 These combine the browser's `Accept-Langauge` header, and your `locales` to automatically respect your visitor's preferred languages.
 
 - `Astro.preferredLocale`:  Astro can compute a **preferred locale** for your visitor if their browser's preferred locale is included in your `locales` array. This value is undefined if no such match exists.
-
-
 - `Astro.preferredLocaleList`: An array of all locales that are both requested by the browser and supported by your website. This produces a list of all compatible languages between your site and your visitor. The value is `[]` if none of the browser's requested languages are found in your `locales` array. If the browser does not specify any preferred languages, then this value will be [`i18n.locales`].
+- `Astro.currentLocale`: The locale computed from the current URL, that matches what's configured in [`i18n.locales`]. When the `routingStrategy` is set to `"prefix-other-locales"`, the value will be `i18n.defaultLocale` for any URL that doesn't contain any locale.
