The 26.5.x line is now live. If you're tracking ClickHouse releases closely, this is the third distinct minor line active simultaneously — 26.3.x (LTS), 26.4.x, and now 26.5.x. That's a fast cadence for a database, and it pays to be deliberate about which track your infrastructure is following. Release details are on GitHub. The 26.3 LTS remains the conservative choice for production; 26.5.x is fresh enough that you'd want to hold for a point or two before rolling it widely.
