What is filtro?
filtro moves to S7 and multiplies its feature-scoring methods in a single release.
filtro supplies feature-selection filter scores for the tidymodels stack. Version 0.2.0 adds five scoring methods — correlation, random forest importance, information gain, ROC AUC and cross tabulation — and moves the package from S3 to S7. It also gains a ranking layer: show_best_score_* and rank_best_score_* helpers for a single score, plus desirability-function helpers for optimising across several scores at once.
What is Fulcrum?
Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.
Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. Feature work is thin right now; the visible surface is stabilization around a mapping engine migration already in flight.

filtro moves to S7 and multiplies its feature-scoring methods in a single release.
◆ Current state
filtro supplies feature-selection filter scores for the tidymodels stack. Version 0.2.0 adds five scoring methods — correlation, random forest importance, information gain, ROC AUC and cross tabulation — and moves the package from S3 to S7. It also gains a ranking layer: show_best_score_* and rank_best_score_* helpers for a single score, plus desirability-function helpers for optimising across several scores at once.
◆ Where it's heading
The package is being built out on two axes at once — the catalogue of scores, and the machinery for choosing between them. The desirability functions are the more telling half, since they assume users will filter on several criteria rather than one. Adopting S7 while still pre-1.0 suggests the object model is being settled before the API is frozen.
◆ Prediction
Expect more scoring methods on the same S7 interface and a 1.0 release once the score and ranking APIs stop moving; the ranking helpers' naming is the most likely thing to change first.
Fulcrum
6.3ANALYTICS
Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.
◆ Current state
Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. Feature work is thin right now; the visible surface is stabilization around a mapping engine migration already in flight.
◆ Where it's heading
The direction is a full consolidation onto Esri. The legacy Google Maps engine is being retired on September 1 with automatic migration for anyone who hasn't switched, and Esri now carries Google's satellite and street basemaps so the imagery argument is neutralized. Underneath, the mobile SDK moved to ArcGIS 300.0.0 and ONNX on-device inference was dropped for a new INFERENCE format with labels.txt support. Offline is the second thread: downloadable layers can now be updated in place rather than deleted and recreated.
◆ Prediction
Expect the weeks before September 1 to stay dominated by migration-shaped fixes and Esri feature parity work, with the MMPK layer and Photo FastFill early-access programs the most likely to graduate to general availability next.
