-  * gmp_snprintf now correctly reports an error (returns -1) when
-    snprintf does.

-  * conversion to double is now more robust even if the configuration

   FEATURES
   * New C++ functions factorial, primorial and fibonacci for mpz_class.
 
+  * Functions to detect primality now substitute 24 Miller-Rabin iterations
+    with the BPSW test.
+
   * Mini-GMP: new functions mpz_2fac_ui and mpz_mfac_uiui.
 
-  * Mini-GMP: mpz_sizeinbase, mpz_get_str, and mpz_set_str now support
-    bases up to 62.
+  * Mini-GMP: mpz_sizeinbase, mpz_get_str, and mpz_set_str now support bases up
+    to 62.
 
   * Mini-GMP: added support for the mpq_t layer.
 
-  * Functions to detect primality now substitute 24 Miller-Rabin
-    iterations with the BPSW test.
+  SPEEDUPS
+  * Major speedup for AMD Ryzen and Epyc through extensive set of assembly
+    code.
 
-  SPEEDUPS
-  * The n-over-k function have been reimplemented for great
-    speedups for large operands handled by mpz_bin_ui .
+  * Speedup for IBM POWER9 through assembly code making use of new madd
+    instruction.
+
+  * The n-over-k function mpz_bin_ui has been reimplemented for great speedups
+    for large operands.
+
+  * Speedup for gcd for small and medium size operands.
 
   MISC
   * Internal representation of the mpz_t variables now supports lazy

   * Small improvements and better coverage for the test suite.
 
+  * mpn_mul no longer diverts to mpn_sqr, users should call mpn_sqr directly
+    when applicable.
