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 Terragrunt?

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

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

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

◆ Current state

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

◆ Where it's heading

The graduation model has repeated at a larger scale: six experiments in v1.1, eleven in v1.2. The candidates ran as stabilization, with fixes concentrated in the CAS, the catalog and the Provider Cache Server. Each breaking change also ships with an escape hatch, base64gzip_compat() or enable_bucket_root_access, which shows how seriously the project treats its 1.0 guarantees.

◆ Prediction

v1.2.0 final is the next release, since rc3 says only regression or urgent fixes will land first. It has not appeared in this feed in the 18 days since rc3.
