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.

What is Kata Containers?

Kata Containers 4.3 fixes a guest-to-host escape and tightens annotation handling.

Kata Containers ships monthly, and 4.3.0 (October 21) carries two security fixes: a permissive annotation allowlist that could cause unintended host and guest changes (CVSS 7.9, existing installs need a config review) and out-of-bounds access in Dragonball virtio drivers that allowed guest-to-host escape (CVSS 6.4). The same release restricts containerd pod annotations, bumps the guest kernel to 6.18.52 and ships more NVIDIA GPU runtime components. 4.3.1 followed the same day with eMudhra certificate exclusion.

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.

5.0

Kata Containers 4.3 fixes a guest-to-host escape and tightens annotation handling.

◆ Current state

Kata Containers ships monthly, and 4.3.0 (October 21) carries two security fixes: a permissive annotation allowlist that could cause unintended host and guest changes (CVSS 7.9, existing installs need a config review) and out-of-bounds access in Dragonball virtio drivers that allowed guest-to-host escape (CVSS 6.4). The same release restricts containerd pod annotations, bumps the guest kernel to 6.18.52 and ships more NVIDIA GPU runtime components. 4.3.1 followed the same day with eMudhra certificate exclusion.

◆ Where it's heading

Since the Rust runtime became the default in 4.0, releases have gone to GPU packaging, kata-deploy's move to a job-based deployment mode and policy hardening in genpolicy. 4.2.0 moved the rootfs to Ubuntu 26.04 and passed QEMU block and VFIO devices by file descriptor; 4.3.0 continues with rootless VMM provisioning and guest-pulled image verification.

◆ Prediction

4.4.0 should land around November 17, given the documented target of the first Tuesday after the 15th. Expect more NVIDIA GPU packaging work, a thread in 4.1, 4.2 and 4.3.
