Release channel
ClickHouse Private follows the slow (deferred) release channel of ClickHouse Cloud, the most conservative of the Cloud channels, intended for risk-averse deployments. A ClickHouse version only becomes a candidate for a ClickHouse Private release once it has started rolling out to the slow channel in Cloud, which is roughly four weeks after the same version starts rolling out to the fast channel.
Reaching the slow channel does not release a version for ClickHouse Private. ClickHouse Private sits at the conservative end of the slow channel: every version goes through our own validation before it is released, so it lands after the Cloud slow rollout has begun.
The ClickHouse Cloud release status page tracks where each ClickHouse version sits in that rollout, and is the best indicator of which versions are approaching a ClickHouse Private release. Note that its dates describe the Cloud rollout only, and no date on that page is a commitment for ClickHouse Private. The tables below and the Changelog are authoritative for what ClickHouse Private actually ships.

Notes
- The operator Helm chart version (
1.20930.1) differs from the operator image tag (main-1.20930.1). Use the Helm chart version when installing viahelm installand the image tag when copying container images. - The ClickHouse server and keeper tags are listed so you can mirror those images into your registry. You do not normally pass them to Helm: each
onprem-clickhouse-clusterchart version pins the tested and validated pair for its release. FIPS is the exception, as below. - FIPS builds append
-fipsto the standard image tags for server, keeper, and operator. There is a single Helm chart per component – the FIPS variant is selected by the image tag, not by a different chart version.
