3.0

• Corresponding to release of mpfr-3.0.0. (Still needs only 2.4.0, but 3.0.0 needed to take advantage of all features.)
• Add MPFR_ rounding modes (including MPFR_RNDA for builds against mpfr-3.0.0)
• Add Rmpfr_buildopt_tls_p() and Rmpfr_buildopt_decimal_p() (mpfr-3.0.0 only)
• Add the following functions, specific to mpfr-3.0.0: Rmpfr_regular_p, Rmpfr_set_zero, Rmpfr_digamma, Rmpfr_ai, Rmpfr_set_flt, Rmpfr_get_flt, Rmpfr_urandom and Rmpfr_setz2exp.
• Add Rmpfr_getz2exp (mpfr_getzexp is now renamed to mpfr_getz2exp).
• Add gmp_randstate_t to the Math::MPFR typemap.
• Change handling of NaNs (wrt overloaded comparison operators). The spaceship operator now returns undef when NaNs are involved (more in keeping with perl behaviour), and the erange flag is now set whenever a comparison involving NaNs is performed (more in keeping with the mpfr library behaviour). This is irrespective of whether the NaN is a Math::MPFR object or a perl NV. The other comparison operators now also set the erange flag when a NaN is involved (for compatibility with the mpfr library).
• Add Rmpfr_snprintf and Rmpfr_snprintf_ret.
• Add Rmpfr_inits, Rmpfr_inits2 and Rmpfr_clears functions.
• The overload_copy sub now preserves the precision of the copied object (instead of taking on default precision). 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, Rmpfrdsub Rmpfr_mul_d, Rmpfr_div_d, Rmpfrddiv, 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_getd2exp, 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 Rmpfrinit_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.

• Add 'Math::MPFR::gmp_v' (not exportable).

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).
