Patch Changes

• #16889 b94bcfd Thanks @​Princesseuh! - Fixes a plugins is not iterable crash when using a pre-6.0 @astrojs/mdx alongside integrations (e.g. Starlight) that set markdown.remarkPlugins, markdown.rehypePlugins, or markdown.remarkRehype.

• #16878 b9f6bb9 Thanks @​fkatsuhiro! - Fixes an issue where on-demand (SSR) dynamic routes would return 404 when a prerendered dynamic route with the same URL pattern was sorted first alphabetically. In production builds with @astrojs/node adapter, if [a_prebuild].astro (prerender=true) came before [b_ssr].astro alphabetically, requests to URLs not in the prerendered route's static paths would 404 instead of falling through to the SSR route. The fix adds fallthrough logic so that when a prerendered dynamic route matches but can't serve the request, Astro tries subsequent matching routes.

Minor Changes

• #16468 4cff3a1 Thanks @​matthewp! - Adds a new preserveBuildServerDir adapter feature

  Adapters can now set preserveBuildServerDir: true in their adapter features to keep the dist/server/ directory structure for static builds, mirroring the existing preserveBuildClientDir option. This is useful for adapters that require a consistent dist/client/ and dist/server/ layout regardless of build output type.

  setAdapter({
    name: 'my-adapter',
    adapterFeatures: {
      buildOutput,
      preserveBuildClientDir: true,
      preserveBuildServerDir: true,
    },
  });

• #16848 f732f3c Thanks @​Princesseuh! - Adds a new markdown.processor configuration option, allowing you to choose an alternative Markdown processor.

  Websites with many Markdown/MDX files tend to be slow to build because the unified ecosystem (e.g., remark, rehype) is slow to process. This feature introduces the ability to replace this part of the build pipeline with another processor.

  The default processor is unified(). This means that existing configurations remain unchanged and your remark/rehype plugins continue to work.

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { unified } from '@astrojs/markdown-remark';
  import remarkToc from 'remark-toc';
  export default defineConfig({
  markdown: {
  processor: unified({
  remarkPlugins: [remarkToc],
  }),
  },
  });

  In addition to this new configuration option, Astro provides a new alternative processor based on Rust: Sätteri. You can choose to use it now by installing @astrojs/markdown-satteri, importing the satteri() processor, and adapting your existing configuration:

  // astro.config.mjs

Patch Changes

• #16883 eeb064c Thanks @​Princesseuh! - Restores the astro/jsx/rehype.js entry point so that older versions of @astrojs/mdx continue to work when used with Astro 6.x. This entry point will be removed in Astro 7.0.
