- Update to 0.23.2
## Bug Fixes
* Make sure skimage.util.img_as_ubyte supports the edge case
where dtype('uint64').type of the provided image is
np.ulonglong instead of np.uint64 (#7392).
## Documentation
* Add date to 0.23.1 release notes (#7384).
* Fix docstring of connectivity parameter in
skimage.segmentation.watershed (#7360).
## Infrastructure
* Ignore Sphinx warning about unpickable cache (#7400).
* Simplify instructions on changelist in PR template (#7401).
## Maintenance
* Use numpy.inf instead of deprecated numpy.infty (#7386).
* Update Ruff config (#7387).
* Update matrix and names of Azure pipelines configuration
(#7390).
* Use upload- and download-artifact v4 (#7389).
* Ignore arch specific cast warnings originating from astype in
tests (#7393).
* Update link to numpydoc example.py (#7395).
- Release 0.23.1/0.23.0
## Highlights
* Ensure skimage.morphology.closing and
skimage.morphology.opening are extensive and anti-extensive,
respectively, if the footprint is not mirror symmetric (#6695).
* Add parameter mode to binary_erosion, binary_dilation,
binary_opening and binary_closing in skimage.morphology. These
new parameters determine how array borders are handled (#6695).
* Add parameters mode and cval to erosion, dilation, opening,
closing, white_tophat, and black_tophat in skimage.morphology.
These new parameters determine how array borders are handled
(#6695).
* Speedup skimage.util.map_array by parallelization with Cython's
prange (#7266).
## New Features
* Add new intensity_std property to skimage.measure.regionprops
which computes the standard deviation of the intensity in a
region (#6712).
* Add parameter mode to binary_erosion, binary_dilation,
binary_opening and binary_closing in skimage.morphology. These
new parameters determine how array borders are handled (#6695).
* Add functions mirror_footprint and pad_footprint to
skimage.morphology (#6695).
* Add parameters mode and cval to erosion, dilation, opening,
closing, white_tophat, and black_tophat in skimage.morphology.
These new parameters determine how array borders are handled
(#6695).
* Add new parameter spacing to segmentation.expand_labels to
support anisotropic images (#7080).
## API Changes
* Drop support for Python 3.9 (#7217).
* Parameters shift_x and shift_y in skimage.morphology.erosion
and skimage.morphology.dilation are deprecated. Use
pad_footprint or modify the footprint manually instead (#6695).
* Remove unexpected value scaling in
skimage.morphology.skeletonize_3d for non-binary input images.
skeletonize_3d now always returns a binary array like similar
functions (#7095).
* Deprecate function skimage.feature.plot_matches in favor of
skimage.feature.plot_matched_features (#7255).
* Deprecate skimage.morphology.skeletonize_3d in favor of just
skimage.morphology.skeletonize (#7094).
* Deprecate parameter output in skimage.filters.gaussian; use out
instead (#7225).
* Change the default value of the parameters shift_x, shift_y and
shift_z from False to 0 in the skimage.filters.rank functions.
This has not impact on the results. Warn in case boolean shifts
are provided from now on (#7320).
* Performance
* Add lazy loading to skimage.metrics module (#7211).
* Speedup skimage.util.map_array by parallelization with Cython's
prange (#7266).
## Bug Fixes
* Add exception to avoid surprising result when image is too
small for the given parameters in skimage.feature.hog (#7153).
* Ensure skimage.morphology.closing and
skimage.morphology.opening are extensive and anti-extensive,
respectively, if the footprint is not mirror symmetric (#6695).
* Avoid a TypeError in
skimage.registration.phase_cross_correlation when the real-time
shift cannot be determined (disambiguate=True). Display a
warning instead (#7259).
* Fix logic in skimage.graph.pixel_graph which raised a TypeError
when the parameter edge_function was provided without a mask
(#7310).
* Ensure cache stays empty when cache=False is passed to
skimage.measure.regionprops (#7333).
