This log follows the package versions declared in pyproject.toml.

v0.4.3 — 2026-06-29

Published the canonical supervised-region API from the package root so fresh and upgraded Colab runtimes can import all three region clusterers.
Made the packaged Colab notebook install the exact release, verify its exports, and run independently of repository-local result files.
Added a self-contained Diabetes continuous-target example with regional η², coverage, unmatched rate, dispersion reduction, and separate forest R²/RMSE diagnostics.
Normalized low-level multiclass parameters to leaf_percentile, low_leaf_fraction, max_regions_per_class, and rule_score; legacy spellings remain available with FutureWarning.
Confirmed that deprecated classes, methods, and attributes remain migration aliases throughout 0.4.x and are scheduled for removal in 0.5.0.
Added wheel-level import, stale-install upgrade, and isolated notebook execution regression coverage.

Version note: 0.4.2 was not published; 0.4.3 is the first public release after the internal 0.4.1 API transition.

Redefined the canonical estimators as supervised region clusterers: InsideForestRegionClusterer, InsideForestClassRegionClusterer, and InsideForestContinuousRegionClusterer.
The forest now generates candidate leaves only. predict returns cluster IDs, unmatched observations receive -1, and the canonical API has no class/value prediction fallback.
Added canonical region tables, assignment details, transformations, quality reports, persistence, class-aware diagnostics, continuous-target statistics, AMI scoring for categorical targets, and η² scoring for continuous targets.
Reserved labels_ for training cluster assignments and moved per-region measurements to region_metrics_.
Made branch aggregation opt-in and initialized the canonical estimators with branch_aggregation="none".
Deprecated InsideForestClassifier, InsideForestMulticlassClassifier, and InsideForestRegressor as migration aliases.
Updated the bilingual documentation, Colab notebook, benchmarks, package metadata, migration notes, and acceptance tests for the regional contract.

Previous public package release, based on the legacy classifier/regressor interfaces.
