The Node.js buildpack supports the Bun package manager in General Availability. For more information, see Building a Node.js application.

The Node.js buildpack supports the Bun package manager in Preview. For more information, see Building a Node.js application.

Cloud Run source deployment supports Ubuntu 24 LTS base images in General Availability. This builder is available under gcr.io/buildpacks/builder:google-24. For more information, see Builders.

Support for osonly24 runtime is in General Availability. The OS only runtime lets you deploy binaries such as Dart and Go. For more information, see Configure the OS only runtime.

The Python buildpack supports default entrypoint detection for the Agent Development Kit (ADK) framework in General Availability. For more information, see Build a Python application.

Cloud Run and Cloud Run functions source deployments support the pyproject.toml file for managing dependencies. This feature is in General Availability for all supported Python versions. For more information, see Deploy Python applications with a pyproject.toml file.

The Python buildpack supports default entrypoint detection for the Agent Development Kit (ADK) framework (Preview). For more information, see Build a Python application.

Feature

Cloud Run and Cloud Run functions source deployments support pyproject.toml file for managing dependencies. This feature is in General Availability for Python version 3.13 and later, and is in Preview for Python version 3.12 and earlier. For more information, see Deploy Python applications with a pyproject.toml file.

Support for osonly24 runtime is in Preview. The OS only runtime lets you deploy Go applications from source, and binaries such as Dart and Go. For more information, see Configure the OS only runtime.

Cloud Run and Cloud Run functions source deployments support pyproject.toml file for managing dependencies. If you use a pyproject.toml file, source deployments use one of the following to find and install dependencies:

• pip
• uv
• poetry

For more information, see Deploy Python applications with a pyproject.toml file (Preview).

Ubuntu 24 builder with the google-24 stack is available for Google Cloud's Buildpacks. For more information, see Builders and Use a specific builder.

The Python buildpack supports Cloud Run source deployments for modern web frameworks such as FastAPI, Gradio, and Streamlit.

For Python version 3.13 and later, the Python buildpack sets the default entrypoint for Cloud Run source deployments based on the web server or framework configuration in your requirements.txt file. For more information, see Build a Python application.

The runtime support schedule for some PHP runtimes has been extended to match PHP's public support schedule.

Starting in Go version 1.22 and later, you can no longer use GOPATH for installing dependencies. To manage dependencies, you use a go.mod file. For more information about Go versions, and managing dependencies for vendor directories, see GOPATH and Modules in Go documentation.

The support policy and schedule for Google Cloud's buildpacks is now available at https://cloud.google.com/docs/buildpacks/support-policy.

The Python buildpack now uses gunicorn --bind :8080 main:app as the default entrypoint for all web applications. If you currently use a Procfile, it will continue to work but you are no longer required to configure a Procfile for your projects. Learn more about Python application entrypoints.

The default generic builder now uses the Ubuntu 22 LTS base image. When you specify the latest location, the builds now uses the google-22 builder by default. For example, you can specify either of the following to use google-22:

• gcr.io/buildpacks/builder:latest
• gcr.io/buildpacks/builder:google-22

If you need to pin your build to the previous Ubuntu 18 builder, see the instructions about how to configure the builder version, including:

• pack commands for local builds.
• gcloud commands for remote builds.
• How to configure the project.toml for Cloud Run.

The Java runtime now supports using Maven wrappers for managing your project's dependency on Maven.

You can use the Pnpm package manager to configure dependencies for Node.js runtimes. Learn how to configure your application.

Starting June 5, 2023, the default generic builder will begin using the Ubuntu 22 LTS base image. This means that builds using gcr.io/buildpacks/builder:latest will get the google-22 builder which addresses multiple security issues. You can read more about the google-22 builder in our announcement on GitHub.

You can preview the new builder by adding --builder=gcr.io/buildpacks/builder:google-22 to the gcloud builds submit --pack command when you build your application with a specific builder.
