Version 0.25
------------

Other
-----
* Remove warningsfilter for imageio and Pillow once
  https://github.com/python-pillow/Pillow/pull/7125 is shipped in the minimal required
  version of pillow (probably the release after Pillow 9.5.0).
* Once NumPy 1.25.0 is minimal required version:
    * Remove optional test for a NaN-related deprecation warning from numpy.clip in
      skimage/exposure/tests/test_exposure.py::test_rescale_nan_warning
* Delete FREE_THREADED_BUILD block in `.github/scripts/setup-*-env.sh` once free-threaded
  wheels of Cython are available on PyPi.
* Update `central_pixel` once `sp.sparse.csgraph` supports the array interface (scipy >= 1.15)
* Finalize ``skimage.future.manual_segmentation`` API,
  see https://github.com/scikit-image/scikit-image/issues/2624

Post numpy 2
------------
- Remove try except blocks following comment starting
  `# TODO: when minimum numpy`
  in `skimage/color/colorconv.py`, `skimage/color/tests/test_colorconv.py`,
  `skimage/measure/_blur_effect.py`, and `skimage/util/tests/test_montage.py`
- Remove `handle_np2` from `skimage/conftest.py`
- Once matplotlib doesn't constrain to numpy<2.0 via contourpy (or 2.0 is
  minimal required version): consider re-adding matplotlib to the test
  dependencies. Also remove temporary assert for NumPy 2.0 in
  `nightly_wheel_build.yml`.
- Remove references to `numpy.bool8` once NumPy 2.0 is minimal required version.
- scipy>=1.12: remove SCIPY_CG_TOL_PARAM_NAME in `_shared.compat.py`.
- Remove `np2` check in `skimage/feature/brief.py`.
