Airflow 3 introduced a game-changing feature: Dag versioning. Gone are the days of “latest only” Dags and confusing, inconsistent UI views when pipelines change mid-flight. This talk covers: Visualizing Dag changes over time in the UI How Dags code is versioned and can be grabbed from external sources Executing a whole Dag run against the same code version Dynamic Dags? Where do they fit in?! You’ll see real-world scenarios, UI demos, and learn how these advancements will help avoid “Airflow amnesia”.

This session presents a comprehensive guide to building applications that integrate with Apache Airflow’s database migration system. We’ll explore how to harness Airflow’s robust Alembic-based migration toolchain to maintain schema compatibility between Airflow and custom applications, enabling developers to create solutions that evolve alongside the Airflow ecosystem without disruption.
