Announcement: scikit-image 0.14.2
=================================

This release handles an incompatibility between scikit-image and NumPy
1.16.0, released on January 13th 2019.

It contains the following changes from 0.14.1:

API changes
-----------
- ``skimage.measure.regionprops`` no longer removes singleton dimensions from

  ``regionprops(label_image)`` calls with
  ``regionprops(np.squeeze(label_image))``

Bug fixes
---------
- Address deprecation of NumPy ``_validate_lengths`` (backport of #3556)
- Correctly handle the maximum number of lines in Hough transforms
  (backport of #3514)
- Correctly implement early stopping criterion for rank kernel noise
  filter (backport of #3503)
- Fix ``skimage.measure.regionprops`` for 1x1 inputs (backport of #3284)

Enhancements
------------
- Rewrite of ``local_maxima`` with flood-fill (backport of #3022, #3447)

Build Process & Testing
-----------------------
- Dedicate a ``--pre`` build in appveyor (backport of #3222)
- Avoid Travis-CI failure regarding ``skimage.lookfor`` (backport of #3477)
- Stop using the ``pytest.fixtures`` decorator (#3558)
- Filter out DeprecationPendingWarning for matrix subclass (#3637)
