### Patch Changes
- [#6209](https://github.com/withastro/astro/pull/6209) [`fec583909`](https://github.com/withastro/astro/commit/fec583909ab62829dc0c1600e2387979365f2b94) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Introduce the (experimental) `@astrojs/markdoc` integration. This unlocks Markdoc inside your Content Collections, bringing support for Astro and UI components in your content. This also improves Astro core internals to make Content Collections extensible to more file types in the future.
You can install this integration using the `astro add` command:
```
astro add markdoc
```
[Read the `@astrojs/markdoc` documentation](https://docs.astro.build/en/guides/integrations-guide/markdoc/) for usage instructions, and browse the [new `with-markdoc` starter](https://astro.new/with-markdoc) to try for yourself.
- [#6253](https://github.com/withastro/astro/pull/6253) [`0049fda62`](https://github.com/withastro/astro/commit/0049fda62fa8650a0d250adb00a2c5d82679aeaf) Thanks [@bluwy](https://github.com/bluwy)! - Support rehype plugins that inject namespaced attributes. This introduces a breaking change if you use [custom components for HTML elements](https://docs.astro.build/en/guides/markdown-content/#assigning-custom-components-to-html-elements), where the prop passed to the component will be normal HTML casing, e.g. `class` instead of `className`, and `xlink:href` instead of `xlinkHref`.
- **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.
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:
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`.
- 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.
-`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.
- [#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.

```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
- [#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.

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.

#### 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.

⚠️ BREAKING CHANGE ⚠️
If you are using a rehype plugin that depends on heading IDs injected by Astro, the IDs will no longer be available when your plugin runs by default.
To inject IDs before your plugins run, import and add the `rehypeHeadingIds` plugin to your `rehypePlugins` config:
```diff
// astro.config.mjs
+ import { rehypeHeadingIds } from '@astrojs/markdown-remark';
