Changes in version 0.5.2.9000 - Updated package authorship and citation metadata for the GitHub development version. Changes in version 0.5.1 (2026-06-16) Features - Added sparse-prefix computation for ASH, LBFP and GLBFP grid-count estimators. - Added compute_Di() and compute_di() for fixed-grid leave-one-out self-support scores. - Added lowercase aliases (ash(), lbfp(), glbfp() and corresponding grid functions). - Added as.data.frame() helpers for grid and D_i score objects. - Added plot.glbfp_di() for leave-one-out score diagnostics. - Added a hexagonal package logo and expanded pkgdown article structure. - Added test infrastructure (testthat edition 3) and regression/invariant tests. - Added S3 helpers for summary() and predict() on fit/grid objects. - Added two publication-oriented vignettes (introduction and validation). - Added reproducible benchmark scripts in benchmarks/ and validation helpers in inst/bench. - Added pkgdown and coverage workflows. - Added citation files (CITATION.cff, inst/CITATION) and cran-comments.md. - Added pre-R Journal preparation files in dev/ and rjournal-prep/. Fixes - Strengthened input validation (finite numeric checks, shape checks, explicit errors). - Improved numerical robustness in compute_bi_optim() for near-singular covariance matrices. - Fixed plotting methods for irregular custom grids and metadata handling. - Fixed broken references in plot.ASH_estimate(). - Reduced duplicated S3 plotting and printing code through shared internal helpers. Changes in version 0.4.0 - Added standard deviation and confidence interval output for *_estimate functions. Changes in version 0.3.0 - Internal maintenance release. Changes in version 0.2.0 - Fixed errors in ASH() and GLBFP(). Changes in version 0.1.0 - Initial release.
