+Post-v2.15.0
+---------------------
+ - In ovs-vsctl and vtep-ctl, the "find" command now accept new
+ operators {in} and {not-in}.
+
+
+v2.15.0 - xx xxx xxxx
+---------------------
+ - OVSDB:
+ * Changed format in which ovsdb transactions are stored in database files.
+ Now each transaction contains diff of data instead of the whole new
+ value of a column.
+ New ovsdb-server process will be able to read old database format, but
+ old processes will *fail* to read database created by the new one.
+ For cluster and active-backup service models follow upgrade instructions
+ in 'Upgrading from version 2.14 and earlier to 2.15 and later' section
+ of ovsdb(7).
+ * New unixctl command 'ovsdb-server/get-db-storage-status' to show the
+ status of the storage that's backing a database.
+ * New unixctl command 'ovsdb-server/memory-trim-on-compaction on|off'.
+ If turned on, ovsdb-server will try to reclaim all the unused memory
+ after every DB compaction back to OS. Disabled by default.
+ * Maximum backlog on RAFT connections limited to 500 messages or 4GB.
+ Once threshold reached, connection is dropped (and re-established).
+ Use the 'cluster/set-backlog-threshold' command to change limits.
+ - DPDK:
+ * Removed support for vhost-user dequeue zero-copy.
+ * Add support for DPDK 20.11.
+ - Userspace datapath:
+ * Add the 'pmd' option to "ovs-appctl dpctl/dump-flows", which
+ restricts a flow dump to a single PMD thread if set.
+ * New 'options:dpdk-vf-mac' field for DPDK interface of VF ports,
+ that allows configuring the MAC address of a VF representor.
+ * Add generic IP protocol support to conntrack. With this change, all
+ none UDP, TCP, and ICMP traffic will be treated as general L3
+ traffic, i.e. using 3 tupples.
+ * Add parameters 'pmd-auto-lb-load-threshold' and
+ 'pmd-auto-lb-improvement-threshold' to configure PMD auto load balance
+ behaviour.
+ - The environment variable OVS_UNBOUND_CONF, if set, is now used
+ as the DNS resolver's (unbound) configuration file.
+ - Linux datapath:
+ * Support for kernel versions up to 5.8.x.
+ - Terminology:
+ * The terms "master" and "slave" have been replaced by "primary" and
+ "secondary", respectively, for OpenFlow connection roles.
+ * The term "slave" has been replaced by "member", for bonds, LACP, and
+ OpenFlow bundle actions.
+ - Support for GitHub Actions based continuous integration builds has been
+ added.
+ - Bareudp Tunnel
+ * Bareudp device support is present in linux kernel from version 5.7
+ * Kernel bareudp device is not backported to ovs tree.
+ * Userspace datapath support is not added
+ - ovs-dpctl and 'ovs-appctl dpctl/':
+ * New commands '{add,mod,del}-flows' where added, which allow adding,
+ deleting, or modifying flows based on information read from a file.
+ - IPsec:
+ * Add option '--no-cleanup' to allow ovs-monitor-ipsec to stop without
+ tearing down IPsec tunnels.
+ * Add option '--no-restart-ike-daemon' to allow ovs-monitor-ipsec to start
+ without restarting ipsec daemon.
+ - Building the Linux kernel module from the OVS source tree is deprecated
+ * Support for the Linux kernel is capped at version 5.8
+ * Only bug fixes for the Linux OOT kernel module will be accepted.
+ * The Linux kernel module will be fully removed from the OVS source tree
+ in OVS branch 2.18
