0.12
  - approx()imate test 3 result of pow.t if it fails initially.
  - run try.exe to check for undefined references that don't show up until
    runtime.
  - add more diagnostics to nan_pow.t for failing nan**0 tests.
  - tweaks to cmp.t to try to fix or better understand some strange failures on FreeBSD.

 0.11
  - Add extra checks, workarounds, tests wrt (the possibly unimplemented)
    isnanl(), nanl() and signbitl().


 0.10
  - Fix checking for nan**0 bug.
  - Modify t/nan_pow.t and t/overload.t to accommodate nan**0 bug.
  - Check for (and workaround) absence of isnanl(). (Assume that if isnanl
    is missing then so is nanl - and work around that, too.)

 0.09
  - Work around bug on some compilers that has nan**0 is NaN.
  - Allow less stringent checking on cbrt() calculations that should return
    an integer value. (This accommodates a minor, but nonetheless annoying,
    bug with some libc versions.)

 0.08
  - Provide more float.h and math.h constants.

 0.07
  - Add math library functions.
  - Add ld_bytes function.
  - Allow overloading of UV, IV, NV and PV types.
  - Remove support for *signed* NaN.

 0.06
  - Add -DOLDPERL capability to Makefile.PL
  - Add LD_LDBL_MANT_DIG and LD_DBL_MANT_DIG

 0.05
  - Provide LD_DBL_DIG LD_LDBL_DIG ld_min_inter_prec ld_max_orig_len
    ld_min_inter_base and ld_max_orig_base functions.
  - Define PERL_NO_GET_CONTEXT.
  - Add metadata to Makefile.PL.

 0.04
  - Use float.h's LDBL_DIG to set the initial value of _DIGITS in LongDouble.xs.
  - Add _LDBL_DIG XSub so that we can see the value of float.h's LDBL_DIG.
  - Amend t/prec.t to work with powerpc64 (where long double has 106 bits of
    precision).

 0.03
  - Fix LDtoLD and STRtoLD documentation.
  - Alter the way that strEQ gets hold of HvNAME(SvSTASH(SvRV(sv))) - so that -Wall
    doesn't emit "null argument" warnings. (Thanks Daniel Kahn Gillmor.)
  - Add t/stringification.t.
  - Fix typos in documentation.
  - Fix bug in new() - it wasn't handling infinity/nan args correctly.

 0.02
  - Replace '_precision' (not exported) with 'ld_get_prec' (exported).
  - Provide 'ld_set_prec'.
  - Remove LONG_DOUBLE_DECIMAL_PRECISION macro.
  - Provide LdtoSTRP.
  - set default precision of stringified values to 18 decimal digits.
