Hi @Sawyerxu
This question is releated to the 4.1.1 version of MetaPhlAn (see Announcing MetaPhlAn 4.1.1 release). The Jun23 database is still the latest, the databases that were uploaded (mpa_vJun23_CHOCOPhlAnSGB_202403 and mpa_vOct22_CHOCOPhlAnSGB_202403) are related to a fix in the taxonomic labels of some SGBs in either Jun23 or Oct22. However, the SGBs you will find in the updated databases are still the same. To update to the latest fixed taxonomy database you can use metaphlan --install --force_download
