hubData vs modelbpp: at a glance
What is hubData?
The Arrow data layer for forecast hubs, spending its releases on cloud and materialisation bugs.
hubData is the access layer for hubverse forecasting hubs, connecting to local and cloud-stored model output through Arrow and handing back lazy connections or materialised tibbles. Its releases divide sharply between schema and utility additions in the 1.x line and, more recently, a run of defect fixes in the cloud and Arrow integration. Two of those fixes involved data being silently wrong rather than an error being raised.
What is modelbpp?
A structural-equation model comparison package whose feed carries links, not release notes.
modelbpp computes model-implied Bayesian posterior probabilities for structural equation models, one of several R packages from the same author covering moderation, mediation and model-comparison workflows. Its release feed is not a changelog: every entry points at the package website rather than describing what changed, so the substance of each release is not visible here. Version numbering has moved steadily from 0.1.x to 0.4.0 across roughly three years.

hubData
0.0ANALYTICS
The Arrow data layer for forecast hubs, spending its releases on cloud and materialisation bugs.
◆ Current state
hubData is the access layer for hubverse forecasting hubs, connecting to local and cloud-stored model output through Arrow and handing back lazy connections or materialised tibbles. Its releases divide sharply between schema and utility additions in the 1.x line and, more recently, a run of defect fixes in the cloud and Arrow integration. Two of those fixes involved data being silently wrong rather than an error being raised.
◆ Where it's heading
The package has largely finished adding surface and is now paying down the cost of sitting on top of Arrow and S3: ALTREP-backed columns escaping into user sessions, cloud hubs whose declared format differs from what is actually written, and metadata arrays parsing inconsistently. Each fix narrows the gap between what the storage layer does and what an R user expects. The performance-motivated default flip in 2.0.0 points the same way, prioritising large cloud hubs over conservative local behaviour.
◆ Prediction
Expect continued fixes at the Arrow and cloud boundary, particularly where declared hub configuration and actual stored format disagree, which has now produced defects twice.
modelbpp
2.5ANALYTICS
A structural-equation model comparison package whose feed carries links, not release notes.
◆ Current state
modelbpp computes model-implied Bayesian posterior probabilities for structural equation models, one of several R packages from the same author covering moderation, mediation and model-comparison workflows. Its release feed is not a changelog: every entry points at the package website rather than describing what changed, so the substance of each release is not visible here. Version numbering has moved steadily from 0.1.x to 0.4.0 across roughly three years.
◆ Where it's heading
What can be read from this feed is cadence rather than content — releases clustered noticeably more tightly through 2026 than in the preceding two years, with three in five months against two in the prior eighteen. Because the entries carry no detail, any statement about what is being built would be speculation. The pattern of a stable CRAN package accelerating its release rate is the only reliable signal available.
◆ Prediction
The feed does not describe its changes, so the direction of development cannot be read from these entries; the accelerating 2026 cadence is the only thing it supports.
