 New Features
 ------------

+  single-level and nested layouts) added to replace functionality of removed ``metadata`` container.

   commits / branches without needing to open the diff base in a checkout.

 Removed
 -------
 
+* ``metadata`` container for ``str`` typed data has been completly removed. It is replaced by a highly

   is no longer supported.
