Astro 7.1.2

Patch Release Highlights

Astro 7.1.2 is a patch release that addresses several important bugs and updates a core dependency. This release focuses on improving reliability across the framework's request handling and prefetching mechanisms.

Cookie Dependency Updated to v2

A key change in Astro 7.1.2 is the update of the cookie dependency to version 2. Cookie values that consist entirely of URL-safe characters are no longer percent-encoded in Set-Cookie headers. Additionally, encoded values now round-trip exactly as before, making cookie handling more predictable and standards-compliant.

Critical Bug Fixes

• Astro.locals persistence — A bug where mutated Astro.locals values during the request lifecycle were lost and not passed through to custom error pages (404.astro and 500.astro) has been fixed. This ensures that request-scoped data set via middleware or other lifecycle hooks is available when error pages need it.
• Prefetch fetch fallback — In WebKit-based browsers (Safari), the <link rel="prefetch"> tag is not supported, so Astro falls back to the fetch() API for prefetch hints. On flaky connections, this fallback could throw an unhandled TypeError: Load failed rejection that surfaced to the page's global error handlers. Astro 7.1.2 now swallows this failure with a proper .catch() handler, preventing unhandled promise rejections.
