##### [v7.0.0](https://github.com/withastro/astro/blob/HEAD/packages/integrations/mdx/CHANGELOG.md#700)

##### Major Changes

- [#15819](withastro/astro#15819) [`cafec4e`](withastro/astro@cafec4e) Thanks [@delucis](https://github.com/delucis)! - Upgrade to Vite v8

##### Minor Changes

- [#17093](withastro/astro#17093) [`4585fe5`](withastro/astro@4585fe5) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Replaces the import entrypoint of `getContainerRenderer()`

  A new `container-renderer` entrypoint exporting `getContainerRenderer()` has been added to the following integrations: React, Preact, Svelte, SolidJS, Vue, and MDX. This prevents bundlers from trying to bundle unrelated exports from the package root when only the Container API is used.

  If you are using the Container API, update your import statements to use the new entrypoint. The following example updates the `getContainerRenderer()` import for React:

  ```diff
  - import { getContainerRenderer } from '@astrojs/react';
  + import { getContainerRenderer } from '@astrojs/react/container-renderer';
  ```

  Importing `getContainerRenderer()` from the package root still works, but is now deprecated and logs a warning.

- [#17129](withastro/astro#17129) [`ff7b718`](withastro/astro@ff7b718) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds support for [modifying frontmatter programmatically](https://docs.astro.build/en/guides/markdown-content/#modifying-frontmatter-programmatically) with the default Markdown processor.

  A Sätteri plugin can now read and mutate `ctx.data.astro.frontmatter`, and Astro uses the result as the page's frontmatter, in both Markdown and MDX.

##### Patch Changes

- [#17124](withastro/astro#17124) [`7e7ab87`](withastro/astro@7e7ab87) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Updates `satteri` to `0.9.0`. See the [Sätteri changelog](https://github.com/bruits/satteri/blob/main/packages/satteri/CHANGELOG.md) for details.

- [#17027](withastro/astro#17027) [`241250b`](withastro/astro@241250b) Thanks [@ocavue](https://github.com/ocavue)! - Triggers beta prereleases for packages that are still on alpha

- [#16969](withastro/astro#16969) [`4a31f90`](withastro/astro@4a31f90) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds support for Prism syntax highlighting to the Sätteri Markdown and MDX processors. Setting `markdown.syntaxHighlight` to `'prism'` now highlights your code blocks with Prism.

  ```js
  // astro.config.mjs
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri(),
      syntaxHighlight: 'prism',
    },
  });

##### Major Changes

- [#16848](withastro/astro#16848) [`f732f3c`](withastro/astro@f732f3c) Thanks [@Princesseuh](https://github.com/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.

  ```js
  // 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](https://satteri.bruits.org/). You can choose to use it now by installing `@astrojs/markdown-satteri`, importing the `satteri()` processor, and adapting your existing configuration:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
  });
  ```

  This processor does not support the remark and rehype plugins. This means you may need to convert them to [MDAST or HAST plugins](https://satteri.bruits.org/docs/plugins/) to retain your current functionality.

  The existing top-level `markdown.remarkPlugins`, `markdown.rehypePlugins`, `markdown.remarkRehype`, `markdown.gfm`, and `markdown.smartypants` options still work, but are now deprecated and will be removed in a future major update. The matching `remarkPlugins`, `rehypePlugins`, and `remarkRehype` options on the MDX integration are also deprecated for the same reason. To anticipate their removal, move them onto `unified({...})` (or your preferred plugin processor) :

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import remarkToc from 'remark-toc';
  import rehypeSlug from 'rehype-slug';
  + import { unified } from '@astrojs/markdown-remark';

  export default defineConfig({
    markdown: {
  +    processor: unified({
  +      remarkPlugins: [remarkToc],
  +      rehypePlugins: [rehypeSlug],
  +      remarkRehype: true,
  +      gfm: true,
  +      smartypants: true,
  +    }),
  -    remarkPlugins: [remarkToc],
  -    rehypePlugins: [rehypeSlug],
  -    remarkRehype: true,
  -    gfm: true,
  -    smartypants: true,
    },
  });
  ```

  For more information on enabling and using this feature in your project, see our [Markdown guide](https://docs.astro.build/en/guides/markdown-content/). To give feedback on this new Rust processor, see the [Native Markdown / MDX parsing and processing RFC](withastro/roadmap#1364).

##### Minor Changes

- [#16848](withastro/astro#16848) [`f732f3c`](withastro/astro@f732f3c) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds support for using [`@astrojs/markdown-satteri`](https://www.npmjs.com/package/@astrojs/markdown-satteri) to parse `.mdx` files.

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [mdx()],
  });
  ```

  Note that the [`recmaPlugins` option](https://docs.astro.build/en/guides/integrations-guide/mdx/#recmaplugins) is not supported when using Sätteri as your MDX processor. If you would like to use Sätteri for Markdown files, but still use Unified for MDX, you can pass a different Markdown processor to the MDX integration:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';
  import { unified } from '@astrojs/markdown-remark';
  import myPlugin from './my-recma-plugin.js';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [
      mdx({
        recmaPlugins: [myPlugin],
        processor: unified(),
      }),
    ],
  });
  ```

##### Minor Changes

- [#17093](withastro/astro#17093) [`4585fe5`](withastro/astro@4585fe5) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Replaces the import entrypoint of `getContainerRenderer()`

  A new `container-renderer` entrypoint exporting `getContainerRenderer()` has been added to the following integrations: React, Preact, Svelte, SolidJS, Vue, and MDX. This prevents bundlers from trying to bundle unrelated exports from the package root when only the Container API is used.

  If you are using the Container API, update your import statements to use the new entrypoint. The following example updates the `getContainerRenderer()` import for React:

  ```diff
  - import { getContainerRenderer } from '@astrojs/react';
  + import { getContainerRenderer } from '@astrojs/react/container-renderer';
  ```

  Importing `getContainerRenderer()` from the package root still works, but is now deprecated and logs a warning.

##### Major Changes

- [#16848](withastro/astro#16848) [`f732f3c`](withastro/astro@f732f3c) Thanks [@Princesseuh](https://github.com/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.

  ```js
  // 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](https://satteri.bruits.org/). You can choose to use it now by installing `@astrojs/markdown-satteri`, importing the `satteri()` processor, and adapting your existing configuration:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
  });
  ```

  This processor does not support the remark and rehype plugins. This means you may need to convert them to [MDAST or HAST plugins](https://satteri.bruits.org/docs/plugins/) to retain your current functionality.

  The existing top-level `markdown.remarkPlugins`, `markdown.rehypePlugins`, `markdown.remarkRehype`, `markdown.gfm`, and `markdown.smartypants` options still work, but are now deprecated and will be removed in a future major update. The matching `remarkPlugins`, `rehypePlugins`, and `remarkRehype` options on the MDX integration are also deprecated for the same reason. To anticipate their removal, move them onto `unified({...})` (or your preferred plugin processor) :

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import remarkToc from 'remark-toc';
  import rehypeSlug from 'rehype-slug';
  + import { unified } from '@astrojs/markdown-remark';

  export default defineConfig({
    markdown: {
  +    processor: unified({
  +      remarkPlugins: [remarkToc],
  +      rehypePlugins: [rehypeSlug],
  +      remarkRehype: true,
  +      gfm: true,
  +      smartypants: true,
  +    }),
  -    remarkPlugins: [remarkToc],
  -    rehypePlugins: [rehypeSlug],
  -    remarkRehype: true,
  -    gfm: true,
  -    smartypants: true,
    },
  });
  ```

  For more information on enabling and using this feature in your project, see our [Markdown guide](https://docs.astro.build/en/guides/markdown-content/). To give feedback on this new Rust processor, see the [Native Markdown / MDX parsing and processing RFC](withastro/roadmap#1364).

##### Minor Changes

- [#16848](withastro/astro#16848) [`f732f3c`](withastro/astro@f732f3c) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds support for using [`@astrojs/markdown-satteri`](https://www.npmjs.com/package/@astrojs/markdown-satteri) to parse `.mdx` files.

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [mdx()],
  });
  ```

  Note that the [`recmaPlugins` option](https://docs.astro.build/en/guides/integrations-guide/mdx/#recmaplugins) is not supported when using Sätteri as your MDX processor. If you would like to use Sätteri for Markdown files, but still use Unified for MDX, you can pass a different Markdown processor to the MDX integration:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';
  import { unified } from '@astrojs/markdown-remark';
  import myPlugin from './my-recma-plugin.js';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [
      mdx({
        recmaPlugins: [myPlugin],
        processor: unified(),
      }),
    ],
  });
  ```

- [#17262](withastro/astro#17262) [`f8e9458`](withastro/astro@f8e9458) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Moves MDX file processing to the Markdown processors.

  '[@astrojs/mdx](https://github.com/astrojs/mdx)' is still required to add MDX support to your project. However, it now delegates the MDX files processing to Markdown processors.

##### What should I do?

If you haven't explicitly installed a Markdown processor, you don't need to do anything.

Otherwise, ensure that your configured Markdown processor uses the following version:

- `@astrojs/markdown-satteri` 0.4.0 or later if you use `satteri()`
- `@astrojs/markdown-remark` 7.3.0 or later if you use `unified()`

##### Patch Changes

- [#17262](withastro/astro#17262) [`f8e9458`](withastro/astro@f8e9458) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixes `.mdx` files still using `markdown.processor` when `extendMarkdownConfig` is `false`. They now use a clean default processor instead; pass `mdx({ processor })` to choose one explicitly.

- [#17262](withastro/astro#17262) [`f8e9458`](withastro/astro@f8e9458) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds a warning when the deprecated `remarkPlugins`, `rehypePlugins`, `recmaPlugins` and `remarkRehype` options are ignored because your Markdown processor does not run them. They still apply when your processor is `unified()`, and were previously dropped silently otherwise.

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

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
  });
  ```

  This processor does not support the remark and rehype plugins. This means you may need to convert them to [MDAST or HAST plugins](https://satteri.bruits.org/docs/plugins/) to retain your current functionality.

  The existing top-level `markdown.remarkPlugins`, `markdown.rehypePlugins`, `markdown.remarkRehype`, `markdown.gfm`, and `markdown.smartypants` options still work, but are now deprecated and will be removed in a future major update. The matching `remarkPlugins`, `rehypePlugins`, and `remarkRehype` options on the MDX integration are also deprecated for the same reason. To anticipate their removal, move them onto `unified({...})` (or your preferred plugin processor) :

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import remarkToc from 'remark-toc';
  import rehypeSlug from 'rehype-slug';
  + import { unified } from '@astrojs/markdown-remark';

  export default defineConfig({
    markdown: {
  +    processor: unified({
  +      remarkPlugins: [remarkToc],
  +      rehypePlugins: [rehypeSlug],
  +      remarkRehype: true,
  +      gfm: true,
  +      smartypants: true,
  +    }),
  -    remarkPlugins: [remarkToc],
  -    rehypePlugins: [rehypeSlug],
  -    remarkRehype: true,
  -    gfm: true,
  -    smartypants: true,
    },
  });
  ```

  For more information on enabling and using this feature in your project, see our [Markdown guide](https://docs.astro.build/en/guides/markdown-content/). To give feedback on this new Rust processor, see the [Native Markdown / MDX parsing and processing RFC](withastro/roadmap#1364).

##### Minor Changes

- [#16848](withastro/astro#16848) [`f732f3c`](withastro/astro@f732f3c) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds support for using [`@astrojs/markdown-satteri`](https://www.npmjs.com/package/@astrojs/markdown-satteri) to parse `.mdx` files.

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [mdx()],
  });
  ```

  Note that the [`recmaPlugins` option](https://docs.astro.build/en/guides/integrations-guide/mdx/#recmaplugins) is not supported when using Sätteri as your MDX processor. If you would like to use Sätteri for Markdown files, but still use Unified for MDX, you can pass a different Markdown processor to the MDX integration:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import mdx from '@astrojs/mdx';
  import { satteri } from '@astrojs/markdown-satteri';
  import { unified } from '@astrojs/markdown-remark';
  import myPlugin from './my-recma-plugin.js';

  export default defineConfig({
    markdown: {
      processor: satteri({
        features: { directive: true },
      }),
    },
    integrations: [
      mdx({
        recmaPlugins: [myPlugin],
        processor: unified(),
      }),
    ],
  });
  ```
