Migrating from 0.3 to 1.0

ActEval 1.0 is backward compatible with the documented 0.3 public API. Existing point-prediction, predictive-distribution, plotting, and decision-aware calls do not require changes.

Package and import names

The installation and import names are unchanged:

python -m pip install --upgrade acteval-insurance

import acteval as ae

New capabilities

  • Use bootstrap_evaluate() to add confidence intervals to existing metric selections.
  • Use paired_bootstrap_compare() when a named candidate must be compared with a reference on aligned resamples.
  • Use evaluate_by_segment(), compare_by_segment(), and evaluate_over_time() for portfolio monitoring.
  • Use prediction_drift() for fixed-reference score-distribution diagnostics.
  • Use result save_html() methods or export_table() for governed artifacts.

Compatibility notes

  • __version__ remains available from acteval and now has a single packaging source of truth.
  • The documented names in acteval.__all__ are covered by the 1.x stability policy.
  • summary() remains intended for people. Use to_dict() or to_dataframe() for integrations.
  • No composite score, automatic PSI threshold, or universal model ranking was introduced.
