What is Buildkite?

Buildkite drops long-lived GitHub credentials from self-hosted agents

Buildkite's recent changelog fills infrastructure gaps teams used to cover with plugins or custom images. Self-hosted agents can now check out private GitHub repositories with temporary, read-only GitHub App tokens instead of SSH keys or personal access tokens. OpenTelemetry trace context now passes from parent builds to triggered builds without a Support request. October also brought Buildkite Cache GA, cluster-level OpenTelemetry, queue-filtered webhooks and Test Engine workflows in Terraform.

What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

Buildkite drops long-lived GitHub credentials from self-hosted agents

◆ Current state

Buildkite's recent changelog fills infrastructure gaps teams used to cover with plugins or custom images. Self-hosted agents can now check out private GitHub repositories with temporary, read-only GitHub App tokens instead of SSH keys or personal access tokens. OpenTelemetry trace context now passes from parent builds to triggered builds without a Support request. October also brought Buildkite Cache GA, cluster-level OpenTelemetry, queue-filtered webhooks and Test Engine workflows in Terraform.

◆ Where it's heading

The theme is removing per-agent setup: credentials, caching and telemetry all move from something each machine carries to something Buildkite supplies. Observability work has stepped from cluster-level config to cross-pipeline traces within two weeks.

◆ Prediction

Expect more of the remaining on-request options, such as HTTP traceparent acceptance, to become self-serve, following the trace propagation change.

5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.
