# GLBFP 0.5.2

- Updated package authorship and citation metadata.

# GLBFP 0.5.1

## Features

- Added sparse-prefix computation for ASH, LBFP and GLBFP grid-count estimators.
- Added lowercase aliases (`ash()`, `lbfp()`, `glbfp()` and corresponding grid functions).
- Added `as.data.frame()` helpers for grid objects.
- 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.

# GLBFP 0.3.0
