<h3 id="res.sendFile.options">res.sendFile() and express.static() options</h3>

The following options to the `res.sendFile()` and `express.static()` functions are no longer supported:

* `hidden`: Use the `dotfiles` option instead. Note that the default value of `dotfiles` is now `"ignore"`.
* `from`: Use the `root` option instead.

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.
