+* Normalization now supports numeric types with precision greater than 32 bits
+* Normalization now supports union data types
+* Support longform text inputs in the UI for cases where you need to preserve formatting on connector inputs like .pem keys
+* Expose the latest available connector versions in the API
+* Airflow: published a new [tutorial](https://docs.airbyte.io/tutorials/using-the-airflow-airbyte-operator) for how to use the Airbyte operator. Thanks [@Marcos Marx](https://github.com/marcosmarxm) for writing the tutorial! 
+* Connector Contributions: All connectors now describe how to contribute to them without having to touch Airbyte’s monorepo build system -- just work on the connector in your favorite dev setup!

+* Integration with Airflow is here. Thanks to @Marcos Marx, you can now run Airbyte jobs from Airflow directly. A tutorial is on the way and should be coming this week!
