 You may be wondering why sharing is a separate typestate here; shouldn't that just be read-only access to a `T` that someone else owns?
 However, that clearly doesn't work for `&Cell`; to explain types with interior mutability we *need* sharing as a separate state.
 I explained this in more detail in the previous post, but as a quick example consider that, if you fully own a `RefCell`, the first field (storing the current count of readers/writers) has no special meaning whatsoever.
-This is witnessed by [`RefCell::get_mut`](https://doc.rust-lang.org/beta/std/cell/struct.RefCell.html#method.get_mut) ignoring that field.
+This is witnessed by [`RefCell::get_mut`](https://doc.rust-lang.org/stable/std/cell/struct.RefCell.html#method.get_mut) ignoring that field.
 In fact, it would be sound to add a `RefCell::reset(&mut self)` that just resets this field to `0`.
