-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 1.5 (draft) masked Set-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.
+ * "resubmit" actions may now be included in action sets. The resubmit
+ is executed last, and only if the action set has no "output" or "group"
+ action.
+ - ovs-pki: Changed message digest algorithm from MD5 to SHA-1 because
+ MD5 is no longer secure and some operating systems have started to disable
+ it in OpenSSL.
+ - ovsdb-server: New OVSDB protocol extension allows inequality tests on
+ "optional scalar" columns. See ovsdb-server(1) for details.
+ - ovs-vsctl now permits immutable columns in a new row to be modified in
+ the same transaction that creates the row.
+ - 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.
+ - Support for travis-ci.org based continuous integration builds has been
+ added. Build failures are reported to build@openvswitch.org. See INSTALL.md
+ file for additional details.
+ - Experimental support for the Rapid Spanning Tree Protocol
+ (IEEE 802.1D-2004). More conformance and interoperability testing is
+ still needed, so this should not be enabled on production environments.
+ - Stats are no longer updated on fake bond interface.
+ - Keep active bond slave selection across OVS restart.
+ - A simple wrapper script, 'ovs-docker', to integrate OVS with Docker
+ containers.
+
+
+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.md 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
+ tracking allows the classifier to skip rules with longer than
+ necessary prefixes, resulting in better wildcarding for datapath
+ flows. Default configuration is to not use any fields for prefix
+ tracking. However, if any flow tables contain both exact matches
+ and masked matches for IP address fields, OVS performance may be
+ increased by using this feature.
+ * As of now, the fields for which prefix lookup can be enabled
+ are: 'tun_id', 'tun_src', 'tun_dst', 'nw_src', 'nw_dst' (or
+ aliases 'ip_src' and 'ip_dst'), 'ipv6_src', and 'ipv6_dst'.
+ (Using this feature for 'tun_id' would only make sense if the
+ tunnel IDs have prefix structure similar to IP addresses.)
+ * There is a maximum number of fields that can be enabled for any
+ one flow table. Currently this limit is 3.
+ * Examples:
+ $ ovs-vsctl set Bridge br0 flow_tables:0=@N1 -- \
+ --id=@N1 create Flow_Table name=table0
+ $ ovs-vsctl set Bridge br0 flow_tables:1=@N1 -- \
+ --id=@N1 create Flow_Table name=table1
+ $ ovs-vsctl set Flow_Table table0 prefixes=ip_dst,ip_src
+ $ ovs-vsctl set Flow_Table table1 prefixes=[]
+ - TCP flags matching: OVS now supports matching of TCP flags. This
+ has an adverse performance impact when using OVS userspace 1.10
+ or older (no megaflows support) together with the new OVS kernel
+ module. It is recommended that the kernel and userspace modules
+ both are upgraded at the same time.
- The default OpenFlow and OVSDB ports will change to
IANA-assigned numbers in a future release. Consider updating
your installations to specify port numbers instead of using the
defaults.
- OpenFlow:
* The OpenFlow 1.1+ "Write-Actions" instruction is now supported.
+ * OVS limits the OpenFlow port numbers it assigns to port 32767 and
+ below, leaving port numbers above that range free for assignment
+ by the controller.
+ * ovs-vswitchd now honors changes to the "ofport_request" column
+ in the Interface table by changing the port's OpenFlow port
+ number.
- ovs-vswitchd.conf.db.5 man page will contain graphviz/dot
diagram only if graphviz package was installed at the build time.
- 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.
