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



Version 0.14
------------
* Remove deprecated ``ntiles_*` kwargs in ``equalize_adapthist``.
* Remove deprecated ``skimage.restoration.nl_means_denoising``.


Version 0.13
------------
* Remove deprecated `None` defaults for `skimage.exposure.rescale_intensity`
* Remove deprecated `skimage.filters.canny` import in `filters/__init__.py`
  file (canny is now in `skimage.feature.canny`).
    * Don't forget to complete api_changes.txt.
     (`GitHub discuss <https://github.com/scikit-image/scikit-image/pull/1113>`__ )
* Remove deprecated ``skimage.filter`` module.
* Remove deprecated edge filters `hsobel`, `vsobel`, `hscharr`, `vscharr`,
  `hprewitt`, `vprewitt`, `roberts_positive_diagonal`,
  `roberts_negative_diagonal` in `skimage/filters/edges.py`
* Remove supported for renamed edge mode, 'nearest' (it is now 'edge').  This
  involves removing the function _mode_deprecations from skimage._shared.utils
  as well as any uses of _mode_deprecations from restoration/_denoise.py,
  _shared/interpolation.pyx, transform/_geometric.py, and transform/_warps.py



Version 0.12
------------
* Change `label` to mark background as 0, not -1, which is consistent with
  SciPy's labelling.
* Remove `skimage.morphology.label` from `skimage.morphology.__init__`--it now
  lives in `skimage.measure.label`.
* Remove deprecated `reverse_map` parameter of `skimage.transform.warp`
* Change deprecated `enforce_connectivity=False` on skimage.segmentation.slic
  and set it to True as default
* Remove deprecated `skimage.measure.fit.BaseModel._params` attribute
* Remove deprecated `skimage.measure.fit.BaseModel._params`,
  `skimage.transform.ProjectiveTransform._matrix`,
  `skimage.transform.PolynomialTransform._params`,
  `skimage.transform.PiecewiseAffineTransform.affines_*` attributes
* Remove deprecated functions `skimage.filters.denoise_*`
* Add 3D phantom in `skimage.data`
* Add 3D test case of `skimage.feature.phase_correlate`
