kdensity 1.2.0 (2026-05-04)

• New closed-form bandwidth selector "HS", based on Hallberg Szabadváry’s beta reference rule (arXiv:2601.19553). It is now the default bandwidth for the bias-corrected beta kernel with a uniform or constant start, with a fallback heuristic when the rule’s moment conditions are not satisfied.
• RHE no longer depends on the EQL package; the Hermite polynomials are evaluated inline (matches the previous numeric output to ~1e-12).
• Trimmed dependencies: EQL removed from Imports; assertthat, testthat, extraDistr, and other build-time helpers no longer required at install time.
• Internal cleanup: the R/ source layout is consolidated into bandwidths.R, kernels.R, starts.R, and helpers.R; no user-visible API changes.

kdensity 1.1.1 (2025-02-18)

• Added support for update of univariateML to version 1.5.
• There are breaking changes in the new version univariateML, but only for this package.
• The new package update is designed to work with univariateML less than 1.5 as well.

kdensity 1.1.0 (2019-01-10)

• Journal of Open Source Software Release.
• Safer kdensity object structure.
• Cleaned up readme and documentation.

kdensity 1.0.1 (2019-07-11)

• Fixed the laplace kernel.
• kdensity: Added error message when the normalization constant fails to be accurate enough and a tolerance parameter to control it.
• Better error messages when data is not in the support of the parametric starts.
