Scikit-image .io.imread changes?

What changes were made after scikit-image 0.14.2 that the newest version fails to read the format while 0.14.2 automatically detects it?

Code example:
image =

Newest version throws ValueError: Could not find a format to read the specified file in single-image mode

I think we moved from matplotlib to imageio. You can verify by doing:, plugin='matplotlib')
