+v2.9.0 - 19 Feb 2018
+--------------------
+ - NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
+ * Add ttl field.
+ * Add a new action dec_nsh_ttl.
+ * Enable NSH support in kernel datapath.
+ - OVSDB:
+ * 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" and "query" commands.
+ * ovsdb-client: New "backup" and "restore" commands.
+ * ovsdb-tool: New "db-name" and "schema-name" commands.
+ - 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".
+ * IPv6
+ - Added support to send IPv6 Router Advertisement packets in response to
+ the IPv6 Router Solicitation packets from the VIF ports.
+ - Added support to generate Neighbor Solicitation packets using the OVN
+ 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.
+ - OpenFlow:
+ * ct_clear action is now backed by kernel datapath. Support is probed for
+ when OVS starts.
+ - Linux kernel 4.15
+ * Add support for compiling OVS with the latest Linux 4.15 kernel
+ - 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+).
+ * 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.
+
+v2.8.0 - 31 Aug 2017
+--------------------
- ovs-ofctl:
* ovs-ofctl can now accept and display port names in place of numbers. By
default it always accepts names and in interactive use it displays them;
abbreviated to 4 hex digits.
- Userspace Datapath:
* Added NAT support for userspace datapath.
+ * Added FTP and TFTP support with NAT for userspace datapath.
+ * Experimental NSH (Network Service Header) support in userspace datapath.
- OVN:
* New built-in DNS support.
* IPAM for IPv4 can now exclude user-defined addresses from assignment.
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.
- Tracing with ofproto/trace now traces through recirculation.
- OVSDB:
* New support for role-based access control (see ovsdb-server(1)).
pipeline (PTAP).
* Added generic encap and decap actions (EXT-382).
First supported use case is encap/decap for Ethernet.
+ * Added NSH (Network Service Header) support in userspace
+ Used generic encap and decap actions to implement encapsulation and
+ decapsulation of NSH header.
+ IETF NSH draft - https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/
+ * Conntrack state is only available to the processing path that
+ follows the "recirc_table" argument of the ct() action. Starting
+ in OVS 2.8, this state is now cleared for the current processing
+ path whenever ct() is called.
- Fedora Packaging:
* OVN services are no longer restarted automatically after upgrade.
+ * ovs-vswitchd and ovsdb-server run as non-root users by default.
- Add --cleanup option to command 'ovs-appctl exit' (see ovs-vswitchd(8)).
- L3 tunneling:
* Use new tunnel port option "packet_type" to configure L2 vs. L3.
