+### Author Metadata
+
+From `Minima-3.0` onwards, `site.author` is expected to be a mapping of attributes instead of a simple scalar value:

+```yaml
+author:
+  name: John Smith
+  email: "[email protected]"

+Minima 2.x    | Minima 3.0
+------------- | -------------------
+`site.author` | `site.author.name`
+`site.email`  | `site.author.email`
