+
+You can now present a changelog as a blog, with dated entries rendered as cards in a grid or list. Set `layout: blog` and `blog-layout` in the changelog overview frontmatter; the `blog:` navigation key is an alias for `changelog:`.

 The per-changelog override takes priority over the site-wide `layout.changelog-layout` setting.
 
+## Blog layout
+
+The `blog` layout renders one card for each dated entry file. Unlike the `timeline` layout, which creates a card for each top-level `##` heading, the `blog` layout creates one card per file.
+
+Set `layout: blog` in the changelog folder's `overview.mdx` frontmatter. Use `blog-layout: grid` for the default card grid or `blog-layout: list` for full-width rows with the image beside the text. List rows stack on narrow viewports. Values other than `list` use the grid layout.

+Configure blog metadata in the overview and entry frontmatter:
+
+- An optional `authors` map in the overview frontmatter registers authors by ID. Each author requires `name` and can include `role`, `avatar`, and `url`.
+- `title` sets the post title and falls back to the entry title.
+- `slug` overrides the date-derived URL. The value is a full slug relative to the site base (or the product or version base, when one applies), so a post under a blog at `/blog` needs `slug: blog/my-post`.
+- `tags` adds tags to the post.
+- The excerpt uses `description`, then `subtitle`, then `excerpt`, and falls back to the first approximately 200 characters of the body.
+- `thumbnail` or `image` sets the card and hero image.
+- `author` or `authors` can name keys in the overview's `authors` registry or provide inline author objects with `name`, `role`, `avatar`, and `url`.
+- `draft: true` or `hidden: true` excludes the post from the listing.
+
+Entry files, dates, and reserved overview filenames follow the standard changelog rules. Search, tag filtering, entry pages, and RSS, Atom, and JSON feeds work the same way as they do for a changelog.

 ## Linking and sharing
 
 Each changelog entry has a unique URL you can direct users to. For example, `https://elevenlabs.io/docs/changelog/2025/3/31`
