     Contains instructions of multiplicity graph and graphical testing for
     group sequential design, with necessary unit testing using 'testthat'.

+## Improvements
+
+- Added method references DOI to the description field of the `DESCRIPTION` file.
+- Removed redundant `\dontrun{}` from examples.
+- Replaced `cat()` with `message()` where suppression options like `verbose` are
+  not available, except for printing raw R Markdown content in vignettes,
+  which requires `cat()`.
+- Removed setting `options(warn=-1)` and `options(warn=0)` in function.
+- Reset the user's `options()` in vignettes after changing it.
