    It is now possible to opt into using Astro’s 6.4 Sätteri Markdown processor by installing the @astrojs/markdown-satteri package and configuring it in your astro.config.mjs file:

  🍿 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;
    }

  • #3858 6672c35 Thanks @delucis! - Updates i18next, used for Starlight’s localization APIs, from v23 to v26

  🍿 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;
    }

  • #3675 0ba556d Thanks @controversial! - Excludes the accessible labels for heading anchor links from Pagefind results
• 0.37.4

  Jan 23, 2026

  🐞 Patch Changes

  • #3534 703fab0 Thanks @HiDeoo! - Fixes support for running builds when npx is unavailable.

    Previously, Starlight would spawn a process to run the Pagefind search indexing binary using npx. On platforms where npx isn’t available, this could cause issues. Starlight now runs Pagefind using its Node.js API to avoid a separate process. As a side effect, you may notice that logging during builds is now less verbose.
