v18.0.0	Passing an invalid callback to the `callback` argument now throws `ERR_INVALID_ARG_TYPE` instead of `ERR_INVALID_CALLBACK`.
v10.0.0	The `callback` parameter is no longer optional. Not passing it will throw a `TypeError` at runtime.
v7.6.0	The `existingPath` and `newPath` parameters can be WHATWG `URL` objects using `file:` protocol. Support is currently still experimental.
v7.0.0	The `callback` parameter is no longer optional. Not passing it will emit a deprecation warning with id DEP0013.
