++v2.16.3 - 08 Apr 2022
++---------------------
++ - Bug fixes
++ - 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.
++ - Python:
++ * For SSL support, the use of the pyOpenSSL library has been replaced
++ with the native 'ssl' module.
