   Before this version, all groups were read, but conflicting variable names in-between groups would shadow data.  Now, similarly to xarray ``open_dataset``, ``open_ncml`` accepts an optional ``group`` argument to specify which group should be read. When ``group`` is not specified, it defaults to the root group. Additionally ``group`` can be set to ``'*'`` so that every group is read and the hierarchy is flattened.   In the event of conflicting variable/dimension names across groups, the conflicting name will be modified by appending ``'__n'`` where n is incremented.
 - Enums are no longer transformed into CF flag_values and flag_meanings attributes, instead they are stored in the ``encoding["dtype"].metadata`` of their respective variable. This is aligned with what is done on xarray v2024.01.0
 
+- [fix] scalar attributes that are not strings are no longer wrapped in a tuple of length 1.
