+CLI API
+~~~~~~~
+
+* The ``pyhf xlm2json`` CLI API now has a ``-v/--mount`` option to support reading
+  XML configurations with absolute paths.
+  (PR :pr:`1909`)
+  Similar to Docker volume mounts, the options allows a user to pass two fields
+  separated by a colon (``:``).
+  The first field is a local path and the second field is the absolute path specified
+  in the XML configuration to be substituted.
+  Without the ``-v/--mount`` option a user would have to manually edit the absolute
+  path in each XML file it appeared in!
