- 6a660f1: Adds low-level custom element support that renderers can use to enable server side rendering. This will be used in renderers such as a Lit renderer.
- b3886c2: Enhanced **Markdown** support! Markdown processing has been moved from `micromark` to `remark` to prepare Astro for user-provided `remark` plugins _in the future_.
This change also introduces a built-in `<Markdown>` component for embedding Markdown and any Astro-supported component format inside of `.astro` files. [Read more about Astro's Markdown support.](https://docs.astro.build/markdown/)
