+## R CMD check results

+0 errors | 0 warnings | 0 note
+
+- This is a new release (version 1.0.1).
+- Bug fix: `rd_checkbox` now correctly evaluates branching logic after previous `rd_factor` transformations.
+- New feature: `redcap_data()` now has a `sep` argument to allow specifying the CSV field separator for the dictionary file.
+- No changes in dependencies.
