What is cvms?

A cross-validation package whose real development has moved to its plotting function

cvms runs repeated cross-validation over model formulas and reports comparable metrics. The 2.0.0 release was a breaking correctness fix: every function accepting fold_cols mismatched training and testing data when fold indices were non-sequential, did not start at 1, or were strings, because the iteration index was compared against the raw fold value rather than its factor level index. 2.0.1 restored coefficient extraction for nnet::multinom and mixed models by supplying an environment containing the training data, and followed lme4's move of findbars() into the reformulas package.

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.

A cross-validation package whose real development has moved to its plotting function

◆ Current state

cvms runs repeated cross-validation over model formulas and reports comparable metrics. The 2.0.0 release was a breaking correctness fix: every function accepting fold_cols mismatched training and testing data when fold indices were non-sequential, did not start at 1, or were strings, because the iteration index was compared against the raw fold value rather than its factor level index. 2.0.1 restored coefficient extraction for nnet::multinom and mixed models by supplying an environment containing the training data, and followed lme4's move of findbars() into the reformulas package.

◆ Where it's heading

Two threads run in parallel and only one is about cross-validation. The plotting function plot_confusion_matrix() has absorbed most feature work since 1.5.0 - custom gradient palettes, intensity limits, per-tile settings, dynamic font colors keyed to value thresholds, and arguments that accept functions rather than constants - to the point where a companion web application exists for using it without code. The cross-validation core, by contrast, sees maintenance: upstream compatibility fixes for pROC, ggnewscale and ggplot2, and the fold-matching correction that finally forced a major version.

◆ Prediction

Expect continued option growth in the confusion matrix plotting surface, since that is where nearly every release since 1.5.0 has spent its changes, with core cross-validation changes arriving only as upstream packages force them.

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.
