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 Split.io?

Split FME's March releases pull feature flags fully into the Harness DevOps platform.

Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.

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.

Split FME's March releases pull feature flags fully into the Harness DevOps platform.

◆ Current state

Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.

◆ Where it's heading

FME is becoming a first-class part of the Harness DevOps surface rather than a standalone feature-flag tool. Pipeline-native flag operations, policy-as-code governance, and archiving as a managed lifecycle state all reflect a single direction: feature flags as a governed, audited, and pipeline-integrated component of the deployment system. The standalone Split UX is fading into Harness conventions.

◆ Prediction

Expect more Harness-platform conventions to land on FME — RBAC unification, environments and pipelines parity, OPA policy templates shipped out of the box, and observability tying flag changes back into deploy-failure/MTTR dashboards. Standalone-Split UX surfaces will likely be retired further.
