### What version of ClickHouse does ClickHouse Cloud use?

26
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.

We offer a "Fast" Release Channel for subscribing to updates ahead of the regular release schedule. Access to early upgrades is recommended only for non-production environments and can be requested by logging a support ticket.

If you rely on functionality in the earlier version, you can, in some cases, revert to the previous behavior using your service's compatibility setting.
