Performance Optimizations
-------------------------

-  Change ``wiggle_interval`` to return ``success`` bool instead of
   raising an exception. This allows the implicitization approach to use
   it without having to use exceptions for flow-control. (Fixes
   `#22 <https://github.com/dhermes/bezier/issues/22>`__.)
-  Switching Fortran speedups from ``f2py`` to Cython (this is because
   ``f2py`` artificially limits the feature set of Fortran, i.e. user
   defined types)
-  Moving some more code to Fortran (e.g. ``bbox_line_intersect()``
   `3dcf640 <https://github.com/dhermes/bezier/commit/3dcf64090bb5874320dcde86eaf449e94278dd08>`__)

New Features
------------

-  Making Fortran features available outside of Python (see `Native
   Libraries <https://bezier.readthedocs.io/en/0.5.0/native-libraries.html>`__)
-  C headers for each Fortran module (via the ``bezier.get_include()``
   `function <https://bezier.readthedocs.io/en/0.5.0/reference/bezier.html#bezier.get_include>`__)

   -  Cython ``.pxd`` declarations for all Fortran modules
   -  ``libbezier`` static library (via the ``bezier.get_lib()``
      `function <https://bezier.readthedocs.io/en/0.5.0/reference/bezier.html#bezier.get_lib>`__)

-  Implementing ``bezier_roots()`` polynomial root
   `solver <https://bezier.readthedocs.io/en/0.5.0/algorithm-helpers.html#bezier._implicitization.bezier_roots>`__
   for polynomials written in Bernstein basis.
   (`0dd6369 <https://github.com/dhermes/bezier/commit/0dd6369b0f77e4c0cf8113f2d25812addc90482a>`__)

Miscellany
----------

-  Getting ``bezier``
   `published <http://joss.theoj.org/papers/10.21105/joss.00267>`__ in
   the Journal of Open Source Science (JOSS). See
   `review <https://github.com/openjournals/joss-reviews/issues/267>`__.
   (`e6c4536 <https://github.com/dhermes/bezier/commit/e6c45360f0c8412ae90d967463a14c49490d70ee>`__
   and
   `975ac6b <https://github.com/dhermes/bezier/commit/975ac6b1a4313db4dcdc17396d6d34561005939e>`__)
-  Updating error message for ``locate()`` methods and adding a note
   that ``locate()`` / ``evaluate*()`` are (essentially) inverses. H/T
   to `@pdknsk <https://github.com/pdknsk>`__
   `#36 <https://github.com/dhermes/bezier/pull/36>`__
-  Using Fortran-contiguous arrays in ``_check_non_simple()``.
   (`b06c78e <https://github.com/dhermes/bezier/commit/b06c78e50d53bf673bcf0b71fa84b36c8df564d8>`__)
-  Moving most of ``Curve.subdivide()`` and ``Surface.subdivide()``
   logic into helpers. This is part of an effort to make all helpers
   take low-level data types rather than ``Curve``\ s, ``Surface``\ s,
   etc.
   (`34515bd <https://github.com/dhermes/bezier/commit/34515bd6246f57fbb311b4089520a24e8237294a>`__
   and
   `1fc80e5 <https://github.com/dhermes/bezier/commit/1fc80e54ad1b45cb628af06e5a2100eeb9282865>`__)
-  Split ``speedup.f90`` into submodules ``curve.f90``, ``surface.f90``,
   etc.
   (`75349b7 <https://github.com/dhermes/bezier/commit/75349b745063a9bbc623808b3f7bbf6b7641c008>`__,
   `dfd6bba <https://github.com/dhermes/bezier/commit/dfd6bba303ac0a8492fac1f309086b685e52ab59>`__,
   `7096a9d <https://github.com/dhermes/bezier/commit/7096a9d646930378476e650c77d0652a48bf148a>`__,
   `c326c00 <https://github.com/dhermes/bezier/commit/c326c00a5c0ee74f9aa53c2b104ac6d4eb5c6794>`__)
-  Adding ``BEZIER_JOURNAL`` option to ``setup.py``. This stores a
   record of compiler commands invoked during installation. See `Native
   Libraries <https://bezier.readthedocs.io/en/0.5.0/native-libraries.html>`__
   for more details.
