 - The ``table.insert_all()`` and ``table.upsert_all()`` methods can now accept an iterator of lists or tuples as an alternative to dictionaries. The first item should be a list/tuple of column names. See :ref:`python_api_insert_lists` for details. (:issue:`672`)
-- **Breaking change:** The default floating point column type has been changed from ``FLOAT`` to ``REAL``, which is the correct SQLite type for floating point values. This affects auto-detected columns when inserting data. You can still explicitly specify ``"FLOAT"`` or ``"float"`` as a column type for backwards compatibility. (:issue:`645`)
