Astro 7.2.3

Astro 7.2.3 was released on August 18, 2026 as a patch release focused on stability fixes for content collections, the dev server, and server-side request handling.

Fixes

• Memory usage with chunked collection storage — Astro could run out of memory when experimental.collectionStorage is set to chunked and multiple concurrent updates hit the same collection. This has been resolved.
• Stale dev-server routes — the dev server could match stale routes after pages were added, removed, or renamed, forcing a restart. Fixed.
• Composable request helpers — astro/fetch helpers no longer throw when used on requests rewritten via Astro.rewrite() or next().
• Malformed Host header crash — fixed a crash on requests with invalid ports (e.g. example.com:65536), which invalidated the constructed request URL and broke the recovery fallback.

Internal Refactor

Astro refactored its internal server-side request handling. All documented public APIs, including App and NodeApp, keep their signatures. However, the undocumented app.pipeline property and the AppPipeline export from astro/app have been removed — adapters should use the new app.getLogger() instead. The refactor also means new FetchState(request) now works anywhere inside a built Astro server, including custom src/fetch.ts entrypoints.

Documentation and JSDoc

Several JSDoc issues were corrected for the server and fonts config options, i18n examples, and code-block indentation, plus a broken font-providers link.
