+
+Remove support for `Astro.__renderMarkdown` which is used by `@astrojs/markdown-component`. 
+
+The `<Markdown />` component was deprecated in Astro v1 and is completely removed in v3. This integration must now be removed from your project.
+
+As an alternative, you can use community packages that provide a similar component like https://github.com/natemoo-re/astro-remote instead.
