v4.6.4

4.6.4 is a security release. It fixes eight advisories in Nuxt and pulls in nitropack 2.13.6, which fixes three more in Nitro. We recommend upgrading as soon as you can.

⚠️ Behaviour changes

These probably won't affect most apps, but it's worth flagging anyway:

1. Error details in production. When a page fails to render on the server, the error page and the payload now only carry message and data of errors you create with createError. Everything else is stripped.
2. Dev server Host checks. Webpack and rspack dev servers now reject requests with an unexpected Host header, as Vite already does. If you use a custom hostname or tunnel, you'll need to add it to the new devServer.allowedHosts option.
3. workspaceDir detection. When workspaceDir isn't set, Nuxt now only widens it past rootDir to an explicit workspace root or the closest git repository.
4. Nitropack cached routes. cache, swr and isr route rules now only cache GET and HEAD requests, and no longer store responses that set a cookie or send Cache-Control: private or no-store. Wildcard proxy and redirect rules also reject requests whose resolved target would leave the rule's scope.
5. Route rules and encoded slashes. Route rules now match paths that contain encoded slashes, so /api%2Fadmin is covered by a /api/** rule.
