- DPDK:
* New option 'other_config:dpdk-socket-limit' to limit amount of
hugepage memory that can be used by DPDK.
+ * Add support for vHost Post-copy Live Migration (experimental).
+ * OVS validated with DPDK 18.11.2 which is the new minimal supported
+ version.
+ * DPDK 18.11.1 and lower is no longer supported.
+ * New option 'tx-retries-max' to set the maximum amount of vhost tx
+ retries that can be made.
- OpenFlow:
+ * All features required by OpenFlow 1.5 are now implemented, so
+ ovs-vswitchd now enables OpenFlow 1.5 by default (in addition to
+ OpenFlow 1.0 to 1.4).

* New action "check_pkt_larger".

+ datapath regardless of '--cleanup' option. Use '--cleanup' to remove
+ internal ports too.
+ * Removed experimental tag for SMC cache.

- OVSDB:
