Creating a new application from scratch installing TurboGears 2.4.3 tg.devtools returns a version conflict between SQLAlchemy (automatically installed version is 1.4.11 as per 2021-04-27) and zope-sqlalchemy (installed as version 1.4). Solved manually by reinstalling SQLAlchemy 1.3.25, but should possibly work out-of-the-box for new users.
