uses of --timeout to avoid hangs
+ in ovs-vsctl calls.
+ * Many "ovs-vsctl" database commands now accept an --if-exists option.
+ Please refer to the ovs-vsctl manpage for details.
- OpenFlow:
- Experimental support for newer versions of OpenFlow. See
the "What versions of OpenFlow does Open vSwitch support?"
retire that meaning of ANY in favor of the OpenFlow 1.1 meaning.
- Patch ports no longer require kernel support, so they now work
with FreeBSD and the kernel module built into Linux 3.3 and later.
+ - New "sample" action.
