# RenyiExtropy 0.4.0

* Improved input validation across all functions: each check now produces a
  distinct, informative error message that names the offending argument.
* Added `anyNA()` guards to all functions accepting probability vectors or
  matrices, so `NA`/`NaN` inputs are caught early.
* Added `is.matrix()` checks to `joint_entropy()`, `conditional_entropy()`,
  and `conditional_renyi_extropy()`.
* `kl_divergence()` and `cross_entropy()` now emit a `warning()` (rather than
  silently replacing) when a zero entry in `q` is paired with a positive
  entry in `p`.
* Expanded `@examples` sections for all exported functions.
* Updated `DESCRIPTION`: added `URL` and `BugReports` fields; removed
  `LazyData` (no data files shipped).
* Comprehensive `testthat` test suite covering correctness, limit cases, and
  all input-validation error/warning paths.
