+Changes between GMP version 5.1.* and 5.2.0
+
+ 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.
+
+ MISC
+ * This release will not work on NetBSD 5.x, FreeBSD 7.x, 8.x or 9 series
+ before 9.3. The reason is that the m4 command is not correctly
+ implemented. (Workaround: Use an older GMP release, or install GNU m4 from
+ /usr/ports and tell GMP to use it.)
+
+ * This release will not build properly on FreeBSD/amd64 before version 10
+ using the 32-bit ABI (once a working m4 is installed). The reason is
+ broken limits.h. (Workaround: Use an older GMP release if using the 32-bit
+ ABI on these FreeBSD releases is important.)
+
+ * This release will not work reliably on FreeBSD 10.0 for i386 or amd64 using
+ the 32-bit ABI. The reason is bugs in the compiler 'clang'. Depending on
+ CPU-dependent compiler flags, GMP may or may not be miscompiled in a
+ particular build. (Workaround: Compiling gcc from /usr/ports should work,
+ except that gcc circularly depends on GMP; we have not been able to test
+ that workaround due to FreeBSD 10.0 bugs affecting its ability to run under
+ KVM and Xen.)
+
+ * This release will not compile on FreeBSD before version 10 for i386,
+ targeting any modern AMD processor. The reason is bugs in the old gcc
+ bundled with FreeBSD. (Workaround: install a less obsolete gcc from
+ /usr/ports and tell GMP to use it, or override the -march=amdfam10
+ GMP configure command line argument.)
+
+
Changes between GMP version 5.1.2 and 5.1.3
BUGS FIXED
MISC
* None.
+
Changes between GMP version 5.1.1 and 5.1.2
BUGS FIXED
* A bug in mpz_powm_ui triggered by base arguments of at least 15000 decimal
digits or mod arguments of at least 7500 decimal digits has been fixed.
- * A AMD Bulldozer specific bug affecting the 64-bit Windows ABI has been
+ * An AMD Bulldozer specific bug affecting the 64-bit Windows ABI has been
fixed. This bug was in a key function (mpn_mul_1) and made both Bulldozer
specific builds and fat builds run on Bulldozer completely non-functional.
This is more consistent with other powerpc systems.
* The coverage of the testsuite has been improved, using the lcov tool. See
- also http://gmplib.org/devel/lcov/.
+ also https://gmplib.org/devel/lcov/.
* It is now possible to compile GMP using a C++ compiler.
Features:
* New support for x86_64-solaris
* New, rudimentary support for x86-apple-darwin and x86_64-apple-darwin.
