What is Nautobot?

Nautobot 3.3 alpha adds API rate limits while 3.2.9 stops cross-user token reads.

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, and closed three more ways to read fields marked sensitive. The same day v3.3.0a1 opened the next feature line with REST API rate limiting, JSON and YAML exports, primary IPs that need no interface, and a breaking change to IP assignments.

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.

Nautobot 3.3 alpha adds API rate limits while 3.2.9 stops cross-user token reads.

◆ 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, and closed three more ways to read fields marked sensitive. The same day v3.3.0a1 opened the next feature line with REST API rate limiting, JSON and YAML exports, primary IPs that need no interface, and a breaking change to IP assignments.

◆ Where it's heading

Since September the work has been a permissions and template-sandbox audit, with each release closing gaps the previous one exposed. 3.3 is the first feature line since then, and its headline additions (rate limiting, timing headers, job duration summaries, export field control) come from running Nautobot at scale and through its API.

◆ Prediction

Expect more 3.3 alphas and betas while the 3.2 and 2.4 lines keep receiving paired security releases; the sensitive-fields controls added in 3.2.5 will likely keep generating bypass fixes.

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.
