@@ -42,6 +42,7 @@ sections up to the index to be used with the `get_section` Tera function
- Add `transparent` sections, for when you want to separate content by sections but want to group them at a higher level (think a `posts` folder with years
that want to use pagination on the index).
- Add `page_template` to section front-matter for when you want to specify the template to use for every page under it
- Improves to `zola serve`: now handles files/directories renaming
