   * The mpz_powm_sec function now uses side-channel silent division for
     converting into Montgomery residues.
 
+  * The fat binary mechanism is now more robust in its CPU recognition.

   * In C++, the conversions mpq_class->mpz_class, mpf_class->mpz_class and
     mpf_class->mpq_class are now explicit.
 
-  * Includes "mini-gmp", a small, portable, but less efficient,
-    implementation of a subset of GMP's mpn and mpz interfaces. Used
-    in GMP bootstrap, but it can also be bundled with applications as
-    a fallback when the real GMP library is unavailable.

   * The ABIs under AIX are no longer called aix32 and aix64, but mode64 and 32.
     This is more consistent with other powerpc systems.

 Calling this function instead of @code{mpz_init} or @code{mpz_inits} is never
