+Changes between GMP version 4.3.0 and 4.3.1
+
+ Bugs:
+ * Fixed bug in mpn_gcdext, affecting also mpz_gcdext and mpz_invert.
+ The bug could cause a cofactor to have a leading zero limb, which
+ could lead to crashes or miscomputation later on.
+ * Fixed some minor documentation issues.
+
+ Speedups:
+ * None.
+
+ Features:
+ * Workarounds for various issues with Mac OS X's build tools.
+ * Recognise more IBM "POWER" processor variants.
+
+
+Changes between GMP version 4.2.X and 4.3.0
+
+ Bugs:
+ * Fixed bug in mpz_perfect_power_p with recognition of negative perfect
+ powers that can be written both as an even and odd power.
+ * We might accidentally have added bugs since there is a large amount of
+ new code in this release.
+
+ Speedups:
+ * Vastly improved assembly code for x86-64 processors from AMD and Intel.
+ * Major improvements also for many other processor families, such as
+ Alpha, PowerPC, and Itanium.
+ * New sub-quadratic mpn_gcd and mpn_gcdext, as well as improved basecase
+ gcd code.
+ * The multiply FFT code has been slightly improved.
+ * Balanced multiplication now uses 4-way Toom in addition to schoolbook,
+ Karatsuba, 3-way Toom, and FFT.
+ * Unbalanced multiplication has been vastly improved.
+ * Improved schoolbook division by means of faster quotient approximation.
+ * Several new algorithms for division and mod by single limbs, giving
+ many-fold speedups.
+ * Improved nth root computations.
+ * The mpz_nextprime function uses sieving and is much faster.
+ * Countless minor tweaks.
+
+ Features:
+ * Updated support for fat binaries for x86_32 include current processors
+ * Lots of new mpn internal interfaces. Some of them will become public
+ in a future GMP release.
+ * Support for the 32-bit ABI under x86-apple-darwin.
+ * x86 CPU recognition code should now default better for future
+ processors.
+ * The experimental nails feature does not work in this release, but
+ it might be re-enabled in the future.
+
+ Misc:
+ * The gmp_version variable now always contains three parts. For this
+ release, it is "4.3.0".
+
+
+Changes between GMP version 4.2.3 and 4.2.4
+
+ Bugs:
+ * Fix bug with parsing exponent '+' sign in mpf.
+ * Fix an allocation bug in mpf_set_str, also affecting mpf_init_set_str, and
+ mpf_inp_str.
+
+ Speedups:
+ * None, except that proper processor recognition helps affected processors.
+
+ Features:
+ * Recognize new AMD processors.
+
+
+Changes between GMP version 4.2.2 and 4.2.3
+
+ Bugs:
+ * Fix x86 CPU recognition code to properly identify recent AMD and Intel
+ 64-bit processors.
+ * The >> operator of the C++ wrapper gmpxx.h now does floor rounding, not
+ truncation.
+ * Inline semantics now follow the C99 standard, and works with recent GCC
+ releases.
+ * C++ bitwise logical operations work for more types.
+ * For C++, gmp.h now includes cstdio, improving compiler compatibility.
+ * Bases > 36 now work properly in mpf_set_str.
+
+ Speedups:
+ * None, except that proper processor recognition helps affected processors.
+
+ Features:
+ * The allocation functions now detect overflow of the mpz_t type. This means
+ that overflow will now cause an abort, except when the allocation
+ computation itself overflows. (Such overflow can probably only happen in
+ powering functions; we will detect powering overflow in the future.)
+
+
+Changes between GMP version 4.2.1 and 4.2.2
+
+ * License is now LGPL version 3.
+
+ Bugs:
+ * Shared library numbers corrected for libcxx.

+ * Fix 32-bit ABI bug with Itanium assembly for popcount and hamdist.
+ * Fix assembly syntax problem for powerpc-ibm-aix with AIX native assembler.
+ * Fix problems with x86 --enable-fat, where the compiler where told to
+ generate code for the build machine, not plain i386 code as it should.
+ * Improved recognition of powerpc systems wrt Altivec/VMX capability.
+ * Misc minor fixes, mainly workarounds for compiler/assembler bugs.
+
+ Speedups:
+ * "Core 2" and Pentium 4 processors, running in 64-bit mode will get a
+ slight boost as they are now specifically recognized.
+
+ Features:
+ * New support for x86_64-solaris
+ * New, rudimentary support for x86-apple-darwin and x86_64-apple-darwin.

+ * New integer functions: mpz_combit, mpz_rootrem.
+ * gmp_printf etc new type "M" for mp_limb_t.
+ * gmp_scanf and friends now accept C99 hex floats.
+ * Numeric input and output can now be in bases up to 62.
+ * Comparisons mpz_cmp_d, mpz_cmpabs_d, mpf_cmp_d recognise infinities.
+ * Conversions mpz_get_d, mpq_get_d, mpf_get_d truncate towards zero,
+ previously their behaviour was unspecified.
+ * Fixes for overflow issues with operands >= 2^31 bits.
+
+ Caveats:
+ * mpfr is gone, and will from now on be released only separately. Please see
+ www.mpfr.org.

+
+
+Changes between GMP version 2.0 and 2.0.2
+
+* Many bug fixes.
+
+
+Changes between GMP version 1.3.2 and 2.0
+
+* Division routines in the mpz class have changed. There are three classes of
+ functions, that rounds the quotient to -infinity, 0, and +infinity,
+ respectively. The first class of functions have names that begin with
+ mpz_fdiv (f is short for floor), the second class' names begin with mpz_tdiv
+ (t is short for trunc), and the third class' names begin with mpz_cdiv (c is
+ short for ceil).
+
+ The old division routines beginning with mpz_m are similar to the new
+ mpz_fdiv, with the exception that some of the new functions return useful
+ values.
+
+ The old function names can still be used. All the old functions names will
+ now do floor division, not trunc division as some of them used to. This was
+ changed to make the functions more compatible with common mathematical
+ practice.
+
+ The mpz_mod and mpz_mod_ui functions now compute the mathematical mod
+ function. I.e., the sign of the 2nd argument is ignored.
+
+* The mpq assignment functions do not canonicalize their results. A new
+ function, mpq_canonicalize must be called by the user if the result is not
+ known to be canonical.
+* The mpn functions are now documented. These functions are intended for
+ very time critical applications, or applications that need full control over
+ memory allocation. Note that the mpn interface is irregular and hard to
+ use.
+* New functions for arbitrary precision floating point arithmetic. Names
+ begin with `mpf_'. Associated type mpf_t.
+* New and improved mpz functions, including much faster GCD, fast exact
+ division (mpz_divexact), bit scan (mpz_scan0 and mpz_scan1), and number
+ theoretical functions like Jacobi (mpz_jacobi) and multiplicative inverse
+ (mpz_invert).
+* New variable types (mpz_t and mpq_t) are available that makes syntax of
+ mpz and mpq calls nicer (no need for & before variables). The MP_INT and
+ MP_RAT types are still available for compatibility.
+* Uses GNU configure. This makes it possible to choose target architecture
+ and CPU variant, and to compile into a separate object directory.
+* Carefully optimized assembly for important inner loops. Support for DEC
+ Alpha, Amd 29000, HPPA 1.0 and 1.1, Intel Pentium and generic x86, Intel
+ i960, Motorola MC68000, MC68020, MC88100, and MC88110, Motorola/IBM
+ PowerPC, National NS32000, IBM POWER, MIPS R3000, R4000, SPARCv7,
+ SuperSPARC, generic SPARCv8, and DEC VAX. Some support also for ARM,
+ Clipper, IBM ROMP (RT), and Pyramid AP/XP.
+* Faster. Thanks to the assembler code, new algorithms, and general tuning.
+ In particular, the speed on machines without GCC is improved.
+* Support for machines without alloca.
+* Now under the LGPL.
+
+INCOMPATIBILITIES BETWEEN GMP 1 AND GMP 2
+
+* mpq assignment functions do not canonicalize their results.
+* mpz division functions round differently.
+* mpz mod functions now really compute mod.
+* mpz_powm and mpz_powm_ui now really use mod for reduction.
