MAINT: All modes in _shared.interpolation.pxd were changed to be consistent with numpy.pad naming conventions. Specifically 'nearest' was changed to 'edge' and 'mirror' was changed to 'reflect'. All functions with a mode argument that rely on these functions had their inputs changed accordingly. For now there is a deprecation warning if the user supplies mode 'nearest'. Mode 'mirror' never appeared in an official release of skimage and so has no corresponding deprecation warning.
