 +v2.15.4 - xx xxx xxxx
 +---------------------
++   - libopenvswitch API change:
++     * To fix the Undefined Behavior issue causing the compiler to incorrectly
++       optimize important parts of code, container iteration macros (e.g.,
++       LIST_FOR_EACH) have been re-implemented in a UB-safe way.
++     * Backwards compatibility has mostly been preserved, however the
++       user-provided pointer is now set to NULL after the loop (unless it
++       exited via "break;")
++     * Users of libopenvswitch will need to double-check the use of such loop
++       macros before compiling with a new version.
++     * Since the change is limited to the definitions within the headers, the
++       ABI is not affected.
 +   - DPDK:
 +     * OVS validated with DPDK 20.11.4. It is recommended to use this version
 +       until further releases.
