What is Pacemaker?

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

What is Hatchet?

Hatchet chases DAG crash loops through three engine patches in a day.

Hatchet added sandboxes, Labs switches and cloud MFA in early November. The week since has been engine reliability: v0.120.3 batches DAG step triggers, v0.120.4 fixes stranded match rows and prunes database partitions before locking, and v0.120.5 removes another cause of DAG crash loops. Python SDK 1.46.0 makes it easier to unit-test tasks and passes failures to cleanup dependencies.

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

◆ Current state

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

◆ Where it's heading

The cluster's internal transport is being rebuilt on the assumption that the network between nodes is not trusted. Authentication and encryption arrived first, and the fixes that followed, overflow guards and a maximum remote message size, are the hardening pass on the same code paths. Release discipline is heavy and visible: each version ships a release candidate with an identical commit set days earlier, and every 3.0 release documents the regressions it introduced and where they were fixed.

◆ Prediction

Remote CIB operations now support both X509 certificates and PSK, and the recent fixes all sit in message framing and size limits; further work is most likely to continue in that message-handling code rather than adding another authentication mechanism.

6.3

Hatchet chases DAG crash loops through three engine patches in a day.

◆ Current state

Hatchet added sandboxes, Labs switches and cloud MFA in early November. The week since has been engine reliability: v0.120.3 batches DAG step triggers, v0.120.4 fixes stranded match rows and prunes database partitions before locking, and v0.120.5 removes another cause of DAG crash loops. Python SDK 1.46.0 makes it easier to unit-test tasks and passes failures to cleanup dependencies.

◆ Where it's heading

After a burst of features, Hatchet is tuning the engine under load: fewer locks, batched triggers and crash-loop fixes. The SDKs are getting testing and correctness work to match.

◆ Prediction

Expect more v0.120.x patches on DAG handling, then a sandbox package out of release candidate.
