<h4 id="router.param">router.param(fn)</h4>
The `router.param(fn)` signature was used for modifying the behavior of the `router.param(name, fn)` function. It has been deprecated since v4.11.0, and Express 5 no longer supports it at all.
<h4 id="express.static.mime">express.static.mime</h4>
In Express 5, `mime` is no longer an exported property of the `static` field.
