Python 2.7 has reached end of support and will be deprecated on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7 applications, even if your organization previously used an organization policy to re-enable deployments of legacy runtimes. Your existing Python 2.7 applications will continue to run and receive traffic after their deprecation date. We recommend that you migrate to the latest supported version of Python.

The standalone App Engine SDK was deprecated as of July 30, 2019, and it is now shut down. The following table lists features and their recommended alternatives:
