 * Updated the prevalence calculation to include genera from the World Health Organization's (WHO) Priority Pathogen List
 * Improved algorithm of `first_isolate()` when using the phenotype-based method, to prioritise records with the highest availability of SIR values
 * `scale_y_percent()` can now cope with ranges outside the 0-100% range
+* Support for new Dutch national MDRO guideline (SRI-richtlijn BRMO, Nov 2024)
 
 ## Other
 * Greatly improved `vctrs` integration, a Tidyverse package working in the background for many Tidyverse functions. For users, this means that functions such as `dplyr`'s `bind_rows()`, `rowwise()` and `c_across()` are now supported for e.g. columns of class `mic`. Despite this, this `AMR` package is still zero-dependent on any other package, including `dplyr` and `vctrs`.
