2.03
 - Needs version 2.4.0 (or later) of the mpfr library.
 - Add the following functions (new in mpfr-2.4.0):
   Rmpfr_add_d, Rmpfr_sub_d, Rmpfr_d_sub Rmpfr_mul_d, Rmpfr_div_d,
   Rmpfr_d_div, Rmpfr_rec_sqrt, Rmpfr_sinh_cosh, Rmpfr_li2, Rmpfr_zeta_ui,
   Rmpfr_modf, Rmpfr_fmod, Rmpfr_printf, Rmpfr_fprintf, Rmpfr_sprintf,
   Rmpfr_sprintf_ret
 - Fix overload_sqrt() so that it returns a NaN for negative operands
   instead of croaking, as was originally the case.
 - Remove (the need for) INLINE.h
 - Add RMPFR_PREC_MIN and RMPFR_PREC_MAX.
 - Add Rmpfr_sum, Rmpfr_get_d_2exp, Rmpfr_get_ld_2exp, Rmpfr_dim,
   Rmpfr_fits_ushort_p, Rmpfr_fits_sshort_p, Rmpfr_fits_uint_p,
   Rmpfr_fits_sint_p, Rmpfr_fits_uintmax_p, Rmpfr_fits_intmax_p,
   Rmpfr_fits_IV_p, Rmpfr_fits_UV_p Rmpfr_add_si Rmpfr_get_UV
   Rmpfr_get_IV Rmpfr_get_NV 

2.02
 - Add TRmpfr_out_str/TRmpfr_inp_str (which wraps mpfr_out_str/mpfr_inp_str
   more Truly than Rmpfr_out_str/Rmpfr_inp_str).
 - Rmpfr_out_str now has the option to take a prefix string.
 - Remove the tests in the Makefile.PL that test for the presence of
   a suitable compiler, GMP library and MPFR library.

2.01
 - Needs version 2.3.0 (or later) of the mpfr library.
 - Add Rmpfr_j0, Rmpfr_j1, Rmpfr_jn, Rmpfr_y0, Rmpfr_y1,
   Rmpfr_yn, Rmpfr_lgamma, Rmpfr_remainder, Rmpfr_remquo,
   Rmpfr_fms, Rmpfr_signbit, Rmpfr_setsign, and
   Rmpfr_copysign(all new in 2.3.0). Add also Rmpfr_get_patches
   (documented for the first time in 2.3.0).
 - Add Rmpfr_init_set_ld.
 - Add Rmpfr_deref2 to the list of exportable functions, and 
   document it's usage in the POD section.
 - Rmpfr_deref2 now has the mpfr library allocate (and free) memory
   for the mantissa.
 - Add Rmpfr_hypot (previously missed).
 - Rmpfr_out_str now takes an optional fifth argument (a string that
   will be appended to the mpfr_out_str output). And the output 
   buffer is now flushed each time Rmpfr_out_str is called.
 - Rewrite new() - to make it a little tidier.
 - Add Rmpfr_set_uj and Rmpfr_set_uj_2exp to @EXPORT_TAGS. (Previously
   overlooked.)
 - Add Rmpfr_integer_string() - mainly to provide a simple means of
   getting 'sj' and 'uj' values on a 64-bit perl where the MPFR 
   library does not support mpfr_get_uj and mpfr_get_sj functions -
   which happens with libraries built with Microsoft Compilers.
 - Fix the rendering of Inf and NaN values. (Now matches the 
   mpfr_out_str output for Inf and NaN.)
 - Change the format returned by Rmpfr_get_str. (Hence the output of
   Rmpfr_get_string and Math::MPFR::overload_string have changed
   from earlier versions of Math::MPFR.) 
 - Fix some of the overloaded subroutines as regards their handling
   of NaN.

1.11
 - Fix bug in Rmpfr_get_str. (Sometimes printed out one less digit
   than it ought.)
 - Remove mpfr.info from distribution. Refer instead to:
   http://www.mpfr.org/mpfr-current/mpfr.html
 - Have 'make clean' remove comp.exe, check.exe and version.exe.
 - Add support for perls built with -Duselongdouble
   (Rmpfr_*_ld functions, except Rmpfr_init_set_ld() which is not
    available in unpatched 2.2.1).
 - Add Rmpfr_cmp_d, Rmpfr_exp10 and the Rmpfr_*_uj functions (which
   had somehow been earlier overlooked).
 - Fix handling of unsigned long longs on perls built with -Duse64bitint.
 - Allow assignment of mpz, mpq, and mpf types using new()

1.10
 - No longer assign Exporter and DynaLoader to @Math::MPFR::ISA.
 - Add support for perls built with -Duse64bitint. This involved the
   inclusion of the Rmpfr_set_sj, Rmpfr_set_sj_2exp and Rmpfr_get_sj
   functions - as well as some alterations to the overload subs.

1.09
 - Changes to the format returned by Rmpfr_get_str and overload_string.
 - Add a new() method/function for creation of mpfr_t objects.
 - Fix Rmpfr_out_str() and Rmpfr_inp_str() - were segfaulting with
   MS compilers.


1.08
 - As of this version, MPFR-2.2.x is required.
 - Add new functions made available with the release of MPFR-2.2.0:
   Rmpfr_set_overflow Rmpfr_set_underflow Rmpfr_set_inexflag
   Rmpfr_set_erangeflag Rmpfr_set_nanflag Rmpfr_erfc Rmpfr_atan2 
   Rmpfr_pow_z Rmpfr_subnormalize Rmpfr_const_catalan Rmpfr_sec 
   Rmpfr_csc Rmpfr_cot Rmpfr_root Rmpfr_eint Rmpfr_get_f Rmpfr_sech
   Rmpfr_csch Rmpfr_coth Rmpfr_lngamma RMPFR_VERSION_NUM
 - Add constants (actually implemented as subroutines):
   MPFR_VERSION MPFR_VERSION_MAJOR MPFR_VERSION_MINOR
   MPFR_VERSION_PATCHLEVEL MPFR_VERSION_STRING
 - Remove Rmpfr_add_one_ulp and Rmpfr_sub_one_ulp (no longer supported
   by the MPFR library).
 - Redefine '__gmpfr_default_rounding_mode' in MPFR.xs as it's no 
   longer in mpfr.h. (Been moved to mpfr-impl.h which I don't want to
   include.)
 - Rewrite of overload_atan2 - now that mpfr_atan2 is available in 
   MPFR-2.2.0. (Also fixes a bug in overload_atan2).

1.07
 - New() was allocating more memory than necessary in many instances.
   Rewrote the XS code (in those instances) to fix that.
 - Add Rmpfr_strtofr


1.06
 - Modify the Makefile.PL checks added in version 1.05 to cater for
   those building with a Microsoft compiler
 - Alter Rmpfr_set_str and Rmpfr_init_set_str so that a base of 0
   can be specified - in which case the base is determined from the
   input string
 - Added the following functions:
   Rmpfr_get_ui Rmpfr_get_si Rmpfr_fits_ulong_p Rmpfr_fits_slong_p
 - Fix a bug in 'Rmpfr_deref2()' - used by 'overload_print()'
 - Provide more complete testing with 4 new test files - namely
   test4.t, trig.t, set_str.t and exceptions.t.


1.05
 - Add some checks to Makefile.PL to ensure that anyone trying to
   build this module has an up-to-date MPFR library. This is mainly
   an attempt to stop cpan testers who don't have an up-to-date MPFR
   from testing the module and subsequently reporting "FAIL" or "NA".


1.04
 - Math::MPFR-1.04 to 1.07 require MPFR-2.1.x.
 - Added the following functions, not available with versions earlier
   than 2.1.0 :
   Rmpfr_set_ui_2exp Rmpfr_set_si_2exp Rmpfr_get_z Rmpfr_si_sub 
   Rmpfr_sub_si Rmpfr_mul_si Rmpfr_si_div Rmpfr_div_si Rmpfr_sqr
   Rmpfr_cmp_z Rmpfr_cmp_q Rmpfr_cmp_f Rmpfr_zero_p Rmpfr_free_cache
   Rmpfr_get_version Rmpfr_get_emin_min Rmpfr_get_emin_max 
   Rmpfr_get_emax_min Rmpfr_get_emax_max Rmpfr_clear_erangeflag
   Rmpfr_erangeflag_p Rmpfr_rint_round Rmpfr_rint_trunc

   with changes to the MPFR library.
