[dependabot]

Bumps astro from 6.3.1 to 7.3.5.

Release notes

Sourced from astro's releases.

astro@7.3.5

Patch Changes

• #17736 2b8b2e8 Thanks @​ematipico! - Adds a new container function called renderComponent(), which renders Astro components with inlined styles and scripts.

  Users must import the component with the new ?container query string:

  import { experimental_AstroContainer } from "astro/container";
  import TodoList from "../components/TodoList.astro?container";
  const container = await experimental_AstroContainer.create();
  const _string = container.renderComponent(TodoList);

astro@7.3.4

Patch Changes

• #18063 40896ac Thanks @​adamchal! - Fixes incremental builds repeatedly rendering unchanged pages when modules or compiled CSS reference bundled assets.

• #18053 cf5d72f Thanks @​Princesseuh! - Improves the astro check error shown for TypeScript 7. The command now explains that TypeScript 7 is not currently supported and provides instructions for experimentally type-checking Astro files with TypeScript 7.1 and @astrojs/ts-content-mapper.

• #18086 795a7e4 Thanks @​ump45nose! - Fix double-escaped ampersands in Markdown image alt and title attributes. The __ASTRO_IMAGE_ round-trip now decodes the numeric (&) and named (&) character references the Markdown processors emit, so an & in an alt or title is escaped exactly once in the final HTML instead of twice.

• #18074 0429805 Thanks @​SurefireStudios! - Fix three error names that did not match their documented reference. MissingLocale, MissingIndexForInternationalization and NoManifestAvailable reported names ending in Error in the dev overlay, while their error reference pages are published under the unsuffixed names, so the name shown to users could not be found in the docs.

• #18007 2245837 Thanks @​L4XB! - Fixes the dev server re-evaluating the whole server module graph on every request. The astro:head-metadata plugin invalidated its component metadata virtual module from its own transform hook, so each evaluation of that module scheduled the next one. Adapters that run requests outside Vite's module runner, such as @astrojs/cloudflare, paid for a full re-evaluation of the server graph on every request for the lifetime of the process.

• #18096 43657c4 Thanks @​matthewp! - Fixes domain-based i18n routing to respect security.allowedDomains when selecting a locale from request host headers

• #18043 8a53a8b Thanks @​astro-factory! - Fixes image.responsiveStyles emitting invalid object-position CSS values for same-axis keyword pairs (top bottom, left right, etc.)

• #18029 c08252d Thanks @​matthewp! - Runs astro dev and astro preview in the foreground when an AI agent is detected on Windows, allowing the agent to manage the process lifetime. Pass --background explicitly to request an Astro-managed background process. Agent-inferred backgrounding remains enabled on other platforms.

  • @​astrojs/markdown-satteri@​0.4.2

astro@7.3.3

Patch Changes

• #17651 504333c Thanks @​sxzz! - Refactors internal version handling to use a smaller, ESM-native dependency

• #17942 0bc5715 Thanks @​matthewp! - Returns appropriate 400 and 404 responses from the image endpoint for invalid and missing local image paths

• #17700 b2222fc Thanks @​winklemad! - Fixes Astro.preferredLocaleList returning an empty list when a locale is configured with the object form ({ path, codes }) and the browser sends the code with different casing or an underscore, such as en-US matching a configured en-us

• #17941 394ff79 Thanks @​matthewp! - Fixes astro preview --ignore-lock (and astro dev --ignore-lock) being refused when run from an AI agent environment. The flag now starts the server in the foreground instead of erroring, since agent detection only inferred background mode and was never explicitly requested. An explicit --background combined with --ignore-lock still errors.

• #17928 3277927 Thanks @​ArmandPhilippot! - Fixes TypeScript autocompletion for getImage() to suggest all available predefined options.

Changelog

Sourced from astro's changelog.

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.

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.

6.4.5

Reviewed the Astro 7 migration against its official upgrade guide: https://docs.astro.build/en/guides/upgrade-to/v7/. This site is static, has no adapter, custom Vite/Markdown plugins, reserved fetch entrypoint, removed database integration, or transition internals to migrate.

Updated the branch with current main and added an explicit Node >=22.19 engine so local builds advertise the same supported runtime as CI and the repository. npm ci --prefix website and the complete production build pass: 14 pages, including both languages and privacy/support pages. No Astro compiler errors. Fresh CI will gate merge.

Final verification: all applicable CI checks are green on 0943f250b741269adedfc73fdb33c9a5416b80b0 (Node 22/24, coverage, production audit, browser E2E, and path-selected native/website checks). Merging the reviewed and corrected branch.
