What is Fulcrum?
Fulcrum is consolidating on Esri, with Google Maps gone September 1
The mapping stack is the whole story right now: ArcGIS SDK 300.0.0 on iOS, the latest ArcGIS and deck.gl on web, and a hard cutover date after which any organization still defaulting to Google Maps is switched to Esri automatically. The mobile releases in this window are almost entirely map and location fixes — basemap loading, offline symbol styling, location resolution that blocked saves. On-device inference quietly changed format, dropping ONNX.
What is OpenMC?
OpenMC's random ray solver has gone from new arrival to the centre of every release
OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.

Fulcrum is consolidating on Esri, with Google Maps gone September 1
◆ Current state
The mapping stack is the whole story right now: ArcGIS SDK 300.0.0 on iOS, the latest ArcGIS and deck.gl on web, and a hard cutover date after which any organization still defaulting to Google Maps is switched to Esri automatically. The mobile releases in this window are almost entirely map and location fixes — basemap loading, offline symbol styling, location resolution that blocked saves. On-device inference quietly changed format, dropping ONNX.
◆ Where it's heading
One platform bet runs through everything: Esri as the single map engine, with Google's satellite, hybrid, and street imagery retained as basemap options so the migration costs users imagery choice, not capability. The current release cadence is stabilization work paying down that migration rather than new ground.
◆ Prediction
Expect map and location fixes to keep dominating releases through the September 1 cutover, with the Esri-only capabilities already listed — snapping, ArcGIS Feature Service connectivity, offline basemaps — becoming the default surface rather than the alternative one.

2.5ANALYTICS
OpenMC's random ray solver has gone from new arrival to the centre of every release
◆ Current state
OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.
◆ Where it's heading
The project is layering a deterministic-adjacent solver alongside its Monte Carlo core rather than replacing it, and the ratio of random-ray work to core-solver work in each release keeps rising. In parallel it is packaging expert workflows into objects — R2SManager is the clearest case, turning a multi-stage shutdown dose calculation into a class rather than a recipe. The Python API is where most of that packaging surfaces, and it is also where the compatibility breaks land, with the minimum version moving to 3.12 in 0.16.0.
◆ Prediction
Given that every release since 0.15.0 has expanded the random ray solver's feedback and tally coverage, the next is likely to continue closing the gap between it and the main solver's feature set. The notes do not indicate whether it is intended to become a default path.
