+## v5 - What's new
+
+Previously, **single artifact downloads** behaved differently depending on how you specified the artifact:
+
+- **By name**: `name: my-artifact` → extracted to `path/` (direct)
+- **By ID**: `artifact-ids: 12345` → extracted to `path/my-artifact/` (nested)
+
+Now both methods are consistent:
+
+- **By name**: `name: my-artifact` → extracted to `path/` (unchanged)
+- **By ID**: `artifact-ids: 12345` → extracted to `path/` (updated - now direct)
+
+Note: This change also applies to patterns that only match a single artifact.
 
 ## v4 - What's new
