ClickHouse uses Calendar Versioning with the format Year.Month.Patch.Build (e.g., 25.8.4.13).

A new minor release is published approximately every month. The last three minor releases are supported with bug and security fixes.

Twice a year, typically in March and August, minor releases are designated Long-Term Support (LTS). Such releases are supported for 1 year.

More information is available on the ClickHouse website.

You should be running one of the supported release numbers listed above in the rightmost column.
