      =========================================================
 
+* **Updated the EAL Pseudo-random Number Generator.**
+
+  The lrand48()-based rte_rand() function is replaced with a
+  DPDK-native combined Linear Feedback Shift Register (LFSR)
+  pseudo-random number generator (PRNG).
+
+  This new PRNG implementation is multi-thread safe, provides
+  higher-quality pseudo-random numbers (including full 64 bit
+  support) and improved performance.
+
+  In addition, <rte_random.h> is extended with a new function
+  rte_rand_max() which supplies unbiased, bounded pseudo-random
+  numbers.
