Astro

Recently shipped a build timings flag, faster content sync for large collections, and React island link fixes.

Builds can now show where time goes. astro build --timings prints a per-phase summary when the build finishes, covering integrations, Markdown processing, syntax highlighting, and image processing, so you can see what to optimize first.

Content sync got much faster for large collections. With experimental.collectionStorage: "chunked", the chunking step on a store of roughly 44k entries dropped from about 60 seconds to under a second, with byte-identical output.

React islands keep the links their components render. Component-rendered stylesheets, preloads, and modulepreloads now survive server rendering, along with React's automatic resource hints. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#@astrojs/react@7-1-3]

Several adapter fixes landed for common breakage:

• Astro on Cloudflare no longer returns a 404 when a browser revalidates a cached local image with If-None-Match; it now answers 304 Not Modified. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#@astrojs/cloudflare@14-4-5]
• On Node.js 26, on-demand routes keep their request body when staticHeaders is enabled. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#@astrojs/node@11-1-10]
• Vercel builds no longer crash on unrecognized dependency-resolution warnings. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#@astrojs/vercel@11-0-19]
• astro dev with the Cloudflare adapter no longer fails when a server dependency requires node-fetch. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#astro@7-4-2]

The image endpoint now handles directories whose names differ only by letter case correctly on case-sensitive filesystems. Most other integrations on the 2026-11-05 release train shipped only the shared dependency bump. [source: https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#astro@7-4-7]
