+Changes between GMP version 6.1.* and 6.2.0
+
+ BUGS FIXED
+ * gmp_snprintf now correctly reports an error (returns -1) when snprintf
+ does.
+
+ * Conversion to double is now more robust even if the configuration process
+ does not recognize the float format.
+
+ * mpz_powm could return a not completely normalised value, when the
+ exponent was 1 and the base < 0.
+
+ * mpf_set_str could create invalid mpf_t variables for input strings with
+ many leading zeros.
+
+ FEATURES
+ * New C++ functions factorial, primorial and fibonacci for mpz_class.
+
+ * Functions to detect primality now substitute the first 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: added support for the mpq_t layer.
+
+ * MIPS r6 cores are now supported.
+
+ SPEEDUPS
+ * Major speedup for AMD Ryzen and Epyc thanks to an extensive set of assembly
+ code.
+
+ * Major speedup for IBM POWER9 thanks to assembly code making use of new madd
+ instruction.
+
+ * Speedup for 64-bit ARM CPUs thanks to new/improved assembly code.
+
+ * The n-over-k function mpz_bin_ui has been reimplemented for great speedups
+ for large operands.
+
+ * Speedup for the worst case of mpz_perfect_power_p.
+
+ * Speedup for gcd for small and medium size operands.
+
+ * Speedup for really huge multiplies thanks to much larger FFT tables.
+
+ MISC
+ * Internal representation of the mpz_t variables now supports lazy
+ allocation; memory is allocated only when a value is stored.
+
+ * Small improvements and better coverage for the test suite.
+
+ * The tune/speed program can measure some more functions.
+
+ * The low-level function mpn_mul no longer diverts to mpn_sqr, users should
+ call mpn_sqr directly when applicable.
+
+ * New installed files gmp.pc and gmpxx.pc, for use with pkg-config.
