-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.
+ - OpenFlow:
+ * OpenFlow 1.5 (draft) extended registers are now supported.
+
+v2.3.0 - xx xxx xxxx
+---------------------
+ - 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
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.
