TODO.txt

Remember to list any API changes below in `doc/source/api_changes.txt`.


Version 0.15
------------
* Finalize ``skimage.future.graph`` API.
* Finalize ``skimage.future.manual_segmentation`` API.
* Change the default value of `block_norm` in ``skimage.feature.hog` to L2-Hys,
  update the reference .npy in ``skimage.data`` and `skimage/feature/tests/test_hog.py`.

Version 0.16
------------
* In ``skimage.transform.resize``, ``skimage.transform.pyramid_reduce``,
  ``skimage.transform.pyramid_laplacian``,
  ``skimage.transform.pyramid_gaussian``,
  ``skimage.transform.pyramid_expandset``, set default value of
  ``multichannel`` to False
* Remove ``_multichannel_default`` from ``skimage.transform._warps.py``, and no
  longer call it from within the ``resize`` or ``pyramid_*`` transforms.
* Remove checks for the ``multichannel`` deprecation warnings in several tests
  in ``skimage.transform.tests.test_pyramids.py`` and
  ``skimage.transform.tests.test_warps.py``.
* Remove `flatten` for `imread` in ``skimage.io._io.py``.
* Remove `as_grey` for `load` in ``skimage.data.__init__.py``.
* Remove deprecated argument ``visualise`` from function skimage.feature.hog
* Remove deprecated module ``skimage.novice``
  * Remove the ``save-demo.jpg`` line from ``.gitignore``
  * Remove the warning filter from ``conftest.py``
* In ``skimage.measure._regionprops``, remove all references to
  ``coordinates=``, ``_xycoordinates``, and ``_use_xy_warning``.
* In ``skimage.measure.moments_central``, remove ``cc`` and ``**kwargs``
  arguments.
* In ``skimage.morphology.remove_small_holes``, remove ``min_size`` argument.
* In ``skimage.filters.median``, change default from ``behavior='rank'`` to
  ``behavior='ndimage'``.

Version 0.17
------------

* In ``skimage.filters.median``, remove the parameters ``mask``, ``shift_x``,
  and ``shift_y``.

Other
-----
* Remove legacy pretty printing workaround for ``pytest`` in ``conftest.py``
  once minimal required ``numpy`` is set to >= 1.14.0.
* Remove deprecated ``Hxx, Hxy, Hyy`` API of ``hessian_matrix_eigvals`` in
  ``skimage.feature.corner``.
* Remove the conditional warning logic when ``numpy`` is set to >= 1.15.0
  for ``scipy`` and ``pywl`` (``pywavelet``) in ``test_lpi_filter.py`` and
  ``test_denoise.py`` regarding multidimensional indexing.
* Remove the conditional warning logic when ``numpy`` is set to >= 1.15.0
  for sparse matricies (``np.matrix``) used by scipy.sparse in
  ``test_random_walker.py``. Note that there is also a chance ``scipy.sparse``
  moves away from using ``np.matrix`` in a future version too.
* Remove the conditional import and function call when ``numpy`` is set
  to > 1.15.x in ``skimage/util/arraycrop.py``.
* When minimum supported version of ``scipy`` reaches 0.18, use 
  ``scipy.fftpack.next_fast_len`` directly in 
  ``skimage.feature.masked_register_translation``.
* Monitor SciPy for a new release that passes PYTHONOPTIMIZE builds
  `https://github.com/scipy/scipy/pull/9373`. This was identified as an issue
  in SciPy 1.1.0. When SciPy becomes compatible with PYTHONOPTIMIZE, add an
  environment variable ``PYTHONOPTIMIZE=2`` to one of the builds.
