A routine maintenance day for ClickHouse: three backport releases in the same morning, covering the current 26.9 stable, the older 26.7 stable, and the 26.3 LTS that long-lived deployments tend to pin to. There's no feature story here — these are the backport trains doing their job — but if you run ClickHouse in production it's the cue to check which line you're on and pull the matching patch.
