- GMP 6.3.0
* A possible overflow of type int is avoided for mpz_cmp on huge operands.
* A possible error condition when a malformed file is read with mpz_inp_raw
is now correctly handled.
* New public function mpz_prevprime, companion of the existing mpz_nextprime.
* New documented pointer types mpz_ptr, mpz_srcptr, and similar for other
GMP types. Refer to the manual for full list and suggested usage. These
types have been present in gmp.h at least since GMP-4.0, but previously
not advertised to users.
* Support for 64-bit Arm under Macos.
* Support for the loongarch64 CPU family.
* Support for building with LTO, link-time optimisations.
* New special code for base = 2 in mpz_powm reduces the average time for
the functions that test primality.
* Speedup for the function mpz_nextprime on large operands.
* Speedup for multiplications (some sizes only) thanks to new internal
functions to compute small negacyclic products.
* Special assembly code for IBM z13 and later "mainframe" CPUs, resulting
in a huge speedup.
* Improved assembly for several 64-bit x86 CPUs, Risc-V, 64-bit Arm.
- Removed gmp-6.2.1-CVE-2021-43618.patch which is included in the
new release.
