+
+Removes the requirement for non-content files and assets inside content collections to be prefixed with an underscore. For files with extensions like `.astro` or `.css`, you can now remove underscores without seeing a warning in the terminal.
+
+```diff
+src/content/blog/
+post.mdx
+- _styles.css
+- _Component.astro
++ styles.css
++ Component.astro
+```
+
+Continue to use underscores in your content collections to exclude individual content files, such as drafts, from the build output.
