What is Harbor?

Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.

Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.

What is Hatchet?

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.

Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.

◆ Current state

Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.

◆ Where it's heading

Harbor's recent releases are split between security hardening and undoing the parts of that hardening that broke real deployments. Both supported lines now carry the rollbacks, and new work is CVE fixes rather than features.

◆ Prediction

Expect 2.14.6 and 2.15.4 finals shortly; the entries don't show a 2.16 feature release yet.

5.0

Hatchet is shipping engine patches almost daily as it opens the scheduler to outside operators.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
