What is Hatchet?

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

What is k0s?

k0s writes the etcd certificate fix once and backports it down every branch

k0s ships version-only tags across four concurrent support branches, each a roll-up of backported pull requests and image bumps. The 1.36 branch has just taken Kubernetes 1.36.4 together with etcd certificate renewal for clusters using a custom etcd CA, a fix stopping k0s reset from unmounting the kubelet root directory, and image bumps for containerd, Calico, CoreDNS, Traefik and kine. The same etcd certificate work reached the 1.35 branch the same morning.

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

◆ Current state

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

◆ Where it's heading

Until now, running Hatchet meant running long-lived workers. The serverless package removes that requirement, so durable execution can run where JavaScript teams already deploy. The engine work points the same way: rate limits declared in the spec, safer worker acks, cheaper status queries. Patch cadence is still very high, often several engine tags a day, and much of it fixes durable-task edge cases.

◆ Prediction

Expect quick 0.1.x serverless releases as early users hit edge cases on each platform, and possibly matching Python handlers. More engine patches on durable-task shutdown and replay are likely.

k0s writes the etcd certificate fix once and backports it down every branch

◆ Current state

k0s ships version-only tags across four concurrent support branches, each a roll-up of backported pull requests and image bumps. The 1.36 branch has just taken Kubernetes 1.36.4 together with etcd certificate renewal for clusters using a custom etcd CA, a fix stopping k0s reset from unmounting the kubelet root directory, and image bumps for containerd, Calico, CoreDNS, Traefik and kine. The same etcd certificate work reached the 1.35 branch the same morning.

◆ Where it's heading

This is a maintenance distribution doing maintenance deliberately: a fix is written once and lands on 1.34, 1.35 and 1.36 within hours, with a bot authoring most of the roll-up. The two items in this batch that reach operators are both about not breaking a running cluster — certificates that would otherwise expire under a custom CA, and a reset path that was unmounting a directory it did not own. Feature work belongs to upstream Kubernetes; what k0s contributes is the packaging and the safety of the lifecycle commands around it.

◆ Prediction

Expect the branch-parallel pattern to continue, with the next Kubernetes patch releases arriving on 1.34, 1.35 and 1.36 in close succession rather than any one branch pulling ahead.
