Cloud Composer version list

This page describes the released versions of Cloud Composer images.

For a list of changes in Cloud Composer releases, see Release notes.

About Cloud Composer images

Cloud Composer builds Docker images that bundle Airflow releases with other common binaries and Python libraries. These Docker images are versioned with each Cloud Composer service release.

When you create an environment, you specify an image version to use. Once an environment is created, it keeps using the specified image version until you upgrade it to a later version.

Latest version

When you create a new environment or upgrade an existing one, only the latest versions of Cloud Composer images are available as choices.

Default version

Each Cloud Composer version supports more than one Airflow version. If you do not specify an image version when you create an environment, the default version is used.

Versions with an extended upgrade timeline

In general, you can upgrade your environment from any version of Cloud Composer only to the latest version, three previous versions of Cloud Composer, and to versions with an extended upgrade timeline.

You can upgrade your environment to a version with an extended upgrade timeline until this version reaches its security notifications end date.

Version support dates

Each Cloud Composer image has a release date and two support dates associated with it. The support dates are based on Cloud Composer version deprecation and support periods.
