v3.120.1 (2026-03-17)

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 [email protected].
