What is NetBox?

NetBox adds a cooling data model — the first new infrastructure domain since power

After a 4.6 patch cycle spent almost entirely on GraphQL query cost and permission correctness, NetBox has opened its 4.7 line with a beta that is the opposite kind of release. It introduces cooling infrastructure as a first-class modeling domain, migrates nested group models off django-mptt onto a PostgreSQL ltree column, replaces the Service protocol/ports fields with a unified port_mappings structure, and raises the floor to PostgreSQL 15 and Redis 6. The breaking-change list runs longer than most NetBox releases run in total.

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.

NetBox adds a cooling data model — the first new infrastructure domain since power

◆ Current state

After a 4.6 patch cycle spent almost entirely on GraphQL query cost and permission correctness, NetBox has opened its 4.7 line with a beta that is the opposite kind of release. It introduces cooling infrastructure as a first-class modeling domain, migrates nested group models off django-mptt onto a PostgreSQL ltree column, replaces the Service protocol/ports fields with a unified port_mappings structure, and raises the floor to PostgreSQL 15 and Redis 6. The breaking-change list runs longer than most NetBox releases run in total.

◆ Where it's heading

The cooling model is deliberately shaped as a mirror of the existing power model — CoolingSource and CoolingFeed parallel PowerPanel and PowerFeed, CoolingIntake and CoolingOutflow parallel PowerPort and PowerOutlet, with CDUs and manifolds modeled as ordinary devices carrying those components. That symmetry says NetBox intends liquid cooling to be documented with the same rigor as power distribution, not bolted on as attributes. Underneath it, the ltree migration and the deferred search-index rebuild continue the performance thread of 4.6 by other means: instead of trimming queries inside the ORM, 4.7 is changing what the ORM sits on.

◆ Prediction

Expect at least one more 4.7 beta or release candidate before general availability, with the deprecated NestedGroupModel base class and the retained protocol/ports API fields the most likely sources of follow-up fixes as plugins migrate.

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.
