+Changes between MP version 3.1 and 3.1.1
+
+* Bug fixes for division (rare), mpf_get_str, FFT, and miscellaneous minor
+  things.
+
+Changes between MP version 3.0 and 3.1
+
+* Bug fixes.
+* Improved `make check' running more tests.
+* Tuned algorithm cutoff points for many machines.  This will improve speed for
+  a lot of operations, in some cases by a large amount.
+* Major speed improvments: Alpha 21264.
+* Some speed improvments: Cray vector computers, AMD K6 and Athlon, Intel P5
+  and Pentium Pro/II/III.
+* The mpf_get_prec function now works as it did in GMP 2.
+* New utilities for auto-tuning and speed measuring.
+* Multiplication now optionally uses FFT for very large operands.  (To enable
+  it, pass --enable-fft to configure.)
+* Support for new systems: Solaris running on x86, FreeBSD 5, HP-UX 11, Cray
+  vector computers, Rhapsody, Nextstep/Openstep, MacOS.
+* Support for shared libraries on 32-bit HPPA.
+* New integer functions: mpz_mul_si, mpz_odd_p, mpz_even_p.

+* New float functions: mpf_swap.
+* New mpn functions: mpn_divexact_by3c, mpn_tdiv_qr.
+* New EXPERIMENTAL function layer for accurate floating-point arithmetic, mpfr.
+  To try it, pass --enable-mpfr to configure.  See the mpfr subdirectory for
+  more information; it is not documented in the main GMP manual.
+
+Changes between MP version 3.0 and 3.0.1
+
+* Memory leaks in gmp_randinit and mpz_probab_prime_p fixed.
+* Documentation for gmp_randinit fixed.  Misc documentation errors fixed.
+
+Changes between MP version 2.0 and 3.0
+
+* Source level compatibility with past releases (except mpn_gcd).
+* Bug fixes.
+* Much improved speed thanks to both host independent and host dependent
+  optimizations.
+* Switch to autoconf/automake/libtool.
+* Support for building libgmp as a shared library.
+* Multiplication and squaring using 3-way Toom-Cook.
+* Division using the Burnikel-Ziegler method.
+* New functions computing binomial coefficients: mpz_bin_ui, mpz_bin_uiui.
+* New function computing Fibonacci numbers: mpz_fib_ui.
+* New random number generators: mpf_urandomb, mpz_rrandomb, mpz_urandomb,
+  mpz_urandomm, gmp_randclear, gmp_randinit, gmp_randinit_lc_2exp, gmp_randseed, 
+  gmp_randseed_ui.
+* New function for quickly extracting limbs: mpz_getlimbn.
+* New functions performing integer size tests: mpz_fits_sint_p,
+  mpz_fits_slong_p, mpz_fits_sshort_p, mpz_fits_uint_p, mpz_fits_ulong_p,
+  mpz_fits_ushort_p.
+* New mpf functions: mpf_ceil, mpf_floor, mpf_pow_ui, mpf_trunc.
+* New mpq function: mpq_set_d.
+* New mpz functions: mpz_addmul_ui, mpz_cmpabs, mpz_cmpabs_ui, mpz_lcm,
+  mpz_nextprime, mpz_perfect_power_p, mpz_remove, mpz_root, mpz_swap,
+  mpz_tdiv_ui, mpz_tstbit, mpz_xor.
+* New mpn function: mpn_divexact_by3.
+* New CPU support: DEC Alpha 21264, AMD K6 and Athlon, HPPA 2.0 and 64,
+  Intel Pentium Pro and Pentium-II/III, Sparc 64, PowerPC 64.
+* Almost 10 times faster mpz_invert and mpn_gcdext.
+* The interface of mpn_gcd has changed.
+* Better support for MIPS R4x000 and R5000 under Irix 6.
+* Improved support for SPARCv8 and SPARCv9 processors.
+
+Changes between MP version 2.0 and 2.0.2
+
+* Many bug fixes.
+
+Changes between MP 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.
