 The `express.urlencoded` method makes the `extended` option `false` by default.
 
+<h3 id="express.static.dotfiles">express.static dotfiles</h3>
+
+In Express 5, the `express.static` middleware's `dotfiles` option now defaults to `"ignore"`. This is a change from Express 4, where dotfiles were served by default. As a result, files inside a directory that starts with a dot (`.`), such as `.well-known`, will no longer be accessible and will return a **404 Not Found** error. This can break functionality that depends on serving dot-directories, such as Android App Links, and Apple Universal Links.
+
+Example of breaking code:
+
+```js
+// v4
+app.use(express.static('public'))
+```
+
+After migrating to Express 5, a request to `/.well-known/assetlinks.json` will result in a **404 Not Found**.
+
+To fix this, serve specific dot-directories explicitly using the `dotfiles: "allow"` option:
+
+```js
+// v5
+app.use('/.well-known', express.static('public/.well-known', { dotfiles: 'allow' }))
+app.use(express.static('public'))
+```
+
+This approach allows you to safely serve only the intended dot-directories while keeping the default secure behavior for other dotfiles, which remain inaccessible.

 In Express 5, the `app.listen` method will invoke the user-provided callback function (if provided) when the server receives an error event. In Express 4, such errors would be thrown. This change shifts error-handling responsibility to the callback function in Express 5. If there is an error, it will be passed to the callback as an argument.
