- Server functions can return not_found: true to render the 404 page with status 404. - Page components and window.__PAGE_PROPS__ (and HMR updates) only get props, query, url and error. response_options, redirect, cache settings and res_transform stay on the server, so cookies and private headers no longer end up in the HTML. BunextPageProps is narrowed to match (breaking for code that read server-only fields from component props). - response_options headers go through a Headers object, so repeated headers such as several Set-Cookie survive. - Redirects: status_code wins over permanent; response_options headers and res_transform apply to redirects too. - Gzip for compressible text responses; compress: false to turn it off. - Files the router matches but never bundles (.server.ts, __root, excluded paths and directories) return 404 instead of looping through dev rebuild retries. - Missing public files return 404 rather than 403, so dotted page paths like /users/john.doe fall through to pages again. - importFresh detects rewrites within the filesystem's mtime granularity. - README: self-hosted React (not esm.sh), snake_case option names, static file serving, cache headers, the new options.
