Changes and Migration

SQLAlchemy changelogs and migration guides are now integrated within the main documentation.

Current Migration Guide

For SQLAlchemy 2.0, there are two separate documents; the “Major Migration Guide” details how to update a SQLAlchemy 1.4 application to be compatible under SQLAlchemy 2.0. The “What’s New?” document details major new features, capabilities and behaviors in SQLAlchemy 2.0.
