Patch Changes

• #​16821 9c76b12 Thanks @​astrobot-houston! - Fixes request body handling in the Node adapter when req.body is a Buffer, Uint8Array, or ArrayBuffer. Previously, binary body data was incorrectly JSON-stringified (producing {"type":"Buffer","data":[...]}) instead of being passed through directly. This affected libraries like serverless-http that set req.body to a Buffer.

• #​16785 de96360 Thanks @​astrobot-houston! - Fixes vite.build.minify, vite.build.sourcemap, and vite.build.rollupOptions.output (e.g. compact) being ignored for client-side builds. These top-level Vite build options are now properly forwarded to the client environment, with environment-specific overrides (vite.environments.client.build.*) taking priority when set.

• #​16819 b5dd8f1 Thanks @​astrobot-houston! - Fixes custom elements in MDX files bypassing the renderer pipeline. Custom elements (tags containing hyphens like <my-element>) in .mdx files are now routed through registered renderers for SSR, matching the behavior of .astro files. If no renderer claims the element, it falls back to rendering as raw HTML.

• #​16808 765896c Thanks @​ematipico! - Fixes dynamic routes returning 400 Bad Request when the URL contains a literal % character, such as paths built with encodeURIComponent('%?.pdf')

• #​16804 90d2aca Thanks @​jp-knj! - Fixes a v6 regression where astro:i18n could not be imported from client <script> blocks.

v6.3.6

Patch Changes

• #​16774 8f77583 Thanks @​astrobot-houston! - Fixes markdown images with empty alt text (![](image.jpg)) in content collections dropping the alt attribute entirely. The alt="" attribute is now correctly preserved in the rendered HTML output, which is important for accessibility (indicating decorative images).

• #​16776 3d10b5e Thanks @​matthewp! - Fixes HMR serving stale content when components are passed as props via getStaticPaths()

• #​16784 7453860 Thanks @​ematipico! - Improved the printing of the build time if it goes over the 60 seconds.

• #​16665 3dbbcee Thanks @​Princesseuh! - Fixes remote SVG sources erroring with dangerouslyProcessSVG after the v6.3 SVG-processing gate. The default Sharp service now resolves the output format from the source up-front when it can (URL extension, data: MIME, ESM metadata), and from the actual buffer at request time when it can't, so SVG sources pass through untouched without needing to set image.dangerouslyProcessSVG: true or an explicit format="svg".

  The error message has also been updated to point at format="svg" as the simpler workaround when an SVG source is encountered without dangerouslyProcessSVG enabled.

• #​16777 1754b91 Thanks @​matthewp! - Fixes HMR serving stale content for dynamically imported components through barrel files

• #​16730 068d924 Thanks @​harshagarwalnyu! - Fixes an issue where the file() content loader did not generate a valid JSON Schema for collections whose JSON or YAML data is a top-level array instead of an object.
