Le build di MySQL Community Server 9.0.0 sono preparate per tutte le principali distribuzioni Linux, FreeBSD, macOS e Windows. Nell'ambito del modello di rilascio implementato lo scorso anno, MySQL 9.0 \u00e8 classificato nelle branche 'Innovation', a cui si aggiungeranno anche i rilascio significativi successivi MySQL 9.1 e 9.2. Le branche Innovation sono consigliate per coloro che desiderano accedere anticipatamente a nuove funzionalit\u00e0, vengono pubblicate ogni 3 mesi e sono supportate solo fino alla pubblicazione del successivo rilascio significativo (ad esempio, dopo l'uscita del ramo 9.1, il supporto per il ramo 9.0 verr\u00e0 interrotto). Circa un anno dopo, \u00e8 previsto un rilascio LTS, raccomandato per implementazioni che richiedono prevedibilit\u00e0 e un lungo mantenimento del comportamento invariato.
