Regression in 1.3.14

While upgrading sqlalchemy from 1.3.13 to 1.3.14 I get this error:

...

                # raising FlushError with "chaining" to remain compatible
                # with code that catches StatementError, IntegrityError,

                    "flush is occurring prematurely"
                )

For me, it looks to be a regression, what do you think?
