-- Bug in ``.to_latex()`` where ``bold_rows`` was disregarded and always assumed to be False. This affected also the default behaviour with ``bold_rows`` omitted. (:issue:`16707`)
+- Bug in ``.to_latex()`` where ``bold_rows`` was wrongly specified to be True by default, whereas in reality row labels remained non-bold whatever parameter provided. (:issue:`16707`)
