 In the following we provide a detailed description of all the breaking changes introduced in v2, which
 should be used as a checklist when converting a piece of code using PyLops from v1 to v2.
 
-- Several operators have deprecated `N` as a keyword. To migrate, pass only `dims` if both `N` and `dims` are currently being passed.
-If only `N` is being passed, ensure it is being passed as a value and not a keyword argument (e.g., change `Flip(N=100)` to `Flip(100)`).
-- `utils.dottest`: The relative tolerance is new set via `rtol` (before `tol`), and absolute tolerance is new supported via the keyword `atol`. When calling it with purely positional arguments, note that after `rtol` comes now first `atol` before `complexflag`. When using `raiseerror=True` it now emits an `AttributeError` instead of a `ValueError`.
