   * `wisca()` now follows Bielicki *et al.* (2016) more strictly by using $\text{Beta}(1, 9999)$ for intrinsically resistant pairs, forcing near-zero susceptibility regardless of observed data (based on EUCAST Expected Resistant Phenotypes)
   * Fixed a bug where both functions failed without the `antimicrobials` argument if `tidyselect` was not available, e.g., for binary installations without `dplyr`
   * Isolates of unknown species are now included in grouped antibiograms and in `wisca()`, as they already were in traditional antibiograms. They were previously excluded silently, with the warning "invalid microorganism code, NA generated". This can change WISCA coverage estimates.
+  * Grouped traditional antibiograms now show the (translated) pathogen names, as ungrouped antibiograms do, instead of microorganism codes
 * Resistance and susceptibility calculation
   * New argument `guideline` (default: the `AMR_guideline` option, otherwise EUCAST) in `susceptibility()`, `resistance()`, `count_df()`, `proportion_df()`, `sir_df()`, `ggplot_sir()`, `geom_sir()`, `labels_sir_count()`, `antibiogram()`, `wisca()`, and `bug_drug_combinations()` to interpret the 'I' category correctly per guideline. Functions that return results per category also accept `guideline = NULL` to keep S, I, and R separate, while functions that return a single proportion or count give an informative error.
   * When EUCAST is assumed because neither the `guideline` argument nor the `AMR_guideline` option is set, a message explains how to change this, once per session and not in R Markdown or Quarto documents
