What is OpenKruise?

Seven workload APIs graduated to beta — then the feed went quiet for six months.

OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.

What is Retool?

Retool gives workflows their own run identity and sells self-hosted through Google Cloud.

Retool's first November week was about running and buying Retool in production. Workflows can now run as a chosen permission group, so scheduled and webhook-triggered runs no longer borrow a person's access. Self-hosted Enterprise can be deployed to GKE and billed through Google Cloud Marketplace, Microsoft SQL integration versions 1.0 and 2.0 were removed, and 4.88 reached the Edge channel. App testing entered public beta on November 3.

Seven workload APIs graduated to beta — then the feed went quiet for six months.

◆ Current state

OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.

◆ Where it's heading

This is a project consolidating rather than expanding — graduating APIs to beta is a commitment to stop changing their shape, and the accompanying features fill gaps in existing controllers rather than adding new ones. The pod resize protection is the one forward-looking item, tracking in-place resource resizing as it stabilizes upstream in Kubernetes. Whether the v1.9.0 line ever reached a stable release is not visible here.

◆ Prediction

The obvious next step is a stable v1.9.0 with the v1beta1 APIs finalized. The six-month gap since the last alpha is worth verifying against the project's actual release activity before reading it as a slowdown.

6.3

Retool gives workflows their own run identity and sells self-hosted through Google Cloud.

◆ Current state

Retool's first November week was about running and buying Retool in production. Workflows can now run as a chosen permission group, so scheduled and webhook-triggered runs no longer borrow a person's access. Self-hosted Enterprise can be deployed to GKE and billed through Google Cloud Marketplace, Microsoft SQL integration versions 1.0 and 2.0 were removed, and 4.88 reached the Edge channel. App testing entered public beta on November 3.

◆ Where it's heading

After the late-October app builder GA, Retool is filling in governance and operations: testing for generated apps, AI spend controls, service identities for automation and procurement through a cloud marketplace. Older integration versions are being retired on a schedule.

◆ Prediction

Expect more admin and governance controls around workflows and the app builder, plus further marketplace or self-hosted deployment options.
