Release notes

Sourced from astro's releases.

astro@6.4.8

Patch Changes

• #17109 27c80ea Thanks @​ematipico! - Harden the limits on the number of decoding on the URL.

astro@6.4.7

Patch Changes

• #17035 197e50e Thanks @​astrobot-houston! - Fixes getRelativeLocaleUrl, getAbsoluteLocaleUrl, and getAbsoluteLocaleUrlList to strip trailing slashes when trailingSlash: 'never' is configured

• #16967 3719765 Thanks @​astrobot-houston! - Fixes double URL-encoded paths returning 400 Bad Request on on-demand routes

  Previously, any URL containing a double-encoded character (like %255B, which is [ encoded twice) was unconditionally rejected with a 400 Bad Request before middleware or route handlers could run. This broke embedded tools like Sanity Studio whose client-side router legitimately produces double-encoded URLs.

  The fix replaces the rejection approach with iterative decoding — multi-level percent-encoding is now fully resolved to its canonical form before being passed to middleware and route matching. This preserves the security fix for CVE-2025-66202 (middleware authorization bypass via double encoding) because middleware now always sees the fully decoded path, making bypass impossible. For example, /api/%2561dmin is decoded to /api/admin, which middleware can correctly block.

• #17066 2f4d92a Thanks @​matthewp! - Fixes prerendered redirect targets being incorrectly bundled into the SSR function in hybrid mode, causing massive bundle size inflation

• #16882 621beb7 Thanks @​jettwayio! - fix(render): honour compressHTML when joining head elements

• #16892 8d753b0 Thanks @​astrobot-houston! - Fixes custom elements in MDX having their children's slot attribute stripped by the JSX runtime

  When custom elements (tags with hyphens like <my-element>) are used in MDX files, the slot HTML attribute on their children is now correctly preserved. Previously, the shared JSX runtime would treat slot as an Astro slot assignment and remove it from the output, breaking Shadow DOM named slot distribution for web components.

• #16957 544ee76 Thanks @​thelazylamaGit! - Fixes stale inline CSS in server-rendered HTML after CSS file edits during dev

  When editing a CSS file (.css, .scss, etc.) during development, the inline <style> tags in server-rendered HTML would retain old CSS content instead of updating. This caused a brief flash of old CSS (FOUC) on fresh page loads before Vite's client-side HMR corrected the styles.

  The fix ensures that Astro's per-route dev CSS virtual modules are invalidated in both the SSR module graph and the module runner's evaluation cache when a style file changes, so the next page render picks up the fresh CSS.

• #17044 2220d22 Thanks @​astrobot-houston! - Fixes CSS from client:only islands leaking to unrelated pages when Rollup bundles non-CSS-importing modules into the same chunk as CSS-importing modules

• #17040 7c4763d Thanks @​astrobot-houston! - Fixes HMR not triggering for files inside the src/middleware/ directory during dev

• #16672 52fc862 Thanks @​martinheidegger! - Fixes support for numeric IDs in YAML frontmatter when using content collection references

• #16762 9de80ae Thanks @​alexanderdombroski! - Adds a JSON schema to the Wrangler configuration file generated when running astro add cloudflare

• #17046 ef771ec Thanks @​ematipico! - Improves the diagnostics emitted when Astro parses incorrect .astro files.

astro@6.4.6

Patch Changes

• #16765 b10e86e Thanks @​fkatsuhiro! - Fixes an issue where renaming an image file while the dev server is running triggers a build error. Now Astro correctly hot-reloads the image without crashing.

• #17026 add3df1 Thanks @​matthewp! - Hardens addAttribute to drop attribute names containing characters that are invalid per the HTML spec (", ', >, /, =, whitespace)

• #17033 ffda27b Thanks @​matthewp! - Validates the request origin against allowedDomains before fetching prerendered error pages. When allowedDomains is configured and the Host header matches, the original origin is used. Otherwise, the fetch falls back to localhost.

astro@6.4.5

Closing per tracker #115 — astro 5 → 6 in apps/docs is blocked upstream on @astrojs/starlight shipping v6 support (Starlight 0.33.x still peer-deps astro: ^5.1.5). Drive-by bumps will keep failing CI until the Starlight side lands.

Stopping the v6 major here so Dependabot can resume patching within v5.

@dependabot ignore astro major version

Scheduled routine — closing per the plan documented in the Astro 6 upgrade tracker (#115):

the upgrade can't be done as a drive-by — it's a real migration … blocked on @astrojs/starlight shipping v6-compatible release. Recommend closing with ·@·d·ependabot i·gnore t·his major version until #115 is actionable.

Both blocker points (Starlight peer-dep on astro: ^5.1.5 and the @astrojs/tailwind migration path) are unchanged today. Issuing the ignore now.

·@·d·ependabot i·gnore t·his major version

Dependabot can resume bumping within v5 immediately, and within v6 once #115 lands.

Same story as #119 for the astro side — blocked on @astrojs/starlight shipping v6 peer-dep support (^5.1.5 today). Tracked in #115.

·@·d·ependabot i·gnore t·his major version

Closing manually — same story as #119. Prior @dependabot ignore comments (2026-06-25, 2026-07-03, 2026-07-04) didn't take effect, so the drive-by close-via-command loop isn't working from these audit sessions.

Blocker is unchanged: @astrojs/starlight@0.33.x peer-deps astro: ^5.1.5, no v6-supporting Starlight release available yet. Full migration shape lives in #115.

Dependabot may reopen on next scan — that's fine, #115 is the tracking surface.
