GitHub Actions has recently made changes to the available macOS runner images and the GitHub meta API. Below is a summary of the changes and possible impact to your use of GitHub-hosted macOS runners:

GitHub announced in April 2024 the general availability of macOS 14. As of today, we have completed the migration and all macos-latest workflows now use macOS 14.

In January 2024, GitHub announced the deprecation of macOS 11 and the removal of the runner image by June 2024. The macOS 11 runner image will be removed on 6/28/2024. We recommend updating workflows to use macos-14, macos-13, macos-12, or macos-latest. Reminder emails will be sent to those who have used the macOS 11 runner image in the past 30 days. Jobs using macOS 11 will temporarily fail during scheduled time periods to raise awareness of the upcoming removal. The schedule can be found below:

• June 17 2024, 8:00 AM – 2:00 PM EST
• June 19 2024, 12:00 PM – 6:00 PM EST
• June 24 2024, 3:00 AM – 9:00 PM EST
• June 26 2024, 8:00 AM – 2:00 PM EST

Developers and teams have requested that Actions separate macOS runner IP ranges from the rest of Actions so they can allow list them. As of today, developers can isolate macOS runners from the rest of Actions in the GitHub API by using the actions_macos object. The IP addresses may change periodically due to new hardware being brought online or maintenance being performed. To ensure that developers have the most up-to-date information, the IP addresses are refreshed every Monday at 12:30 PM EST.

You can always get up-to-date information on our tools by reading about the software in the runner images repository. For more information on how to use the GitHub API, please see our docs. If you run into any problems or need help, please contact GitHub Support.

Following on from our announcement of the end of Node16 support we have a new timeline for Node16 end of life in Actions.

On June 30th 2024, we will change the default from Node16 to Node20.
To opt out of this and continue using Node16 while it is still available in the runner, you can choose to set ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true

We will then continue to monitor Node16 usage and will communicate a timeline for the removal of Node16 at the start of October, based on the volume of continued use. This means that customers who use the environment variable to continue to use Node16 now have until October to complete their migrations.

GitHub Enterprise Server 3.13 gives customers more fine-grained control over deployment requirements, and enhanced security controls. Here are a few highlights:

• We are introducing a new feature for repositories called custom properties, a major enhancement to how repositories are managed and classified across GitHub organizations. Properties offer a flexible way to add meaningful metadata to your repositories that simplifies repository classification, enhances discoverability, and seamlessly integrates with rulesets. Check out the demo! For more information, see custom properties for repositories.

• Elasticsearch will be upgraded from version 5 to version 8, when the appliance is upgraded to 3.13. Elasticsearch powers all search experiences in GHES including code search and audit logs. Upgrading ES5 to ES8 allows the platform to take advantage of better performance and improved security posture in ES8. For more information regarding what to expect during ES8 upgrade, see Preparing for Elasticsearch upgrade in GHES 3.13. Downnload the 3.13 RC candidate now, upgrade your staging environment and share your feedback with us!

• Enterprise and organization audit log events now include the applicable SAML and SCIM identity data associated with the user. For more information, see Reviewing the audit log for your organization.

• Developers who use devcontainer.json files to define their development containers will now be able to use Dependabot version updates to keep their dependencies in the container up-to-date. Once configured in dependabot.yml, Dependabot will open PRs on a specified schedule to update the listed dependencies to latest.

• Pull Requests rebases are now faster! Under the hood, rebase commits now use the merge-ort. Rebases that timed out for large repositories before are now a lot more likely to be successful.

• Using Project Status Updates, you can now provide high level details on the status, timing, and progress of your project, directly from the project! This makes it easy to know and share with others how your work is progressing, any risks, and a history of when and why something changed, all in the same place where you’re tracking your work.

Release Candidates are a way for you to try the latest features early, and they help us gather feedback to
ensure the release works in your environment. They should be tested on non-production environments.
