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 Nautobot?

Nautobot 3.3 alpha 2 adds test helpers and a cable location filter after 3.2.9's token-leak fix.

Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks; on November 9 v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys. The 3.3 feature line opened the same day with REST API rate limiting and JSON and YAML exports. v3.3.0a2 on November 13 mostly adds Playwright helpers for App test suites, along with a location filter on the cable connection form and a fix for a login page that reloaded every 15 seconds.

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.

Nautobot 3.3 alpha 2 adds test helpers and a cable location filter after 3.2.9's token-leak fix.

◆ Current state

Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks; on November 9 v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys. The 3.3 feature line opened the same day with REST API rate limiting and JSON and YAML exports. v3.3.0a2 on November 13 mostly adds Playwright helpers for App test suites, along with a location filter on the cable connection form and a fix for a login page that reloaded every 15 seconds.

◆ Where it's heading

3.3 is moving through alphas quickly, four days apart, while the security audit continues on the stable lines. The Playwright helpers suggest Nautobot wants App developers to test against its UI with shared tooling rather than custom scripts.

◆ Prediction

More 3.3 alphas or a beta should follow within weeks, alongside the next pair of 3.2.x and 2.4.x security releases on the two-week rhythm.
