### Major Changes

- [#5687](https://github.com/withastro/astro/pull/5687) [`e2019be6f`](https://github.com/withastro/astro/commit/e2019be6ffa46fa33d92cfd346f9ecbe51bb7144) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Give remark and rehype plugins access to user frontmatter via frontmatter injection. This means `data.astro.frontmatter` is now the _complete_ Markdown or MDX document's frontmatter, rather than an empty object.

  This allows plugin authors to modify existing frontmatter, or compute new properties based on other properties. For example, say you want to compute a full image URL based on an `imageSrc` slug in your document frontmatter:

  ```ts
  export function remarkInjectSocialImagePlugin() {
    return function (tree, file) {
      const { frontmatter } = file.data.astro;
      frontmatter.socialImageSrc = new URL(frontmatter.imageSrc, 'https://my-blog.com/').pathname;
    };
  }
  ```

  When using Content Collections, you can access this modified frontmatter using the `remarkPluginFrontmatter` property returned when rendering an entry.

  **Migration instructions**

  Plugin authors should now **check for user frontmatter when applying defaults.**

  For example, say a remark plugin wants to apply a default `title` if none is present. Add a conditional to check if the property is present, and update if none exists:

  ```diff
  export function remarkInjectTitlePlugin() {
    return function (tree, file) {
      const { frontmatter } = file.data.astro;
  +    if (!frontmatter.title) {
        frontmatter.title = 'Default title';
  +    }
    }
  }
  ```

  This differs from previous behavior, where a Markdown file's frontmatter would _always_ override frontmatter injected via remark or reype.

  - **Markdown**

    - **Replace the `extendDefaultPlugins` option** with a `gfm` boolean and a `smartypants` boolean. These are enabled by default, and can be disabled to remove GitHub-Flavored Markdown and SmartyPants.

    - Ensure GitHub-Flavored Markdown and SmartyPants are applied whether or not custom `remarkPlugins` or `rehypePlugins` are configured. If you want to apply custom plugins _and_ remove Astro's default plugins, manually set `gfm: false` and `smartypants: false` in your config.

  - **Migrate `extendDefaultPlugins` to `gfm` and `smartypants`**

    You may have disabled Astro's built-in plugins (GitHub-Flavored Markdown and Smartypants) with the `extendDefaultPlugins` option. This has now been split into 2 flags to disable each plugin individually:

    - `markdown.gfm` to disable GitHub-Flavored Markdown
    - `markdown.smartypants` to disable SmartyPants

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

    export default defineConfig({
      markdown: {
    -   extendDefaultPlugins: false,
    +   smartypants: false,
    +   gfm: false,
      }
    });
    ```

    Additionally, applying remark and rehype plugins **no longer disables** `gfm` and `smartypants`. You will need to opt-out manually by setting `gfm` and `smartypants` to `false`.

  - **MDX**

    - Support _all_ Markdown configuration options (except `drafts`) from your MDX integration config. This includes `syntaxHighlighting` and `shikiConfig` options to further customize the MDX renderer.

    - Simplify `extendPlugins` to an `extendMarkdownConfig` option. MDX options will default to their equivalent in your Markdown config. By setting `extendMarkdownConfig` to false, you can "eject" to set your own syntax highlighting, plugins, and more.

  - **Migrate MDX's `extendPlugins` to `extendMarkdownConfig`**

    You may have used the `extendPlugins` option to manage plugin defaults in MDX. This has been replaced by 3 flags:

    - `extendMarkdownConfig` (`true` by default) to toggle Markdown config inheritance. This replaces the `extendPlugins: 'markdown'` option.
    - `gfm` (`true` by default) and `smartypants` (`true` by default) to toggle GitHub-Flavored Markdown and SmartyPants in MDX. This replaces the `extendPlugins: 'defaults'` option.

## 2.0.0-beta.1



See changes in 2.0.0-beta.1

### Minor Changes

- [#5769](https://github.com/withastro/astro/pull/5769) [`93e633922`](https://github.com/withastro/astro/commit/93e633922c2e449df3bb2357b3683af1d3c0e07b) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Introduce a `smartypants` flag to opt-out of Astro's default SmartyPants plugin.

  ```js
  {
    markdown: {
      smartypants: false,
    }
  }
  ```

  #### Migration

  You may have disabled Astro's built-in plugins (GitHub-Flavored Markdown and Smartypants) with the `extendDefaultPlugins` option. This has now been split into 2 flags to disable each plugin individually:

  - `markdown.gfm` to disable GitHub-Flavored Markdown
  - `markdown.smartypants` to disable SmartyPants

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

  export default defineConfig({
    markdown: {
  -   extendDefaultPlugins: false,
  +   smartypants: false,
  +   gfm: false,
    }
  });
  ```




## 2.0.0-beta.0



See changes in 2.0.0-beta.0

### Major Changes

- [#5687](https://github.com/withastro/astro/pull/5687) [`e2019be6f`](https://github.com/withastro/astro/commit/e2019be6ffa46fa33d92cfd346f9ecbe51bb7144) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Give remark and rehype plugins access to user frontmatter via frontmatter injection. This means `data.astro.frontmatter` is now the _complete_ Markdown or MDX document's frontmatter, rather than an empty object.

  This allows plugin authors to modify existing frontmatter, or compute new properties based on other properties. For example, say you want to compute a full image URL based on an `imageSrc` slug in your document frontmatter:

  ```ts
  export function remarkInjectSocialImagePlugin() {
    return function (tree, file) {
      const { frontmatter } = file.data.astro;
      frontmatter.socialImageSrc = new URL(frontmatter.imageSrc, 'https://my-blog.com/').pathname;
    };
  }
  ```

  #### Content Collections - new `remarkPluginFrontmatter` property

  We have changed _inject_ frontmatter to _modify_ frontmatter in our docs to improve discoverability. This is based on support forum feedback, where "injection" is rarely the term used.

  To reflect this, the `injectedFrontmatter` property has been renamed to `remarkPluginFrontmatter`. This should clarify this plugin is still separate from the `data` export Content Collections expose today.

  #### Migration instructions

  Plugin authors should now **check for user frontmatter when applying defaults.**

  For example, say a remark plugin wants to apply a default `title` if none is present. Add a conditional to check if the property is present, and update if none exists:

  ```diff
  export function remarkInjectTitlePlugin() {
    return function (tree, file) {
      const { frontmatter } = file.data.astro;
  +    if (!frontmatter.title) {
        frontmatter.title = 'Default title';
  +    }
    }
  }
  ```

  This differs from previous behavior, where a Markdown file's frontmatter would _always_ override frontmatter injected via remark or reype.

- [#5684](https://github.com/withastro/astro/pull/5684) [`a9c292026`](https://github.com/withastro/astro/commit/a9c2920264e36cc5dc05f4adc1912187979edb0d) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Refine Markdown and MDX configuration options for ease-of-use.

  #### Markdown

  - **Remove `remark-smartypants`** from Astro's default Markdown plugins.
  - **Replace the `extendDefaultPlugins` option** with a simplified `gfm` boolean. This is enabled by default, and can be disabled to remove GitHub-Flavored Markdown.
  - Ensure GitHub-Flavored Markdown is applied whether or not custom `remarkPlugins` or `rehypePlugins` are configured. If you want to apply custom plugins _and_ remove GFM, manually set `gfm: false` in your config.

  #### MDX

  - Support _all_ Markdown configuration options (except `drafts`) from your MDX integration config. This includes `syntaxHighlighting` and `shikiConfig` options to further customize the MDX renderer.
  - Simplify `extendDefaults` to an `extendMarkdownConfig` option. MDX options will default to their equivalent in your Markdown config. By setting `extendMarkdownConfig` to false, you can "eject" to set your own syntax highlighting, plugins, and more.

  #### Migration

  To preserve your existing Markdown and MDX setup, you may need some configuration changes:

  ##### Smartypants manual installation

  [Smartypants](https://github.com/silvenon/remark-smartypants) has been removed from Astro's default setup. If you rely on this plugin, [install `remark-smartypants`](https://github.com/silvenon/remark-smartypants#installing) and apply to your `astro.config.*`:

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  + import smartypants from 'remark-smartypants';

  export default defineConfig({
    markdown: {
  +   remarkPlugins: [smartypants],
    }
  });
  ```

  ##### Migrate `extendDefaultPlugins` to `gfm`

  You may have disabled Astro's built-in plugins (GitHub-Flavored Markdown and Smartypants) with the `extendDefaultPlugins` option. Since Smartypants has been removed, this has been renamed to `gfm`.

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

  export default defineConfig({
    markdown: {
  -   extendDefaultPlugins: false,
  +   gfm: false,
    }
  });
  ```

  Additionally, applying remark and rehype plugins **no longer disables** `gfm`. You will need to opt-out manually by setting `gfm` to `false`.

  ##### Migrate MDX's `extendPlugins` to `extendMarkdownConfig`

  You may have used the `extendPlugins` option to manage plugin defaults in MDX. This has been replaced by 2 flags:

  - `extendMarkdownConfig` (`true` by default) to toggle Markdown config inheritance. This replaces the `extendPlugins: 'markdown'` option.
  - `gfm` (`true` by default) to toggle GitHub-Flavored Markdown in MDX. This replaces the `extendPlugins: 'defaults'` option.




## 1.2.0

### Minor Changes

- [#5654](https://github.com/withastro/astro/pull/5654) [`2c65b433b`](https://github.com/withastro/astro/commit/2c65b433bf840a1bb93b0a1947df5949e33512ff) Thanks [@delucis](https://github.com/delucis)! - Refactor and export `rehypeHeadingIds` plugin

  The `rehypeHeadingIds` plugin injects IDs for all headings in a Markdown document and can now also handle MDX inputs if needed. You can import and use this plugin if you need heading IDs to be injected _before_ other rehype plugins run.

### Minor Changes

- d396943: Add support for [`remark`](https://github.com/remarkjs/remark#readme) and [`rehype`](https://github.com/rehypejs/rehype#readme) plugins for both `.md` pages and `.astro` pages using the [``](/docs/guides/markdown-content.md) component.

  For example, the `astro.config.mjs` could be updated to include the following. [Read the Markdown documentation](/docs/guides/markdown-content.md) for more information.

  > **Note** Enabling custom `remarkPlugins` or `rehypePlugins` removes Astro's built-in support for [GitHub-flavored Markdown](https://github.github.com/gfm/) support, [Footnotes](https://github.com/remarkjs/remark-footnotes) syntax, [Smartypants](https://github.com/silvenon/remark-smartypants). You must explicitly add these plugins to your `astro.config.mjs` file, if desired.

  ```js
  export default {
    markdownOptions: {
      remarkPlugins: ['remark-slug', ['remark-autolink-headings', { behavior: 'prepend' }]],
      rehypePlugins: ['rehype-slug', ['rehype-autolink-headings', { behavior: 'prepend' }]],
    },
  };
  ```
