-Post-v1.2.0
+post-v1.5.0
------------------------
+
+
+v1.5.0 - xx xxx xxxx
+------------------------
+ - OpenFlow:
+ - Added support for querying, modifying, and deleting flows
+ based on flow cookie when using NXM.
+ - Added new NXM_PACKET_IN format.
+ - Added new NXAST_DEC_TTL action.
+ - ovs-ofctl:
+ - Added daemonization support to the monitor and snoop commands.
+ - ovs-vsctl:
+ - The "find" command supports new set relational operators
+ {=}, {!=}, {<}, {>}, {<=}, and {>=}.
+ - ovsdb-tool now uses the typical database and schema installation
+ directories as defaults.
+
+
+v1.4.0 - xx xxx xxxx
+------------------------
+ - New "VLAN splinters" feature to work around buggy device drivers
+ in old Linux versions. (This feature is deprecated. When
+ broken device drivers are no longer in widespread use, we will
+ delete this feature.) See ovs-vswitchd.conf.db(5) for more
+ information.
+ - OpenFlow:
+ - Added ability to match on IPv6 flow label through NXM.
+ - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
+ - Added ability to match on TTL in IPv4 and IPv6 through NXM.
+ - Added ability to modify ECN bits in IPv4.
+ - Added ability to modify TTL in IPv4.
+ - ovs-vswitchd:
+ - Don't require the "normal" action to use mirrors. Traffic will
+ now be properly mirrored for any flows, regardless of their
+ actions.
+ - Track packet and byte statistics sent on mirrors.
+ - The sFlow implementation can now usually infer the correct agent
+ device instead of having to be told explicitly.
+ - ovs-appctl:
+ - New "fdb/flush" command to flush bridge's MAC learning table.
+ - ovs-test:
+ - A new distributed testing tool that allows one to diagnose performance
+ and connectivity issues. This tool currently is not included in RH or
+ Xen packages.
+ - RHEL packaging now supports integration with Red Hat network scripts.
+ - bonding:
+ - Post 1.4.*, OVS will be changing the default bond mode from balance-slb
+ to active-backup. SLB bonds carry significant risks with them
+ (documented vswitchd/INTERNALS) which we want to prevent unsuspecting
+ users from running into. Users are advised to update any scripts or
+ configuration which may be negatively impacted by explicitly setting
+ the bond mode which they want to use.
+
+
+v1.3.0 - 09 Dec 2011
+------------------------
+ - OpenFlow:
+ - Added an OpenFlow extension which allows the "output" action to accept
+ NXM fields.
+ - Added an OpenFlow extension for flexible learning.
+ - Bumped number of NXM registers from four to five.
- ovs-appctl:
- - New "version" command to determine version of running daemon
+ - New "version" command to determine version of running daemon.
+ - If no argument is provided for "cfm/show", displays detailed
+ information about all interfaces with CFM enabled.
+ - If no argument is provided for "lacp/show", displays detailed
+ information about all ports with LACP enabled.
+ - ovs-dpctl:
+ - New "set-if" command to modify a datapath port's configuration.
+ - ovs-vswitchd:
+ - The software switch now supports 255 OpenFlow tables, instead
+ of just one. By default, only table 0 is consulted, but the
+ new NXAST_RESUBMIT_TABLE action can look up in additional
+ tables. Tables 128 and above are reserved for use by the
+ switch itself; please use only tables 0 through 127.
+ - Add support for 802.1D spanning tree (STP).
+ - Fragment handling extensions:
+ - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
+ fields are made available for matching in fragments with
+ offset 0.
+ - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
+ via "ip_frag" in ovs-ofctl).
+ - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
+ fragment handling policy.
+ - CAPWAP tunneling now supports an extension to transport a 64-bit key.
+ By default it remains compatible with the old version and other
+ standards-based implementations.
+ - Flow setups are now processed in a round-robin manner across ports
+ to prevent any single client from monopolizing the CPU and conducting
+ a denial of service attack.
+ - Added support for native VLAN tagging. A new "vlan_mode"
+ parameter can be set for "port". Possible values: "access",
+ "trunk", "native-tagged" and "native-untagged".
+ - test-openflowd has been removed. Please use ovs-vswitchd instead.
