Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.
Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.
Hatchet is shipping engine patches almost daily as it opens the scheduler to outside operators.
Hatchet is a task orchestration engine with durable execution, DAGs, cron and rate limits, shipped as a fast-moving open-source release train. In three days it cut seven engine releases, most of them narrow fixes to the DAG operator, durable waits, error passthrough and the cron ticker. The Python SDK keeps pace with flow-control features.

Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.
The pattern is to centralize and codify: settings move from individual agents to clusters, and from the UI to Terraform and APIs, and capabilities such as caching move from plugins into the agent itself. Test Engine is turning into a programmable flaky-test management layer instead of a dashboard.
Expect more Test Engine monitors and actions that can be managed in code, and cache controls such as eviction and scoping, now that Cache is GA.

In three days it cut seven engine releases, most of them narrow fixes to the DAG operator, durable waits, error passthrough and the cron ticker. The Python SDK keeps pace with flow-control features.
The 0.113.0 serverless operator, a gRPC service that lets operators run outside the engine, set the direction: Hatchet is turning its scheduler into a platform that external runtimes plug into. The patches since then harden that path, especially durable streams and DAG output handling, and add finer flow control such as pausing rate-limited queues.
Expect more durable-stream and operator fixes in the 0.113–0.114 line, followed by SDK support that makes out-of-process operators usable without hand-written gRPC.
