- 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).
