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 mizer?

After two and a half years dormant, mizer shipped three major versions in seven weeks.

The size-spectrum fish modelling package sat at 2.5.0 from December 2023 until June 2026, then released 3.0.0, 3.1.0 and 3.2.0 in the space of seven weeks. The three releases divide cleanly: 3.0.0 added biological realism through a diffusion term in the McKendrick-von Foerster equation, 3.1.0 added an opt-in second-order numerical scheme in size, and 3.2.0 rebuilt how species and resource parameters are set. Backward compatibility is handled carefully throughout — the experimental scheme is off by default and the first-order path is byte-identical to previous versions.

6.3

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.

5.0

After two and a half years dormant, mizer shipped three major versions in seven weeks.

◆ Current state

The size-spectrum fish modelling package sat at 2.5.0 from December 2023 until June 2026, then released 3.0.0, 3.1.0 and 3.2.0 in the space of seven weeks. The three releases divide cleanly: 3.0.0 added biological realism through a diffusion term in the McKendrick-von Foerster equation, 3.1.0 added an opt-in second-order numerical scheme in size, and 3.2.0 rebuilt how species and resource parameters are set. Backward compatibility is handled carefully throughout — the experimental scheme is off by default and the first-order path is byte-identical to previous versions.

◆ Where it's heading

Two threads run through the 3.x line. The first is numerical: diffusion, then higher-order accuracy in both size and time, with explicit warnings that enabling them shifts diagnostics and may require recalibration. The second is making the package composable — extensions now work regardless of load order, and parameter assignment propagates to the derived rate arrays instead of being silently discarded. That second thread reads as the more consequential one: the 3.2.0 notes describe scalar edits that previously vanished and now accumulate, which is the kind of fix that changes what published model configurations actually computed.

◆ Prediction

Expect the experimental second-order scheme to move toward default-on once recalibration guidance exists, and the patch line to keep absorbing the documentation and website gaps that 3.2.1 started on.
