mesh.cells used to be a dictionary of the form
mesh.cells used to be a dictionary of the form

{ "triangle": [[0, 1, 2], [0, 2, 3]], "quad": [[0, 7, 1, 10], ...] }

From 4.0.0 on, mesh.cells is a list of tuples,

[ ("triangle", [[0, 1, 2], [0, 2, 3]]), ("quad", [[0, 7, 1, 10], ...]) ]

This has the advantage that multiple blocks of the same cell type can be accounted for. Also, cell ordering can be preserved.

You can now use the method mesh.get_cells_type("triangle") to get all cells of "triangle" type, or use mesh.cells_dict to build the old dictionary structure.

mesh.cell_data used to be a dictionary of the form

{ "triangle": {"a": [0.5, 1.3], "b": [2.17, 41.3]}, "quad": {"a": [1.1, -0.3, ...], "b": [3.14, 1.61, ...]}, }

From 4.0.0 on, mesh.cell_data is a dictionary of lists,

{ "a": [[0.5, 1.3], [1.1, -0.3, ...]], "b": [[2.17, 41.3], [3.14, 1.61, ...]], }

Each data list, e.g., mesh.cell_data["a"], can be zipped with mesh.cells.

An old-style cell_data dictionary can be retrieved via mesh.cell_data_dict.
