Breaking change to GitHub Copilot service endpoints

Starting tomorrow Tuesday, September 26, 2023 we are updating the service endpoints for organizations with GitHub Copilot Chat beta enabled. If your organization uses a firewall to restrict network traffic, we recommend updating your allowlist to include *.githubcopilot.com if you haven’t done so already. This endpoint is required to deliver Copilot Chat messages.

If you are not ready to upgrade to this new endpoint, you can pin your GitHub Copilot Chat version to 0.7.1 or earlier.

If your organization doesn’t use a firewall to restrict network traffic, then no change is necessary. For a complete list of GitHub Copilot service endpoints, see our docs.

GitHub Actions: Transitioning from Node 16 to Node 20

Node 16 has reached its end of life, prompting us to initiate its deprecation process for GitHub Actions. Our plan is to transition all actions to run on Node 20 by Spring 2024. We will actively monitor the migration's progress and gather community feedback before finalizing the transition date. Starting October 23rd, workflows containing actions running on Node 16 will display a warning to alert users about the upcoming migration.

What you need to do

For Actions maintainers

Modify your actions to run on Node 20 instead of Node 16. For guidance, refer to the Actions configuration settings.

For Actions users

Ensure your workflows use the latest versions of actions that are running on Node 20. For more information, see Using Versions for Actions.

For self-hosted runner administrators:

Update your self-hosted runners to runner version v2.308.0 or later to ensure compatibility with Node 20 actions.

Passkeys are Generally Available

Passkeys are a replacement for passwords when signing in, providing higher security, ease-of-use, and loss-protection. They are now generally available on GitHub.com for all users. By using a passkey you no longer need to enter a password, or even your username, when you sign in – nor do you need to perform 2FA, if you have 2FA enabled on your account. This is because passkeys validate your identity, as well as possession of a device, so they count as two authentication factors in one. Once enrolled, you can register a brand new passkey and upgrade many security keys to passkeys.

Screenshot of the security key upgrade prompt, asking the user if they'd like to upgrade a security key called 'fingerprint' to a passkey.

To learn more, check out our documentation "About passkeys", as well as this previous blog post from the passkeys beta announcement. If you have any feedback, please drop us a note in our public discussion – we're excited for this advance in account security, and would love to understand how we can make it better for you.
