AstroEco is Releasing…

Patch Changes

• #16161 b51f297 Thanks @matthewp! - Fixes a dev rendering issue with the Cloudflare adapter where head metadata could be missing and dev CSS/scripts could be injected in the wrong place

• #16110 de669f0 Thanks @tmimmanuel! - Fixes skew protection query parameters not being appended to inter-chunk JavaScript imports in client bundles, which could cause version mismatches during rolling deployments on Vercel

• #16162 a0a49e9 Thanks @rururux! - Fixes an issue where HMR would not trigger when modifying files while using @astrojs/cloudflare with prerenderEnvironment: 'node' enabled.

• #16142 7454854 Thanks @rururux! - Fixes HTML content being incorrectly escaped as plain text when rendering a MDX component using the AstroContainer APIs.

• #16116 12602a9 Thanks @riderx! - Fixes a bug where page-level CSS could leak between unrelated pages when traversing style parents across top-level route boundaries

• #16178 a7e7567 Thanks @matthewp! - Fixes SSR builds failing with "No matching renderer found" when a project only has injected routes and no src/pages/ directory

Patch Changes

• #16180 1d1448c Thanks @matthewp! - Pre-optimizes @preact/signals and preact/hooks in the Vite dep optimizer to prevent late discovery triggering full page reloads during dev

Patch Changes

• #16034 814406d Thanks @alexanderniebuhr! - Fixes generated redirect files to respect Astro’s trailingSlash configuration, so redirect routes work with the expected URL format in built output instead of returning a 404 when accessed with a trailing slash.

Patch Changes

• Updated dependencies [814406d]:
  • @astrojs/underscore-redirects@1.0.3

Patch Changes

• #16170 d0fe1ec Thanks @bittoby! - Fixes edge middleware next() dropping the HTTP method and body when forwarding requests to the serverless function, which caused non-GET API routes (POST, PUT, PATCH, DELETE) to return 404

Patch Changes

• Updated dependencies [814406d]:
  • @astrojs/underscore-redirects@1.0.3

Patch Changes

• #16122 9a2113b Thanks @matthewp! - Fixes dependency installation failing on Windows when using Bun as the package manager

Patch Changes

• #16109 c887b4a Thanks @matthewp! - Fix HMR crash when editing content collection files caused by Vite's SSR transform colliding with zod v4's meta export

• Updated dependencies []:

  • @astrojs/underscore-redirects@1.0.2

Patch Changes

• #16104 47a394d Thanks @matthewp! - Fixes astro preview ignoring vite.preview.allowedHosts set in astro.config.mjs

• #16047 711f837 Thanks @matthewp! - Fixes catch-all routes incorrectly intercepting requests for static assets when using the @astrojs/node adapter in middleware mode.

• #15981 a60cbb6 Thanks @moktamd! - Fix Zod v4 validation error formatting to show human-readable messages instead of raw JSON

Patch Changes

• #16106 d241012 Thanks @matthewp! - Fixes dependency installation failing on Windows when running npm create astro@latest. The previous fix for DEP0190 warnings incorrectly assumed .cmd shims could be spawned directly without a shell — on Windows, .cmd files require cmd.exe to execute. Package manager commands are now invoked via cmd.exe /d /s /c on Windows. Also fixes the [object Object] error message that appeared when installation failed, replacing it with the actual error.

Patch Changes

• #16105 23d60de Thanks @matthewp! - Fix dev toolbar audit crash when encountering the image ARIA role

• #16089 999c875 Thanks @martrapp! - Fixes an issue with the client router where Vue's :deep() notation was ignored in dev mode.

Minor Changes

• #15804 a5e7232 Thanks @merlinnot! - Allows setting codec-specific defaults for Astro's built-in Sharp image service via image.service.config.

  You can now configure encoder-level options such as jpeg.mozjpeg, webp.effort, webp.alphaQuality, avif.effort, avif.chromaSubsampling, and png.compressionLevel when using astro/assets/services/sharp for compile-time image generation.

  These settings apply as defaults for the built-in Sharp pipeline, while per-image quality still takes precedence when set on <Image />, <Picture />, or getImage().

• #15455 babf57f Thanks @AhmadYasser1! - Adds fallbackRoutes to the IntegrationResolvedRoute type, exposing i18n fallback routes to integrations via the astro:routes:resolved hook for projects using fallbackType: 'rewrite'.

  This allows integrations such as the sitemap integration to properly include generated fallback routes in their output.

  {
    'astro:routes:resolved': ({ routes }) => {
      for (const route of routes) {
        for (const fallback of route.fallbackRoutes) {
          console.log(fallback.pathname) // e.g. /fr/about/
        }
      }
    }
  }

• #15340 10a1a5a Thanks @trueberryless! - Adds support for advanced configuration of SmartyPants in Markdown.

  You can now pass an options object to markdown.smartypants in your Astro configuration to fine-tune how punctuation, dashes, and quotes are transformed.

  This is helpful for projects that require specific typographic standards, such as "oldschool" dash handling or localized quotation marks.

  // astro.config.mjs
  export default defineConfig({
    markdown: {
      smartypants: {
        backticks: 'all',
        dashes: 'oldschool',
        ellipses: 'unspaced',
        openingQuotes: { double: '«', single: '‹' },
        closingQuotes: { double: '»', single: '›' },
        quotes: false,
      },
    },
  });

  See the retext-smartypants options for more information.

Patch Changes

• #16025 a09f319 Thanks @koji-1009! - Instructs the client router to skip view transition animations when the browser is already providing its own visual transition, such as a swipe gesture.

• #16055 ccecb8f Thanks @Gautam-Bharadwaj! - Fixes an issue where client:only components could have duplicate client:component-path attributes added in MDX in rare cases

• #16081 44fc340 Thanks @crazylogic03! - Fixes the emitFile() is not supported in serve mode warning that appears during astro dev when using integrations that inject before-hydration scripts (e.g. @astrojs/react)

• #16068 31d733b Thanks @Karthikeya1500! - Fixes the dev toolbar a11y audit incorrectly classifying menuitemradio as a non-interactive ARIA role.

• #16080 e80ac73 Thanks @ematipico! - Fixes experimental.queuedRendering incorrectly escaping the HTML output of .html page files, causing the page content to render as plain text instead of HTML in the browser.

• #16048 13b9d56 Thanks @matthewp! - Fixes a dev server crash (serverIslandNameMap.get is not a function) that occurred when navigating to a page with server:defer after first visiting a page without one, when using @astrojs/cloudflare

• #16093 336e086 Thanks @Snugug! - Fixes Zod meta not correctly being rendered on top-level schema when converted into JSON Schema

• #16043 d402485 Thanks @ematipico! - Fixes checkOrigin CSRF protection in astro dev behind a TLS-terminating reverse proxy. The dev server now reads X-Forwarded-Proto (gated on security.allowedDomains, matching production behaviour) so the constructed request origin matches the https:// origin the browser sends. Also ensures security.allowedDomains and security.checkOrigin are respected in dev.

• #16064 ba58e0d Thanks @ematipico! - Updates the dependency svgo to the latest, to fix a security issue.

• #16007 2dcd8d5 Thanks @florian-lefebvre! - Fixes a case where fonts files would unecessarily be copied several times during the build

• #16017 b089b90 Thanks @felmonon! - Fix the astro sync error message when getImage() is called while loading content collections.

• #16054 f74465a Thanks @seroperson! - Fixes an issue with the development server, where changes to the middleware weren't picked, and it required a full restart of the server.

• #16033 198d31b Thanks @adampage! - Fixes a bug where the the role image was incorrectly reported by audit tool bar.

• #15935 278828c Thanks @oliverlynch! - Fixes cached assets failing to revalidate due to redirect check mishandling Not Modified responses.

• #16075 2c1ae85 Thanks @florian-lefebvre! - Fixes a case where invalid URLs would be generated in development when using font families with an oblique style and angles

• #16062 87fd6a4 Thanks @matthewp! - Warns on dev server startup when Vite 8 is detected at the top level of the user's project, and automatically adds a "overrides": { "vite": "^7" } entry to package.json when running astro add cloudflare. This prevents a require_dist is not a function crash caused by a Vite version split between Astro (requires Vite 7) and packages like @tailwindcss/vite that hoist Vite 8.

• Updated dependencies []:

  • @astrojs/underscore-redirects@1.0.2

Minor Changes

• #15862 06fba3a Thanks @crutchcorn! - Adds support for passing a Babel config to the Preact Vite Plugin:

  import preact from '@astrojs/preact';
  
  export default defineConfig({
    integrations: [
      preact({
        babel: {
          generatorOpts: {
            importAttributesKeyword: 'with',
          },

    ],
  });

Minor Changes

• #15340 10a1a5a Thanks @trueberryless! - Updates createMarkdownProcessor to support advanced SmartyPants options.

  import { createMarkdownProcessor } from '@astrojs/markdown-remark';
  
  const processor = await createMarkdownProcessor({
    smartypants: {
      backticks: 'all',
      dashes: 'oldschool',
      ellipses: 'unspaced',
      openingQuotes: { double: '«', single: '‹' },
      closingQuotes: { double: '»', single: '›' },
      quotes: false,
    },
  });

• #15941 f41584a Thanks @ematipico! - Fixes an infinite loop in resolveClientDir() when the server entry point is bundled with esbuild or similar tools. The function now throws a descriptive error instead of hanging indefinitely when the expected server directory segment is not found in the file path.

Patch Changes

• #3759 f24ce99 Thanks @MilesChou! - Fixes an issue where monolingual sites using a region-specific locale (e.g., zh-TW) as the default would incorrectly display base language translations (e.g., zh Simplified Chinese) instead of the region-specific ones (e.g., zh-TW Traditional Chinese).

• #16011 e752170 Thanks @matthewp! - Fixes a dev server hang on the first request when using the Cloudflare adapter

• #15997 1fddff7 Thanks @ematipico! - Fixes Astro.rewrite() failing when the target path contains duplicate slashes (e.g. //about). The duplicate slashes are now collapsed before URL parsing, preventing them from being interpreted as a protocol-relative URL.

  When using the middleware handler, requests that were being passed on to Express / Fastify (e.g. static files / pre-rendered pages / etc.) weren't cleaning up socket listeners before calling next(), causing a memory leak warning. This fix makes sure to run the cleanup before calling next().

Patch Changes

Minor Changes

• #3644 0d2e7ed Thanks @HiDeoo! - ⚠️ BREAKING CHANGE: The minimum supported version of Starlight is now 0.38.0

Minor Changes

• #3644 0d2e7ed Thanks @HiDeoo! - Adds support for Astro v6, drops support for Astro v5.

  Upgrade Astro and dependencies

  ⚠️ BREAKING CHANGE: Astro v5 is no longer supported. Make sure you update Astro and any other official integrations at the same time as updating Starlight:

  npx @astrojs/upgrade

  Community Starlight plugins and Astro integrations may also need to be manually updated to work with Astro v6. If you encounter any issues, please reach out to the plugin or integration author to see if it is a known issue or if an updated version is being worked on.

  Update your collections

  ⚠️ BREAKING CHANGE: Drops support for content collections backwards compatibility.

  In Astro 5.x, projects could delay upgrading to the new Content Layer API introduced for content collections because of some existing automatic backwards compatibility that was not previously behind a flag. This meant that it was possible to upgrade from Astro 4 to Astro 5 without updating your content collections, even if you had not enabled the legacy.collections flag. Projects would continue to build, and no errors or warnings would be displayed.

  Astro v6.0 now removes this automatic legacy content collections support, along with the legacy.collections flag.

  If you experience content collections errors after updating to v6, check your project for any removed legacy features that may need updating to the Content Layer API. See the Starlight v0.30.0 upgrade guide for detailed instructions on upgrading legacy collections to the new Content Layer API.

  If you are unable to make any changes to your collections at this time, including Starlight's default docs and i18n collections, you can enable the legacy.collectionsBackwardsCompat flag to upgrade to v6 without updating your collections. This temporary flag preserves some legacy v4 content collections features, and will allow you to keep your collections in their current state until the legacy flag is no longer supported.

• #3704 375edcc Thanks @florian-lefebvre! - Fixes autocomplete for components exported from @astrojs/starlight/components/*

  ⚠️ Potentially breaking change: This change moves some files used in Starlight’s component internals out of the components/ directory. Direct use of these files was not and is not officially supported. If you previously imported TableOfContents/starlight-toc.ts, TableOfContents/TableOfContentsList.astro, Icons.ts, or SidebarPersistState.ts, please review your code when updating.

• #3729 3642625 Thanks @delucis! - Improves Starlight’s default body font stack to better support languages such as Chinese, Japanese, and Korean on Windows.
  For most users there should be no visible change.

  If you would prefer to keep the previous font stack, you can add the following custom CSS to your site:

  :root {
    --sl-font-system: ui-sans-serif, system-ui, 'Segoe UI', Roboto,
      'Helvetica Neue', Arial, 'Noto Sans', sans-serif, 'Apple Color Emoji',
      'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji';
  }

• #3598 fff38d5 Thanks @HiDeoo! - Makes hover styles consistent in Starlight’s navigation bar

  Previously, the social icon links and language/theme switchers in Starlight’s navigation bar, dimmed on hover.
  After this change, they now increase in contrast on hover instead.
  This matches hover behavior elsewhere, for example in the sidebar, table of contents, or search button.

  ⚠️ Potentially breaking change: this is a subtle change to the hover style colors.
  If you want to preserve the previous styling, you can add the following custom CSS to your site:

  starlight-theme-select label,
  starlight-lang-select label {
    color: var(--sl-color-gray-1);
  
    &:hover {
      color: var(--sl-color-white);
    }
  }
  
  .social-icons a:hover {
    color: var(--sl-color-text-accent);
    opacity: 0.66;
  }

Minor Changes

• #15778 4ebc1e3 Thanks @ematipico! - Added a new entry point called /request, which exposes utilities to work with the Request type:

  • getFirstForwardedValue: retrieves the first value of a multi-value header.
  • isValidIpAddress: checks whether a string contains only characters valid in IPv4/IPv6 addresses.
  • getValidatedIpFromHeader: extracts the first value from a header and validates it as an IP address.
  • getClientIpAddress: retrieves and validates the first IP from the x-forwarded-for header.

• #15077 a164c77 Thanks @matthewp! - Adds normalizePathname() utility function for normalizing URL pathnames to match the canonical form used by route generation.

• #15726 6f19ecc Thanks @ocavue! - Updates dependency shiki to v4

  Check Shiki's upgrade guide.

Minor Changes

• #15277 cb99214 Thanks @ematipico! - Fixes an issue where the function createShikiHighlighter would always create a new Shiki highlighter instance. Now the function returns a cached version of the highlighter based on the Shiki options. This should improve the performance for sites that heavily rely on Shiki and code in their pages.

• #15332 7c55f80 Thanks @matthewp! - Exposes the fileURL option in MarkdownProcessorRenderOptions, allowing callers to specify the file URL for resolving relative image paths.

Minor Changes

• #14494 727b0a2 Thanks @florian-lefebvre! - Updates Markdown heading ID generation - (v6 upgrade guidance)

• #15345 840fbf9 Thanks @matthewp! - Uses Astro's new emitClientAsset API for image emission in content collections

• #15097 be1b9bf Thanks @matthewp! - Updates internal image processing to be compatible with Astro 6. This change is internal-only and does not affect the public API.

  The integration now uses Astro's new emitImageMetadata() function instead of the removed emitESMImage() function for processing images referenced in Markdoc content during build time. This ensures continued compatibility with Astro's asset processing pipeline while maintaining the same behavior for users.

Patch Changes

• #15184 f47c071 Thanks @ematipico! - Fixes an issue where the package wasn't correctly published

• #15457 6e8da44 Thanks @AhmadYasser1! - Fixes custom attributes on Markdoc's built-in {% table %} tag causing "Invalid attribute" validation errors.

  In Markdoc, table exists as both a tag ({% table %}) and a node (the inner table structure). When users defined custom attributes on either nodes.table or tags.table, the attributes weren't synced to the counterpart, causing validation to fail on whichever side was missing the declaration.

  The fix automatically syncs custom attribute declarations between tags and nodes that share the same name, so users can define attributes on either side and have them work correctly.

• #15264 11efb05 Thanks @florian-lefebvre! - Lower the Node version requirement to allow running on Stackblitz until it supports v22

• #15335 75931c2 Thanks @matthewp! - Fixes an issue where spreading a built-in Markdoc node config (e.g., ...Markdoc.nodes.fence) and specifying a custom render component would not work because the built-in transform() function was overriding the custom component. Now, render wins over transform when both are specified.
