What is Fulcrum?

Fulcrum's mobile train is all Esri migration cleanup, with on-device inference quietly changing format.

Fulcrum ships iOS, Android, and web releases on a near-weekly cadence, and this stretch is dominated by mapping work following the Google Maps retirement announced for September. Recent builds upgraded to ArcGIS SDK 300.0.0, moved the web map engine to current ArcGIS and deck.gl versions, and worked through the resulting stability issues — basemap loading, location resolution, black map screens, panning and zooming performance. The most consequential change is easy to miss: ONNX support for on-device machine learning inference was removed in favor of a new INFERENCE format that reads labels from an uploaded labels.txt.

What is timetk?

timetk swallowed anomalize whole, then went quiet for two years

timetk handles time series wrangling, visualization, and feature engineering in a tidyverse idiom. Its defining recent move was absorbing the anomalize package outright in 2.9.0, bringing anomaly detection, cleaning, and the associated plots inside timetk rather than leaving them in a sibling package. Development then paused for nearly two years before 2.9.1, a robustness and documentation release.

Fulcrum's mobile train is all Esri migration cleanup, with on-device inference quietly changing format.

◆ Current state

Fulcrum ships iOS, Android, and web releases on a near-weekly cadence, and this stretch is dominated by mapping work following the Google Maps retirement announced for September. Recent builds upgraded to ArcGIS SDK 300.0.0, moved the web map engine to current ArcGIS and deck.gl versions, and worked through the resulting stability issues — basemap loading, location resolution, black map screens, panning and zooming performance. The most consequential change is easy to miss: ONNX support for on-device machine learning inference was removed in favor of a new INFERENCE format that reads labels from an uploaded labels.txt.

◆ Where it's heading

This is a platform consolidation being paid down one point release at a time. Having committed to Esri, Fulcrum is absorbing the instability that came with it, and each release reads as fixes to symptoms of the same migration. Underneath, the offline and field-capture story continues to get real attention — downloaded offline map layers can now be updated in place, and Photo FastFill moved to background processing so it no longer blocks editing.

◆ Prediction

Expect the release notes to stay fix-dominated through the September Google Maps cutoff, with the migration-related map defects tapering after it passes. Photo FastFill leaving early access is the most likely next substantive item.

timetk swallowed anomalize whole, then went quiet for two years

◆ Current state

timetk handles time series wrangling, visualization, and feature engineering in a tidyverse idiom. Its defining recent move was absorbing the anomalize package outright in 2.9.0, bringing anomaly detection, cleaning, and the associated plots inside timetk rather than leaving them in a sibling package. Development then paused for nearly two years before 2.9.1, a robustness and documentation release.

◆ Where it's heading

The trajectory before the pause was consolidation: fold in adjacent functionality, then make the visualization layer handle many series at once via trelliscopejs, then broaden feature generation with tk_tsfeatures(). The recent release works on the least glamorous layer — internal generics so date parsing and sequence generation behave consistently across Date, POSIXct, hms, yearmon, and yearqtr — which is the kind of foundation work a package does when it has accumulated too many special cases. The long gap and the CI-refresh content suggest maintenance attention rather than a new direction.

◆ Prediction

The stated gap is the unimplemented twitter method for anomalize(), which is the one concrete outstanding item the release notes name; beyond that the recent work points to consolidation rather than expansion.
