Release v2.0.0 · dhis2-chap/chap-core

Highlights

Chapkit self-registration: chapkit model services now self-register and auto-sync to the database on discovery, with auto-archival when a service disappears.
Breaking: removed the deprecated evaluate / evaluate-hpo CLI commands (CLIM-438).
PredictionSetup: new PredictionSetup abstraction for configuring a model with its data source.
Causal analysis: new causal CLI commands (build-counterfactual) and a counterfactual comparison plot.
Pluggable thresholds: new threshold calculation endpoint with a pluggable registry.
