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 Merge?
Merge adds connectors and new models weekly while fixing ERP sync details underneath.
Merge ships weekly across Gateway, Unified and Agent Handler. October brought new Agent Handler connectors (Google Workspace, Ironclad, Zoom Phone, Meta Ads, TikTok for Business, Warp), Gateway support for GPT-6.1 Terra, Gemini 4 Argon and Mistral Large 4, custom prompt classifiers and a management API for security rules. Unified got NetSuite, QuickBooks, SharePoint and Jira sync fixes.

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.
Merge
5.0INFRA · APIS
Merge adds connectors and new models weekly while fixing ERP sync details underneath.
◆ Current state
Merge ships weekly across Gateway, Unified and Agent Handler. October brought new Agent Handler connectors (Google Workspace, Ironclad, Zoom Phone, Meta Ads, TikTok for Business, Warp), Gateway support for GPT-6.1 Terra, Gemini 4 Argon and Mistral Large 4, custom prompt classifiers and a management API for security rules. Unified got NetSuite, QuickBooks, SharePoint and Jira sync fixes.
◆ Where it's heading
Merge is positioning Gateway and Agent Handler as the governed path for enterprise AI, adding admin controls and API management alongside catalog growth. The Unified integrations business keeps getting steady correctness fixes rather than new categories.
◆ Prediction
Expect more connectors and same-week model additions in Gateway, plus more management-API coverage; pricing or packaging changes are not visible in the entries.
