-Post-v2.8.0
+Post-v2.9.0
+--------------------
+ - ovs-vswitchd:
+ * New options --l7 and --l7-len to "ofproto/trace" command.
+ * Previous versions gave OpenFlow tables default names of the form
+ "table#". These are not helpful names for the purpose of accepting
+ and displaying table names, so now tables by default have no names.
+ * The "null" interface type, deprecated since 2013, has been removed.
+ * Add minimum network namespace support for Linux.
+ * New command "lacp/show-stats"
+ - ovs-ofctl:
+ * ovs-ofctl now accepts and display table names in place of numbers. By
+ default it always accepts names and in interactive use it displays them;
+ use --names or --no-names to override. See ovs-ofctl(8) for details.
+ - ovs-vsctl: New commands "add-bond-iface" and "del-bond-iface".
+ - OpenFlow:
+ * OFPT_ROLE_STATUS is now available in OpenFlow 1.3.
+ - Linux kernel 4.14
+ * Add support for compiling OVS with the latest Linux 4.14 kernel
+ - ovn:
+ * implemented icmp4/icmp6/tcp_reset actions in order to drop the packet
+ and reply with a RST for TCP or ICMPv4/ICMPv6 unreachable message for
+ other IPv4/IPv6-based protocols whenever a reject ACL rule is hit.
+ * ACL match conditions can now match on Port_Groups as well as address
+ sets that are automatically generated by Port_Groups.
+
+v2.9.0 - 19 Feb 2018
--------------------
- NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
- - OVSDB:
+ * Add ttl field.
+ * Add a new action dec_nsh_ttl.
+ * Enable NSH support in kernel datapath.
+ - OVSDB has new, experimental support for database clustering:
* New high-level documentation in ovsdb(7).
* New file format documentation for developers in ovsdb(5).
* Protocol documentation moved from ovsdb-server(1) to ovsdb-server(7).
- * ovsdb-client: New "get-schema-cksum" command.
- * ovsdb-client: New "backup" command.
- * ovsdb-tool: New "db-name" and "schema-name" commands.
+ * ovsdb-server now supports online schema conversion via
+ "ovsdb-client convert".
+ * ovsdb-server now always hosts a built-in database named _Server. See
+ ovsdb-server(5) for more details.
+ * ovsdb-client: New "get-schema-cksum", "query", "backup", "restore",
+ and "wait" commands. New --timeout option.
+ * ovsdb-tool: New "create-cluster", "join-cluster", "db-cid", "db-sid",
+ "db-local-address", "db-is-clustered", "db-is-standalone", "db-name",
+ "schema-name", "compare-versions", and "check-cluster" commands.
+ * ovsdb-server: New ovs-appctl commands for managing clusters.
+ * ovs-sandbox: New support for clustered databases.
+ - ovs-vsctl and other commands that display data in tables now support a
+ --max-column-width option to limit column width.
+ - No longer slow-path traffic that sends to a controller. Applications,
+ such as OVN ACL logging, want to send a copy of a packet to a
+ controller while leaving the actual packet forwarding in the datapath.
- OVN:
* The "requested-chassis" option for a logical switch port now accepts a
chassis "hostname" in addition to a chassis "name".
action 'nd_ns' to resolve unknown next hop MAC addresses for the
IPv6 packets.
* ovn-ctl: New commands run_nb_ovsdb and run_sb_ovsdb.
+ * ovn-sbctl, ovn-nbctl: New options --leader-only, --no-leader-only.
+ - OpenFlow:
+ * ct_clear action is now backed by kernel datapath. Support is probed for
+ when OVS starts.
- Linux kernel 4.13
* Add support for compiling OVS with the latest Linux 4.13 kernel
- - "flush-conntrack" in ovs-dpctl and ovs-appctl now accept a 5-tuple to
- delete a specific connection tracking entry.
+ - ovs-dpctl and related ovs-appctl commands:
+ * "flush-conntrack" now accept a 5-tuple to delete a specific
+ connection tracking entry.
+ * New "ct-set-maxconns", "ct-get-maxconns", and "ct-get-nconns" commands
+ for userspace datapath.
+ - No longer send packets to the Linux TAP device if it's DOWN unless it is
+ in another networking namespace.
- DPDK:
* Add support for DPDK v17.11
* Add support for vHost IOMMU
+ * New debug appctl command 'netdev-dpdk/get-mempool-info'.
+ * All the netdev-dpdk appctl commands described in ovs-vswitchd man page.
+ * Custom statistics:
+ - DPDK physical ports now return custom set of "dropped", "error" and
+ "management" statistics.
+ - ovs-ofctl dump-ports command now prints new of set custom statistics
+ if available (for OpenFlow 1.4+).
+ * Switch from round-robin allocation of rxq to pmd assignments to a
+ utilization-based allocation.
+ * New appctl command 'dpif-netdev/pmd-rxq-rebalance' to rebalance rxq to
+ pmd assignments.
+ * Add rxq utilization of pmd to appctl 'dpif-netdev/pmd-rxq-show'.
+ * Add support for vHost dequeue zero copy (experimental)
+ - Userspace datapath:
+ * Output packet batching support.
- vswitchd:
* Datapath IDs may now be specified as 0x1 (etc.) instead of 16 digits.
+ * Configuring a controller, or unconfiguring all controllers, now deletes
+ all groups and meters (as well as all flows).
+ - New --enable-sparse configure option enables "sparse" checking by default.
+ - Added additional information to vhost-user status.

gateway.
* Add support for ACL logging.
* ovn-northd now has native support for active-standby high availability.
+ * Add support for QoS bandwidth limt with DPDK.
