* ``sqlite3.enable_shared_cache()``
* ``sqlite3.OptimizedUnicode``
+ If a shared cache must be used, open the database in URI mode using the
+ ``cache=shared`` query parameter.
+
+ The ``sqlite3.OptimizedUnicode`` text factory has been an alias for
+ :class:`str` since Python 3.3. Code that previously set the text factory to
+ ``OptimizedUnicode`` can either use ``str`` explicitly, or rely on the
+ default value which is also ``str``.
