## Justification for blocked versions
* Cython 0.28.2 was empircally found to fail tests while other patch-releases 0.28.x do not
* Cython 0.29.0 erroneously sets the `__path__` to `None`. See https://github.com/cython/cython/issues/2662
* Cython 0.29.18 fails due to a bad definition of M_PI. See https://github.com/cython/cython/issues/3622
* matplotlib 3.0.0 is not used because of a bug that collapses 3D axes (see https://github.com/scikit-image/scikit-image/pull/3474 and https://github.com/matplotlib/matplotlib/issues/12239).
* pillow 7.1.0 fails on png files, See https://github.com/scikit-image/scikit-image/issues/4548
* pillow 7.1.1 fails due to https://github.com/python-pillow/Pillow/issues/4518
* imread 0.7.2 fails due to build failure https://github.com/luispedro/imread/issues/36
* sphinx-gallery 0.8.0 is banned due to bug introduced on binder: https://github.com/scikit-image/scikit-image/pull/4959#issuecomment-687653537
