Version 1.1.7 (2018-07-11)
==========================

* Update MPFR 4.0.1-p6 -> 4.0.1-p9.

Version 1.1.6 (2018-05-29)
==========================

* Automatically work around Rust issue #47048.

Version 1.1.5 (2018-05-02)
==========================

* Update MPFR 4.0.1 -> 4.0.1-p6.

Version 1.1.4 (2018-04-23)
==========================

* Add missing GMP, MPFR and MPC functions that take a `*mut FILE`
  argument.

Version 1.1.3 (2018-04-05)
==========================

* Fix linkage of MPFR `uj` and `sj` functions.

Version 1.1.2 (2018-04-05)
==========================

* Add missing MPFR and MPC functions with `uj` and `sj`, using
  `c_ulonglong` and `c_longlong` respectively.
* Add missing MPFR `dump` function.

Version 1.1.1 (2018-02-09)
==========================

* Update MPFR 4.0.0 -> 4.0.1.
* Fix the type of the `tab` parameter of `mpfr::sum` to
  `*const *mut mpfr_t` instead of `*mut *mut mpfr_t`.
* Document the `DEP_GMP_LIMB_BITS` build script metadata.
* Add `DEP_GMP_OUT_DIR`, `DEP_GMP_LIB_DIR`, and `DEP_GMP_INCLUDE_DIR`
  build script metadata.

Version 1.1.0 (2018-01-12)
==========================

* Update MPFR 3.1.6-p1 -> 4.0.0.
* Update MPC 1.0.3 -> 1.1.0.
* Deprecate and hide documentation for `mpfr::rnd_t::RNDNA`;
  `MPFR_RNDNA` is not documented by MPFR, and mpfr.h says it should
  not be used.
* Use `c_int` instead of `#[repr(C)] enum` for the private enumerated
  type inside `#[repr(C)] struct randstate_t`.

  `mpc::realref_const()` and `mpc::imagref_const()`.
* Add inline version of functions which are inline in gmp.h, mpfr.h.
* Bug fix: `gmp::mpz_even_p()`.

Version 1.0.2 (2017-05-20)
==========================
