 ### What version of ClickHouse does ClickHouse Cloud use?
 
 Clickhouse Cloud continuously upgrades your service to a newer version. After publishing a core database version in the open source, we do additional validation in our cloud staging environment, which typically takes 6-8 weeks before rolling out to production. The rollout is phased out by cloud service provider, service type, and region.
