Flask-SQLAlchemy 2.5.1 uses _include_sqlalchemy() which iterates over sqlalchemy.__all__, but SQLAlchemy 2.0 removed __all__. This causes an AttributeError crash on startup: AttributeError: module 'sqlalchemy' has no attribute '__all__' The previous pin (==2.0.30) was incompatible with Flask-SQLAlchemy 2.5.1. Pin to <2.0 until Flask-SQLAlchemy is upgraded to 3.x.
