Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution.

Antes de la 83.0.0, FileList aplicaba las directivas de exclusión, exclusión global, exclusión recursiva y poda de MANIFEST.in al hacer coincidir patrones glob compilados con nombres de archivo en disco sin normalización Unicode, por lo que en macOS APFS o HFS+ un nombre de archivo NFD podría eludir una regla de exclusión NFC y ser empaquetado en una distribución de origen.
