+### `SessionState`'s `sql_to_statement` method takes `Dialect` rather than a
`str`
+
+The `dialect` parameter of `sql_to_statement` method defined in
`datafusion::execution::session_state::SessionState`
+has changed from `&str` to `&Dialect`.
+`Dialect` is an enum defined in the `datafusion-common`
+crate under the `config` module that provides type safety
+and better validation for SQL dialect selection
