Changes from versions 2.4.* to version 3.0:
- MPFR 3.0 is binary incompatible with previous versions but (almost)
  API compatible. More precisely the obsolete functions mpfr_random
  and mpfr_random2 have been removed, and the return type of the
  functions mpfr_get_f and mpfr_get_z is now int instead of void.
  In practice, this should not break any existing code.
- MPFR is now distributed under the GNU Lesser General Public License
  version 3 or later (LGPL v3+).
- Rounding modes GMP_RNDx are now MPFR_RNDx (GMP_RNDx kept for
  compatibility).
- A new rounding mode (MPFR_RNDA) is available to round away from zero.
- The rounding mode type is now mpfr_rnd_t (as in previous versions,
  both mpfr_rnd_t and mp_rnd_t are accepted, but mp_rnd_t may be
  removed in the future).
- The precision type is now mpfr_prec_t (as in previous versions, both
  mpfr_prec_t and mp_prec_t are accepted, but mp_prec_t may be removed
  in the future) and it is now signed (it was unsigned in MPFR 2.*, but
  this was not documented). In practice, this change should not affect
  existing code that assumed nothing on the precision type.
- MPFR now has its own exponent type mpfr_exp_t, which is currently
  the same as GMP's mp_exp_t.
- Functions mpfr_random and mpfr_random2 have been removed.
- mpfr_get_f and mpfr_get_z now return a ternary value.
- mpfr_strtofr now accepts bases from 37 to 62.
- New functions mpfr_buildopt_tls_p and mpfr_buildopt_decimal_p giving
  information about options used at MPFR build time.
- New function mpfr_regular_p.
- New function mpfr_set_zero.
- New function mpfr_digamma.
- New function mpfr_ai (incomplete, experimental).
- New functions mpfr_set_flt and mpfr_get_flt to convert from/to the
  float type.
- New function mpfr_urandom.
- New function mpfr_set_z_2exp (companion to mpfr_get_z_2exp, which
  was renamed from mpfr_get_z_exp in previous versions).
- Speed improvement for large operands in the trigonometric functions
  (mpfr_sin, mpfr_cos, mpfr_tan, mpfr_sin_cos): speedup of about 2.5
  for 10^5 digits, of about 5 for 10^6 digits.
- Speed improvement for large operands of the inverse trigonometric
  functions (arcsin, arccos, arctan): about 2 for 10^3 digits, up to
  2.7 for 10^6 digits.
- Some documentation files are installed in $docdir.
- The configure script recognizes some extra "long double" formats
  (double big endian, double little endian, double-double big endian).
- MPFR manual: added "API Compatibility" section.
- Bug fixes.

Please send success and failure reports with "./config.guess" output
to <mpfr at loria.fr>.

If no problems are found, GNU MPFR 3.0.0 should be released
around 2010-06-07.
