densityratio 0.2.3 (2026-07-14)

• update loocv procedure in ulsif to work with unconstrained kernel weights
• update lhss to perform unconstrained optimization (aligned with loocv procedure of ulsif)
• small formal check to stop when negative regularization parameters are supplied

densityratio 0.2.2 (2025-07-18)

• update plot_bivariate() to depend on ggh4x to remove empty panels, instead of a grob (such that it remains a ggplot) object
• update link in readme

• patch test files to work with the new upcoming ggplot release
• update link readme
