GitHub Actions: macOS 15 and Windows 2025 images are now generally available

macOS 15 and Windows 2025 images are now generally available for all GitHub-hosted runners. You can use these images in your workflows on GitHub-hosted standard or larger runners.

Get started today

To use macOS 15 directly, update runs-on: in your workflow file to macos-15, macos-15-xlarge, or macos-15-large.

jobs:
  build:
    runs-on: macos-15
    steps:
      - uses: actions/checkout@v4
      - name: Build
        run: swift build
      - name: Run tests
        run: swift test

To use Windows 2025, you can target the image directly on standard runners using runs-on: windows-2025. For larger runners, create a runner and select Windows Server 2025 in the Images UI console.

The latest tag will migrate to these images later in the year.

Need support?

Keep in mind that the new runner images have different tools and tool versions than previous versions. To view the full list of software or report issues with your workflows when using the images, visit the runner-images repository.

Copilot Chat now supports pasting GitHub URLs as explicit references

Issues, discussions, and pull requests – these are all important pieces of context when building in GitHub. Now, you can reference these within Copilot Chat. Simply paste a link into the chat and Copilot will do the rest!

How it helps you

  • 📂 Multi-repository support: want to compare a pull request from one project with a discussion from another? No problem!
  • 🏷️ Intuitive navigation: maybe you pasted a link, got up to make a coffee, and forgot what you were doing. With chips in the chat context, you don’t need to worry – it will always be clear what you’ve added.
  • ⌨️ Context-building at your fingertips: let Copilot support you and integrate your work by focusing on the specific problems you want to address.

We like to think that GitHub files and Copilot are both great, and they’re even better when they come together. The power of Copilot and the fountain of knowledge in your repositories will collectively help you do amazing things. We know it.

GitHub Actions hosted runner fleet now includes 96 vCPU larger runner

GitHub Actions 96 vCPU larger runners are now generally available. Customers in need of bigger, more powerful machines to run their workloads can use this runner to reduce runtime on their longer GitHub Actions builds.

This runner is an x64 machine and you can use any of our existing GitHub-owned Linux and Windows images on these runners. Our entire advanced feature set works with the new runner: static IPs, network configurations, autoscaling, and runner groups.

What are the machine specs?

  • vCPU: 96
  • RAM: 384 GB
  • SSD: 2040 GiB

Get started today

To get started, create a new, larger runner and choose the 96-core option in the Size console in the UI. Learn more about how to set up larger runners in our documentation. For pricing information on these larger runners see the billing for GitHub Actions page.
