+v2.4.0 - xx xxx xxxx
---------------------
- Flow table modifications are now atomic, meaning that each packet
now sees a coherent version of the OpenFlow pipeline. For
commands are now redundant and will be removed in a future
release. See ovs-vswitchd(8) for details.
- OpenFlow:
- * OpenFlow 1.4 bundles are now supported, but for flow mod
- messages only. Both 'atomic' and 'ordered' bundle flags are
- trivially supported, as all bundled messages are executed in
- the order they were added and all flow table modifications are
- now atomic to the datapath.
+ * OpenFlow 1.4 bundles are now supported for flow mods and port
+ mods. For flow mods, both 'atomic' and 'ordered' bundle flags
+ are trivially supported, as all bundled messages are executed
+ in the order they were added and all flow table modifications
+ are now atomic to the datapath. Port mods may not appear in
+ atomic bundles, as port status modifications are not atomic.
* IPv6 flow label and neighbor discovery fields are now modifiable.
* OpenFlow 1.5 extended registers are now supported.
* The OpenFlow 1.5 actset_output field is now supported.
with Docker, the wrapper script will be retired.
- Added support for DPDK Tunneling. VXLAN, GRE, and Geneve are supported
protocols. This is generic tunneling mechanism for userspace datapath.
- - Support for multicast snooping (IGMPv1 and IGMPv2)
+ - Support for multicast snooping (IGMPv1, IGMPv2 and IGMPv3)
- Support for Linux kernels up to 4.0.x
- The documentation now use the term 'destination' to mean one of syslog,
console or file for vlog logging instead of the previously used term
openvswitch.ko but built and loaded automatically as individual kernel
modules (vport-*.ko).
- Support for STT tunneling.
+ - Support to configure method (--syslog-method argument) that determines
+ how daemons will talk with syslog.
+ - Support for "ovs-appctl vlog/list-pattern" command that lets to query
+ logging message format for each destination.
+ - GRE64 and ipsec_gre64 tunnel protocol is deprecated and will be removed
+ from OVS v2.5 release.
