Changes between 6.0.0 and 6.0.0a:
Not documented.
Changes between GMP version 5.1.* and 6.0.0
BUGS FIXED
* The function mpz_invert now considers any number invertible in Z/1Z.
* The mpn multiply code now handles operands of more than 2^31 limbs
correctly. (Note however that the mpz code is limited to 2^32 bits on
32-bit hosts and 2^37 bits on 64-bit hosts.)
* Contains all fixes from release 5.1.3.
SPEEDUPS
* Plain division of large operands is faster and more monotonous in operand
size.
* Major speedup for ARM, in particular ARM Cortex-A15, thanks to improved
assembly.
* Major speedup for SPARC T4/T5 and speedup also for T3, thanks to a lot of
new assembly.
* Speedup for Intel Sandy Bridge, Ivy Bridge, Haswell, thanks to rewritten
and vastly expanded assembly support. Speedup also for the older Core 2
and Nehalem.
* Faster mixed arithmetic between mpq_class and double.
* With g++, optimise more operations when one argument is a simple constant.
FEATURES
* Support for new Intel and AMD CPUs.
* Support for ARM64 alias Aarch64 alias ARMv8.
* New public functions mpn_sec_mul and mpn_sec_sqr, implementing side-channel
silent multiplication and squaring.
* New public functions mpn_sec_div_qr and mpn_sec_div_r, implementing
side-channel silent division.
* New public functions mpn_cnd_add_n and mpn_cnd_sub_n. Side-channel silent
conditional addition and subtraction.
* New public function mpn_sec_powm, implementing side-channel silent modexp.
* New public function mpn_sec_invert, implementing side-channel silent
modular inversion.
* Better support for applications which use the mpz_t type, but nevertheless
need to call some of the lower-level mpn functions. See the documentation
for mpz_limbs_read and related functions.
