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. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.
What is momentuHMM?
The animal-movement HMM workhorse, feature-frozen since 2021 and coasting on compiler patches
momentuHMM fits hidden Markov models to animal telemetry — multiple data streams, measurement error, temporally irregular tracks, hierarchical and mixture structures. It is one of the reference implementations in movement ecology and is cited as such. Its capability set has been essentially fixed since 2021; the last four years of releases are compiler, dependency and CRAN metadata work.

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. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.
◆ Where it's heading
The direction is a full consolidation onto Esri. The legacy Google Maps engine retires on September 1 with automatic migration for anyone who has not 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 gave way to a new INFERENCE format. Two capabilities are visibly staged behind early access rather than shipped: Photo FastFill, and a GPS integration still described as Alpha.
◆ Prediction
Expect the weeks before September 1 to stay dominated by migration-shaped fixes and Esri parity work, with Photo FastFill the nearer of the two early-access programs to general availability given it is already running in shipped builds.

The animal-movement HMM workhorse, feature-frozen since 2021 and coasting on compiler patches
◆ Current state
momentuHMM fits hidden Markov models to animal telemetry — multiple data streams, measurement error, temporally irregular tracks, hierarchical and mixture structures. It is one of the reference implementations in movement ecology and is cited as such. Its capability set has been essentially fixed since 2021; the last four years of releases are compiler, dependency and CRAN metadata work.
◆ Where it's heading
The development arc peaked with 1.5.0 in 2019, which brought hierarchical HMMs, discrete individual random effects and multivariate normal data streams, and effectively closed with 1.5.4 in 2021. What follows is a maintenance tail driven entirely by other people's changes: RcppArmadillo deprecating a function, Brobdingnag unexporting one, crawl dropping an import, CRAN asking for metadata edits. The package is stable in the sense that matters to its users and dormant in the sense that matters to its roadmap.
◆ Prediction
On this pattern the next release will be another upstream-forced patch rather than new modelling capability, unless a maintainer change or a new methods paper reopens development.
