Version 0.9.0

For this specific version, nothing to mention.
Since version 0.3.0, CHECK returns a NOTE for having a data directory over 3 MB. This is needed to offer users reference data for the complete taxonomy of microorganisms - one of the most important features of this package.
Since version 0.8.0, this package writes lines to [library path]/AMR/mo_history/mo_history.csv when using the as.mo() function, in the exact same way (and borrowed from) the extrafont package on CRAN (version 0.17) writes to the user library path. Users are notified about this with a message(), and staged install on R >= 3.6.0 still works. The CSV file is never newly created or deleted by this package, it only changes this file to improve speed and reliability of the as.mo() function. See the source code of functions set_mo_history() and clear_mo_history() in file R/mo_history.R.
