Tip

In order to make Git Mirrors more reliable, checkouts using a mirror can now be dissociated from the mirror. This approach still avoids fetching objects from the remote if they are present the mirror, but stores a copy of the objects in the checkout, preventing the checkout from becoming corrupted through entirely normal operation of the mirror.
To opt into this behaviour set the flag --git-mirror-checkout-mode=dissociate or agent environment variable BUILDKITE_GIT_MIRROR_CHECKOUT_MODE=dissociate.

Added

• Add GCP KMS Signing #3660 (@tomowatt)
• Support for dissociated clones of git mirrors #3775, #3788 (@DrJosh9000)
• Add --subject-claim flag to oidc request-token #3784 (@zero51)

Changed

• Job logger trace correlation #3782 (@aapzu)

Full Changelog

Tip

🎉 ✨ Streaming job dispatch (Public Preview): Version 3.120.0 adds opt-in support for a new streaming connection between agents and Buildkite, significantly reducing job acceptance latency for self-hosted agents. To try it, start your agent with --endpoint https://agent-edge.buildkite.com/v3, for example:

buildkite-agent start --endpoint https://agent-edge.buildkite.com/v3

You may alternatively use the environment variable BUILDKITE_AGENT_ENDPOINT or edit your buildkite-agent.cfg to contain endpoint=https://agent-edge.buildkite.com/v3.

This capability is in public preview and will become the default in a future release. If you have any feedback or run into issues, please reach out to support@buildkite.com.
