[!TIP]
🎉 ✨ Streaming job dispatch (Public Preview): This release 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/v3You may alternatively use the environment variable
BUILDKITE_AGENT_ENDPOINTor edit yourbuildkite-agent.cfgto containendpoint=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.
[!NOTE]
The minimum version of Go used to build the agent is now Go 1.25.
