-Post-v2.0.0
+Post-v2.3.0
+---------------------
+ - The "learn" action supports a new flag "delete_learned" that causes
+ the learned flows to be deleted when the flow with the "learn" action
+ is deleted.
+ - Basic support for the Geneve tunneling protocol. It is not yet
+ possible to generate or match options. This is planned for a future
+ release. The protocol is documented at
+ http://tools.ietf.org/html/draft-gross-geneve-00
+ - The OVS database now reports controller rate limiting statistics.
+ - ovs-dpctl functionality is now available for datapaths integrated
+ into ovs-vswitchd, via ovs-appctl. Some existing ovs-appctl
+ commands are now redundant and will be removed in a future
+ release. See ovs-vswitchd(8) for details.
+ - OpenFlow:
+ * OpenFlow 1.5 (draft) extended registers are now supported.
+ * OpenFlow 1.5 (draft) Copy-Field action is now supported.
+ * OpenFlow 1.3+ table features requests are now supported (read-only).
+ * Nicira extension "move" actions may now be included in action sets.
+ - ovsdb-server: New OVSDB protocol extension allows inequality tests on
+ "optional scalar" columns. See ovsdb-server(1) for details.
+ - test-controller has been renamed ovs-testcontroller at request of users
+ who find it useful for testing basic OpenFlow setups. It is still not
+ a necessary or desirable part of most Open vSwitch deployments.
+
+
+v2.3.0 - 14 Aug 2014
+---------------------
+ - OpenFlow 1.1, 1.2, and 1.3 are now enabled by default in
+ ovs-vswitchd.
+ - Linux kernel datapath now has an exact match cache optimizing the
+ flow matching process.
+ - Datapath flows now have partially wildcarded tranport port field
+ matches. This reduces userspace upcalls, but increases the
+ number of different masks in the datapath. The kernel datapath
+ exact match cache removes the overhead of matching the incoming
+ packets with the larger number of masks, but when paired with an
+ older kernel module, some workloads may perform worse with the
+ new userspace.
+ - Support for multicast snooping (IGMPv1 and IGMPv2)
+ - Compatibility with autoconf 2.63 (previously >=2.64)
+
+v2.2.0 - Internal Release
+---------------------
+ - Internal ports are no longer brought up by default, because it
+ should be an administrator task to bring up devices as they are
+ configured properly.
+ - ovs-vsctl now reports when ovs-vswitchd fails to create a new port or
+ bridge.
+ - Port creation and configuration errors are now stored in a new error
+ column of the Interface table and included in 'ovs-vsctl show'.
+ - The "ovsdbmonitor" graphical tool has been removed, because it was
+ poorly maintained and not widely used.
+ - New "check-ryu" Makefile target for running Ryu tests for OpenFlow
+ controllers against Open vSwitch. See INSTALL for details.
+ - Added IPFIX support for SCTP flows and templates for ICMPv4/v6 flows.
+ - Upon the receipt of a SIGHUP signal, ovs-vswitchd no longer reopens its
+ log file (it will terminate instead). Please use 'ovs-appctl vlog/reopen'
+ instead.
+ - Support for Linux kernels up to 3.14. From Kernel 3.12 onwards OVS uses
+ tunnel API for GRE and VXLAN.
+ - Added DPDK support.
+ - Added support for custom vlog patterns in Python
+
+
+v2.1.0 - 19 Mar 2014
---------------------
-
- Address prefix tracking support for flow tables. New columns
"prefixes" in OVS-DB table "Flow_Table" controls which packet
header fields are used for address prefix tracking. Prefix
- Support for Linux kernels up to 3.11
- ovs-dpctl:
The "show" command also displays mega flow mask stats.
+ - ovs-ofctl:
+ * New command "ofp-parse-pcap" to dump OpenFlow from PCAP files.
- ovs-controller has been renamed test-controller. It is no longer
packaged or installed by default, because too many users assumed
incorrectly that ovs-controller was a necessary or desirable part
of an Open vSwitch deployment.
- Added vlog option to export to a UDP syslog sink.
+ - ovsdb-client:
+ * The "monitor" command can now monitor all tables in a database,
+ instead of being limited to a single table.
+ - The flow-eviction-threshold has been replaced by the flow-limit which is a
+ hard limit on the number of flows in the datapath. It defaults to 200,000
+ flows. OVS automatically adjusts this number depending on network
+ conditions.
+ - Added IPv6 support for active and passive socket communications.
