-Post-v2.0.0
+Post-v2.2.0
+---------------------
+ - 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.
+
+v2.2.0 - xx xxx xxx
+---------------------
+ - 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.
+ - 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
- 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+ - The flow-eviction-threshold has been replaced by the flow-limit which is a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.
