 -------------------
+* Significant ABI changes are planned for struct rte_mbuf, struct rte_kni_mbuf, and several PKT_RX_ flags will be removed, to support unified packet type from release 2.1. The upcoming release 2.1 will have those changes for static libraries only, while have no change for shared libraries by default. Those changes will be taken effect for shared libraries from release 2.2. There is no backward compatibility planned from release 2.2. All binaries will need to be rebuilt from release 2.2.
