CaseBasedReasoning 0.22

Bugfixes

• Weighted distance calculation was wrongly calculated, namely: $abs(sum(x-y))$ to $sum(abs(x-y))$. This has an effect on all linear models.

CaseBasedReasoning 0.4.1 (2026-02-27)

Breaking changes

• Redesigned API: snake_case function names (distance_random_forest, weighted_distance, terminal_nodes, as_dist_object). Old camelCase names still work but emit deprecation warnings.
• R6 field names changed to snake_case (endpoint, dist_matrix, order_matrix). Old names emit deprecation warnings.
• S3 generics added: predict(), print(), summary() for all model classes.

Bug fixes

• Fix off-by-one error in terminal node IDs for RF depth distance.
• Fix compilation on musl/Alpine Linux (no TBB fallback).
• Fix platform-dependent test failure in ordering tests.
• Replace broken URLs with stable DOI links.

Improvements

• Improved vignettes: added set.seed() for reproducibility, tightened prose.
• Removed archived pryr dependency; replaced with base do.call.
• Removed data.table dependency.
• Added CI/CD via GitHub Actions (macOS, Windows, Ubuntu).
