The Python buildpack supports Cloud Run source deployments for modern web frameworks such asFastAPI,Gradio, andStreamlit.
For Python version 3.13 and later, the Python buildpack sets the default entrypoint forCloud Run source deploymentsbased on the web server or framework configuration in yourrequirements.txtfile. For more information, seeBuild a Python application.
Starting in Go version 1.22 and later, you can no longer useGOPATHfor installing dependencies. To manage dependencies, you use ago.modfile. For more information about Go versions, and managing dependencies for vendor directories, seeGOPATH and Modulesin Go documentation.
The Python buildpack now usesgunicorn --bind :8080 main:appas the default entrypoint for all web applications. If you currently use aProcfile, it will continue to work but you are no longer required to configure aProcfilefor your projects. Learn more aboutPython application entrypoints.

Starting June 5, 2023, the default generic builder will begin using the Ubuntu 22 LTS base image. This means that builds usinggcr.io/buildpacks/builder:latestwill get thegoogle-22builder which addresses multiple security issues. You can read more about thegoogle-22builder in ourannouncement on GitHub.
You can preview the new builder by adding--builder=gcr.io/buildpacks/builder:google-22to thegcloud builds submit --packcommand when you build your application with aspecific builder.
