### Categories can now be replaced
2+
3+
Previously the API POST /files/{id}/metadata/categories could only add new categories to the categories list. Now with the query parameter ?replace=true the list of categories will be replaced.

Updates the categories for an existing file where ``ID`` is the database id of the file to update or ``PERSISTENT_ID`` is the persistent id (DOI or Handle) of the file. Requires a ``jsonString`` expressing the category names.

The list of "categories" will be added to the existing list unless the optional ``replace=true`` query parameter is included. The inclusion of this parameter will cause the pre-existing categories to be deleted and the new "categories" to be added. Sending an empty list will remove all of the pre-existing categories.

Although updating categories can also be done with the previous endpoint, this has been created to be more practical when it is only necessary to update categories and not other metadata fields.
