+   - ovs-ofctl has a new '--bundle' option that makes the flow mod commands
+     ('add-flow', 'add-flows', 'mod-flows', 'del-flows', and 'replace-flows')
+     use an OpenFlow 1.4 bundle to operate the modifications as a single
+     transaction.  If any of the flow mods in a transaction fail, none of
+     them are executed.
+   - ovs-ofctl 'add-flow' and 'add-flows' commands now accept arbitrary flow
+     mods as an input by allowing the flow specification to start with an
+     explicit 'add', 'modify', 'modify_strict', 'delete', or 'delete_strict'
+     keyword.  A missing keyword is treated as 'add', so this is fully
+     backwards compatible.  With the new '--bundle' option all the flow mods
+     are executed as a single transaction using the new OpenFlow 1.4 bundles
+     support.
