+# AGENTS.md
+
+This repository is an R package. Keep changes small, package-oriented, and easy to verify locally.
+
+## Core Commands
+
+- `just test`: run the testthat suite.
+- `just check`: run `R CMD check` with `--as-cran` and `--no-manual`.
+- `just coverage`: print coverage and write a readable `coverage.html`.
+- `just readme`: render `README.md` from `README.Rmd`.
+- `just clean`: remove local check, coverage, tarball, and generated test artifacts.
+
+## Repo Conventions
+
+- `README.md` is generated from `README.Rmd`. Edit `README.Rmd` if the rendered README needs to change.
+- Package documentation in `man/` is generated from roxygen comments in `R/`.
+- Keep top-level developer files such as `AGENTS.md` and `Justfile` out of package builds.
+- `tests/testthat/Rplots.pdf` is a disposable artifact. Recipes should remove it automatically.
+
+## Change Scope
+
+- Prefer focused edits over wide refactors.
+- Add or extend tests for behavior changes.
+- Before a version bump, make sure `DESCRIPTION`, docs, and CI reflect the current package behavior.

DESCRIPTION

@@ -1,3 +1,19 @@
+## 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.
