Fulcrum
Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.
A side-by-side editorial comparison of cubist and dbt Core — release velocity, themes, recent moves, and the top alternatives to consider.
The R port of Quinlan's Cubist gets reproducibility fixes, not new modelling
Cubist is the R interface to Quinlan's rule-based regression model, wrapping the original C sources behind an R API and feeding the tidymodels rules package. The 0.6.0 release adds a strip_time_stamps control that removes date, time and duration information from model output, and now errors rather than silently misbehaving when a date or date-time column is passed. Error reporting moves from base stop() and warning() to cli.
dbt Fusion's second beta is adapter work: ClickHouse gets materializations, indexes, and catalogs
Fusion 2.0 is in its second beta, and the content has shifted from engine capability to adapter coverage. beta.2 is almost entirely ClickHouse — Dictionary materialization, index definitions, additional settings, a relation-scoped catalog macro that fixes --write-catalog, and a seed nullability fix — plus Entra bearer-token authentication for the Fabric adapter. Behind it sits the August 14 backport wave, which cut releases for 1.1 through 1.8 in a single day to deliver one deprecated-version warning.

The direction is custodial: this is a mature algorithm with a stable definition, so the work is making a decades-old C codebase behave predictably inside a modern R workflow. The reproducibility thread is the clearest one — embedded timestamps mean two identical models compare as different objects, which breaks caching, testing and any workflow that hashes results. Alongside it runs slow C hygiene, from keyword symbol overwrites in 0.5.0 to unused-variable warnings in 0.6.0.
Expect continued small maintenance releases tracking CRAN compiler requirements and the needs of the rules package, with no change to the modelling algorithm itself.

The two ends of this project are pulling apart cleanly. Old branches are being prepared for retirement — a deprecation warning fanned across eight of them, Python 3.8 testing dropped from 1.4 through 1.6 — while Fusion accumulates the adapter breadth it needs to be a credible replacement. beta.1 proved the engine could bind without a catalog; beta.2 is the unglamorous follow-through of making a specific warehouse work properly.
Expect further beta releases filling in per-adapter gaps rather than new engine capability, and formal end-of-life notices for the branches that just took the deprecation warning.
