+* **Added extendable bucket feature to hash library (rte_hash).**
+
+  This new “extendable bucket” feature provides 100% insertion guarantee to
+  the capacity specified by the user by extending hash table with extra
+  buckets when needed to accommodate the unlikely event of intensive hash
+  collisions.  In addition, the internal hashing algorithm was changed to use
+  partial-key hashing to improve memory efficiency and lookup performance.
