Extracting Adapted Mesh in FEniCS

Errors
1

To extract the adapted mesh the code used was:

mesh0 = mesh.root_node()
mesh1 = mesh.leaf_node()
plot(mesh0, title="Initial mesh")
plot(mesh1, title="Final mesh")

This no longer seems to work and throws an error:

AttributeError: 'dolfin.cpp.mesh.Mesh' object has no attribute 'root_node'

I would like to know how to do this on the newer version. Any suggestion would be very helpful.
Thank You.
