Release notes

Sourced from astro's releases.

astro@6.3.8

Patch Changes

• #16830 f2bf3cb Thanks @​matthewp! - Fixes 404s for dynamically imported JS chunks when using an adapter with assetQueryParams (e.g. Vercel skew protection)

• #16831 ace96ba Thanks @​astrobot-houston! - Fixes a misleading GetStaticPathsRequired error when a redirect is configured from a dynamic route to a static (or less-dynamic) destination. For example, '/project/[slug]': '/' previously produced a confusing error pointing at index.astro. Astro now detects the parameter mismatch at config validation time and throws a clear InvalidRedirectDestination error naming the missing parameters.

• #16702 b7d1758 Thanks @​matthewp! - Fixes scoped styles from .astro components being dropped when rendered inside MDX content (<Content /> from render(entry)) passed through a named slot using <Fragment slot="X">. The Fragment component now eagerly evaluates its slot contents to ensure propagating components register their styles before head content is flushed.

• #16823 3df6a45 Thanks @​astrobot-houston! - Fixes missing CSS for conditionally rendered Svelte components in production builds

• #16836 3d7adfa Thanks @​LongYC! - Document compressHTML: "jsx" config is only available since Astro v6.2.0

• #16864 334ce13 Thanks @​cheets! - Fixes a false-positive Internal Warning: route cache overwritten logged on every SSR request for dynamic routes

astro@6.3.7

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.

Greptile Summary

Routine automated dependency bump of astro from 6.3.6 to 6.3.8 across two patch releases. Both packages/web/package.json and package-lock.json are updated consistently.

• 6.3.7: Fixes request body handling in the Node adapter (Buffer/Uint8Array/ArrayBuffer), corrects vite.build options being ignored for client builds, fixes custom elements in MDX bypassing the renderer pipeline, fixes dynamic routes returning 400 on URLs with literal %, and restores astro:i18n importability from client <script> blocks.
• 6.3.8: Fixes 404s for dynamically-imported JS chunks with assetQueryParams (e.g. Vercel skew protection), fixes a misleading GetStaticPathsRequired error for dynamic-to-static redirects, fixes scoped styles being dropped when .astro components are rendered inside MDX named slots, fixes missing CSS for conditionally-rendered Svelte components in production builds, and silences a false-positive SSR route-cache warning.

Confidence Score: 5/5

Safe to merge — this is a patch-only bump with no breaking changes, only bug fixes.

Both changed files are consistent with each other: package.json updates the version constraint and package-lock.json resolves it to the matching tarball with a valid integrity hash. The two patch releases contain only bug fixes (no API changes), and the lockfile shows no other dependency was touched.

No files require special attention.
