 - Change module name from 'Math::GnuMPfr' to 'Math::MPFR'.

1.01
 - Eradicate segfault that was occurring when 'overload_add',
   'overload_sub', 'overload_mul', 'overload_div' and 'overload_pow'
   croaked due to invalid argument(s).

1.02
 - Make overloading work with strings.
 - Add 'Rmpfr_dump'.

1.03
 - Replace 'SvROK()' with 'sv_isobject()' in the overload functions.
 - Make 'get_refcnt()' and 'get_package_name()' non-exportable.

1.04
 - Built against MPFR-2.1.0.
 - 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_erangeflag_p Rmpfr_rint_round Rmpfr_rint_trunc
   Rmpfr_rint_ceil Rmpfr_rint_floor

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".
