 * Made use of ellipsis `...` in several function definitions safer using the **ellipsis** package
 
+* Bumped required version of R to 4.3.0 because the Matrix package, which is a dependency of ivreg now requires R 4.4.0. CRAN retain a binary version of Matrix 1.6-5 for the previous release of R, and so the minimum version can be 4.3.0 rather than 4.4.0.

 * Update **roxygen2** version used to generate documentation
