+.. change::
+    :tags: change, asyncio
+
+    The ``async_fallback`` dialect argument is now deprecated, and will be
+    removed in SQLAlchemy 2.1.   This flag has not been used for SQLAlchemy's
+    test suite for some time.   asyncio dialects can still run in a synchronous
+    style by running code within a greenlet using :func:`_util.greenlet_spawn`.
