What is performance?

performance keeps adding ways to check a model you have already fitted.

performance is at 0.17.1, which added check_priors() for prior predictive checks on Bayesian models and gave check_overdispersion(), check_model() and check_predictions() arguments to control residual type and plot range. The releases before it are a similar mix: a -2LL criterion column in test_likelihoodratio(), Bayesian predictive checks routed through modelbased, and in 0.16.0 a set of breaking renames including RMSA to the correct RMSR.

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.

performance keeps adding ways to check a model you have already fitted.

◆ Current state

performance is at 0.17.1, which added check_priors() for prior predictive checks on Bayesian models and gave check_overdispersion(), check_model() and check_predictions() arguments to control residual type and plot range. The releases before it are a similar mix: a -2LL criterion column in test_likelihoodratio(), Bayesian predictive checks routed through modelbased, and in 0.16.0 a set of breaking renames including RMSA to the correct RMSR.

◆ Where it's heading

Two consistent habits. Diagnostics keep gaining arguments to narrow what is examined — ppc_range, x_limits, maximum_dots, show_ci — which reads as a package being used on models large and awkward enough that the defaults stopped working. And simulated residuals via DHARMa keep displacing standard ones as the basis for the checks themselves.

◆ Prediction

With check_priors() newly added and Bayesian predictive checks now routed through modelbased, the next release most likely extends the Bayesian diagnostic set rather than reworking the frequentist checks.

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.
