+* **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.
