Minor Changes

• #​3618 dcf6d09 Thanks @​HiDeoo! - ⚠️ BREAKING CHANGE: This release changes how autogenerated links work in Starlight’s sidebar configuration.

  If you have sidebar groups using the autogenerate key, you must now wrap that configuration in an items array:

  {
      label: 'My group',
  -   autogenerate: { directory: 'some-dir' },
  +   items: [{ autogenerate: { directory: 'some-dir' } }],
  }

  This change unlocks the possibility to mix autogenerated links and other links in a single group, for example:

  {
    label: 'Mixed group',
    items: [
      'example-page',
      { autogenerate: { directory: 'examples' } },
      { label: 'More examples', link: 'https://example.com' },
    ],
  }

  This release also updates the shape of autogenerated sidebar entries in route data. Autogenerated links and groups in Astro.locals.starlightRoute.sidebar now include an autogenerate object with the configured directory value:

  {
    type: 'link',
    label: 'Example',
    href: '/examples/example/',
    isCurrent: false,
    autogenerate: { directory: 'examples' }
  }

• #​3618 dcf6d09 Thanks @​HiDeoo! - ⚠️ BREAKING CHANGE: This release changes the default collapsed state of autogenerated sidebar subgroups.

  Autogenerated subgroups no longer inherit the collapsed value from their parent group. They are now expanded by default unless explicitly configured with autogenerate.collapsed.

  If your sidebar configuration relies on a collapsed parent group to also collapse its autogenerated subgroups, update your configuration to set autogenerate.collapsed to true:

  {
    label: 'Reference',
    collapsed: true,
    items: [
  -   { autogenerate: { directory: 'reference' } },
  +   { autogenerate: { directory: 'reference', collapsed: true } },
    ],
  }

• #​3845 4d755f5 Thanks @​delucis! - Adds a <link rel="alternate" hreflang="x-default" href="..."> tag pointing to the default locale in multilingual sites. The x-default alternate is used as a signal of which language to fall back to if no other is available. Learn more in Google’s SEO localization docs.

• #​3862 ec70630 Thanks @​itrew! - Makes spacing of items in nested lists more consistent

• #​3872 417a66c Thanks @​tats-u! - Enables the CSS property text-autospace in Chinese and Japanese documents.

  If you would prefer to disable autospacing in Chinese and Japanese pages, you can add the following custom CSS to your site:

  [lang]:where(:lang(zh, ja)) {
    text-autospace: initial;
  }

• #​3797 9764ebd Thanks @​delucis! - Avoids the risk of layout shift when users expand and collapse sidebar groups

  This release can introduce additional padding to the site sidebar on certain devices to reserve space for scrollbars. You may wish to inspect your site sidebar visually when upgrading.

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

  .sidebar-pane {
    scrollbar-gutter: auto;
  }

Minor Changes

• #​16366 d69f858 Thanks @​matthewp! - Adds a new experimental.advancedRouting option that lets you take full control of Astro's request handling pipeline by creating a src/app.ts file in your project.

  Today, Astro handles every incoming request through a fixed internal pipeline: trailing slash normalization, redirects, actions, middleware, page rendering, i18n, and so on. That pipeline works great for most sites, but as projects grow you often want to run your own logic between those steps — an auth check before rendering, a rate limiter before actions, custom logging around the whole stack. Advanced routing gives you that control.

  When enabled, Astro looks for a src/app.ts file in your project. If it finds one, that file becomes the entrypoint for all server-rendered requests. You compose the pipeline yourself using the handlers Astro provides, and you can slot your own logic anywhere in the chain.

Enabling advanced routing

// astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  experimental: {
    advancedRouting: true,
  },
});

Two ways to build your pipeline

Astro ships two entrypoints for advanced routing: astro/fetch and astro/hono.

astro/fetch is a low-level, framework-free API built on the Web Fetch standard. You create a FetchState from the incoming request, then call handler functions in sequence. Each handler takes the state, does its work, and returns a Response (or undefined to pass through). This is the core primitive that everything else is built on:

// src/app.ts
import {
  FetchState,
  trailingSlash,
  redirects,
  actions,
  middleware,
  pages,
  i18n,
} from 'astro/fetch';

export default {
  async fetch(request: Request) {
    const state = new FetchState(request);

    // Early exits — these return a Response only when they apply.
    const slash = trailingSlash(state);
    if (slash) return slash;

    const redirect = redirects(state);
    if (redirect) return redirect;

    const action = await actions(state);
    if (action) return action;

    // Middleware wraps page rendering; i18n post-processes the response.
    const response = await middleware(state, () => pages(state));
    return i18n(state, response);
  },
};

astro/hono wraps the same handlers as Hono middleware, so you can mix Astro's pipeline with Hono's ecosystem of middleware (logger, CORS, JWT, rate limiting, etc.) using the app.use() pattern you already know:

// src/app.ts
import { Hono } from 'hono';
import { getCookie } from 'hono/cookie';
import { logger } from 'hono/logger';
import { actions, middleware, pages, i18n } from 'astro/hono';

const app = new Hono();

app.use(logger());

// Auth gate — only runs for /dashboard routes.
app.use('/dashboard/*', async (c, next) => {
  const session = getCookie(c, 'session');
  if (!session) return c.redirect('/login');
  return next();
});

app.use(actions());
app.use(middleware());
app.use(pages());
app.use(i18n());

export default app;

Both approaches give you the same power — pick whichever fits your project. If you don't need a framework, astro/fetch keeps things minimal. If you want a rich middleware ecosystem, astro/hono gets you there with one import.

For more information on enabling and using this feature in your project, see the experimental advanced routing docs. To give feedback, or to keep up with its development, see the advanced routing RFC for more information and discussion.

• #​16366 d69f858 Thanks @​matthewp! - Adds a consume() instance method to AstroCookies. This method marks the cookies as consumed and returns the Set-Cookie header values. After consumption, any subsequent set() calls will log a warning, since the headers have already been sent.

  Previously this was only available as a static method AstroCookies.consume(cookies). The static method is now deprecated but kept for backward compatibility with existing adapters.

• #​16412 ba2d2e3 Thanks @​0xbejaxer! - Add retry and error event handling for astro-island hydration import failures to reduce unrecoverable hydration errors on transient network failures.

• #​16582 885cd31 Thanks @​Princesseuh! - Adds a new image.dangerouslyProcessSVG flag to optionally enable processing SVG inputs. For security reasons, Astro will no longer rasterizes SVG image sources by default in its default image service and endpoint.

  Set image.dangerouslyProcessSVG: true to opt back into processing SVG inputs.

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    // ...
    image: {
      dangerouslyProcessSVG: true,
    },
  });

  Note that this is a breaking change for users who were previously relying on Astro's default image service to rasterize SVG inputs, but it is a necessary change to improve security and prevent potential vulnerabilities.

• #​16519 1b1c218 Thanks @​louisescher! - Adds support for redirecting URLs in remote image optimization.

  Previously, when a remote image URL meant to be optimized by Astro led to a redirect, Astro would fail silently and ignore the redirect. Now, Astro tracks up to 10 redirects for these images. If any of the redirects are not covered by a pattern in image.remotePatterns or a domain in image.domains, Astro will fail with a helpful error message.

  In the following example, the first image would be loaded successfully, while the second would lead to Astro throwing an error:

  export default defineConfig({
    image: {
      domains: ['example.com', 'cdn.example.com'],
    },
  });

  {
    /* Redirects to https://cdn.example.com/assets/image.png: */
  }
  <Image
    src="https://example.com/assets/image.png"
    width="1920"
    height="1080"
    alt="An example image."
  />;
  
  {
    /* Redirects to https://malicious.com/image.png: */
  }
  <Image
    src="https://example.com/bad-image.png"
    width="1920"
    height="1080"
    alt="An example image."
  />;

  In cases where all redirects to HTTPS hosts should be trusted, the following configuration for image.remotePatterns can be used:

  export default defineConfig({
    image: {
      remotePatterns: [
        {
          protocol: 'https',
        },
      ],
    },
  });

Patch Changes

• #​16592 9c6efc5 Thanks @​matthewp! - Escapes interpolated values in the dev server redirect HTML template, consistent with how the 404 template already handles them

• #​16585 78f305e Thanks @​web-dev0521! - Fixes z.array(z.boolean()) in form actions incorrectly coercing the string "false" to true. Boolean array elements now use the same 'true'/'false' string comparison as single z.boolean() fields, so submitting ["false", "true", "false"] correctly parses as [false, true, false].

• #​16567 12a03f2 Thanks @​matthewp! - Fixes deleted content collection entries persisting in getCollection() results during dev

• #​16595 ce9b25c Thanks @​web-dev0521! - Fixes pushDirective in the CSP runtime duplicating the new directive once per existing non-matching directive. Calling insertDirective() (or otherwise pushing a directive whose name is not yet in the list) now appends it exactly once, and a directive that merges with a later existing entry no longer leaves an unmerged copy behind.

• #​16600 94e4b7c Thanks @​web-dev0521! - Fixes Astro.preferredLocale returning the wrong value when i18n.locales mixes object-form entries ({ path, codes }) with string entries that normalize to the same locale. The first matching code in the configured locales order is now selected, matching the documented behavior.

• #​16591 cce20f7 Thanks @​matthewp! - Uses a consistent generic error message in the image endpoint across all adapters

• #​16629 f54be80 Thanks @​g-taki! - Fixes a bug where SSR responses in astro dev could crash with TypeError: this.logger.flush is not a function.

• #​16589 3740b24 Thanks @​ArmandPhilippot! - Fixes an outdated code snippet in the documentation for session storage configuration.

Patch Changes

• #​16292 00f48ee Thanks @​p-linnane! - Fixes head metadata propagation in dev for adapters that load modules in the prerender Vite environment, such as @astrojs/cloudflare. The astro:head-metadata plugin previously only tracked the ssr environment, so maybeRenderHead() could fire inside an unrelated component's <template> element, trapping subsequent hoisted <style> blocks.

• #​16451 778865f Thanks @​maximslo! - Fixes build crash when processing animated AVIF images. Sharp now gracefully passes through unsupported image formats instead of crashing during the build.

• #​16548 7214d3e Thanks @​senutpal! - Fixes scoped styles applying to the wrong element when vite.css.transformer is set to 'lightningcss' and a selector uses a nested & inside :where(...), such as Tailwind v4's space-x-*, space-y-*, and divide-* utilities.

• #​16566 9ac96b4 Thanks @​web-dev0521! - Fixes data-astro-prefetch="tap" not triggering when clicking nested elements (e.g. <span>, <img>, <svg>) inside an anchor tag.

• #​15994 1e70d18 Thanks @​ossaidqadri! - Fix <style> compilation failure when importing Astro components via tsconfig path aliases

• #​16144 1cd6650 Thanks @​fkatsuhiro! - Fixed a regression where .html was unexpectedly stripped from dynamic route parameters on non-page routes (.ts endpoints and redirects). This caused endpoints like /some/[...id].ts returning id: 'file.html' on getStaticPaths to not serve that file because the generated route (/some/file.html) would get matched as id: file that is not part of the list returned by getStaticPaths.

• #​16415 559c0fd Thanks @​0xbejaxer! - Fix CSS traversal boundaries so pages with export const partial = true still contribute styles when imported as components by other pages.

• #​16516 17f1867 Thanks @​fkatsuhiro! - Fixes an issue where the index route would return a 404 error when using a custom base path combined with trailingSlash: 'never'. This ensures that the home page and internal rewrites are correctly matched under these configurations.

• #​16515 280ec88 Thanks @​jp-knj! - Fixes an issue where i18n.fallback pages with fallbackType: 'rewrite' were emitted with empty bodies during astro build.

• #​16565 7959798 Thanks @​enjoyandlove! - Fixes session persistence when session.delete() is the first mutation in a request (no prior get, set, has, or keys). The session was marked dirty in memory, but persistence skipped the save because #data stayed undefined, so the backing store could still return the deleted key on the next request.

• #​16527 86fd80d Thanks @​enjoyandlove! - Prevents script deduplication state from being consumed while rendering inert <template> contexts.

• #​16540 e59c637 Thanks @​ascorbic! - Skips session storage reads when no session cookie is present. Previously, calling session.get() on a request without a session cookie would initialize the storage driver and make a read that was guaranteed to miss. On network-backed drivers this added latency and resource usage to every anonymous request.

• #​16517 6ab0b3c Thanks @​adamchal! - Removes inline CSS for prerendered routes from the SSR manifest. The static HTML on disk already inlines those styles, and the SSR worker never renders prerendered routes, so the data was dead weight. Builds with many prerendered routes and build.inlineStylesheets: "always" (or "auto" with small stylesheets) will see a smaller SSR entry chunk, which reduces cold-start parse time on platforms like Cloudflare Workers.

• #​16509 d3d3557 Thanks @​cyphercodes! - Fix conditional named slot callbacks receiving arguments from Astro.slots.render().

• #​16236 c6b068e Thanks @​fkatsuhiro! - Fixes the position prop on <Image /> and <Picture /> components to correctly apply object-position styles

• #​16018 d14f47c Thanks @​felmonon! - Fix defineLiveCollection() so LiveLoader data types declared as interfaces are accepted.
